Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle lamp structure technology, specifically to a low-cost vehicle lamp structure with uniform light. Background Technology
[0002] More and more car models are adopting a design with multiple small-sized, thick-walled signal lights. Existing technologies generally use two sets of light source structures, but PCBA particles (i.e., LED beads that emit light on the PCBA) are expensive. Therefore, in order to solve this technical problem, this application uses a single light source structure to reduce the cost of the car light structure. In addition, in order to ensure uniform light emission, a diaphragm is added to change the light non-uniformity of the traditional reflector solution, so as to obtain a car light structure that combines low cost and uniform light emission.

[0027] Compared with the prior art, the beneficial effects of this utility model are:
[0028] In this invention, by providing a single light-emitting element and a first reflector, there is only one set of light sources in the structure. The light emitted from the side is reflected by the first reflector into the thick-walled element for light emission, which reduces the cost of the signal light.

Detailed Implementation
[0033] 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.
[0034] like Figure 1-3 As shown, this utility model provides a technical solution: a low-cost, uniformly lit vehicle lamp structure, including a housing, the housing including a lamp cover 100 and a lamp housing 300 that interlock with each other, and a first optical structure 400 and a second optical structure 500 are provided in the cavity of the housing. The first optical structure 400 can be used to save costs by using only one set of light sources in environments with thick walls, while the second optical structure 500 aims to improve the uneven light caused by relying on a single reflection source.
[0035] Among them, such as Figure 2 As shown, the first optical structure 400 and the second optical structure 500 respectively have a first light-emitting element 401 and a second light-emitting element 501 for emitting light. A first reflector 402 is provided below the light-emitting direction of the first light-emitting element 401. The light source of the first light-emitting element 401 is reflected by the first reflector 402. A multi-thick wall is provided at the light-emitting port of the first reflector 402. The multi-thick wall includes a first thick-walled element 403 and a second thick-walled element 405. The two thick-walled elements have light-inlet surfaces and light-outlet surfaces on opposite sides.
[0036] When in use, the first light-emitting element 401 is turned on, and the light emitted by the first light-emitting element 401 shines on the reflective surface of the first reflector 402. The light is reflected by the reflective surface and enters the light-inlet surface of the first thick-walled element 403 and the second thick-walled element 405. After being transmitted in the two thick-walled elements, the light is emitted from the light-outlet surface to form a light path. The light path passes through the lamp cover 100 and shines in front. Compared with the prior art, the first light-emitting element 401 only uses one set of light source structure, which effectively reduces the cost of the vehicle lamp.
[0037] Furthermore, such as Figure 2As shown, the first thick-walled component 403 and the second thick-walled component 405 have the same height. Since the first light-emitting component 401 is a side-projection component, the light emitted is more uniform when the heights of the two thick-walled components are the same.
[0038] Furthermore, such as Figure 2 As shown, a light-shielding member 404 is also provided between the first thick-walled member 403 and the second thick-walled member 405.
[0039] Furthermore, such as Figure 2 As shown, the headlight structure also includes a first decorative frame 200 for support and protection.
[0040] Furthermore, considering that using a single reflector source would sacrifice some of the uniformity of the light output, in order to ensure that the headlights still have good uniform light after being turned on, such as... Figure 2 As shown, the second optical structure 500 also includes a thick-walled unit 502 located at the light outlet of the second light-emitting element 501. A second reflector 503 is also disposed below the thick-walled unit 502. A diaphragm 504 is disposed in front of the light outlet of the second reflector 503. The diaphragm 504 has a microstructure. The light source of the second light-emitting element 501 is scattered by the thick-walled unit 502 and then reflected horizontally through the diaphragm 504 to finally form light.
[0041] In use, when the vehicle is started, the second optical structure 500 is also illuminated. The light emitted by the second light-emitting element 501 first passes through the thick-walled unit 502, which is an SBL thick-walled unit, forming uniform light under the action of the thick-walled unit 502. This light then shines on the reflective surface of the second reflector 503, and after reflection, it continues to propagate onto the diaphragm 504. Due to the microstructure of the diaphragm 504, the light is diffused and deflected, ultimately forming uniform light with a wide coverage area that passes through the lamp cover 100 and illuminates the front, providing the driver with a good field of vision and improving driving safety. This solution is used to improve the uniform light sacrificed by the single reflective source used in the first optical structure 400. The first optical structure 400 and the second optical structure 500 cooperate with each other to form a light structure that combines low cost and uniform light, for use in vehicle lights.
[0042] Furthermore, such as Figure 2 As shown, both the first light-emitting element 401 and the second light-emitting element 501 are integrated structures of PCB and LED particles.
[0043] Furthermore, such as Figure 3As shown, the diaphragm 504 is a BVT C-series diffusion diaphragm, preferably C-HE15, C-HE20, C-HE30, C-HE40 or C-HE55. The microstructure on the surface of the diaphragm 504 diffuses the concentrated light into multi-angle scattering, thereby expanding the light coverage area. In addition, the angle of the light source can be changed by the specific arrangement of the microstructure, so that the light source is rotated and deflected to the target direction, thereby achieving uniform overall light coverage.
[0044] Furthermore, the inner lining 505 and the optical film 504 are also fixedly connected to each other by ultrasonic welding.
[0045] Furthermore, such as Figure 1-2 As shown, the headlight structure also includes a second decorative frame 600 for supporting and protecting the second optical structure 500.
[0046] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
