[0032] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0034] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0035] This utility model provides a trunk light and a vehicle employing it, which can be applied in the field of lighting, such as lighting a vehicle trunk. This utility model's trunk light can deflect direct light to the bottom of the trunk without requiring excessive rotation, ensuring that the illuminated area meets the trunk's lighting requirements. A detailed description is provided below using specific embodiments.

[0036] See Figures 1 to 4 In one embodiment of the present invention, a trunk light 10 is provided. Figure 1 As shown, after the light emitted by the trunk light 10 is deflected, the deflected light 30 can illuminate the bottom of the trunk of the vehicle body 20. Therefore, when the user opens the trunk lid of the vehicle body 20, the trunk light 20 in the trunk automatically illuminates the bottom of the trunk, allowing the user to clearly see the objects at the bottom of the trunk and conveniently take them out. Figure 2 、 Figure 3 and Figure 4 As shown, Figure 2 This is a schematic diagram of the appearance of the trunk light. Figure 3 This is a cross-sectional view of the trunk lamp. Figure 4 This is a cross-sectional view of a trunk light provided by one embodiment of the present invention. For example, the trunk light 10 may include a rear cover 110, a light source circuit board 120, a deflecting lens 130, and a lampshade 140. The rear cover 110 serves as the mounting base for the trunk light 10. The light source circuit board 120 and the deflecting lens 130 may be mounted on the rear cover 110. The rear cover 110 and the lampshade 140, when connected, form the outer shell of the trunk light 10. The trunk light 10 illuminates when the trunk door is opened. The rear cover 110 may be mounted on the side wall of a trunk to illuminate the space within. The light source circuit board 120 may be connected to the rear cover 110, and multiple lamps may be mounted on one light source circuit board 120, allowing the multiple lamps to simultaneously illuminate the trunk space. The deflecting lens 130 may be located on the side of the light source circuit board 120 away from the rear cover. The deflecting lens 130 deflects the light from the lamp so that the deflected light 30 illuminates the bottom of the trunk.

[0037] See Figures 1 to 4In one embodiment of the present invention, within the trunk light 10, the light source circuit board 120 may be a printed circuit board (PCB). The light source circuit board 120 may be formed as follows: After the PCB is designed and manufactured (PCBA, Printed Circuit Board Assembly), various electronic components, integrated circuits, resistors, capacitors, connectors, etc., are mounted on the PCB (Printed Circuit Board) using assembly processes such as surface mount technology (SMT) or through-hole insertion (DIP) technology, and then soldered. In an optical system, a deflection lens 130 is often used to adjust the light path or change the direction of a light beam. Deflection is achieved by using the principles of reflection or refraction, and may be implemented using, for example, a free-form surface lens, a prism assembly, or a microlens array. In light-emitting diode (LED) lighting, the deflection lens 130 can achieve a specific angle of beam distribution. The deflection lens 130 deflects the light beam emitted by the LED light source and transforms the originally nearly uniformly divergent light beam into a light beam with a specific directionality. Figure 1 As shown, the rear cover 110 is mounted on the side wall of the luggage box, and the lighting lamp on the light source circuit board 120 emits horizontal direct light. After passing through the deflection effect of the deflection lens 130, the direct light becomes a deflected light 30 inclined downward. The deflected light 30 is irradiated to the bottom of the luggage box, wherein the deflection angle of the deflection lens 130 to the light direction of the lighting lamp can be 30° to 60°.

[0038] See Figure 3 、 Figure 4 and Figure 5 In one embodiment of the present invention, there may be multiple deflecting lenses 130, and one deflecting lens 130 may correspond to one lighting lamp, that is, one deflecting lens 130 may be used to deflect the direct light of one lighting lamp so that the deflected light can illuminate the target area. Figure 3 and Figure 4 As shown, the back cover 110 may be provided with different placement slots 150, and a lighting lamp and the deflection lens 130 corresponding to the lighting lamp may be placed in the same placement slot 150. By placing different lighting lamps in different placement slots 150, the deflection of the lighting lamps by two adjacent deflection lenses 130 can be made independent of each other without affecting each other. Figure 3 and Figure 4As shown, two lamps are mounted on the light source circuit board 120, and two deflecting lenses 130 are provided accordingly. Each deflecting lens 130 can be used to deflect the direct light from one lamp. The deflecting lens 130 and the lamp housing 140 can be arranged in contact with each other, and a gap can exist between the deflecting lens 130 and the lamp on the light source circuit board 120 to ensure that the deflecting lens 130 can achieve the desired deflection angle for the light emitted by the lamp.

[0039] See Figures 6 to 9 In one embodiment of the present invention, optical teeth are provided on the surface of the deflecting lens 130 on the side away from the lighting lamp. The optical teeth are distributed periodically or non-periodically. External optical teeth are a microstructure that achieves functions such as light deflection and diffusion by etching a series of periodic or non-periodic microstructures on the surface of the deflecting lens 130. The size, spacing and depth of the optical teeth of the microstructure will directly affect the propagation path and phase distribution of the light. Figure 8 As shown, the optical teeth are in the shape of squares, and the square-shaped optical teeth are distributed periodically. The incident light field is modulated by a series of squares of the same size and spacing to achieve beam splitting, shaping, deflection and other effects. For example, adjacent squares are transparent (letting light pass through) and blocked (reflecting or absorbing) in turn to form a 0-1 phase modulation. Figure 9 As shown, the optical teeth are in a sawtooth shape, and the sawtooth-shaped optical teeth are distributed periodically. The angle and size changes of the sawtooth-shaped optical teeth can provide a continuous phase gradient, thereby guiding the light wave to propagate along a preset path. Compared with the square shape, the sawtooth-shaped structure can provide a more continuous and fine phase distribution, thereby achieving higher optical performance. Both square-shaped and sawtooth-shaped optical teeth can change the propagation direction of light, and due to the deflection effect, the incident light energy can be dispersed in a predetermined direction as needed. In the actual manufacturing process, this type of microstructured optical teeth are made on the surface of optical materials through precise semiconductor micromachining technology (such as electron beam exposure and etching technology).

[0040] See Figure 10In one embodiment of the present invention, a vehicle is provided, comprising a vehicle body 20 and a trunk light 10, which is mounted on the side wall of the trunk of the vehicle body 20. The trunk light 10 comprises a rear cover 110, a light source circuit board 120, a deflecting lens 130, and a lampshade 140. The connection, positional, and correspondence between the rear cover 110, the light source circuit board 120, the deflecting lens 130, and the lampshade 140 are consistent with the above description. The lamp on the light source circuit board 120 emits horizontal direct light. After being deflected by the deflecting lens 130, the direct light is transformed into deflected light 30 directed downward, which is then irradiated to the bottom of the trunk. Mounting the trunk light 10 on the vehicle body 20 deflects the direct light from the lamp in the vehicle trunk to the bottom of the trunk, ensuring that the illuminated area meets the lighting requirements of the trunk.

[0041] In summary, the present invention proposes a trunk light and a vehicle using the same. The trunk light can deflect the direct light of the lighting lamp to the bottom of the trunk without rotating too much, and has the advantages of simple structure, easy operation, and strong practicality.
