Ultrathin ultraviolet LED chip capable of emitting light efficiently

Abstract

The invention discloses an ultra-thin ultraviolet LED chip capable of emitting light efficiently. The ultra-thin ultraviolet LED chip comprises a loading bottom plate, a loading cavity is pre-formed in the loading bottom plate, a butt joint hole is pre-formed in the upper end of the outer side of the loading bottom plate, and a first-stage square groove is pre-formed in the middle of the loading cavity. And a micro circuit substrate is fixedly installed at the lower end of the interior of the loading cavity, a secondary adaptive contact layer is fixedly installed at the other side of the upper end of the exterior of the auxiliary light-emitting layer, a transparent conductive layer is fixedly connected to the upper end of the exterior of the secondary adaptive contact layer, and a negative electrode metal connecting piece is fixedly installed at the upper end of the exterior of the transparent conductive layer. According to the ultra-thin ultraviolet LED chip capable of emitting light efficiently, due to the arrangement of the cooling fins and the auxiliary cooling grooves, the internal cooling effect of the whole chip in normal use and work is improved to the maximum extent, and the service life of the whole chip can be prolonged. The ultraviolet light-emitting layer plate is additionally arranged, the overall working efficiency is effectively enhanced on the basis that the overall LED light-emitting effect is achieved.

Description

technical field [0001] The invention relates to the technical field of LED chips, in particular to an ultra-thin ultraviolet LED chip with high-efficiency light emission. Background technique [0002] The LED chip is a solid-state semiconductor device. The heart of the LED is a semiconductor wafer. One end of the wafer is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire wafer is encapsulated by epoxy resin. LED Chips are the core components in modern LED products. [0003] The overall structure of the existing LED chip in the existing market has a large thickness and does not have good heat dissipation performance. In the long-term use work, it is easy to cause internal overheating due to the limitation of its own internal structure and cause internal components to fail. Damage or failure shortens its own service life, and the overall light output performance is relatively averag...
