[0003] The current car starry sky ceiling usually refers to LED lighting. By punching holes in the ceiling and arranging optical fibers in the light-transmitting area, the optical fibers pass through the holes to transmit light to the perforated area of the ceiling. Optical fibers of different diameters are distributed in between, including super bright stars, bright stars, dim stars, and starry sky patterns. The starlight flickers, allowing different colors to appear alternately, or it can be located to a certain color. However, this lighting method requires manual fiber insertion, has low production capacity, poor product consistency, and a fixed light point with a limited number. The light-emitting level depends on the length and diameter of the optical fiber, and the 3D effect presented is not good. In addition, the demand for optical fibers is large, and it is impossible to light up a large area of starry sky patterns with a single light source, resulting in low utilization of a single light source and serious energy consumption.

DETAILED DESCRIPTION
[0017] Specific embodiment 1: Please refer to Figure 1-Figure 5 A starry sky top light source irradiation component comprises a light guide plate 1 arranged on the outer layer, wherein the light guide plate 1 is made of a light-transmitting material, and the light guide plate 1 has a certain light transmittance. A plurality of light-emitting points are provided on the upper end surface of the light guide plate 1. The plurality of light-emitting points are all provided on the light guide plate 1 by etching, and the plurality of light-emitting points have the function of illuminating through light. The end surface of the light guide plate 1 without the light-emitting points is not light-transmitting, and preferably the end surface of the light guide plate 1 without the light-emitting points is uniformly covered with a light-shielding diaphragm. The plurality of light-emitting points include a pattern groove 11, a star point groove 12 and a star groove 13, and the light-emitting points of different shapes mentioned above are used to form a night sky simulation pattern with a constellation figure.
[0018] The inner layer of the light guide plate 1 is provided with a light source cavity 14, and the end face of the light source cavity 14 away from the light-emitting point is provided with a light source 2, and the light-emitting direction of the light source 2 is provided toward the end face of multiple light-emitting points. A light guide bar 21 is provided between the light source 2 and the light-emitting point, so that light is input to the input end of the light guide bar 21 through the illumination of the light source 2. There is a certain distance between the light source 2 and the light guide bar 21, and the light source 2 is preferably an LED lamp, and the illumination range of the light source 2 is divergent, as shown in detail. Figure 4 , the distance between the light source 2 and the light guide bar 21 makes the divergence angle of the light source 2 overflow along the periphery of the light guide bar 21, so that part of the light overflowing from the light source 2 can be projected onto the light guide plate 1 to illuminate part of the light-emitting point. Figure 5 As shown, due to the distance between the light source 2 and the light guide bar 21 , the divergence range of the light source 2 is increased, so that a single light source 2 has the range of illuminating a large area of the pattern grooves 11 .
[0019] The light guide bar 21 is provided with a plurality of light guide extension bars 211 extending outward in multiple directions along one end away from the light source 2. A light guide output head 212 is provided at the end of each light guide extension bar 211, and the output end of each light guide output head 212 corresponds to a light emitting point, and the output end of each light guide output head 212 abuts against the corresponding light emitting point, so that the light guide output head 212 transmits light to the light emitting point. The light guide bar 21, the light guide extension bar 211 and the light guide output head 212 are made as one body, and are collectively referred to as a light guide. The light guide bar 21 is the input end of the light guide, the light guide extension bar 211 is the light transmission section of the light guide, and the light guide output head 212 is the output end of the light guide.
[0020] The light guide inner layer of the light guide member is partially provided with light teeth or is completely free of light teeth. Preferably, the light guide inner layer of the light guide member is completely free of light teeth to increase the diffusion of light by the light guide member in the path direction. Figure 6 As shown, the light guide has light diffusion and divergence in the path direction. When the light guide inner layer of the light guide is not provided with light teeth, the light guide itself has a certain diffuse reflection to overflow the light in the path direction of the light guide to achieve auxiliary illumination.
