Technical Field

The present invention relates to a recessed lamp device in which light is radiated from a grille of a vehicle.

Background

Generally, a vehicle includes one or more lamps (exterior lamps) to enable a good view of an object in a traveling direction at night or to inform a driver of another vehicle or a pedestrian about a traveling state of the vehicle. For example, each vehicle is equipped with a headlamp (each headlamp is also referred to as a lamp (or headlight)) for illuminating a road in front of the vehicle.

The lamps mounted on the vehicle may be classified into headlamps, fog lamps, turn indicators, brake lamps, backup lamps, etc., which may be differently arranged according to the direction of light radiated toward the road surface.

Such a vehicular lamp can provide identification by emitting light radiated from a bulb in a forward direction. In recent years, light guides have been applied to improve exterior designs so that light can be radiated while having a specific image.

However, the space of the vehicle for accommodating the lamps (e.g., the head lamp or the tail lamp) is limited. Therefore, information cannot be exchanged using the vehicle lamp, and there is a limitation from a design point of view.

The contents described as the related art are provided only for the background of aiding understanding of the present invention and should not be considered to correspond to the prior art known to those of ordinary skill in the art.

Hereinafter, a recessed vehicular lamp device according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is a schematic view showing a recessed vehicle lamp apparatus according to an embodiment of the present invention, fig. 2 to 6 are schematic views for explaining the recessed vehicle lamp apparatus shown in fig. 1, and fig. 10 and 11 are schematic views showing messages transmitted by the recessed vehicle lamp apparatus shown in fig. 1.

In the recessed lamp apparatus for a vehicle according to the present invention shown in fig. 1 and 2, an optical module 100 for realizing illumination of a vehicle is provided in a grill 200 to radiate light of the optical module 100 through the grill 200. Light can be radiated from the grill 200 by providing the optical module 100 radiating light in the grill 200 provided in the vehicle so that the light from the optical module 100 is radiated to the outside of the vehicle through the grill 200. That is, when the optical module 100 does not radiate light, the grill 200 serves as an exterior design according to its pattern shape, and when the optical module 100 radiates light, light is radiated from the grill 200, thereby making the grill 200 useful for illuminating the vehicle.

Specifically, in the present invention, the pattern shape of the grating 200 and the shape of the radiation area 110 of the optical module 100 radiating light are formed to be the same. As shown in fig. 1, by forming the pattern shape of the grating 200 and the shape of the radiation area 110 of the optical module 100 radiating light to be the same, the pattern design of the grating 200 can be maintained and the sense of variation caused by the light radiation from the optical module 100 can be reduced.

That is, the design of the grating 200 may be determined by arranging the pattern of the grating 200 in a specific shape. The pattern of the grid 200 is an important factor in representing the overall design of the grid 200. When light is radiated through the optical module 100, if the shape of the radiation area 110 does not correspond to the pattern shape of the grating 200, a sense of difference may be generated and the design of the grating 200 may be deteriorated.

Accordingly, by forming the pattern shape of the louver 200 and the shape of the radiation area 110 of the optical module 100 to be the same, even if light is radiated through the optical module 100, light is radiated in the same shape as the pattern shape of the louver 200, thereby maintaining the design of the louver 200 and improving the aesthetic impression.

Here, the grating 200 may include a plurality of mesh plates 210 having the same pattern shape, and the optical module 100 may be disposed at each of some or all of the plurality of mesh plates 210. As shown in fig. 1, when the grating 200 includes a plurality of mesh plates 210, all of the mesh plates 210 may have the same shape. As for the shape of the mesh plate 210, various shapes such as a polygonal shape and a circular shape may be applied.

Here, the optical module 100 may be disposed on the mesh plates 210 of the grating 200 to radiate light from the respective mesh plates 210 when the light of the optical module 100 is radiated. That is, among the plurality of mesh plates 210 forming the grating 200, the mesh plate 210 provided with the optical module 100 is configured such that the light of the optical module 100 is radiated from the mesh plate 210, without the mesh plate 210 provided with the optical module 100 maintaining its own design. Accordingly, light may be radiated from the optical module 100 according to the number and position of the mesh plates 210, in which the optical module 100 is disposed, among the plurality of mesh plates 210, thereby diversifying the design of the grating 200.

