Description

Technical Field

[0001] The utility model relates to the technical field of automobile side marker lamps, in particular to a novel luminous structure of a side marker lamp. Background Art

[0002] In the field of vehicle lighting, side marker lights are used as position lights and signal lights to play a marking role. With the evolution of the market, customers have higher and higher requirements for side marker lights, and the pursuit of functional diversification and styling innovation has also become a trend.

[0003] At present, the side marker lights in the existing technology are generally divided into separate lamps installed on the body, or integrated with the taillights. With the continuous development of science and technology, human-computer interaction functions have received more and more attention, and the car start-stop welcome function is an important part of it. However, the current optical solution cannot achieve the flowing water lighting function. The flowing water lighting lamp forms a dynamic lighting animation, which is very popular with the public. The solutions on the market are all in the form of light-emitting panels. When one LED is lit, the surrounding area will also light up. Therefore, it is impossible to make the side marker lights cooperate with other functions to achieve the flowing water lighting effect.

[0004] Moreover, the current optical solution has low light efficiency. The solutions on the market are all in the form of light-emitting panels, which requires densely distributed LEDs and scattering materials to light up the entire panel. A large number of LEDs are used, which is costly. In addition, the current optical solution has high requirements for space. The market adopts the direct LED solution. The LED needs to be a certain distance away from the light-emitting surface, otherwise it will cause bright spots and uneven light emission. However, this space is very wasteful for the side marker lights. There is rarely room to implement this solution in the narrow sheet metal space. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a novel side marker lamp luminous structure, which can achieve the effect of flowing water lighting, realize the function of the side marker lamp with a small amount of LED light source, and reduce the internal space of the lamp.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] A novel side marker light emitting structure comprises a bracket, a decorative ring clamped on the outer side of the bracket, a light guide structure arranged in the bracket and a circuit board;

[0008] The decorative ring includes a light-blocking portion and multiple rows of light-emitting portions distributed at intervals;

[0009] The light guide structure comprises a connecting member and a plurality of light conductors arranged in the middle of the connecting member, and the plurality of light conductors correspond to the plurality of rows of light emitting parts one by one;

[0010] The circuit board is arranged at one end of the light guide structure, and the circuit board has a plurality of LED light sources corresponding to the light guide body;

[0011] The light emitted by each LED light source can directly enter the corresponding light conductor, and the light conductor emits the light to the decorative ring, and then diffuses and emits the light through the corresponding light-emitting part.

[0012] Furthermore, light guide teeth are formed on the back side of the light conductor away from the decorative ring.

[0013] Furthermore, diffusion stripes are formed on the surface of the light conductor close to the decorative ring.

[0014] Furthermore, the optical conductor is parallel to the light emitting portion.

[0015] Furthermore, the distance between the optical conductor and the light emitting portion is greater than 1 mm.

[0016] Furthermore, the circuit board and the light guide structure are welded by heat riveting.

[0017] Furthermore, the decorative ring is formed by two-color injection molding.

[0018] Furthermore, the light emitting part is made of a scattering material.

[0019] Furthermore, the connecting piece and the plurality of optical conductors are integrally injection molded.

[0020] By adopting the above technical solution, the utility model has the following beneficial effects:

[0021] 1. The decorative ring of the utility model is designed with a light-blocking part and multiple rows of light-emitting parts distributed at intervals. The light-guiding structural member forms a one-to-one correspondence with the multiple rows of light-emitting parts through multiple light conductors, so that when the LED light source lights up the multiple light conductors, the layers are clear, and the light-blocking part can form a light-blocking effect. When the multiple rows of light-emitting parts emit light, they do not affect each other. The multiple LED light sources on the circuit board can light up the multiple light conductors in sequence, and circulate back and forth to achieve the effect of flowing lighting, achieving a dynamic visual effect of welcoming guests from the outside, and having more brand advantages.

[0022] 2. The utility model adopts the design of multiple light conductors and multiple rows of light-emitting parts. Only a corresponding number of LED light sources need to be installed at one end of the light conductor to achieve the effect of lighting up one by one. Therefore, a small number of LED light sources can be used to realize the function of the side marker light, saving the cost of the lamp.

