AI Technical Summary

Technical Problem

The existing car lighting optical systems require a certain spacing between the reflector and the inner light distribution mirror, resulting in a large demand for the overall optical system space, which cannot compress the front and rear space of the lamp, especially not suitable for flat lamps.

Method used

A multi-reflective mirror structure is adopted, including the outermost car lamp housing, a double mirror and a light source part. Both ends of the bi-reflective mirror have reflection surfaces. The first reflective surface is arc-shaped, and the second reflective surface is curved or ellipsoidal. The light beam is reflected through the arc-shaped surface to form a parallel beam, and then diffuses along the curved surface or ellipsoidal surface, and finally emits the car light.

Benefits of technology

Through the dual-reflector structure, the effect of traditional mirror plus light distribution is achieved, and the space occupies less, which is suitable for flat car light fixtures, and the flexible layout of the PCB board meets different space needs.

Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamps and lanterns, and particularly relates to a multi-reflector structure for optimizing the spatial layout of vehicle lamps. Background Art

[0002] Car headlights are tools for lighting the road at night and are also tools for issuing various vehicle driving signals. They are generally divided into headlights, taillights, turn signals, etc. According to the type of light, they can be divided into xenon lamps, LED lamps, halogen lamps and laser lamps, etc.

[0003] At present, most of the signal lights on the market are optical systems composed of reflectors and internal light distribution mirrors. The reflectors are usually in the shape of a rotating parabola. This shape can make the light emitted by the bulb form a parallel beam after reflection, thereby significantly enhancing the brightness and greatly increasing the illumination range and distance. The light distribution mirror can diffuse and distribute the light beam reflected by the reflector to make the lighting uniform, thereby meeting the customer's lighting uniformity requirements. There needs to be a certain distance between the reflector and the internal light distribution mirror to make the light mixing between multiple particles uniform and avoid the problem of overall lighting granularity.

[0004] However, the optical system composed of a reflector + an inner light distribution mirror still has some defects. Since there needs to be a certain distance between the reflector and the inner light distribution mirror, such a design requires a large space for the overall optical system during assembly, making it impossible to compress the space in front and behind the lamp, which is especially unfriendly to some flat lamps.

[0005] In view of the above problems, the applicant proposes a multi-reflector structure that optimizes the spatial layout of vehicle lights to solve the above problems. Utility Model Content

[0007] The technical solution of the utility model is achieved in this way:

[0008] A multi-reflector structure for optimizing the spatial layout of a headlight, comprising an outermost headlight housing, a double reflector disposed on the inner side of the headlight housing, and a light source portion for providing a light beam disposed on the inner side of the double reflector;

[0009] Both ends of the double reflector have reflecting surfaces, the first reflecting surface is close to the light source and is an arc-shaped surface, the second reflecting surface is close to the light outlet of the lamp housing and is a curved surface, the light beam from the light source is reflected by the arc-shaped surface to form a parallel light beam, and then diffused and distributed along the curved surface, and finally emitted along the light outlet of the lamp.

[0010] Furthermore, the multi-reflector structure also includes a PCB board.

[0011] Furthermore, the PCB board is arranged on the inner side of the lamp housing in a vertically inclined or a horizontally inclined manner.

[0012] A multi-reflector structure for optimizing the spatial layout of a headlight, comprising an outermost headlight housing, a double reflector disposed on the inner side of the headlight housing, and a light source portion for providing a light beam disposed on the inner side of the double reflector;

The double reflector is used to replace the traditional reflector plus the light distribution mirror, which has the same effect and occupies less space, and is suitable for flat car lamps;

[0016] 2. In the present invention, by providing a PCB board, the arrangement of the PCB board can be carried out according to the different positions of the double reflectors, which is more flexible and convenient to be arranged in different vehicle lamps. BRIEF DESCRIPTION OF THE DRAWINGS
