Description

Car lamp structure for realizing multi-level thick-wall lighting mode by single PCB (printed circuit board)

Technical Field

The utility model relates to an automotive lighting technical field, concretely relates to realize car light structure of multi-level thick wall lighting mode through single PCB board.

Background

The car light is an indispensable safety device on the car, the development of the car light goes through a plurality of stages such as halogen, xenon, LED, laser, and the like, and the corresponding optical reflection structure also goes from the earliest reflection bowl to the current popular lens, light guide and thick wall. Among them, the thick wall is more and more widely used in the car light, such as chinese patents CN208886650U, CN209026739U, etc.

The search shows that the existing various thick walls can only realize the lighting appearance of a single line, and if the lighting effect of multiple layers is realized, the number of the thick walls needs to be increased, so that the cost is increased and the assembly is complicated. Although it is also possible to achieve a multi-level lighting effect by double-colored injection molding of the inner lens, such a vehicle lamp lacks a stereoscopic impression given to a person by a thick wall.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above-mentioned problem that current car light thick wall spare exists, provide the thick wall of a novel structure and corresponding car light. After light emitted by the single PCB is reflected by the plurality of step-shaped reflecting surfaces on the thick wall, the multi-level thick wall lighting effect is achieved. In order to achieve the above object, the utility model adopts the following technical scheme:

the vehicle lamp structure with the multilayer thick-wall lighting mode realized by the single PCB mainly comprises the PCB and the thick wall; the thick wall has a multilayer step-shaped structure, and the end part of each layer of step is provided with a reflecting surface; after light rays emitted by a light source on the PCB enter the thick wall, the light rays are reflected by the reflecting surfaces of all the layers of steps, and therefore the multi-level lighting effect is achieved.

Further, the thick wall has a stepped structure of not more than 10 layers, corresponding to a lighting effect of up to 10 layers.

Furthermore, the thick wall has a two-layer ladder-shaped structure, and two groups of light sources are correspondingly arranged on the PCB.

Furthermore, the light emitting surface of each layer of the stepped structure is rectangular or circular.

Furthermore, a transition body is arranged between two adjacent layers of the stepped structures, and one side of the transition body, which is close to the reflecting surface, is vertical to the light source.

Furthermore, a groove is arranged on one side of the transition body close to the light-emitting surface, and one end of the groove is closed while the other end is open. The design of the groove has multiple purposes: firstly, the fixing position of the lamp holder is provided for connecting with other parts (such as a decorative frame), secondly, materials are saved, and thirdly, stray light scattered out is shielded.

Furthermore, the included angle between the reflecting surface at the end part of each layer of ladder and the PCB is 45 degrees.

Furthermore, the light source is selected from any one of a halogen light source, an LED light source, a xenon light source and a laser light source, and the number of the light sources is not less than the number of the reflecting surfaces.

Furthermore, the thick wall and the PCB are connected together through bonding, clamping and screws.

Compared with the prior art, the utility model discloses following beneficial effect has: (1) the thick wall is brand-new designed, so that the thick wall has a multilayer stepped structure in the depth direction of the reflecting surface, and the reflecting surface at the end part of each layer can reflect light rays out to form a multilayer lighting effect; (2) the whole structure is simple, the manufacturing and using cost is low, and the assembly difficulty is almost unchanged; (3) the lighting effect is more diversified and beautiful, the identification degree is high, the scientific and technological sense is stronger, and the economic benefit is better.

The LED light source comprises a PCB (printed circuit board) 1, a light source 2, a thick wall 3, a first-stage stepped structure 4, a second-stage stepped structure 5, a transition body 6, a groove 7, a first reflecting surface 8, a second reflecting surface 9 and a light emitting surface 10.

Detailed Description

In order to fully understand the technical solutions and advantages of the present invention, the following embodiments are further described with reference to the accompanying drawings.

In a vehicle lamp structure shown in fig. 1-2, a main body is a PCB board 1 and a thick wall 3, which are fixedly connected together to form a typical side light structure. Two rows of LED lamp beads (namely, light sources 2) are welded on the surface of the PCB board 1 side by side. The structure of the thick wall 3 is completely different from the similar products in the market, and the thick wall comprises a first step-shaped structure 4, a second step-shaped structure 5 and a transition body 6 connecting the first step-shaped structure and the second step-shaped structure. A first reflecting surface 8 and a light emitting surface 10 are respectively arranged at two ends of the first stepped structure, a second reflecting surface 9 and a light emitting surface 10 are respectively arranged at two ends of the second stepped structure, and a groove 7 with one closed end and one open end is arranged outside the transition body 6. The first reflecting surface 8 and the second reflecting surface 9 are arranged in parallel, and the included angle between the first reflecting surface and the second reflecting surface and the PCB 1 is 45 degrees.

The working principle of the car lamp structure is as follows: LED lamp pearl on the PCB board is luminous after the circular telegram, and light gets into and is gone out by first plane of reflection, the horizontal reflection of second plane of reflection respectively behind the thick wall, passes the thick wall light emitting area and jets out, realizes the double-deck effect of lighting from this.

In addition, the structure of the thick wall can be adjusted according to the actual situation, the stepped structure and the number of light sources are flexibly increased, and then the lighting effect of 3 layers or more is achieved.