[0023] 3. The utility model is designed with multiple optical conductors parallel to the light-emitting part, and the LED light source is set at the end of the optical conductor. The entire optical conductor is illuminated by direct light from the LED light source. The back of the optical conductor has optical teeth to form a refraction effect, and the surface of the optical conductor has diffusion stripes to improve uniformity. The distance between the optical conductor and the light-emitting part only needs to be greater than 1mm, thereby greatly reducing the space inside the lamp and ensuring the uniformity of light emission.

[0031] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0032] like Figure 1-6 As shown, in this embodiment, a new type of side marker lamp luminous structure is provided, which is mainly composed of a bracket 1, a decorative ring 2, a light guide structure 3, a circuit board 4 and other components. The decorative ring 2 is clamped on the outside of the bracket 1, and the light guide structure 3 and the circuit board 4 are both arranged in the bracket 1. The circuit board 4 and the light guide structure 3 are firmly welded by hot riveting. During assembly, the circuit board 4 can be welded to one end of the light guide structure 3 first, and then the light guide structure 3 is integrally installed in the bracket 1 to limit the position, and fixed by screws, and then the decorative ring 2 is clamped on the outside of the bracket 1 to form a sub-assembly. Of course, when the luminous structure of this embodiment is actually used, this sub-assembly must be installed in the vehicle lamp housing, fixed by screws, and finally assembled into an assembly lamp after the lampshade and the housing are welded.

[0033] Specifically, in order to achieve the dynamic effect of lighting up flowing water, the decorative ring 2 of this embodiment is composed of a light blocking portion 21 and five rows of light-emitting portions 22 distributed at intervals. The light blocking portion 21 is made of black opaque material, and the light-emitting portion 22 is made of milky red scattering material. The entire decorative ring 2 can be molded by two-color injection molding.

[0034] The light guide structure 3 is specifically composed of an outer connecting member 30 and five light conductors 31 arranged in the middle of the connecting member 30. The light guide structure 3 can be integrally injection molded by a mold, and after assembly, the five light conductors 31 correspond to the five rows of light emitting portions 22 one by one, and the surfaces of the five light conductors 31 are respectively opposite to and parallel to the five light emitting portions 22. In addition, the distance between each light conductor 31 and the corresponding light emitting portion 22 is greater than 1 mm to ensure normal light diffusion.

[0035] The circuit board 4 also has five LED light sources 40 corresponding to the light conductors 31. After the circuit board 4 is welded to one end of the light guide structure 3, the five LED light sources 40 are directly opposite to the light inlets at one end of the five light conductors 31. In this way, the light emitted by each LED light source 40 can directly enter the corresponding light conductor 31, and the light conductor 31 can emit the light to the decorative ring 2, and then diffuse and emit through the corresponding light-emitting part 22, and finally enter the human eye after being emitted through the lampshade to ensure a uniform optical effect. Since the five light conductors 31 are designed to be parallel to the light-emitting part 22, and the LED light source 40 is set at the end of the light conductor 31, the entire light conductor 31 is illuminated by the direct light of the LED light source 40, and the distance between the light conductor 31 and the light-emitting part 22 only needs to be greater than 1 mm, thereby greatly reducing the space inside the lamp.

[0036] In order to improve the uniformity of lighting, in this embodiment, the light conductor 31 is provided with light guide teeth 312 on the back side surface away from the decorative ring 2. The light guide teeth 312 can refract the light entering the light conductor 31. At the same time, diffusion stripes 311 are provided on the surface of the light conductor 31 close to the decorative ring 2. The refracted light will be evenly diffused and emitted through the diffusion stripes 311, and then hit the light-emitting portion 22 of the decorative ring 2 to ensure a uniform optical effect.

[0037] Through the above design, it can be seen that the decorative ring 2 of this embodiment is designed with the light blocking part 21 and the five rows of light emitting parts 22 distributed at intervals, and the light guide structure 3 forms a one-to-one correspondence with the five rows of light emitting parts 22 through the five light conductors 31, so that the LED light source 40 lights up the five light conductors 31 in a clear layer, and the light blocking effect can be formed by relying on the light blocking part 21. The five rows of light emitting parts 22 do not affect each other when they emit light. The five LED light sources 40 on the circuit board 4 can light up the five light conductors 31 in sequence, and cycle back and forth to achieve the effect of flowing water lighting, and achieve a dynamic visual effect of welcoming guests from the outside, which has more brand advantages. In addition, this embodiment only needs five LED light sources 40 to achieve the effect of one-to-one lighting, so a small number of LED light sources 40 can be used to achieve the function of the side marker light, saving the cost of the lamp.
