Description

technical field [0001] The invention belongs to the technical field of LED light-emitting elements, in particular to an LED light-emitting element with an integrated drive circuit. Background technique [0002] The English of the light-emitting diode is Light Emitting Diode (LED). Its basic structure is a piece of light-emitting semiconductor material, placed on a leaded support, and then sealed with epoxy resin around it. When it is in the forward working state (ie A positive voltage is applied to both ends), and the current flows from the anode to the cathode of the LED, and the semiconductor material will emit light, and the intensity of the light is related to the magnitude of the current. For many years, LED has been playing an important role in the field of flat panel display, and relying on its unique advantages of high brightness, high strength, long life, splicing, convenience and flexibility, it can be displayed indoors and outdoors in large areas, especially in sp...
