Technical Field

The application belongs to the technical field of starry sky roofs, and particularly relates to a twinkling optical machine for a starry sky roof.

Background

The starry sky roof can be a suspended ceiling of interior decoration or an automotive interior ceiling, and a starry sky effect is formed by projecting light onto optical fibers by using an optical machine and then transmitting the light to the suspended ceiling of the interior decoration or the automotive interior ceiling through the optical fibers. The ray apparatus is a set of LED lamp pearl that has the circuit board, and the luminance and the color of control LED lamp pearl realize the effect that needs.

The most common function of the light engine is breathing, i.e. slow on-off switching. For the colored LED lamp beads, the color change is also included, and the red, green and blue are directly switched and gradually changed. However, for the light engine, the most striking is the blinking mode, i.e. part of the stars breathe as if the stars blink eyes.

The existing ray machine flickering is usually realized by additionally arranging a separation blade driven by a motor outside an LED lamp bead. The baffle is provided with random open pores and is positioned in front of the optical fiber coupling surface, the part which is not hollowed out on the baffle gradually shields the optical fiber to realize gradual extinguishment of the light spot, the part which is not hollowed out on the baffle gradually avoids to expose the optical fiber, and the light spot is gradually lightened.

There is a starry sky light projector used for interior decoration, which is a motor directly driving a blocking sheet to shield an optical fiber coupling surface. The shape of the blocking piece is as shown in figure 1, the diameter of the blocking piece is more than twice of the diameter of the optical fiber bundling, and the rotating shaft of the blocking piece is close to the optical fiber bundling head, so that the blocking of partial optical fibers is realized in the rotating process, and the effect of light spot flickering is achieved. However, the size of the baffle is too large, so that the size of the optical machine is large, and the baffle is not suitable for being used on the ceiling of the interior trim of the automobile.

The ray machine that uses on the automotive interior ceiling can not directly use motor drive separation blade to shelter from optic fibre usually, but as shown in figure 2, regard a rectangular shape separation blade as link mechanism, and one end is connected on motor drive's eccentric shaft, and the other end overlaps on a reference column with a groove, rotates through motor drive eccentric shaft, drives the separation blade and makes reciprocating motion to realize the motion of separation blade, realize the scintillation effect that part light spot obviously goes out. By converting the rotation to the reciprocating motion, the size of the optical machine, particularly the thickness of the optical machine, can be reduced, and the optical machine is convenient to use on a starry sky roof of an automobile interior trim.

However, the automotive industry has particularly emphasized reliability, and such reciprocating mechanisms necessarily require a certain clearance between the moving parts, and are undesirable in the automotive industry because of wear of the parts, abnormal noise, and reduced reliability due to long-term operation.

Therefore, there is a need for a light engine suitable for use in the automotive industry that is small and reliable.

Disclosure of Invention

The content of this application provides a starry sky top scintillation light machine, overcomes current scintillation light machine and contains the moving part, the problem that the reliability is low.

The technical scheme of the application is as follows:

the utility model provides a scintillation ray apparatus that starry sky top was used, the housing contains, LED lamp plate and circuit board and optic fibre buncher, optic fibre buncher is from outside assembly to the housing, other parts are located within the housing, a serial communication port, the LED lamp plate contains the lamp pearl that can the independent control more than 4 or 4, the lamp pearl evenly distributed on the lamp plate, the whole optical fiber coupling face that the area covered optic fibre buncher shines, set up anti-light wall between lamp plate and the optical fiber coupling face, anti-light wall marks off the scope of illuminating of each other that the area is roughly equal for every lamp pearl on the optical fiber coupling face.

Furthermore, one end of the reflecting wall is in contact with the lamp panel, and the other end of the reflecting wall reaches the optical fiber coupling surface of the optical fiber buncher.

Furthermore, the outside of reflection of light wall have radiating fin, the lamp plate assembles on the reflection of light wall.

Furthermore, the reflective wall is made of aluminum profiles.

