Light guiding structure of lamp, driving lamp and vehicle

Abstract

The invention relates to the technical field of illumination, and provides a light guiding structure of a lamp, a driving lamp and a vehicle. The light guiding structure of the lamp comprises a light source, a first reflecting piece, a second reflecting piece and a light guiding piece, wherein the first reflecting piece is provided with a first reflecting face, the first reflecting face and the light source are correspondingly arranged, the second reflecting piece is provided with a second reflecting face, the second reflecting face and the first reflecting face are correspondingly arranged, the light guiding piece and the second reflecting face are correspondingly arranged, the light guiding piece is provided with a light emitting face and a light incident face, and light reflected by the second reflecting face can enter the light guiding piece through the light incident face and can be emitted out from the light emitting face. By secondarily reflecting light emitted by the light source, the light is distributed in a needed distribution mode, and the light guiding structure is simple and easy to produce and manufacture.

Description

technical field [0001] The invention relates to the technical field of illumination, in particular to a light guide structure of a lamp, a running lamp and a vehicle. Background technique [0002] With the development of modern industry, LED (Light Emitting Diode) has gradually been widely used in the field of automotive lighting due to its advantages of long life, low energy consumption, and simple structure. And in order to increase the sense of fashion, technology and delicacy of the lamp, a light guide structure with a light guide is usually provided to improve the lighting effect of the LED. [0003] At present, in the lighting structure of vehicles, there are usually two types of light guide structures: 1. The LED light source is directly applied to the light guide and the light is transmitted through the light guide. This light guide structure has a higher light transmission efficiency, but the lighting effect The continuity and uniformity of the light guide are ofte...

Problems solved by technology

[0003] At present, in the lighting structure of vehicles, there are usually two types of light guide structures: 1. The LED light source directly acts on the light guide and transmits light through the light guide. This light guide structure has a higher light transmission efficiency, but the lighting effect The continuity and uniformity of the light guide are often not ideal, and the structure of the light guide is complex, and the molding process is difficult

2. The light guide strip is hidden under the light guide. The light guide strip achieves uniform luminescence and transmits light through the front light guide. This light guide structure has a better lighting effect, but the structure of the light guide plus light guide makes the The light transmission efficiency is low, and a high-power light source is required to meet the use requirements, which wastes energy and has high requirements for the heat dissipation performance of the lamp
