When the lamp 10 of the above embodiment is used, when air such as outside air enters the airflow channel 150 through the air inlet 120 and circulates, the air circulating in the airflow channel 150 can be irradiated by the sterilizing light 210 emitted by the optical sterilizing element 200, so that bacteria or viruses in the air can be killed, and the purified air flows out from the air outlet 130, thereby ensuring the air safety of the environment. Meanwhile, the sterilizing light 210 emitted by the optical sterilizing member 200 irradiates the converting structure 300, the sterilizing light 210 is converted into the illuminating light 330 by the converting structure 300, and the illuminating light 330 is emitted to the outside through the light emitting area 140, so that the outside can be illuminated. Compared with the conventional lamp 10, the lamp 10 of the embodiment has the functions of sterilization and illumination, can provide illumination while sterilizing air, and is more convenient to use. Moreover, the conventional lamp 10 mainly integrates the sterilization light source and the illumination light source to realize the sterilization and illumination functions, the conventional lamp 10 can perform sterilization and illumination simultaneously only by turning on the sterilization light source and the illumination light source simultaneously, the lamp 10 of the above embodiment can realize sterilization and illumination simultaneously only by means of the optical sterilization part 200, and the energy consumption is low. The conventional lamp 10 is provided with a sterilization light source and an illumination light source at the same time, the internal structure is relatively complex, the lamp 10 of the above embodiment is provided with only one optical sterilization part 200, and the lamp is simple and compact in structure and relatively low in cost.

It should be noted that the optical sterilizing element 200 may be any component capable of Emitting the sterilizing light 210, preferably an ultraviolet light source, such as L ED (L light Emitting Diode) ultraviolet lamp, a mounting hole communicating with the first cavity 110 may be provided on the housing 100, the optical sterilizing element 200 may be mounted in the mounting hole such that the light Emitting end of the optical sterilizing element 200 fully or partially extends into the first cavity 110, and the input end of the optical sterilizing element 200 may extend out of the mounting hole and be connected to an external power source, a sealing member such as a corresponding sealing ring or a sealing strip may be provided between the optical sterilizing element 200 and the inner wall of the mounting hole in order to ensure that the optical sterilizing element 200 and the housing 100 can be tightly sealed to avoid air leakage, the illuminating light 330 may be any light capable of serving as an illuminating function, and in other embodiments, the sterilizing light 210 may be converted into other light bands by the converting structure 300, such as the invisible light outlet, the light outlet 140, the light outlet, and the light outlet and the like, which allow the illuminating light 330 to pass through.

The conversion structure 300 converts the sterilization light 210 into the illumination light 330, and can change the wavelength of the sterilization light 210 through the lens, and can also excite the corresponding fluorescent substance through the sterilization light 210, and can also convert the sterilization light 210 into the corresponding illumination light 330 through the combination of the lens and the fluorescent substance only by satisfying the requirement.

Referring to fig. 1 and 2, in an embodiment, the conversion structure 300 includes a first fluorescent layer 310 disposed corresponding to the light emitting area 140 and capable of converting the sterilizing light 210 into the illuminating light 330, and the first fluorescent layer 310 is disposed opposite to the optical sterilizing member 200 at an interval. Thus, the sterilizing light 210 emitted by the optical sterilizing member 200 firstly passes through the air flow channel 150, and then irradiates the first fluorescent layer 310 after sterilizing the air, so as to excite the fluorescent substance in the first fluorescent layer 310, and further emit the illuminating light 330 with a longer wavelength, thereby illuminating. The color of the fluorescent material in the first fluorescent layer 310 can be flexibly adjusted according to the use requirement, so that the color of the illumination light 330, such as green or yellow, can be changed accordingly; of course, it is also possible to partition the first fluorescent layer 310 and fill different areas with fluorescent substances of different colors, so that the fluorescent substances of different areas emit different colors of illumination light 330 after being excited; meanwhile, different fluorescent substances can be selected to emit invisible light in other bands, such as infrared bands. The first fluorescent layer 310 may be configured to be circular or square, the shape and size of the first fluorescent layer 310 may match the shape and size of the light emitting area 140, and the first fluorescent layer 310 may be fixed in the light emitting area 140 by clamping, bonding, or the like. The sterilizing light rays 210 are preferably irradiated perpendicularly or nearly perpendicularly onto the first fluorescent layer 310, the best excitation effect on the fluorescent material of the first fluorescent layer 310 is obtained, and the intensity of the illuminating light rays 330 is high; of course, the sterilizing light rays 210 may be obliquely irradiated onto the first fluorescent layer 310, and only the illuminating light rays 330 need to be emitted. The size of the outline of the first fluorescent layer 310 can be larger than the size of the outline of the light emergent area 140, so that the contact area between the germicidal light rays 210 and the first fluorescent layer 310 is increased, leakage of the germicidal light rays 210 from the light emergent area 140 is avoided, and safety is guaranteed.

