An LED device based on a 3D printing process

Abstract

The application relates to an LED device formed based on a 3D printing process, which comprises a pin layer, a circuit connection layer and an electrode control layer which are formed by printing layer by layer from bottom to top by a 3D printer; the pin layer comprises a first epoxy resin layer and a plurality of pin electrodes which are connected to each other, and the pin electrodes are distributed at four corner positions of the first epoxy resin layer; the circuit connection layer comprises a second epoxy resin layer and a plurality of switching conductors which are connected to each other, one end of each of the switching conductors is connected to each of the pin electrodes; the electrode control layer comprises a third epoxy resin layer and a metal pad which are connected to each other, the metal pad comprises a common electrode pad and a plurality of non-common electrode pads; the other end of each of the switching conductors is extended and connected to the corresponding common electrode pad and non-common electrode pad or is bent and extended and connected. The pin layer, the circuit connection layer and the electrode control layer of the application are formed by one-time printing, the deviation between single LED devices is reduced, and the light emitting quality is improved.