That is, when the optical modules 100 are provided at all the mesh plates 210 of the grating 200, light is radiated from the entire area of the grating 200, thereby securing a light emission amount and intuitively implementing an illumination function. On the other hand, when the optical module 100 is disposed on some of the mesh plates 210 of the grating 200, light is radiated from a partial area of the grating 200, thereby improving design sensitivity. As an embodiment, a bent shape such as a "<" shape may be implemented as shown in fig. 1. Various designs may be achieved by selectively disposing the optical module 100 on the plurality of mesh plates 210 to radiate light of the optical module 100 from the mesh plates 210.

In the present invention, the pattern shape of the grating 200 and the shape of the radiation area 110 of the optical module 100 may be diamond shapes. Since the pattern shape of the grill 200 and the irradiation region 110 correspond to each other in a diamond shape, a linear design can be realized, and the pattern of the grill 200 can be visually recognized when the grill 200 is viewed from the outside. In addition, by linearly implementing the pattern image of the grating 200, when the light of the optical module 100 is radiated through the grating 200 to transmit the message, the message can be intuitively recognized.

On the other hand, as shown in fig. 1 and 3, when the optical module 100 implementing the vehicle lighting is disposed in the grill 200, the mesh plate 210 may include a plurality of radiation regions 110 forming a mesh shape, the light of the optical module 100 may be radiated to the outside through the perforation holes 111 formed in the radiation regions 110, and the entire area of the perforation holes 111 may be at least greater than 1/2 of the entire area of the radiation regions 110. That is, the grill 200 provided in the vehicle includes the optical module 100 for radiating light, and the light radiated from the optical module 100 is radiated to the outside through the grill 200, thereby enabling the light to be radiated from the grill 200.

Here, the light of the optical module 100 is radiated to the outside through the perforated hole 111 formed in the radiation region 110. The perforation holes 111 are opening portions for allowing light to be emitted from the inside to the outside of the grill 200. The radiation of light from the grating 200 may be achieved by radiating light radiated from the optical module 100 to be emitted to the outside through the perforated holes 111.

That is, the radiation area 110 of the optical module 100 is an area where light of the optical module 100 moves. The light transmittance increases when the area of the perforation holes 111 increases with respect to the entire area of the irradiation region 110, and the light transmittance decreases when the area of the perforation holes 111 decreases with respect to the entire area of the irradiation region 110. On the other hand, when the area of the perforation 111 is increased with respect to the entire area of the radiation area 110, the inside of the grid 200 can be seen more specifically from the outside. Therefore, if the perforation 111 is too large, the design of the grill 200 may be deteriorated.

Therefore, by forming the entire area of the perforation holes 111 to be at least 1/2 larger than the entire area of the radiation region 110, the transmission of light radiated from the optical module 100 can be ensured, and the inside of the grating 200 is not visible from the outside to prevent the design of the grating 200 from being deteriorated.

Here, the total area of the perforation holes 111 is preferably set to 60% or more of the total area of the radiation region 110. Even in the case where the entire area of the perforation holes 111 is set to 50% or more of the entire area of the radiation region 110, the transmission of light through the optical module 100 may be ensured to some extent, but the transmission may be reduced by other processes including coating. Therefore, the entire area of the perforation 111 is set to 60% or more.

This is a result obtained by a light distribution efficiency test according to each coordinate. A light distribution efficiency test was performed to check a light intensity measurement value (light distribution degree, [ cd ]) according to each angle (H-horizontal axis, V-vertical axis) on the screen. For example, as an index of the light distribution efficiency test, a light intensity measurement value satisfying a regulation relating to Daytime Running Lights (DRL) can be determined. It can be determined whether the light intensity measurement value according to each coordinate on the screen at the distance 25M satisfies the specification relating to the DRL. In fig. 7 to 9 showing the results of the light distribution efficiency test, the point HV represents an optical center point, which indicates that the light distribution degree is satisfactory in the range of 400cd to 1200cd, U represents upper, D represents lower, L represents left, and R represents right. On this basis, the degree to which the photometric degree is satisfactory can be checked for each coordinate. For example, "10U-5L" is a position coordinate that is 10 degrees upward and 5 degrees leftward from the reference point. It may be checked whether the light intensity value measured at the above-described position is between the minimum target value 80cd and the maximum target value 1200cd to determine whether the condition of the light distribution efficiency is satisfied.

