TECHNICAL FIELD

[0001] The utility model belongs to the field of automobile side marker light, concretely relates to a side marker light optical structure which can emit light uniformly and has low cost. BACKGROUND

[0002] At present, the optical scheme of the automobile side marker light is difficult to simultaneously consider uniform light emission, regulations and low power at a relatively low cost because the space of the side marker light is shallow in the light emission direction, and only LED light source and light distribution mirror are used. If the total power of the LED light source is low and the light emission uniformity is good, a light guide member needs to be additionally added. If the light guide member is not added, the uniform light effect needs to be improved by adding a light distribution mirror with low transmittance, thereby increasing the total power of the LED light source. SUMMARY

[0003] To solve the above problems in the prior art, the utility model provides a side marker light optical structure which can emit light uniformly and has low cost. The light guide member is not added, and the improved light distribution mirror can ensure uniform light emission and low power of the light source.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a side marker light optical structure which can emit light uniformly and has low cost, comprising a lamp body and a light distribution mirror which is buckled with the outer peripheral end surface of the lamp body.

A protrusion one is arranged in the middle of the light distribution mirror. The protrusion one extends downward to below the outer periphery of the light distribution mirror. The lower part of the protrusion one is located in the cavity. A protrusion two is arranged in the middle of the upper surface of the light distribution mirror. The upper surface of the protrusion two is provided with a light emission surface. The light distribution mirror is integrally injection molded. A PCBA board is connected in the cavity of the lamp body. The PCBA board is located between the lamp body and the light distribution mirror. Bowl-shaped light concentrators are arranged on both sides of the protrusion one and protrude downward. LEDs are arranged on the PCBA board corresponding to the positions of the two light concentrators. An optical pattern one is arranged on the bottom surface between the two light concentrators on the protrusion one. Reflective surfaces are arranged on both sides of the upper surface of the light distribution mirror. The light emitted by the LEDs is gathered by the light concentrators and then emitted to the reflective surfaces on both sides. The light is reflected on the optical pattern one and then reflected on the light emission surface, thereby realizing uniform light emission.

[0005] Further, the positions of the two reflective surfaces correspond to the positions of the two light concentrators. The two reflective surfaces are inclined surfaces and both incline to the middle part of the light distribution mirror.

[0006] Further, the light emission surface is located in the middle of the optical pattern one.

[0007] Further, the light concentrators are provided with optical patterns two on the side surfaces. The optical pattern one is dentate.

[0008] Further, the length of the light distribution lens is a, the width is b, a is 207.05mm, b is 34.79mm, the distance between the bottom surface of the lamp body and the top surface of the light distribution lens is d, and d is 34.72mm.

[0009] Compared with the prior art, the beneficial effects of the utility model are that: the utility model increases optical pattern one and optical pattern two on the light distribution lens, cooperates with the reflecting surface, effectively utilizes light and controls the direction of light, ensures uniform light emission, integrally injection molds the light distribution lens, reduces the number of parts, does not specially require the material of the light distribution lens, does not need more LEDs, therefore, reduces the cost, the lamp body and the light distribution lens occupy small space, adopt a small amount of LEDs, do not increase the light guide piece, only rely on the improved light distribution lens to ensure uniform light emission, and can ensure low power of the light source.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0017] The utility model increases the optical structure on the light distribution lens 2, integrally injection molds the light distribution lens 2 under the condition of a small amount of LED 31, still can achieve the uniform light emission effect, meets the regulation requirements, solves the technical problems that the current needs to increase the light guide or thick wall parts to conduct light to complete the uniform light, or the combination of the light uniform material and a plurality of high-power LEDs to complete the uniform light.

Bowl-shaped concentrators 211 protruding downward are provided on both sides of the protrusion 21. LEDs 31 are provided on the PCBA board 3 at the positions corresponding to the two concentrators 211. The number of LEDs 31 is small, which ensures the low power characteristics of the light source. The light emitted by the LED 31 is concentrated by the concentrator 211 to ensure high effective utilization of the light. An optical pattern 212 is provided on the bottom surface between the two concentrators 211 on the protrusion 21. Reflecting surfaces 23 are provided on both sides of the light distribution mirror 2. The light emitted by the LED 31 is concentrated by the concentrator 211 and then emitted to the reflecting surfaces 23 on both sides. The light is reflected by the reflecting surface 23 onto the optical pattern 212. At this time, the optical pattern 212 can disperse the light and then reflect it onto the light emitting surface 24, thereby achieving uniform light output.

[0019] Specifically, the positions of the two reflecting surfaces 23 correspond to the positions of the two concentrators 211. The two reflecting surfaces 23 are inclined surfaces and are both inclined toward the middle of the light distribution mirror 2. The horizontal length of the two reflecting surfaces 23 is consistent with the length of the concentrator 211. The light-emitting surface 24 is located in the middle of the optical pattern 1 212. The light is concentrated by the concentrator 211 and then emitted to the reflecting surface 23. A small part of the light is directly emitted to the light-emitting surface 24 after reflection and then emitted. Most of the light is emitted to the optical pattern 1 212 after reflection, and is then scattered and adjusted by the optical pattern 1 212 before being emitted from the light-emitting surface 24. In this way, the light can be emitted evenly without adding parts such as light guides or thick walls to transmit light, and without the need for a combination of light-uniform materials and multiple high-power LEDs. The structure is ingenious and the cost is low.
