Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a side-mounted combined signal light. Background Technology

[0002] Lenses are widely used in the optical systems of lighting fixtures. Lenses can be designed to focus or disperse light depending on the required function. Existing signal light lenses emit light from the entire surface, lacking a three-dimensional effect. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a side-mounted combined signal light, wherein the light-emitting surface of the lens is stepped and the light-emitting surface has a three-dimensional effect.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a side-mounted combined signal light, including a lamp body, on which one or more light-emitting units with different light-emitting directions are provided. Each light-emitting unit includes a base, a mask, and an optical system. The optical system, in order of light emission direction, includes a light source, a light-diffusing plate, and a lens. The light source includes a lamp board and several LED beads disposed on the lamp board. The lens is annular and includes an incident surface, a reflecting surface, and an emitting surface. The emitting surface is located on the opposite side of the reflecting surface and is stepped, including several stepped surfaces with different heights. Adjacent stepped surfaces are connected by connecting surfaces. The stepped surfaces are located above the incident surface and have optical textures that disperse light. The connecting surfaces are total reflection surfaces. The principle of this utility model: the reflecting surface and connecting surfaces of the lens are both total reflection surfaces, which can improve the brightness of the light emitted from the stepped surfaces and reduce stray light affecting the light emitted from the stepped surfaces. Each stepped surface has a different height and is staggered, creating a floating three-dimensional effect on the entire emitting surface when light is emitted from the stepped surfaces.

[0005] As an improvement, the lens has a triangular cross-section, with the bottom surface of the lens being the light-incident surface, the outer side of the lens being the reflecting surface, and the inner side of the lens being the light-exit surface.

[0006] As an improvement, the angle between the connecting surface and the incident light surface is 70~90°.

[0007] As an improvement, the light-diffusing plate is placed close to the incident surface of the lens.

[0008] As an improvement, the LED beads are distributed according to the shape of the lens incident surface.

[0009] As an improvement, the lamp body is provided with two light-emitting units facing forward and backward respectively.

[0010] As an improvement, the lamp body is provided with three light-emitting units facing forward, backward and side respectively.

[0011] As an improvement, the lamp body is provided with a mounting groove, and the light-emitting unit is disposed in the mounting groove.

[0012] The beneficial effects of this utility model compared with the prior art are:

[0013] Both the lens reflective surface and the connecting surface are total reflection surfaces, which can improve the brightness of the stepped surface and reduce the impact of stray light on the light output of the stepped surface; each stepped surface has a different height and is staggered with each other, so when the stepped surface emits light, it forms a floating three-dimensional effect on the entire light output surface; the light doubling plate can disperse the light of the LED beads, making the light output of the lens more uniform.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] A side-mounted combined signal light includes a lamp body 1 and a plurality of light-emitting units 2 disposed on the lamp body 1; the lamp body 1 is connected to a connecting seat, the connecting seat being integrally formed with the lamp body 1, and the connecting seat being fixed to the side of the vehicle by bolts to realize the side mounting of the light fixture; the lamp body 1 is provided with mounting slots for mounting the light-emitting units 2; according to design needs, one, two, three, etc., light-emitting units can be designed on the lamp body 1, and the orientation of each light-emitting unit is different. This embodiment takes two light-emitting units 2 as an example for explanation, with the two light-emitting units 2 facing forward and backward respectively.

[0020] The light-emitting unit 2 includes a base 24, a mask 21, and an optical system. The base 24 and the mask 21 cooperate to form a closed cavity, and the optical system is disposed within the closed cavity. The optical system includes, in sequence according to the light emission direction, a light source, a light-diffusing plate 23, and a lens 22. The lens 22 includes an incident surface 221, a reflecting surface 222, and an emitting surface 223. The emitting surface 223 is located on the opposite side of the reflecting surface 222. The cross-section of the lens 22 is approximately triangular. The bottom surface of the lens 22 is the incident surface 221, the outer side of the lens 22 is the reflecting surface 222, and the inner side of the lens 22 is the emitting surface 223. The lens 22 is a rotating body. In this embodiment, the lens 22 is annular, adapted to the racetrack-shaped lamp body 1. The emitting surface 223 is stepped, including several stepped surfaces 2232 with different heights. Adjacent stepped surfaces 2232 are connected by a connecting surface 2. The lens 22 is connected at 231. The stepped surface 2232 is located above the light-incident surface 221, and the number of stepped surfaces 2232 is designed according to needs. The stepped surface 2232 has optical textures that disperse light, such as vertical textures or corn kernel textures. The connecting surface 2231 is a total reflection surface 222. The angle between the connecting surface 2231 and the light-incident surface 221 is 70~90°. After the light enters the lens 22 from the light-incident surface 221, part of the light directly exits from the stepped surface 2232, and the other part of the light is reflected by the reflecting surface 222 and the connecting surface 2231 and finally exits from the stepped surface 2232. The light-diffusing plate 23 is closely attached to the light-incident surface 221 of the lens 22. The shape of the light-diffusing plate 23 can be similar to the shape of the light-incident surface 221. The light-diffusing plate 23 can disperse the light from the LED beads, making the light output of the lens 22 more uniform. The light source includes a lamp plate 26 and a plurality of LED beads 25 disposed on the lamp plate 26. The LED beads 25 are distributed according to the shape of the light incident surface 221 of the lens 22. The reflective surface 222 and the connecting surface 2231 of the lens 22 are both total reflection surfaces 222, which can improve the light output brightness of the stepped surface 2232 and reduce the influence of stray light on the light output of the stepped surface 2232. Each stepped surface 2232 has a different height and is staggered with each other. When the stepped surface 2232 emits light, it forms a floating three-dimensional effect on the entire light output surface 223. A decorative cover 27 is provided in the middle of the lamp body 1. The decorative cover 27 is connected to the lamp body 1 by bolts. The decorative cover 27 has a first protrusion for pressing the lamp plate 26 and a second protrusion for pressing the lens 22.