According to the result of the light distribution efficiency test, when the entire area of the perforated hole 111 is 50% or less of the entire area of the radiation region 110, as shown in fig. 7, it can be seen that some of the plurality of points in the radiation region do not satisfy the condition of the light distribution efficiency, and the other points barely satisfy the condition of the light distribution efficiency.

However, as shown in fig. 8, when the total area of the perforation 111 is 60% or more of the total area of the radiation region 110, it can be seen that the light intensity measurement values of all the points satisfy the condition of the light distribution efficiency.

In addition, in a state where the perforation 111 is positioned above the radiation region 110, when the total area of the perforation 111 is 60% or more of the total area of the radiation region 110, as shown in fig. 9, it can be seen that not only the light intensity measurement values of all the points satisfy the condition of the light distribution efficiency, but also a high light intensity can be ensured.

As described above, the entire area of the perforation holes 111 is preferably set to 60% or more of the entire area of the radiation region 110, and when the perforation holes 111 are located at the upper side of the radiation region 110, sufficient light intensity can be secured.

Here, the pattern shape of the grating 200 and the shape of the radiation area 110 of the optical module 100 may be the same as the diamond shape, thereby realizing a linear design of the grating 200 such that the pattern of the grating 200 can be visually recognized when the grating 200 is viewed from the outside. In addition, by linearly implementing the pattern image of the grating 200, when the light of the optical module 100 is radiated through the grating 200 to transmit the message, the message can be intuitively recognized.

On the other hand, as shown in fig. 4, when the optical module 100 implementing the vehicle lighting is disposed in the grill 200, the light of the optical module 100 is radiated to the outside through the perforated holes 111 formed in the radiation region 110, and the perforated holes 111 are located at the upper portion of the radiation region 110, and the non-perforated portion 112 that does not transmit the light may be formed at the lower portion of the radiation region 110. That is, by providing the optical module 100 in the grill 200 disposed in the vehicle and radiating light radiated from the optical module 100 to the outside through the grill 200, the light can be radiated from the grill 200.

That is, since the radiation region 110 is divided into the perforated hole 111 and the non-perforated portion 112, the light radiated from the optical module 100 is radiated to the outside through the perforated hole 111, while in the non-perforated portion 112, the light is not projected to the outside.

Specifically, since the perforated holes 111 are located at the upper portion of the radiation region 110 and the non-perforated portions 112 are located below the perforated holes 111, the grill 200 may look like a jewel when the grill 200 is viewed from the outside. Specifically, the perforated hole 111 is a portion that transmits light of the optical module 100. When the grill 200 is viewed from the outside, the inside of the grill 200 is partially visible through the perforated holes 111. Generally, the grille 200 of the vehicle is disposed at a lower portion of the vehicle. Accordingly, when the grill 200 is viewed from the outside, the grill 200 is viewed from the top to the bottom. By forming the perforated holes 111 at the upper portion of the irradiation region 110 and forming the non-perforated portion 112 at the lower portion of the irradiation region 110, the non-perforated portion 112 is visible through the perforated holes 111 when the grill 200 is viewed from the outside. The grill may look like a gem as the non-perforated portion 112 is visible when the grill 200 is viewed from the outside and the remaining coating on the non-perforated portion is visible, further achieving the luxurious exterior design of the grill 200. In addition, by disposing the perforated hole 111 at an upper portion of the radiation region 110, the light of the optical module 100 is radiated upward after passing through the perforated hole 111, thereby improving visibility of the light.

Also, the perforation holes 111 may occupy 60% of the entire area of the radiation region 110, and the non-perforated portion 112 may be formed in the remaining area except for the perforation holes 111. By setting the entire area of the perforation holes 111 to 60% or more of the entire area of the radiation region 110, the light transmittance can be ensured even if other processes including coating are performed and the light transmittance is reduced. In addition, by forming the non-perforated portion 112 in the remaining area except for the perforated holes 111, it can be easily achieved by the non-perforated portion 112 that the grill 200 looks like a jewel when the grill 200 is viewed from the outside.