Referring to fig. 1 and fig. 2, further, the lamp 10 further includes a light-transmitting member 320, and at least a portion of the light-transmitting member 320 is disposed between the first fluorescent layer 310 and the optical sterilizing member 200. Thus, the sterilizing light 210 emitted by the optical sterilizing member 200 is firstly irradiated onto the light transmitting member 320 and then irradiated onto the first fluorescent layer 310, so that the rapid aging of the first fluorescent layer 310 can be avoided, and the service life of the first fluorescent layer 310 can be prolonged. Meanwhile, the light-transmitting member 320 can also provide support for the arrangement of the first fluorescent layer 310, and the first fluorescent layer 310 can be installed and fixed in the light-emitting area 140 only by arranging the light-transmitting member 320 in the light-emitting area 140 in a clamping or bonding manner. In addition, the light-transmitting member 320 can separate the first fluorescent layer 310 from the air flow channel 150, so as to prevent the first fluorescent layer 310 from being damaged due to impact of air flow on the first fluorescent layer 310, and ensure durability and reliability of the first fluorescent layer 310. Wherein, at least part of the light-transmitting member 320 is disposed between the first fluorescent layer 310 and the optical sterilizing member 200, which means that the first fluorescent layer 310 can be disposed inside the light-transmitting member 320, or the first fluorescent layer 310 can be disposed on a side of the light-transmitting member 320 away from the optical sterilizing member 200; preferably, the first fluorescent layer 310 is disposed inside the light-transmitting member 320, so that the first fluorescent layer 310 is prevented from contacting with the outside air, and the service life of the first fluorescent layer 310 is prolonged. The light-transmitting member 320 may be made of glass or light-transmitting resin, and only needs to satisfy the light-transmitting requirement.

Referring to fig. 3 and 4, in an embodiment, the conversion structure 300 includes a conversion lens 340 capable of changing a propagation path of the germicidal light rays 210, and a second fluorescent layer 350 disposed corresponding to the light-emitting area 140, and the conversion lens is capable of emitting the illumination light 330 after the germicidal light rays 210 of the converted propagation path are irradiated to the second fluorescent layer 350. Like this, the sterilization light 210 that optical sterilization piece 200 sent firstly passes through air flow channel 150, shine to conversion lens 340 again after accomplishing the sterilization of air, utilize conversion lens 340 to make sterilization light 210's propagation path change, thereby make sterilization light 210 after the propagation path changes can be accurate shine to second fluorescent layer 350 on, thereby arouse the fluorescent material in the second fluorescent layer 350, and then send the longer illumination light 330 of wavelength and follow light-out zone 140 and jet out, thereby can throw light on. The propagation path of the sterilization light 210 can be changed by using the conversion lens 340, so that the position of the second fluorescent layer 350 can be flexibly changed, the propagation path of the illumination light 330 can be correspondingly changed, the emergent position or the emergent angle of the illumination light 330 can be flexibly adjusted, the installation position or the installation angle of the lamp 10 can be reasonably adjusted, the universality is higher, and the use is more convenient.

