Problems solved by technology

[0003] In traditional light-emitting devices that use OLEDs as light sources, OLEDs are simply laid on a preset fixed surface. However, due to the characteristics of OLEDs that emit light by themselves, and the light propagates in all directions at the same time, the traditional application of OLEDs ignores the direction of OLED light. Adjustment, resulting in uneven light of the light emitting device, and low light utilization efficiency

Abstract

The invention discloses an OLED luminous device and an automobile rear lamp, and relates to the technical field of illumination equipment. The OLED luminous device and the automobile rear lamp have the main goals of reflecting light rays emitted out from an OLED luminous sheet after uniform scattering by covering a diffuse reflection layer on a bottom plate, improving the luminous efficiency, andimproving the great-visual-angle brightness. The OLED luminous device is mainly characterized by comprising the bottom plate and the OLED luminous sheet, wherein the diffuse reflection layer is arranged on the bottom plate; the OLED luminous sheet is laid on the diffuse reflection layer; and the diffuse reflection layer is used for performing diffuse reflection on the light rays emitted by the OLED luminous sheet to the bottom plate. The OLED luminous device and the automobile rear lamp are mainly used for illumination.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to an OLED light emitting device and a car tail light. Background technique [0002] With the continuous development of electroluminescence technology, light sources using the principle of electroluminescence, such as organic light-emitting diodes (Organic Light-Emitting Diode, OLED), are more and more widely used. Among them, OLED has self-luminescence, wide viewing angle, almost infinite The advantages of high contrast, low power consumption, and high response speed have received widespread attention. [0003] In traditional light-emitting devices that use OLEDs as light sources, OLEDs are simply laid on a preset fixed surface. However, due to the characteristics of OLEDs that emit light by themselves, and the light propagates in all directions at the same time, the traditional application of OLEDs ignores the direction of OLED light. Adjustment, resulting in uneven li...