On the other hand, when the pattern shape of the grating 200 and the shape of the irradiation region 110 of the optical module 100 are the same as the diamond shape and the entire area of the perforation holes 111 is at least 1/2 of the entire area of the irradiation region 110, the perforation holes 111 may be formed in a pentagonal shape, and the non-perforated portion 112 may be formed in a triangular shape according to the remaining area of the irradiation region 110.

By forming the pattern shape of the grating 200 and the shape of the radiation area 110 of the optical module 100 to be the same as the diamond shape described above, it is possible to realize a linear design of the grating 200, thereby intuitively recognizing the pattern of the grating 200 when the grating 200 is viewed from the outside. In addition, since the pattern image of the grating 200 is linearly implemented, when the light of the optical module 100 is radiated through the grating 200 to transmit the message, the message can be intuitively recognized.

In addition, by forming the perforation holes 111 such that the entire area thereof is at least 1/2 of the entire area of the radiation region 110, the perforation holes 111 may be formed in a pentagonal shape, and the non-perforation portions 112 may be formed in a triangular shape according to the remaining area of the radiation region 110. That is, since the shape of the radiation region 110 of the optical module 100 is a diamond shape and the entire area of the perforation hole 111 is at least 1/2 of the entire area of the radiation region 110, the perforation hole 111 may be formed in a pentagonal shape. By forming the perforation holes 111 in a pentagonal shape in a state where the triangular-shaped non-perforation portions 112 prevent light from being radiated below the perforation holes 111, it is possible to secure sufficient light transmittance in the diamond-shaped radiation regions 110, and it is possible to easily form the grating 200 to look like a gem while minimizing a sense of difference and realizing a luxurious design.

During this, when the optical module 100 for implementing the vehicle lighting is provided in the grill 200, the optical module 100 may include: a light source 120, a reflector 130, and a lens 140, the light source 120 radiating light; the reflector 130 reflects light of the light source; the lens 140 forms a radiation area 110 in which light reflected by the reflector 130 is emitted to the outside, and the lens 140 is formed in the same shape as the pattern shape of the grating 200.

Here, the light source 120 may be formed of a Light Emitting Diode (LED), and the reflector 130 may be formed of a mirror and bent to change a direction of light radiated from the light source such that the light moves to the outside. The lens 140 may be disposed in front of the reflector 130 to emit light to the outside and form the same shape as the pattern shape of the grating 200 to maintain the pattern design of the grating 200 and reduce the sense of difference caused by the light radiation from the optical module 100.

The lens 140 may include a plurality of optical components 144 protruding outward, each optical component 144 having a respective one of the radiation zones. Since the optical member 144 protrudes from the lens 140, when the grill 200 is viewed from the outside, a gorgeous image can be realized by the reflected light. To this end, each optical component 144 is preferably arranged to correspond to a respective one of the radiation areas 110.

Specifically, as shown in fig. 5 and 6, the optical member 144 may include upper and lower side surfaces 144a and 144b that protrude at an angle from positions spaced apart from each other and extend to converge with each other, while the radiation region 110 includes a perforated hole 111 at an upper portion thereof through which light is transmitted and a non-perforated portion 112 at a lower portion thereof through which light is not transmitted.

Since the optical member 144 includes the upper side surface 144a and the lower side surface 144b connected to each other in an inclined state, when the grill 200 is viewed from the outside, sunlight is reflected by the upper side surface 144a and not by the lower side surface 144b, thereby generating an image difference between the upper side surface 144a and the lower side surface 144 b. In addition, since the perforation holes 111 are formed at the upper portion of the irradiation region 110 to transmit light and the non-perforated portion 112 is formed at the lower portion of the irradiation region 110 to prevent the transmission of light, the non-perforated portion 112 is visible when the grill 200 is viewed from the outside, and thus, the grill 200 looks like a jewel.

