Abstract

The invention relates to a light guide piece, an automobile lamp and an automobile and belongs to the technical field lamination. The light guide piece is a sheet made of a highly transparent material. Patterns are etched in one surface of the sheet. The surface area, where the patterns are etched, of the sheet is a light emitting surface. Light rays enter the interior of the sheet from the end surface of the sheet, and total reflection is performed. When passing through the area, where the patterns are etched, of the sheet, the light rays are shot out of the surface area, where the patterns are etched, of the sheet. The automobile lamp comprises the light guide piece, light sources are arranged on one end surface of the light guide piece, light rays shot from the light sources enter the interior of the light guide piece from one end surface of the light guide piece, part of the light rays are shot out of other end surfaces of the light guide piece after being subjected to total reflection of the interior of the light guide piece, and part of the light rays are shot out of the surface area, where the patterns are etched, of the light guide piece. The automobile comprises the automobile lamp. By means of the light guide piece, the automobile lamp and the automobile, the similar organic light-emitting diode (OLED) area source lighting effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of illumination, in particular to a light guide sheet, an automobile lamp and an automobile. Background technique [0002] At present, surface-based light sources have the characteristics of soft light, no eye damage, power saving, and natural light, and have been widely used in the design of car lights. Among them, OLED (Organic Light-Emitting Diode, organic light-emitting diode, also known as organic electric laser display, organic light-emitting semiconductor) has the characteristics of self-illumination, uses very thin organic material coating and glass substrate, and is widely used in the design of car lights. Widely used, but its cost is high, and there are functional reliability problems in temperature vibration performance and life. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a light guide sheet, an automobile lamp and an automo...
