Abstract

The invention relates to a light-emitting structure and a vehicle lamp. The light-emitting structure comprises a light source, a light guide piece and a light-emitting piece, wherein a light emittingsurface of the light source faces one end surface of the light guide piece, the light-emitting piece comprises connecting parts located on one side edge of the light emitting piece, the connecting parts are connected with the light guide piece so that at least part of light passing through the light guide piece can be emitted into the light emitting piece from the connecting parts, the number of the connecting parts is multiple, the connecting parts are arranged at intervals, and the area of the cross section of the joint of each connecting part and the light guide piece is gradually increasedin the first direction, or, the number of the connecting part is one, thickness of the connecting part is gradually increased in the first direction, and the first direction is the direction that a light incident surface of the light guide piece points to an opposite surface of the light guide piece. The light-emitting structure is advantaged in that the light emitted into the light-emitting parts from one side close to the light source is reduced, so the light-emitting parts emit light more uniformly.

Description

technical field [0001] The invention relates to the technical field of optical systems, in particular to a light emitting structure and a vehicle lamp. Background technique [0002] As the shape of car lights keeps changing, more and more novel and unique eye-catching car light shapes have become a goal of car light design. In order to achieve complex and changeable lighting effects in various areas, uniform lighting on the entire surface has become a method to achieve this goal. [0003] In the light-emitting structure of traditional car lights, the light source is arranged on one end of the long light guide, and the side of the light guide is connected to the light guide plate. The effect of the surface of the light guide plate glowing. [0004] However, for the light guide, the closer to the light source, the higher the light energy, and most of the light enters the light guide plate at the entrance of the light guide, so that the light at the front end of the light gui...
