Description
Technical Field
[0001] This utility model belongs to the field of automotive equipment, and specifically relates to a light-focusing and refraction structure for LED vehicle lights. Background Technology
[0002] LED automotive lights refer to automotive lighting fixtures that use light-emitting diodes (LEDs) as the light source. They have many advantages such as energy saving, environmental friendliness, long lifespan, and fast response, and are widely used in various automotive lighting applications. However, current LED automotive lights have certain limitations in their lighting optical structure design. When LED automotive lights emit light, the light cannot be effectively focused and precisely refracted, resulting in scattered and unfocused illumination. This shortcoming means that while the illumination range is wide, the brightness is not concentrated enough when driving at night, making it difficult for the driver to clearly distinguish distant objects and road conditions, thus affecting driving safety.
[0003] The conventional solutions are to add a focusing lens to the outside of the LED light or replace it with a suitable reflector. However, adding a focusing lens increases the overall size and weight of the light fixture, which may cause layout difficulties in the limited installation space of the vehicle and may also affect the aesthetic harmony of the light fixture. Replacing the reflector faces compatibility problems. Different vehicle models have different light fixture structures, making it difficult to find a perfectly compatible reflector. Moreover, the replacement process is relatively complex, requiring specialized tools and techniques, which increases maintenance costs and difficulty. Therefore, a new structure is needed to solve the above technical problems. Utility Model Content

The end of the push rod away from the adjusting rod is connected to the inner surface of the buffer plate.
[0010] In a preferred embodiment, the upper surface inside the lamp housing is connected to an adjusting member via an adjusting rod. Inside the lamp housing, two adjusting plates are symmetrically hinged via the adjusting member. The two adjusting plates have the same structure and are designed with an arc shape.

The adjustment component includes an adjustment plate for adjusting the light. The adjustment plate is hinged inside the lamp housing by a hinge. In use, the light distribution is optimized by the adjustment plate (in actual use, the user can install a reflector on the inner surface of the adjustment plate), which can reduce the waste of light energy and concentrate more light on the area that needs to be illuminated, making it convenient for the user.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1 to 4This utility model provides a technical solution: a stable support structure for an LED automotive lamp, comprising: a lamp housing 100, an adjustment component 200, and a buffer component. The adjustment component 200 for adjusting the light emitted by the LED beads is installed on the outer and inner surfaces of the lamp housing 100. A buffer component for buffering the lamp housing 100 is installed on the rear surface of the lamp housing 100. The adjustment component 200 includes an adjustment plate 230 for adjusting the light emitted by the lamp housing 100, which is hinged to the inside of the lamp housing 100 via a hinge. The buffer component includes a buffer member 310 for buffering the lamp housing 100, with the buffer plate 300 installed at the end of the buffer member 310 furthest from the lamp housing 100.
[0026] Please see Figures 1 to 4 As the first embodiment of this utility model: both the front and rear surfaces of the lamp housing 100 are provided with square openings 101, the diameter of the front square opening 101 is larger than the diameter of the rear square opening 101, and an mounting plate 110 is integrally formed on the rear side inside the lamp housing 100.
[0027] A lamp holder 120 is installed at the center of the front surface of the mounting plate 110. An LED lamp bead is electrically connected to the front surface of the mounting plate 110 through the lamp holder 120. Two sliding grooves 102 are symmetrically opened in a figure-eight structure on the rear edge of the upper surface of the lamp housing 100.
[0028] The adjustment assembly 200 also includes an adjustment member 240, an adjustment rod 210, a push rod 220, and a limiting member. The limiting member is integrally formed at the center of the rear edge of the upper surface of the lamp housing 100, and the push rod 220 passes through the center of the front surface of the limiting member.
[0029] Two sliding grooves 102 are slidably connected to the upper surfaces of the two sliding grooves 102 with an adjustment rod 210 in a figure-eight shape. The two adjustment rods 210 are hinged together, and a push rod 220 is hinged at the hinge of the two adjustment rods 210. The end of the push rod 220 away from the adjustment rod 210 is connected to the inner surface of the buffer plate 300.
[0030] An adjusting member 240 is connected to the upper surface of the interior of the lamp housing 100 via an adjusting rod 210. Two adjusting plates 230 are symmetrically hinged inside the lamp housing 100 via the adjusting member 240. The two adjusting plates 230 have the same structure and are designed with an arc shape.
[0031] The lower surface of the adjusting plate 230 is connected to another adjusting member 240. The two adjusting members 240 have the same structure. The two adjusting plates 230 are opened and closed by the adjusting member 240, the adjusting rod 210 and the push rod 220.
[0032] In use, the user first installs the lamp housing 100 inside the vehicle body using the buffer 310. After installation, the user installs the LED bulb inside the mounting plate 110 inside the lamp housing 100. After completing the above steps, when using the LED bulb, the user can install an electric push rod on the outer surface of the buffer plate 300, connecting the telescopic rod of the electric push rod to the push rod 220 (the electric push rod is existing technology, and its specific working principle and installation principle are not described here). The user can then activate the drive to extend and retract the telescopic rod of the electric push rod, thereby driving the push rod 220 forward and backward. This causes the adjusting rod 210 connected to the push rod 220 to move along the slide groove 102, thereby causing the adjusting rod 210 to move with the adjusting member 240 inside the lamp housing 100, thus opening and closing the adjusting plate 230 inside the lamp housing 100. The adjustment plate 230 adjusts the light emitted by the LED beads. When focused reflection is needed, simply close the adjustment plates 230 (not completely closed to avoid blocking the light emitted by the LED beads). When the adjustment plates 230 are closed, the light emitted by the LED beads shines on the inner surface of the adjustment plate 230, collecting and reflecting the divergent light, thus achieving a focused effect and preventing the light emitted by the LED beads from scattering. Users can adjust the opening and closing degree of the two adjustment plates 230 by extending the telescopic rod of the electric push rod, thereby adjusting the focusing degree of the two adjustment plates 230, which is convenient for users. Because the adjustment plates 230 optimize the light distribution (in actual use, users can install a reflector on the inner surface of the adjustment plates 230), light energy waste can be reduced, allowing more light to be concentrated on the area that needs illumination, making it convenient for users.
[0033] Please see Figures 1 to 4 As a second embodiment of this utility model: a buffer 310 is installed at each of the four corners of the rear surface of the lamp housing 100. The buffer 310 is a spring damper. The end of the buffer 310 away from the lamp housing 100 is connected to the inner surface of the buffer plate 300. A rubber pad is installed on the side surface of the buffer plate 300 away from the buffer 310. The buffer plate 300 is installed inside the vehicle body device by screws and threaded holes.
[0034] A gap is provided between the inner surface of the buffer plate 300 and the rear surface of the lamp housing 100;
[0035] When the front surface of the lamp housing 100 is subjected to ordinary vibrations from external factors during use, the rear surface of the lamp housing 100 is fitted with a buffer plate 300 via a buffer member 310. The buffer plate 300 then holds the lamp housing 100 inside the vehicle body. When the lamp housing 100 is vibrated, the buffer assembly helps maintain a relatively stable position, preventing the lamp housing 100 from shifting or shaking due to vibration or collision. This ensures that the light axis of the LED car light remains stable. In conjunction with the operation steps of the first embodiment, two closed adjustment plates 230 are installed in front of the LED light, serving as a protective barrier to prevent external factors from directly affecting the LED beads and causing damage.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
