Light emitting device

Abstract

A light emitting device comprises a plurality of light emitting modules which are connected with one another. Each light emitting module comprises a substrate for power supply and conduction, an action unit and an electrode unit, wherein the action unit is arranged on the substrate and generates light through the photoelectric effect in the power supply process, and the electrode unit comprises a transparent electrode arranged on the action unit. Part of the area of the substrate of any light emitting module is arranged on the electrode unit of another adjacent light emitting module in an overlapped mode to form electric connection, and the light emitting modules are overlapped and electrically connected with one another to form the light emitting device. Not only can the overall light emitting uniformity of the light emitting device be effectively improved, but also the light emitting device is more suitable as a large-area light emitting source.

Description

technical field [0001] The invention relates to a light emitting device, in particular to a light emitting device suitable for use as a large-area light source. Background technique [0002] refer to figure 1 , if the current light-emitting device 1 needs to emit light in a large area, for example, as a backlight source, it is usually necessary to arrange a plurality of light-emitting modules 11 in an orderly manner, and then respectively mark each light-emitting module 11 with gold wires, Solder, or silver glue, etc. will be connected to each other and electrically connected ( figure 1 In this way, when the outside supplies power to these light-emitting modules 11, these light-emitting modules 11 can emit light outwards as a whole, and a large-area light-emitting device 1 can be obtained. [0003] Depend on figure 1 It can be seen that although a large-area light-emitting source can be produced by using a plurality of light-emitting modules 11 to be electrically connecte...

AI Technical Summary

Problems solved by technology

[0003] Depend on figure 1 It can be seen that although a large-area light-emitting source can be produced by using a plurality of light-emitting modules 11 to be electrically connected to each other, when these light-emitting modules 11 are arranged, there must be a gap 13 between two adjacent light-emitting modules 11. The gaps 13 cannot generate light, so when the light emitting device 1 emits light, these gaps 13 are all dark places that do not emit light, causing dark spots to be generated when the components emit light, and the uniformity of the overall light emission is not good; Because the gold wires 12 on the top surface of these light emitting modules 11, or the solders that electrically connect these light emitting modules 11 to each other are made of opaque materials, therefore, the light emitted by these light emitting modules 11 is blocked The opaque material distributed on the top surface of these light-emitting modules 11 is shielded, so that the light-emitting device 1 also has the disadvantage of low luminous brightness.