In one embodiment, the optical sterilizing member 200 may be disposed at the left side of the housing 100, the conversion lens 340 may be disposed at the right side of the housing 100, the conversion lens 340 may be used to change the propagation path of the sterilizing light 210 irradiated from the left side, so that the propagation path of the sterilizing light 210 is changed to be downward, the sterilizing light 210 propagating downward can be directly irradiated onto the second fluorescent layer 350 disposed below the housing 100, the fluorescent substance in the second fluorescent layer 350 is excited, and the illuminating light 330 is emitted downward, and the illuminating light 330 illuminates the lower side after passing through the light exit area 140 disposed at the lower portion of the housing 100. Of course, in other embodiments, the optical sterilizing member 200 is disposed on the left side of the housing 100, the conversion lens 340 is disposed on the right side of the housing 100, the conversion lens 340 is used to change the propagation path of the sterilizing light 210 irradiated from the left side, and the conversion lens 340 can also be used to change the propagation path of the sterilizing light 210 to be upward propagated, so that the upward propagated sterilizing light 210 can be directly irradiated onto the second fluorescent layer 350 disposed above the housing 100, the fluorescent substance in the second fluorescent layer 350 is excited, and the illuminating light 330 is emitted upward, and the illuminating light 330 illuminates the upper side after passing through the light emitting area 140 disposed on the upper portion of the housing 100.

The color of the fluorescent material in the second fluorescent layer 350 can be flexibly adjusted according to the use requirement, so that the color of the illumination light 330, such as green or yellow, can be changed; of course, it is also possible to partition the second fluorescent layer 350 and fill different areas with fluorescent substances of different colors, so that the fluorescent substances of different areas emit different colors of illumination light 330 after being excited; meanwhile, different fluorescent substances can be selected to emit invisible light in other bands, such as infrared bands. The second fluorescent layer 350 may be disposed in a circular or square shape, and the size and shape thereof may be matched with those of the light exiting region 140. The conversion lens 340 may be made of a transparent material such as glass or resin.

The change of the propagation path of the sterilizing light 210 by the conversion lens 340 can be realized by refraction, total reflection and other ways, and only the propagation path of the sterilizing light 210 needs to be changed; preferably, the method is implemented by using total reflection, and the propagation paths of all the sterilizing light rays 210 can be changed to the greatest extent without loss, so that enough sterilizing light rays 210 are irradiated on the second fluorescent layer 350, and the second fluorescent layer 350 can be ensured to be excited, thereby ensuring the intensity of the illuminating light 330.

Referring to fig. 3 and 4, in one embodiment, the conversion lens 340 includes a light-entering sidewall 341, a conversion sidewall 342, and a light-exiting sidewall 343 disposed corresponding to the light-exiting region 140. The light inlet sidewall 341 is perpendicular or approximately perpendicular to the germicidal light rays 210. Thus, the sterilizing light 210 emitted by the optical sterilizing element 200 passes through the airflow channel 150 to sterilize the air, and then is directly emitted to the light inlet sidewall 341, so that the sterilizing light 210 enters the conversion lens 340 to the maximum, thereby preventing the sterilizing light 210 from being emitted on the light inlet sidewall 341 and ensuring the intensity of the sterilizing light 210. The converting sidewall 342 and the germicidal light rays 210 may be disposed at an included angle, so that the converting sidewall 342 can make the germicidal light rays 210 generate total reflection, and make the germicidal light rays 210 after total reflection vertically or approximately vertically transmit to the light-emitting sidewall 343, and the second fluorescent layer 350 is disposed near the light-emitting sidewall 343. Thus, when the sterilizing light 210 entering the converting lens 340 irradiates the converting sidewall 342, the converting lens 340 belongs to a light-tight medium, and the outside air belongs to a light-sparse medium, when the included angle between the sterilizing light 210 and the normal direction of the converting sidewall 342 is greater than or equal to the critical angle (i.e. the incident angle is greater than or equal to the critical angle), the sterilizing light 210 is totally reflected on the converting sidewall 342, thereby changing the propagation path of the sterilizing light 210, so that the sterilizing light 210 irradiates the second fluorescent layer 350 disposed near the light-emitting sidewall 343, and by exciting the fluorescent material in the second fluorescent layer 350, the illuminating light 330 with a longer wavelength is emitted, and further, the illuminating light 330 is emitted from the light-emitting region 140 for illumination after passing through the light-emitting sidewall 343. The sterilizing light rays 210 are vertically or approximately vertically transmitted to the light-emitting side wall 343, so that as much sterilizing light rays 210 as possible are irradiated onto the second fluorescent layer 350, the excitation effect on the fluorescent substance of the second fluorescent layer 350 is good, and the intensity of the illuminating light 330 is ensured; further, the second fluorescent layer 350 is disposed parallel or approximately parallel to the light-emitting sidewall 343, so that as much of the sterilizing light 210 as possible is irradiated onto the second fluorescent layer 350, and the illuminating light 330 is also irradiated onto the light-emitting sidewall 343 vertically or approximately vertically, thereby preventing the illuminating light 330 from being emitted on the light-emitting sidewall 343, avoiding the loss of the illuminating light 330, and ensuring the intensity of the illuminating light 330.