Furthermore, the optical fiber buncher comprises an optical fiber assembling pipe and a shell connecting piece, an avoiding rib plate corresponding to the position of the light reflecting wall on the lamp panel is arranged in the optical fiber assembling pipe, and the shell connecting piece connects the optical fiber assembling pipe to the shell.

Further, the light reflecting wall and the optical fiber assembling pipe are made of the same profile.

Furthermore, the reflecting wall and the optical fiber assembly pipe are provided with positioning convex ribs or grooves, and the shell connecting piece is provided with a structure corresponding to the convex ribs or grooves.

Furthermore, reflection of light wall and optic fibre assembly pipe are the integrative section bar of not breaking, and on the lamp plate assembled reflection of light wall, the part that optic fibre assembly pipe exposes outside is equipped with radiating fin.

Furthermore, 7 lamp pearls are, and one is located the center, and other 6 evenly distributed are around it, and the outline of reflecting wall is circular, and inside is divided into 7 areas that are roughly equal, and every area has a lamp pearl to be located the center.

Furthermore, the number of the lamp beads is 9, the lamp beads are neatly arranged into 3 rows and 3 columns, the outline of the light reflecting wall is square, the interior of the light reflecting wall is divided into 9 square areas, and each area is provided with one lamp bead positioned in the center.

Generally speaking, the starry sky ceiling mainly includes optic fibre and ray apparatus except containing the ceiling body, and the ray apparatus mainly includes casing, circuit board, lamp plate, optic fibre buncher, and optic fibre buncher contains casing connecting piece and optic fibre assembly pipe, and the casing connecting piece is connected to the casing on the optic fibre assembly pipe, and optic fibre assembles in the optic fibre assembly pipe, and the one side optic fibre that is close to the lamp plate is pruned into the plane, is called the optical fiber coupling face as the input face of light.

As described in the background, blinking is a very striking function, and motor-driven shutters must be used in the light engine to achieve blinking. The rotation of the flap presents a potential hazard and is undesirable in the automotive industry.

For the scheme of realizing the scintillation through the separation blade, the scheme of this application passes through circuit board control part lamp pearl light and shade change, makes the light-emitting end of its corresponding optic fibre take place light and shade change to realize the scintillation effect, cancelled the moving part, improved the reliability of system greatly.

To achieve this goal, the fibers must be divided into many groups, each group forming a small bundle, occupying a region in which a bead must be located approximately in the center of the region to achieve uniform brightness, and the region should be as close to circular as possible to avoid long narrow shapes. Therefore, the lamp beads should be evenly distributed on the lamp panel.

In order to prevent the mutual interference between the lamp beads, the light rays of the lamp beads need to be isolated, so that the reflecting wall is necessary. In addition, the light reflecting wall can improve the utilization efficiency of light and increase the brightness.

When the number of the lamp beads is too small, the proportion of the optical fibers corresponding to each lamp bead is too high, the adjustment freedom is small, the effect is not good, and therefore the number of the optical fibers is at least 4.

The LED lamp beads can be single-chip white light lamp beads, RGB three-chip lamp beads and RGBW four-chip lamp beads.

The reflective wall must have a certain height to be effective, and preferably reaches the optical fiber coupling surface to prevent light from crossing the boundary and avoid the mutual influence of adjacent independently controlled illumination areas. Limited by the luminous angle of lamp pearl, the position that is close to the lamp plate does not have direct light almost, but in order to realize the connection between the part, the bottom and the lamp plate contact of reflection of light wall are better scheme.

Certainly, the lamp panel and the reflective wall are contacted with each other and then the radiating effect of the lamp panel is improved. This effect is even more pronounced when the reflector wall is externally provided with heat sinks. At this time, the volume of the reflective wall is generally large, and the lamp panel is preferably assembled on the reflective wall.

The aluminum profile, more commonly the aluminum alloy profile, the reflectivity is high, and the cross section shape is stable, cuts into the section, is the ideal choice of reflection of light wall.

