Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an optical structure for automotive lighting. Background Technology

[0002] Existing automotive lighting optical structures (such as...) Figure 2 As shown, LED particles are mounted on a light source board, with their light-emitting center aligned with the bottom incident end of the lower concentrator. The reflective surface is directly integrated into the surface of the lower concentrator. The light emitted by the light source must first be initially guided by the lower concentrator, then reflected by its reflective surface, and finally projected onto the diffusion pattern surface of the upper thick-walled component before exiting. While this design achieves basic light distribution, it has significant drawbacks: to simultaneously support the reflective surface and ensure light converging effect, the lower concentrator must be designed as an integral thick-walled structure, resulting in a substantial increase in its weight. This directly increases the overall weight of the lamp, contradicting the current automotive industry's trend towards lightweight design to reduce energy consumption and improve handling. Furthermore, the lower concentrator is made of optical-grade materials; increased weight means increased material usage, directly leading to higher component costs and making it difficult to meet automakers' cost control requirements.

[0003] As automotive lighting technology advances towards higher optical efficiency, lower weight, and lower cost, the existing "integrated reflector-concentrator" design can no longer simultaneously meet the demands for performance, lightweighting, and cost. Therefore, there is an urgent need in this field for a new automotive lighting optical structure that optimizes the collaborative design of the reflector and concentrator, achieving concentrator weight reduction and cost optimization while ensuring light distribution accuracy and structural strength, thus adapting to the technological development requirements of the automotive industry. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an optical structure for vehicle headlights, aiming to reduce the weight and cost of vehicle headlights.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] The vehicle headlight optical structure includes a headlight housing, an internal structure within the headlight housing, a light source board, and a concentrator. The light source board has a light source corresponding to the concentrator. The internal structure above the concentrator has a reflective surface. After the concentrator collects light, it shines onto the internal structure with the reflective surface and is then reflected off by the reflective surface.

[0007] Further or preferred:

[0008] The internal structure is a support member, and the part of the support member above the concentrator is an inclined structure with a reflective surface.

[0009] The light source board is fixed on the support.

[0010] The concentrator is fixed to the support.

[0011] The light source plate is horizontally arranged, the light source is located on the upper surface of the light source plate, and the lower part of the condenser is provided with a groove corresponding to the light source.

[0012] The support component is an integral injection-molded structure, and the inclined structure is an inclined plate.

[0013] The inclined plate is provided with an aluminum plating layer.

[0014] The headlight housing has an upper thick-walled component, and the upper thick-walled component has patterns on both the inner and outer sides. The inner pattern is set to correspond to the inclined plate.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] The headlights of this vehicle feature a reasonable optical structure design, with the reflector and concentrator designed separately. The structure of the concentrator is simplified, retaining only the concentrating port part that performs the basic focusing function, while removing the redundant part that carries the reflector in the original integrated structure. At the same time, the reflector is transferred to the support component, and by designing optical patterns on the surface of the support component and using a shielding aluminum plating process, the reflector meets the requirements for light reflection and light distribution accuracy, effectively reducing the weight and material cost of the headlights.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0023] like Figure 1 As shown, the vehicle lamp optical structure includes a lamp housing and an internal structure, a light source board, and a concentrator located inside the lamp housing. The light source board is equipped with a light source corresponding to the concentrator. The internal structure above the concentrator is designed with a reflective surface. After the concentrator collects light, it shines onto the internal structure with the reflective surface and is then reflected off by the reflective surface.

[0024] Preferably, the internal structure is a support member, and the part of the support member above the concentrator is an inclined structure with a reflective surface.

[0025] This invention redesigns the concentrator structure, retaining only the concentrating port part that performs the basic concentrating function, and removing the redundant part that carries the reflective surface in the original integrated structure; at the same time, the reflective surface is transferred to the support component, effectively reducing the weight and material cost of the vehicle headlight.

[0026] Both the light source board and the condenser are fixed on the support, with integrated positioning and a compact structure; positioning can be achieved using screws or snap-fit ​​structures.

[0027] The light source board is set horizontally, and the light source is set on the upper surface of the light source board. The lower part of the condenser has a groove corresponding to the light source. The condenser only retains the focusing port part, which greatly reduces the weight.

[0028] The support component is an integral injection-molded structure, and the inclined structure is an inclined plate with an aluminum-plated layer; the structure is reasonably designed, integrated, and compact.

[0029] The headlight housing has an upper thick-walled component with patterns on both the inner and outer sides. The inner pattern corresponds to the inclined plate.

[0030] To completely avoid the drawbacks of existing automotive lighting structures; such as Figure 1 As shown, this utility model optimizes the collaborative design of the reflective surface and the concentrator, achieving weight reduction and cost optimization of the lower concentrator while ensuring optical performance and structural strength. The specific structure is as follows:

[0031] 1. Light source and concentrator layout: LED particles 2 are still fixed on the surface of light source board 1, and their light emission center is precisely aligned with the bottom incident end of concentrator 5 to ensure efficient light incidence;

[0032] 2. Separate design of reflector and concentrator: The structure of concentrator 5 is simplified, retaining only the concentrating port part that realizes the basic concentrating function, and removing the redundant part that carries the reflector in the original integrated structure; at the same time, the reflector 4 is transferred to the support 3, and by designing optical patterns on the surface of the support 3 and using a shielding aluminum plating process, the reflector 4 meets the requirements of light reflection and light distribution accuracy.

[0033] 3. Light path: The light emitted by the LED particle 2 is directly projected onto the reflective surface 4 on the support 3 through the focusing port of the concentrator 5. After being accurately reflected by the reflective surface 4, it is finally projected onto the diffusion pattern surface of the upper thick-walled part 6 and emitted outward.

[0034] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0035] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