In one embodiment, the optical sterilizing member 200 is disposed on the left side of the housing 100, the converting lens 340 is disposed on the opposite right side of the housing 100, the sterilizing light 210 irradiated from the left side is vertically irradiated onto the vertically disposed light-entering sidewall 341, so that the sterilizing light 210 smoothly enters the converting lens 340, the sterilizing light 210 is totally reflected when irradiated onto the converting sidewall 342 obliquely disposed with respect to the horizontal plane, so that the propagation path of the sterilizing light 210 is changed to vertically downward propagation, so that the sterilizing light 210 can be vertically irradiated onto the horizontally disposed second fluorescent layer 350, the fluorescent material in the second fluorescent layer 350 is excited, so that the vertically downward illuminating light 330 is generated, and the illuminating light 330 is vertically irradiated onto the horizontally disposed light-exiting sidewall 343, passes through the light-exiting region 140, and is vertically downward outputted out of the housing 100.

The approximately perpendicular or approximately parallel arrangement is considered to be perpendicular or parallel in consideration of the influence of machining errors and mounting errors, and is considered to be within an error tolerance range, for example, the arrangement is considered to be perpendicular when the included angle is 89 ° to 91 °, and the arrangement is considered to be parallel when the included angle is 0 ° to 1 °. The size of the outline of the second fluorescent layer 350 can be larger than the size of the outline of the light-emitting area 140, so that the contact area between the sterilizing light 210 and the second fluorescent layer 350 is increased, leakage of the sterilizing light 210 from the light-emitting area 140 is avoided, and safety is guaranteed. The second fluorescent layer 350 may be disposed inside the conversion lens 340, so that the second fluorescent layer 350 is prevented from being interfered by the outside, and the service life of the second fluorescent layer 350 is prolonged.

Thus, when the conversion lens 340 is disposed in the second cavity 171, the conversion lens 340 or the second fluorescent layer 350 can be simply and conveniently replaced by only removing the second shell 170; of course, in other embodiments, a corresponding openable cover may be disposed on the second housing 170, and the convertible lens 340 or the second fluorescent layer 350 may be replaced by only opening the cover. Meanwhile, the arrangement of the first casing 160 and the second casing 170 also enables the air sterilization and the conversion of the illumination light 330 not to interfere with each other, thereby ensuring that the lamp 10 has good sterilization effect and illumination function. Moreover, the first shell 160 and the second shell 170 are combined to form the shell 100, so that the production difficulty of the shell 100 is reduced, and the production cost is saved. The first casing 160 and the second casing 170 can be detachably connected through clamping, inserting and the like, so that the first casing and the second casing are convenient to disassemble and assemble. Of course, in other embodiments, the first casing 160 and the second casing 170 may be connected by welding or heat fusing.

Further, one side of the conversion lens 340 is positioned to mate with the first housing 160. In this way, the conversion lens 340 is matched with the first housing 160 in a positioning manner, so that accurate installation can be achieved, the position of the conversion lens 340 relative to the optical sterilizing member 200 and the light emergent area 140 is more accurate, the transmission path of the sterilizing light 210 can be accurately changed by the conversion lens 340, and the generated illuminating light 330 can be accurately emitted from the light emergent area 140 for illumination. The positioning matching between the conversion lens 340 and the first housing 160 can be realized by the positioning matching between the positioning pin and the positioning hole, or by the positioning matching between the positioning block and the positioning groove, and only the requirement of accurate installation of the conversion lens 340 can be met. The other side of the conversion lens 340 is fixedly connected to the second housing 170. Thus, through the fixed connection between the conversion lens 340 and the second housing 170, it is ensured that the conversion lens 340 does not shake or shift during the use process, and the stability of the installation position of the conversion lens 340 is ensured, so that the conversion lens 340 can reliably change the propagation path of the sterilizing light 210, and the sterilizing light 210 can irradiate onto the second fluorescent layer 350 to generate the illuminating light 330, and the illuminating light 330 can be accurately emitted from the light emitting area 140. The fixed connection between the conversion lens 340 and the second housing 170 may be realized by a screw connection, a snap connection, or a bolt connection.