The reflecting wall is made to be the height of the optical fiber coupling surface, which is enough to prevent the light rays of the adjacent light-emitting areas from interfering with each other. However, when the thickness of the reflective wall is too large, it is easy to cause the optical fiber to be blocked by the wall thickness, resulting in that the brightness of some light spots is always low. Therefore, in order to avoid this situation, the optical fiber assembly tube should also be provided with an internal structure corresponding to the reflective wall, i.e., an avoiding rib plate, so that the optical fibers avoid the corresponding position of the reflective wall, and each optical fiber is ensured to be within the irradiation range of a certain LED lamp bead.

When the reflective wall and the optical fiber assembly tube are both provided with internal partitions, it is considered to use the same profile as the reflective wall and the optical fiber assembly tube, but the reflective wall and the optical fiber assembly tube may have different cutting lengths and even require different subsequent processing.

In order to solve the problem that the reflective wall and the inner partition of the optical fiber assembly pipe correspond to each other, it is a good choice to provide a positioning rib or a groove on the outer part of the profile, especially when the outer profile is circular. The housing connector is provided with formations corresponding to the ribs or grooves, both of which cooperate with the connector, alignment of the two being readily achieved by means of the locating ribs or grooves.

The reflecting wall and the optical fiber assembling pipe are originally made of the same section bar, if the reflecting wall and the optical fiber assembling pipe are made of an unbroken integral material, the heat transfer is more facilitated, the advantage that most of the volume of the optical fiber assembling pipe is outside the shell can be utilized, heat in the shell is conducted outside the shell to dissipate the heat, and the heat dissipation efficiency can be greatly improved. At this time, the lamp plate must be assembled on the reflection of light wall, improves heat transfer efficiency through in close contact with. And the fiber assembly pipe exposes the afterbody outside the casing, sets up the fin, is favorable to improving the radiating efficiency more, reduces the temperature in the casing, prolongs the life of lamp pearl.

The arrangement of the lamp beads has the advantages that a preferable scheme is that a circle is divided into 7 relatively uniform areas, one area is arranged in the middle, and 6 areas are arranged on the periphery. The outer contour may still be circular, the inner contour may be a circle plus a ring divided into six segments, or a hexagon plus the remainder divided equally into 6 pieces.

Another preferred embodiment is a square with a 3 x 3 arrangement, the outer contour also being square. The arrangement is neat and the alignment is convenient. Relatively, the 2 × 2 arrangement of optical fibers has too few groups, the 4 × 4 arrangement is slightly more complex, and the 3 × 3 arrangement is a compromise solution.

In a conventional optical machine, optical fiber coupling surfaces are circular, so that an optical fiber bundle is wound or bundled by an electrical adhesive tape, is substantially circular, and is then assembled to an optical fiber assembly pipe. With a square cross-section fiber assembly tube, the fiber bundle cannot be pre-wound or bundled because such an operation would cause the fiber bundle to approach a round shape and would not fill the fiber assembly tube. In the scheme of the application, even if the overall outline of the optical fiber coupling surface is circular, the optical fiber bundle cannot be processed in advance by winding or bundling an electrical tape because the middle is divided into a plurality of areas by the avoiding rib plate, and the areas are almost not circular. One proposed method is to place the optical fibers in separate areas of the fiber assembly tube, and if there is more space, to continue to place the short optical fibers, and after the optical fibers are substantially filled, to squeeze the small wedge-shaped parts into the fiber assembly tube, so that the optical fibers are pressed against each other to prevent the optical fibers from moving or falling off.

This kind of mode through controlling a plurality of lamp pearls and changing luminance alone both can realize twinkling, also can all give out light, and when some lamp pearls were luminous not, the electric energy of consumption can reduce moreover, and the heat of production also can reduce. For the optical machine of the light blocking sheet scheme, the realization of the flicker is easy, but no matter at any moment, part of the optical fibers can be shielded by the light blocking sheet, so that all the light spots can not be simultaneously and completely lightened. On the other hand, when some optical fibers are blocked, the light emission of the lamp beads is not changed, the consumed electric energy is not reduced, and the service life of the optical machine is not favorable.

In the scheme of the application, the quantity of the lamp beads participating in the flashing can be controlled, so that richer changes are realized, for example, all the lamp beads are participated, and the flashing effect is good if a certain phase difference exists; and only a small part of lamp beads can participate in flickering, so that the lamp beads are closer to a real starry sky. This variation is not possible with conventional barrier solutions.

