Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically to vehicle brake lights, and more particularly to a brake light with projection function. Background Technology

[0002] With the increasing popularity of automobiles, people have higher and higher demands for the driving experience. Currently, automotive lights are not merely illumination or signaling devices; many lights can reflect the car's design language and highlight its family design. High-mounted brake lights are generally installed at the upper rear of the vehicle to make it easier for following vehicles to see the vehicle braking in front, thus preventing rear-end collisions. However, traditional high-mounted brake lights only serve a braking signal function and do not reflect the car's design language.

[0003] Patent CN119947927A discloses a vehicle light-emitting device configured to perform the function of a high-mounted brake light, including a main optical module and an auxiliary optical module. The main optical module realizes the function of illuminating the high-mounted brake light, and the auxiliary optical module realizes the projection function. This optical system requires two PCB boards, and its internal structure is complex, with many components and high cost. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the technical problem of complex structure and many parts in the existing optical system, this utility model provides a braking lamp with projection function, which integrates the projection light source and the braking light source on the same side of the PCB board, reduces the number of PCB boards, and uses direct and reflective optical schemes to achieve the projection lighting effect and the braking lighting effect respectively.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a braking lamp with projection function, comprising: a lampshade; a PCB board located inside the lampshade, wherein a projection light source and a braking light source are spaced apart on one side of the PCB board; an inner lampshade located in the light emission direction of the projection light source, wherein the light from the projection light source passes through the inner lampshade and is emitted from the lampshade; and a first reflector disposed on the PCB board, wherein the first reflector is disposed between the projection light source and the braking light source and extends in the light emission direction of the braking light source, wherein the light from the braking light source passes through the reflector and is emitted from the lampshade.

[0006] This utility model features a brake light with projection function. By placing the projection light source and the brake light source on the same PCB board, the number of PCB boards is reduced. The inner lamp cover and the first reflector are used to create projection lighting effect and brake lighting effect with different light output directions for the projection light source and the brake light source emitting light from the same side, respectively, thereby optimizing the optical system.

[0007] Furthermore, in order to further optimize the optical system, the projection light source and the braking light source have the same light emission direction.

[0008] Furthermore, in order to form a projected light-emitting area and a braked light-emitting area, the lampshade has a first light-transmitting area and a second light-transmitting area. The first light-transmitting area is located on the outer side of the first reflector, and the second light-transmitting area is located on the lower side of the inner lampshade.

[0009] Furthermore, to avoid interference between the projection lighting effect and the braking lighting effect, all areas of the lampshade except for the first and second light-transmitting areas are non-light-transmitting areas.

[0010] Furthermore, the first light-transmitting area, the second light-transmitting area, and the non-light-transmitting area are formed into a lampshade through two-color injection molding, and the lampshade is fixedly connected to the housing. Thus, a lampshade and a housing are produced.

[0011] Furthermore, in order to optimize the projection effect, a second reflector is provided on the PCB board. The second reflector is located to the left of the projection light source, and the surfaces of the first and second reflectors facing the projection light source form a focusing area relative to the projection light source.

[0012] Furthermore, in order to ensure the braking and lighting effect, both the first and second reflectors are parabolic reflectors.

[0013] Furthermore, to simplify the lamp assembly structure, the first and second reflectors are connected to the PCB board.

[0014] Furthermore, in order to create different projection visual effects, the surface of the inner lampshade has projection patterns or projection designs.

[0015] Furthermore, to simplify the assembly of the inner lampshade, the left and right ends of the inner lampshade are respectively connected to the lower ends of the first reflector and the second reflector.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is a braking lamp with projection function. It integrates the projection light source and the braking light source on a single PCB board, reducing the number of PCBs, simplifying the lamp structure, and reducing costs. At the same time, it uses the inner lamp cover and the first reflector to realize the emission of light from the projection light source and the braking light source, achieving projection lighting effect and braking lighting effect at different positions, thus optimizing the optical system.

[0017] 2. The present invention is a brake lamp with projection function. It uses the first and second reflectors on both sides of the projection light source to form a focusing effect, which makes the projection lighting effect better.

