Light guide structure, light-emitting assembly, light-emitting device and vehicle

Abstract

The invention relates to a light guide structure, a light-emitting assembly, a light-emitting device and a vehicle. The light guide structure comprises a structure body, a light receiving surface, a light splitting surface, a deflection reflection surface and a light emitting surface. Light emitted by a light source outside the structure body of the light guide structure is collimated by the lightreceiving surface to form collimated light, and the collimated light is transmitted to the light splitting surface in the structure body in the approximately parallel direction, is received and reflected by a main light splitting surface to form main split light, and is received and reflected by a side light splitting surface to form side split light; the side split light is received by the deflection reflection surface on the transmission path and is further reflected to form side emission light; and the side emission light and the main split light penetrate through the light emitting surface and emit light to the outside of the structure body to form illumination. After being collimated and guided by the light guide structure, the light can be completely emitted from the preset light emitting surface to form a shape, the light cannot be freely scattered outwards, a light emitting area of 30-40 mm can be uniformly illuminated by utilizing a single light source, and the energy of thelight source can be more effectively utilized.

Description

technical field [0001] The invention relates to the field of lighting structure design, in particular to a light guide structure, a light-emitting component, a light-emitting device and a vehicle. Background technique [0002] In current signal lamps, light guide structures need to be used to collimate light. Commonly used thick-walled light guide structures mainly include direct-light, reflective, and thick-walled light-guide structures combining direct light and reflection. like figure 1 Shown is a thick-walled light guide structure 1 that combines direct light and reflection, which mainly uses the direct coupling surface 1-1 and the indirect coupling surface 1-2 as the light receiving surface to collimate light: among them, the light source O emits light, and the light directed to the area where the direct coupling surface 1-1 is refracted by the direct coupling surface 1-1 is refracted and then sent out, and the light in this area is collimated; the light directed to t...