Therefore, the proposal of the application not only solves the problems of low reliability and low moving parts in the scintillation light machine, but also solves the problems of large volume of the light machine for indoor decoration, and also has the advantages of energy-saving effect, more abundant change and larger design freedom, so that the proposal is not problematic for indoor decoration besides being used for automobile interior decoration.

Detailed Description

Example 1

As shown in fig. 3, the optical engine includes a lamp panel 1 and an optical fiber bundling device 2, and a circuit board and a housing not shown in the figure. The lamp panel 1 is provided with a lamp bead 11, the optical fiber buncher 2 includes an optical fiber assembling pipe 21, the optical fiber 3 is assembled in the optical fiber assembling pipe 21, and the optical fiber 3 is trimmed to a regular plane at the front end of the optical fiber assembling pipe 21 and is called an optical fiber coupling plane as a light input plane. Be equipped with reflection of light wall 12 between the optical fiber coupling face of lamp plate 1 and optical fiber buncher, reflection of light wall 12 bottom and lamp plate 1 contact, the top reaches the optical fiber coupling face. The lamp pearl on the lamp plate is separated to the reflection of light wall, divides into individual solitary illumination zone to the fiber coupling face, prevents to interfere with each other, so the optical fiber luminance that every lamp pearl corresponds can independent control. When the brightness of one lamp bead is controlled to be gradually reduced and then gradually restored, the brightness of the optical fiber in the area corresponding to the lamp bead is correspondingly changed, and finally the effect of eye blinking, namely flickering, is generated in the corresponding light spot.

In order to prevent the reflective wall located inside from blocking part of the optical fibers, an escape rib 22 is also provided on the optical fiber mounting pipe 21 at a position corresponding to the reflective wall in the middle, so that the optical fibers mounted therein are kept away from the reflective wall.

As shown in fig. 4, the lamp plate is circular, arranges 7 RGBW four-chip lamp pearls on the lamp plate, and one of them is in the center, and 6 are around evenly distributed. The outer contour of the light reflecting wall is circular, the contour of the middle part of the light reflecting wall is hexagonal, the light reflecting wall further comprises a radial contour which is connected with the outer contour from the vertex of the hexagon, 7 approximately equal areas of atmosphere on the lamp panel are arranged on the whole contour, and each lamp bead is located in the approximately central position of each area. Outside the outline of reflecting light wall, be equipped with 3 groups of location bead, evenly distributed is in the periphery of reflecting light wall, and every group of reflecting light wall is two, except can playing the effect of location, lets the interior profile of reflecting light wall corresponding with the interior profile (dodging the gusset) of optic fibre assembly pipe, can also be used for realizing the screw fastening, for example assemble the reflecting light wall to the lamp plate on, perhaps assemble the lamp plate to the reflecting light wall on.

Compared with the traditional optical fiber assembly pipe, the assembly pipe has the advantages that each assembly space is filled with optical fibers as much as possible, when the number of the optical fibers is small, part of short optical fibers are inserted, and after the short optical fibers are difficult to insert, the wedge-shaped tensioning pieces can be continuously inserted, so that the optical fibers are firmly assembled and are not easy to loosen. Even a small amount of silica gel can be coated on the optical fibers, and the silica gel is used for realizing the bonding between the optical fibers and the tube wall of the section bar.

Example 2

As shown in fig. 5, 7 lamp beads are uniformly distributed on the circular lamp panel, one bead is positioned in the middle, and 6 beads are uniformly distributed around the lamp panel. The reflecting wall divides the lamp bead into independent lighting areas and is externally provided with radiating fins. The size of the lamp panel is larger than the circular outline of the reflecting wall, and the lamp panel is assembled on the fins of the reflecting wall through three screws.

The assembly of the reflective wall to the housing may also be by means of fins, through holes in the housing, with screws screwed from the outside, to snap onto the fins.

The heat that the lamp pearl produced on the one hand conducts on the radiating fin of reflecting the light wall through the lamp plate, and on the other hand air in the reflecting wall scope conducts the heat on the radiating fin through reflecting the light wall to realize better radiating effect.