For this reason, when the upper side surface 144a and the lower side surface 144b of the optical member 144 extend at the same angle to converge to each other, a point (a) at which the radiation region 110 is divided into the perforated hole 111 and the non-perforated portion 112 may be disposed lower than a point (b) at which the upper side surface 144a and the lower side surface 144b of the optical member 144 are connected to each other. Accordingly, the total area of the perforation apertures 111 may be at least greater than 1/2 of the total area of the radiation region 110.

That is, since the upper side surface 144a and the lower side surface 144b of the optical member 144 extend at the same angle so that the optical member 144 has an isosceles triangle shape and the point (a) at which the radiation region 110 is divided into the perforated hole 111 and the non-perforated portion 112 is arranged lower than the point (b) at which the upper side surface 144a and the lower side surface 144b of the optical member 144 are connected to each other, when the grill 200 is viewed from the outside, the visibility of the non-perforated portion 112 through the perforated hole 111 can be ensured.

Specifically, the grille 200 of the vehicle is generally disposed at the lower portion of the vehicle. Accordingly, when the grill 200 is viewed from the outside, the grill 200 is viewed from the top down. When the grille 200 of the vehicle is viewed from the outside, sunlight is reflected by the upper side surface 144a of the optical member 144 formed on the lens 140 and is not reflected by the lower side surface 144b of the optical member 144, thereby realizing a design according to a difference in reflected image between the upper side surface 144a and the lower side surface 144 b. Further, since the non-perforated portion 112 is visible through the perforated holes 111 and the remaining coating of the non-perforated portion 112 is visible when the inside of the grill 200 is viewed through the upper side surface 144a of the optical member 144, the grill 200 may look like a jewel, thereby achieving the luxurious exterior design of the grill 200. In addition, since the point (a) at which the radiation region 110 is divided into the perforated holes 111 and the non-perforated portion 112 is disposed lower than the point (b) at which the upper side surface 144a and the lower side surface 144b of the optical member 144 are connected to each other, the entire area of the perforated holes 111 can be increased, thereby ensuring the light transmittance of the optical module 100 when the mesh plate 210 is used as illumination.

On the other hand, the shape of the optical member 144 may be the same as the pattern shape of the grating. By forming the shape of the optical member 144 to be the same as the pattern shape of the grating 200, the pattern design of the grating 200 can be maintained, and the sense of difference according to the light radiation from the optical module 100 can be reduced. Since the pattern shape of the grating 200 and the shape of the optical member 144 are the same, the planned design can be maintained. Even if light is radiated through the optical module 100, light can be radiated in the same shape as the pattern shape of the grill 200, thereby maintaining the design of the grill 200 and improving the aesthetic impression.

Specifically, the pattern shape of the grating 200, the shape of the lens 140, the shape of the irradiation region 110, and the shape of the optical member 144 may be the same as the diamond shape. Since the shape of the optical member 144, the pattern shape of the grill 200, the shape of the irradiation region 110, and the shape of the lens 140 correspond to each other in a diamond shape, a linear design can be achieved so that the pattern of the grill 200 is visually recognized when the grill 200 is viewed from the outside. In addition, since the shape of the optical member 144 corresponds to a diamond shape, when the grill 200 is viewed, the design of the diamond shape can be clearly expressed. By linearly implementing the pattern image of the grating 200, when the light of the optical module 100 is radiated through the grating 200 to transmit the message, the message can be intuitively recognized.

On the other hand, the lens 140 may include: a transmissive layer 141, a reflective layer 142, and a coating layer 143, the transmissive layer 141 being disposed on an outer side of the lens and transmitting light; the reflective layer 142 is bonded to the inner side of the transmissive layer 141 and reflects light; the coating layer 143 is bonded to the inner side of the reflective layer 142 and has a lower light transmittance than the transmissive layer 141, and the reflective layer 142 and the coating layer 143 may include a plurality of perforation holes 111 spaced apart from each other, each perforation hole 111 being opened toward the transmissive layer 141 at the same position of the reflective layer 142 and the coating layer 143 to form a plurality of radiation regions 110.

