Abstract

The invention discloses a light-emitting diode and a preparation method thereof. The light-emitting diode is composed of a pedestal, a molded resin lens, a metal nano-material coating layer, a light-emitting layer, an LED chip, an anode pin, a cathode pin, a fixed protection base, a fixation mechanism and a buffer protection mechanism. The LED chip is fixed at the center of the top of the pedestalby a screw; the light-emitting layer is installed at the top of the LED chip; the metal nano-material coating layer is arranged at the top of the light-emitting layer; and the molded resin lens coating the metal nano-material coating layer, the light-emitting layer, and the LED chip is arranged at the top of the pedestal. The buffer protection mechanism consists of a pin protection hole, a buffergroove, a fixed block, a moving rod, an annular fixed sleeve, a first rotating rod, a damping spring, a second rotating rod, a second reset spring, a chute, a moving slot, and a second clamp plate. According to the light-emitting diode, the anode pin and the cathode pin are buffered and protected well.

Description

technical field [0001] The invention relates to the technical field of light emitting diodes, in particular to a light emitting diode and a preparation method thereof. Background technique [0002] Light Emitting Diode (Light Emitting Diode) is a light emitting device that emits ultraviolet, visible or infrared light when a forward voltage is applied across a semiconductor p-n junction. It is a new generation of solid light source. Because of its small size, long life, low driving voltage, fast response, shock resistance, heat resistance and other characteristics, since the first light-emitting diode came out in 1964, people have not stopped the pace of research and development. With the development of light-emitting materials The development and improvement of semiconductor manufacturing process, as well as the introduction of distributed Bragg emission structure, optical microcavity and quantum well structure in the process of chip growth, have continuously improved the ef...

Problems solved by technology

[0003] However, the general light-emitting diodes are not equipped with a protection mechanism for the anode pin and the cathode pin during transportation, so that the light-emitting diodes are squeezed during transportation, resulting in broken legs. In view of this defect, we design a A light-emitting diode to solve the problem of pin protection when the light-emitting diode is transported