Example 3

As shown in fig. 6, the lamp panel is square, and three rows and three columns of 9 four-chip lamp beads are regularly arranged on the lamp panel. The outer contour of the reflecting wall is square, and 9 lamp beads are separated into 9 mutually independent areas by the two vertical and horizontal reflecting walls. Therefore, the brightness and the color of each lamp bead only affect the corresponding optical fiber, and the flicker effect is easily realized by controlling a single lamp bead.

Corresponding to the reflecting wall, the same section bar can be adopted to manufacture the optical fiber assembling pipe, and the optical fiber assembling pipe is assembled on the shell through the shell connecting piece. Unlike round reflective walls and fiber mounting tubing, square profiles are easily aligned so no ridges or grooves are required. The square outer profile limits the rotation and makes the assembly easier.

Example 4

In view of the substantial conformity of the shapes and sizes of the light reflecting wall and the optical fiber installation pipe, it is a matter of course to adopt the same profile for the light reflecting wall and the optical fiber installation pipe.

A better scheme is that the reflecting wall and the optical fiber assembling tube are integrated, cutting is not needed, the number of parts is reduced, and the assembly of the reflecting wall and the shell is simpler.

One problem in this is the formation of fiber coupling surfaces. In general, when a separate structure is adopted, after an optical fiber is assembled in an optical fiber assembly pipe, the optical fiber having a length exceeding the optical fiber assembly pipe is cut and repaired to be flat, and an optical fiber coupling surface can be formed. When an integrated structure is adopted, the optical fiber coupling surface is positioned in the section bar, so that the optical fiber is pushed to the front end surface of the section bar to extend out for a section of length, the optical fiber at the rear end of the section bar is preliminarily fixed, then the optical fiber exceeding the front end surface is cut and flattened, finally the optical fiber is drawn backwards to reach a proper position, and the optical fiber is fixed from the rear end of the section bar to form the optical fiber coupling surface.

Here, the number of optical fibers corresponding to each lamp bead is relatively small, so a light condensing system provided by the lamp bead is adopted, light homogenization is realized through a reflecting wall, or the surface of the lamp bead is not provided with the light condensing system, and light homogenization is realized directly through the reflecting wall, so that the position of an optical fiber coupling surface does not need to be particularly accurate, and the optical fiber coupling surface can be formed through the mode of cutting, flattening and drawing back the optical fibers.

In this way the positional accuracy of the profile relative to the housing is less demanding. After the lamp panel is assembled on the section bar (the reflective wall), the signal line and the power line between the lamp panel and the circuit board are ensured to be connected without problems.

Owing to be integrative section bar, the heat that lamp pearl on the lamp plate produced can be conducted outside the casing along the section bar to improve the radiating effect. In order to further improve the heat dissipation effect, it is also a good choice to arrange heat dissipation fins at the tail of the profile. Therefore, the section bar is provided with fins, and the fins can be machined and removed by the part needing to be assembled with the shell or the shell connecting piece in the middle; the fins reserved outside the shell are completely reserved for heat dissipation; most fins are machined and removed by the section bar inside the shell, and only a small part of the section bar is reserved for fixing the lamp panel to the section bar. The machining removal here, which is to be done first, reduces the radial dimensions, but the dimensions are too large and can be difficult to accommodate in the housing. In addition, the number of the fins can be reduced, the fins are distributed on the whole circumference originally, only 2-4 groups of two fins in each group are reserved, and the fins are used for engaging screws when being assembled with the lamp panel; or more may be left for assembly with the housing or housing connector.

For the structure that the fins are arranged at the two ends (the outer end of the shell is provided with the complete fins, and the large part of the inner end of the shell is removed through processing to reserve a little) and the fins are completely removed from the middle section, the assembly of the section bar and the shell is more convenient, the section bar can be assembled on the shell or a shell connecting piece from one end of the light reflecting wall, and then the subsequent assembly is carried out.

The integrated structure improves heat dissipation and assembly, and is a remarkable improvement on the existing optical machine.