As described above, the lens 140 includes the transmissive layer 141, the reflective layer 142, and the overcoat layer 143. Here, the transmissive layer 141 is formed of a transparent plastic material, the reflective layer 142 is formed of a material capable of reflecting light and coated on the transmissive layer 141, and the coating layer 143 is formed of a material having a low light transmittance and coated on the reflective layer 142. Here, the reflective layer 142 and the coating layer 143 are formed of the same material as the grill 200 to impart the same feeling as the grill 200. That is, since the reflective layer 142 is visible through the transmissive layer 141 when the grill 200 is viewed from the outside, the grill 200 may look like a jewel, and the reflective layer 142 and the coating layer 143 may prevent the inside of the grill 200 from being visible.

Specifically, the reflective layer 142 and the coating layer 143 include a plurality of perforation holes 111 spaced apart from each other, and each perforation hole 111 is opened toward the transmissive layer 141 at the same position of the reflective layer 142 and the coating layer 143 to form a plurality of radiation regions 110. That is, after passing through the transmissive layer 141 via the plurality of perforation holes 111 formed in the reflective layer 142 and the overcoat layer 143, light radiated from the optical module 100 may be emitted to the outside. Since the perforated hole 111 (the perforated hole 111 is an opening portion that allows light radiated from the optical module 100 to be emitted to the outside) is formed at the same position of the reflective layer 142 and the coating layer 143 and is opened to the transmissive layer 141, the light can be emitted to the outside after passing through the reflective layer 142 and the coating layer 143.

By forming the perforated holes 111 in the reflective layer 142 and the coating layer 143 while the transmissive layer 141, the reflective layer 142, and the coating layer 143 of the lens 140 are formed to have the same feeling as the grating 200, light radiated from the optical module 100 can be radiated to the outside through the perforated holes 111, thereby implementing a lighting function.

In addition, the lens 140 may include: an outer lens 140-1 and an inner lens 140-2, the outer lens 140-1 including a transmissive layer 141, a reflective layer 142, and a coating layer 143; the inner lens 140-2 is disposed inside the outer lens 140-1 and has a plurality of protrusions or grooves to scatter light radiated from the optical module 100.

When the lens 140 includes the outer lens 140-1 and the inner lens 140-2, the outer lens 140-1 may be formed to have the same feeling as the grating 200, and the inner lens 140-2 may be configured to scatter light radiated from the optical module 100. Here, since the inner lens 140-2 is disposed inside the outer lens 140-1 and has a plurality of protrusions or grooves, light radiated from the optical module 100 may be scattered by the plurality of protrusions or grooves, thereby improving visibility of the light.

On the other hand, fig. 10 and 11 are schematic views illustrating transmission of a message by the hidden vehicle lamp device shown in fig. 1. The optical module 100 for implementing vehicle lighting is disposed in the grill 200 to radiate light through the grill 200. The grid may include a plurality of optical modules 100 configured to be individually switched on or off. By controlling the optical modules 100 to be individually turned on or off, the position of light emitted from the grill 200 and the intensity of light can be diversified, thereby implementing various lighting functions.

Specifically, the recessed vehicle lamp device may further include a controller 300, the controller 300 individually controlling the turn-on or turn-off of the optical module 100. The controller 300 may perform control such that a plurality of optical modules 100 are sequentially turned on or off or only some of the optical modules are turned on or off to implement an image for communication. Here, the controller 300 may control the turn-on or turn-off of the optical module 100 according to a user's operation or by receiving various sensor signals. When the controller 300 controls the plurality of optical modules 100 included in the grill 200 to be sequentially turned on or off from one direction to another or from another direction to one direction, an elegant design of lighting may be achieved and a direction signal may be transmitted to a driver of another vehicle or a pedestrian according to circumstances. In addition, the controller 300 may control the plurality of optical modules 100 such that only some of the optical modules 100 are turned on or off to generate a message such as text or graphics, so that various messages for communication may be delivered.

In the recessed lamp apparatus for a vehicle having the above-described structure, light is radiated from the grill 200 of the vehicle, and when light is not radiated, the shape of the radiation area 110 and the pattern shape of the grill 200 are formed to be identical to each other, so that the design of the grill 200 can be maintained.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