[0021] It should be noted that this solution has at least three light source divergence points: The first light source divergence point: there is a certain distance between the light source 2 and the light guide bar 21, and the distance generated by the distance causes the light source 2 itself to overflow along the periphery of the light guide bar 21, so that the projection area irradiated by the light source 2 from the near end to the far end is increased, and the light emission direction of the light source 2 is toward the light guide plate 1 to illuminate the pattern groove 11 and / or star point groove 12 and / or star groove 13 within the divergence range of the overflow of the light source 2.
[0022] Second light source divergence point: The light guide bar 21 absorbs the light from the light source 2, and then outputs the light through the multiple light guide extension bars 211 arranged in the path direction of the light guide bar 21, and finally outputs the light through the light guide output heads 212 arranged at the ends of the multiple light guide extension bars 211. The light guide output heads 212 of each light guide extension bar 211 are arranged corresponding to the corresponding star point slots 12 and / or star slots 13 to illuminate the star point slots 12 and / or star slots 13 within the output range of the light guide output heads 212.
[0023] The third light source divergence point: The third light source divergence point is used as an auxiliary light source for divergence, and the light guide inner layer of the light guide member is not provided with light teeth, so that the light guide member has light divergence in the path direction. The light diverged by the light guide member in the path direction illuminates the pattern groove 11 and / or the star point groove 12 and / or the star groove 13 within the divergence range of the light guide member in the path direction.
[0024] Working principle: When the present invention is in use, light is introduced into the light guide bar through a single light source at the lower end of the light guide plate. As the light enters the light guide bar, the light is extended peripherally through the light guide extension bars arranged in multiple path directions, and then the light is transmitted to the far end of the light source through the light guide output head. At the same time, a certain distance is set at the connection between the light source and the light guide bar, so that the projection area of the angle of divergence of the light source set relative to the light guide bar is increased. In addition, the light guide inner layer of the light guide extension bar is set to have no light teeth at all, so that the light guide extension bar also has the ability to diffusely reflect and diverge light in the range set in the path direction.
[0025] Specific embodiment 2: Different from specific embodiment 1, the light guide input and output ends are provided with a plurality of light teeth, that is, the light guide inner layer of the light guide bar 21 is provided with a plurality of light teeth arranged evenly, the light guide inner layer of the light guide output head 212 is provided with a plurality of light teeth arranged evenly, and the light guide inner layer of the light guide extension bar 211 is not provided with light teeth. The light teeth are used to adjust the brightness of the input and output ends of the light guide, and the brightness is adjusted by the width and spacing of the light teeth to achieve the transmission of light in the path direction. It should be noted that the light teeth of this embodiment are provided at the input and output ends of the light guide, so that the light is transmitted brighter at the positions of the input and output ends of the light guide and the stable transmission of the light path is maintained; and on the path of the light guide extension bar 211, since no light teeth are provided, the light can have the diffusion of light in multiple directions, and the light is diffusely reflected outward on the light transmission section path through the path of the light guide extension bar 211, and the diffusely reflected light is irradiated on multiple light-emitting points within the projection range.
[0026] Specific embodiment 3: Different from specific embodiment 1, the LED of the light source 2 is connected to a controller, and the light source 2 is electrically connected to the controller. The controller is used to control the working mode of the LED, including the adjustment of the flashing time and / or light color of the LED.
[0027] Specific embodiment 4: Different from specific embodiment 1, the light source cavity 14 of the light guide plate 1 further includes a plurality of light sources 2, and the light sources 2 are arranged equidistantly in the light source cavity 14. The light emission directions of the plurality of light sources 2 are arranged toward the end faces of the plurality of light-emitting points, a corresponding light guide is arranged between each light source 2 and each light-emitting point, and a certain gap is maintained between the plurality of light sources 2 and the corresponding light guide.
[0028] Specific embodiment 5: Different from the specific embodiment 1, a light guide extension strip 211 is provided outwardly at one end of the light guide strip 21 away from the light source 2. A light guide output head 212 is provided at the end of the light guide extension strip 211 away from the light guide strip 21, and the light guide output head 212 is provided corresponding to a light-emitting point, so that the light guide output head 212 outputs light to the corresponding light-emitting point. The light guide output head 212 is provided in contact with the corresponding light-emitting point. It should be noted that a single light guide output head 212 illuminates a single light-emitting point.