Referring to fig. 1 to 4, on the basis of any of the above embodiments, the inner wall of the airflow channel 150 is provided with a guide portion 180 for guiding the air to flow back and forth. Thus, the air in the airflow channel 150 can flow back and forth by the guide part 180, so that the air can stay in the airflow channel 150 for a long enough time, the sterilizing light 210 can fully sterilize and disinfect the air, and the air safety is ensured.

Referring to fig. 1 to 4, in an embodiment, the air inlet 120 and the air outlet 130 are disposed in a staggered manner. So for the flow direction of air is pitch arc or curve, avoids the straight line to flow, has enlarged the area that light 210 that disinfects shines the air, can promote the sterilization effect to the air. And a guide portion 180 is provided on a side wall of the airflow passage 150 opposite to the air inlet 120. Thus, the air entering from the air inlet 120 can collide with the side wall of the air flow channel 150 and swirl or flow backwards under the guiding effect of the guiding part 180, so that the retention time of the air in the air flow channel 150 can be prolonged, and the sterilizing light 210 can sufficiently sterilize and disinfect the air.

The guiding portion 180 may be an arc protrusion disposed on the inner wall of the first cavity 110, at least two arc protrusions may be arranged at intervals or in sequence, and when the air impacts on the arc protrusion, an arc line between the lowest position and the highest position of the arc protrusion can guide the flowing direction of the air, so that the air is swirled or reflowed. The guide portion 180 may be disposed at a position close to the outlet 130, and may allow the air to flow repeatedly, such as whirling or reverse flow, without affecting the air entering the airflow channel 150.

Referring to fig. 1 to 4, on the basis of any of the above embodiments, the optical sterilizing element 200 and the converting structure 300 are disposed at an interval. Thus, the optical sterilizing element 200 and the converting structure 300 are respectively disposed at two sides of the airflow channel 150, so that the sterilizing light 210 emitted by the optical sterilizing element 200 passes through the airflow channel 150 and irradiates the converting assembly after the sterilization is completed. The exit direction of the germicidal light rays 210 is perpendicular or approximately perpendicular to the air flow direction in the air flow channel 150. Thus, on the premise of ensuring the sterilization effect of the sterilization light 210, the propagation distance from the sterilization light 210 to the conversion structure 300 is reduced, so that the loss of the sterilization light 210 can be effectively avoided, and the generated illumination light 330 has sufficient intensity.

In the automobile of the embodiment, when the lamp 10 is used, when air such as outside air enters the airflow channel 150 through the air inlet 120 and circulates, the air circulating in the airflow channel 150 can be irradiated by the sterilizing light 210 emitted by the optical sterilizing element 200, so that bacteria or viruses in the air are killed, the purified air flows out from the air outlet 130, and the air safety in the automobile can be ensured. Meanwhile, the sterilizing light 210 emitted by the optical sterilizing member 200 irradiates the conversion structure 300, the sterilizing light 210 is converted into the illuminating light 330 through the conversion structure 300, and the illuminating light 330 is emitted into the vehicle through the light emitting area 140, so that the vehicle can be illuminated, and the use is more convenient. Moreover, sterilization and illumination can be realized simultaneously only by the optical sterilization part 200, and the energy consumption is low.

Air enters the airflow channel 150, and air blown out by the air conditioning system can be supplied into the airflow channel 150, so that the lamp 10 can participate in internal circulation or external circulation of the air in the vehicle without additionally arranging an air blowing element, the safety of the air in the vehicle is ensured, illumination can be provided, and the air conditioner is economical and environment-friendly.