[0018] 3. The present invention provides a brake light with projection function, which clearly separates the projected light and the brake light by using a first light-transmitting area, a second light-transmitting area and a non-light-transmitting area on the lampshade, so as to avoid mutual interference between the two and improve the lighting effect.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1, as Figures 1 to 2As shown, a brake light with projection function includes: a lampshade 1 and a housing 8, wherein the lampshade 1 and the housing are fixedly connected by welding to form a space for installing the lamp.

[0026] Specifically, PCB board 2 is disposed inside lampshade 1. A projection light source 3 and a braking light source 4 are spaced apart on one side of PCB board 2. In this embodiment, the projection light source 3 and the braking light source 4 are disposed on the lower side of PCB board 2, and the light emission direction of both the projection light source 3 and the braking light source 4 is downward. In this embodiment, the projection light source 3 and the braking light source 4 are disposed on the same PCB board 2. Specifically, a first reflector 5 is provided on the PCB board 2. The first reflector 5 is located between the projection light source 3 and the braking light source 4, and extends in the light emission direction of the braking light source 4. The light from the braking light source 4 passes through the reflector and is emitted from the lampshade 1, with the light propagation direction as follows: Figure 2 As shown by arrow a, the light from the brake light source 4 shines downwards onto the first reflector 5. After being reflected by the first reflector 5, the light exits from the lamp cover 1 in a horizontal direction, creating the brake light illumination effect. The direction of light propagation is as follows: Figure 2 As indicated by arrow b.

[0027] Preferably, the first reflector 5 is a parabolic reflector. The first reflector 5 is fixed to the PCB board 2 by snap-fitting, welding, or riveting.

[0028] Specifically, the inner lampshade 6 is located in the light-emitting direction of the projection light source 3. The light from the projection light source 3 passes through the inner lampshade 6 and then exits from the lampshade 1. The light from the projection light source 3 passes downward through the inner lampshade 6 and the lampshade 1 in sequence, thus forming a projection lighting effect below. The projection light source 3 and the braking light source 4 are separated by the first reflector 5, so that the light from the braking light source 4 is emitted horizontally, while the light from the projection light source 3 is emitted directly downward, and the two do not interfere with each other.

[0029] Specifically, the lampshade 1 has a first light-transmitting area 11 and a second light-transmitting area 12. The first light-transmitting area 11 is located on the outer side of the first reflector 5, and the second light-transmitting area 12 is located on the lower side of the inner lampshade 6. The position of the first light-transmitting area 11 corresponds to the reflector, and the braking light is emitted directly through the first light-transmitting area 11. The second light-transmitting area 12 corresponds to the inner lampshade 6, and the projected light is emitted directly through the second light-transmitting area 12. The two do not affect each other.

[0030] Preferably, the area of ​​the lampshade 1 other than the first light-transmitting area 11 and the second light-transmitting area 12 is a non-light-transmitting area. The first light-transmitting area 11, the second light-transmitting area 12, and the non-light-transmitting area are formed into the lampshade 1 by two-color injection molding. The non-light-transmitting area is generally black, which can block the light and avoid the interference between the light from the projection and the braking.

[0031] In Embodiment Two, based on Embodiment One, a second reflector 7 is provided on the PCB board 2. The second reflector 7 is located to the left of the projection light source 3, and the surfaces of the first reflector 5 and the second reflector 7 facing the projection light source 3 form a focusing area relative to the projection light source 3. The first reflector 5 and the second reflector 7 are symmetrically arranged. Under the obstruction of the first reflector 5 and the second reflector 7, the light from the projection light source 3 will converge between the first reflector 5 and the second reflector 7, making the projection effect brighter.

[0032] Preferably, the second reflector 7 is a parabolic reflector. The second reflector 7 is fixed to the PCB board 2 by snap-fitting, welding, or riveting.

[0033] Preferably, the left and right ends of the inner lamp cover 6 are connected to the lower ends of the first reflector 5 and the second reflector 7, respectively, so that the inner lamp cover 6 can be quickly assembled.

[0034] In Example 3, based on Example 2, the surface of the inner lampshade 6 has a projection pattern or projection design, which can project a specific pattern.

[0035] In summary, the present invention provides a braking lamp with projection function. By placing the projection light source and the braking light source on the same PCB board, the number of PCB boards is reduced. The inner lamp cover and the first reflector are used to form projection lighting effect and braking lighting effect with different light output directions for the projection light source and the braking light source emitting light from the same side, respectively, thereby optimizing the optical system.

[0036] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
