Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to an optical structure and a lamp for realizing uniform light emission of a lamp with a large inclination. Background Art
[0002] The continuous evolution of automotive technology is driving changes in the automotive lighting industry. Technological advancements and market demands have not only improved energy efficiency but also evolved from initially satisfying lighting and functional needs to creating a variety of novel designs that enhance vehicle recognition. Currently, the diversification of automotive lighting designs is placing increasingly stringent demands on optical structures.
[0003] In some lamps with strong sense of shape, for example, Figure 1 If the internal optical structure of the headlight with a larger inclination as shown in the figure is Figure 2 In the present invention, only one PCB board 03 is provided inside the lamp component 02. Due to the limitation of the installation space, the inner end of the PCB board 03 is limited to the position shown in the figure and cannot be extended to the inner end. The LED light source 04 on the PCB board 03 emits light in the normal direction, which will form a dark area 05 at the inner end of the lamp component 02. In order to avoid the formation of the dark area 05, the prior art adopts the following method. Figure 3 The optical structure shown uses two spliced PCB boards 03. The inner PCB board 03 emits light in the forward direction to illuminate the inner end area of the vehicle lamp component 02, and the outer PCB board 03 is set at an angle to emit light in the normal direction. In the prior art, the two PCB boards need to be equipped with a large number of parts such as wiring harnesses and connectors, which makes the structure complex, has a high failure rate, and the cost of the lamp is relatively high. At the same time, there will also be some dark areas at the splicing point of the two PCB boards. Utility Model Content
[0004] The first purpose of the present utility model is to provide an optical structure that enables uniform illumination of a headlight at a large inclination, in order to address the problems in the prior art that the optical structure of a headlight at a large inclination includes two PCB boards, requires a large number of wiring harnesses, connectors and other parts, has a complex structure, a high failure rate, and a high lamp cost. The second purpose of the present utility model is to provide a headlight.
[0005] In order to achieve the above first purpose, the technical solution adopted by the present utility model is:
[0006] An optical structure for achieving uniform illumination of a headlight at a large inclination angle comprises an inclined headlight component and a PCB board disposed inside the headlight component, the PCB board being inclined and aligned with the inclination direction of the headlight component; a plurality of LED light sources spaced apart along the inclination direction are provided on the PCB board; an optical component is provided above the inner end LED light source, and light emitted by the LED light source can be deflected by the optical component and propagated to the inner end region of the headlight component.
[0007] The utility model adopts the above-mentioned technical solution and only sets an inclined PCB board. By setting optical components, the direction of light emitted by the inner LED light source is deflected. The deflected light is transmitted to the inner end area of the headlight component, avoiding the formation of dark areas, thereby ensuring the uniformity of the lighting effect of the headlight. Compared with the existing technology, the optical structure of the headlight with a large inclination includes two PCB boards, which requires the setting of more wiring harnesses, connectors and other parts, has a complex structure, a high failure rate, and a high cost of the lamp. Under the premise of ensuring the uniform lighting effect of the headlight, the utility model only needs to set one PCB board, reduces the wiring harnesses, connectors and other parts, has a simpler structure, a lower failure rate, and a lower cost of the lamp (the cost increase caused by adding the optical component 1 is far less than the cost reduction caused by reducing the number of PCB boards).
[0008] Furthermore, the optical component is a prism, a lens or a reflector; the prism, the lens and the reflector can all play a role in changing the direction of light propagation, thereby enabling the light of the LED lamp to illuminate the inner end area of the vehicle lamp component to avoid the formation of a dark area.
[0009] Furthermore, the optical component is fixedly mounted on the PCB board; with this arrangement, the overall structure is more compact.
[0010] Furthermore, a buckle is fixed on the optical component, and a slot is provided on the PCB board. The optical component is fixed on the PCB board through the engagement between the buckle and the slot. With this arrangement, the optical component can be installed conveniently and quickly.
[0011] Furthermore, a plurality of the LED light sources are arranged on the PCB board at equal intervals; such an arrangement can make the lighting effect of the vehicle light component uniform.
[0012] To achieve the second purpose, the present invention adopts the following technical solutions:
[0013] A vehicle lamp comprises the above-mentioned optical structure for achieving uniform light emission of a vehicle lamp with a large inclination.
[0014] Compared with the existing technology, the beneficial effects of the present invention are: under the premise of ensuring uniform lighting effect of the car lights, only one PCB board is required, reducing parts such as wiring harnesses and connectors, resulting in a simpler structure, lower failure rate, and lower lamp cost; the car lights have the same technical effect as the aforementioned optical structure for achieving uniform lighting of large-angle car lights.

[0020] The present invention will be described in detail below with reference to the accompanying drawings.
[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0022] Example 1: This example provides an optical structure for achieving uniform light emission at large inclinations. Figure 4 As shown, the light assembly 2 includes an inclined light assembly 2 and a PCB board 3 disposed inside the light assembly 2. The PCB board 3 is disposed at an angle and aligned with the tilt direction of the light assembly 2. A plurality of LED light sources 4 are disposed on the PCB board 3 and spaced apart along the tilt direction. An optical component 1 is disposed above the inner end of the LED light source 4. Light emitted by the optical component 1 can be deflected by the optical component 1 and then transmitted to the inner end region of the light assembly 2. The light assembly 2 is a decorative frame for the light. A lampshade (not shown) is mounted outside the decorative frame and aligned with the tilt direction of the decorative frame.
[0023] It should be noted that "the PCB board 3 is tilted and aligned with the tilt direction of the lamp component 2" only means that the PCB board 3 and the lamp component 2 are tilted in the same direction. It does not mean that the tilt angle of the PCB board 3 is exactly the same as the tilt angle of the lamp component 2. The tilt angles of the two can be the same or there can be a small deviation.
[0024] The optical component 1 can be any optical element that can deflect the propagation direction of light. The optical component 1 can be a prism, a lens, or a reflector. The optical component 1 is a common optical component with low cost. The cost increase caused by adding the optical component 1 is far less than the cost reduction caused by reducing the number of PCB boards.
[0025] The optical component 1 is fixedly mounted on the PCB board 3;
[0026] A buckle is fixed on the optical component 1, and a slot is provided on the PCB board 3. The optical component 1 is fixed on the PCB board 3 by the engagement of the buckle and the slot;
[0027] Several LED light sources 4 are arranged on the PCB board 3 at equal intervals.
[0028] The utility model adopts the above-mentioned technical solution and only provides an inclined PCB board 3. By providing an optical component 1, the direction of the light emitted by the inner LED light source 4 is deflected, and the deflected light is transmitted to the inner end area of the headlight component 2, avoiding the formation of a dark area, thereby ensuring the uniformity of the lighting effect of the headlight. Compared with the prior art, the optical structure of the headlight with a large inclination includes two PCB boards, which requires the provision of more wiring harnesses, connectors and other parts, has a complex structure, a high failure rate, and a high cost of the lamp. Under the premise of ensuring the uniform lighting effect of the headlight, the utility model only needs to provide one PCB board, reduces the wiring harnesses, connectors and other parts, has a simpler structure, a lower failure rate, and a lower cost of the lamp (the cost increase caused by adding the optical component 1 is far less than the cost decrease caused by reducing the number of PCB boards).
[0029] Example 2, a vehicle lamp, comprising the above-mentioned optical structure for achieving uniform light emission at a large inclination.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
