[0033] At present, automobile lamps are more and more inclined to the trend of integration, multi-function and small space occupation. The traditional automobile rear lamp includes brake lamp, position lamp, turn signal lamp, reversing lamp, rear fog lamp and return reflector, license plate lamp, etc. For combination lamp, there are brake lamp, position lamp, turn signal lamp, reversing lamp, however, to realize the integration of four lamps on one combination lamp, not only occupies large space, but also the design is complex. If simply arranged to realize the function, the corresponding defects will also be exposed, and the simple structure cannot realize the multi-functional combination, only 2 or 3 lamps can be simply combined and the light emission is uneven. The traditional rear combination lamp mostly uses halogen bulb, which occupies large space and has larger power, higher lamp cavity temperature, lower service life and more aging lamp body when working than LED, and the light emission mode is single and can only adopt direct emission. It is easy to cause uneven light emission on the light emission surface, obvious particle feeling and dazzling of lamp beads from the rear observation, which can cause glare and interference to pedestrians and rear vehicles.

[0034] The rear combination lamp using LED lamp beads mostly adopts direct emission, which is simple and rough and has low cost, but the space utilization rate is low and the internal structure of the lamp can be seen from the rear, the LED light source emits unevenly, which can cause particle feeling on the light emission surface and waste of LED light source light. Stray light and the like can cause night light pollution, and the particle feeling of the rear combination lamp is obvious, which can cause glare and interference to pedestrians and drivers of rear vehicles.

[0035] As the mainstream light source on the market, LED lamp beads have the advantages of small size, environmental protection and energy saving, long service life, and less influence of environmental factors, and have been widely used in automobile lamp manufacturing. However, the LED light source has the problems of uneven light emission, single light emission mode, non-ideal refracted light, and inability to control the light emission path, resulting in low light utilization rate of the LED light source.

[0036] The combination lamp using LED lamp beads on the market usually does not have light uniformity processing for cost saving and space saving, resulting in uneven light emission of the LED light source and particle feeling on the light emission surface, low light utilization rate of the LED light source, and interference to pedestrians and drivers of rear vehicles. The present application can improve the light emission uniformity of the LED light source, reduce the particle feeling on the light emission surface, improve the light utilization rate, and avoid interference to pedestrians and drivers of rear vehicles.

[0054] Specifically, the decorative frame 7 is provided with four extension positioning ribs corresponding to the regions of the thick-walled part 4 of the turn signal lamp and the thick-walled part 5 of the brake lamp, the ribs are directly clamped into the extension buckles on the side of the thick-walled part 4 of the turn signal lamp and the thick-walled part 5 of the brake lamp to fix the decorative frame 7 in the region, and an extension mounting hole is further arranged at the upper and lower ends of the region of the thick-walled part 4 of the turn signal lamp and the thick-walled part 5 of the brake lamp, which is concentric with the mounting holes at the upper and lower ends of the thick-walled part 4 of the turn signal lamp and the thick-walled part 5 of the brake lamp and the boss column of the base 3. After the screws are fixed, the decorative frame 7, the thick-walled part 4 of the turn signal lamp, the thick-walled part 5 of the brake lamp and the base 3 can be connected and fixed. The decorative frame 7 is provided with an extension rib on the edge of the region corresponding to the first position lamp light-emitting unit 301 and the second position lamp light-emitting unit, which is in close contact with the inner wall of the lamp shell 1 during installation, and can play a limiting and fixing role. The edge of the region corresponding to the reversing lamp light-emitting unit 304 of the decorative frame 7 is provided with an extension buckle, which cooperates with the extension rib of the inner light distribution lens 601 of the reversing lamp. During installation, the extension rib of the inner light distribution lens 601 of the reversing lamp is clamped into the buckle of the decorative frame 7 to be connected and fixed. The decorative frame 7, the thick-walled part 5 of the brake lamp, the thick-walled part 4 of the turn signal lamp, the inner light distribution lens 601 of the reversing lamp and the base 3 are connected and fixed through the buckles, extension ribs and mounting holes of the above-mentioned regions. Specifically, the decorative frame 7 can be made of black PC material, and light-blocking walls with different heights and thicknesses are arranged between the first position lamp light-emitting unit 301 and the turn signal lamp light-emitting unit 302 and between the second position lamp light-emitting unit and the brake lamp light-emitting unit, so that the light emitted by them does not interfere with each other.

[0055] In a possible implementation, the inner light distribution lens 602 of the position lamp is provided with a diffusion agent inside for uniformly mixing and emitting light. The diffusion agent can be a microsphere product generated by cross-linking and grafting functional groups through high molecular polymerization technology, which can increase the scattering and transmission of light, and can make the entire resin emit softer light and achieve light transmission without opacity while hiding the light source and dazzling light source.

[0056] In a possible implementation, the outer light distribution lens housing 2 is provided with a light distribution lens black edge 201 and a light distribution lens red edge 202 on both upper and lower sides, and a light distribution lens white edge 203 corresponding to the reversing lamp light emitting unit 304 is arranged in the middle of the outer light distribution lens housing 2.

[0057] Specifically, the outer light distribution lens housing 2 can be made of PMMA material, such as polymethyl methacrylate, which has excellent transparency and weather resistance. The light distribution lens black edge 201 has the effect of shielding the internal structure of the lamp and blocking stray light, avoiding defects such as exposure of the internal structure of the lamp and edge light leakage. The light distribution lens white edge 203 can be used for the reversing lamp light emitting unit 304 when emitting light. After the reversing lamp reflector 303 reflects and converts the light source and the inner light distribution lens 601 of the reversing lamp, the light source of the reversing lamp is uniformly refracted out through the light distribution lens white edge 203, expanding the illumination range of the light, and making the road surface lighting behind the vehicle more uniform. The light distribution lens red edge 202 has a light red transparent effect, which is used for light distribution and light emission of the turn signal light emitting unit 302, the brake light emitting unit and the position light emitting unit, and fully and uniformly refracts the light emitted by the above light emitting units.

[0058] In a possible implementation, the lamp housing 1 is fixedly connected with a breathable cap 8 for heat dissipation on both upper and lower sides, which can dissipate heat and balance the internal and external air pressure when the rear combination lamp is working. The lamp housing 1 is also provided with a wire harness assembly 9 and a wire harness connector fixing hole at the lower end, which can facilitate wire harness fixation and docking end wire harness installation.

[0059] In summary, the multifunctional rear combination lamp combines three light emission modes. The reversing lamp adopts LED side projection, reflector reflection, inner light distribution lens uniform light, and outer light distribution lens light emission mode to achieve uniform light emission effect. The position lamp adopts LED direct emission, inner light distribution lens uniform light, and outer light distribution lens light emission to achieve uniform light emission effect. The brake light and the turn signal light adopt LED direct emission, thick-walled light guide scattering, and outer light distribution lens light emission to achieve uniform light emission effect. The lamp combines the functions of reversing lamp (white), position lamp (red), turn signal light (amber), and brake light (red), and all four functions can emit light uniformly, forming a variety of combined light emission forms.
