Abstract

The invention discloses a heat-electricity-separated LED. The heat-electricity-separated LED comprises an LED bracket and an LED chip. The LED chip comprises an LED main body; a heat sink is arranged at the bottom of the LED main body; electrodes are arranged at the two sides of the LED main body; a concave bowl-shaped groove is formed in the upper surface of the LED bracket; a radiator is arranged at the bottom of the LED bracket; a heat conducting block connected with the radiator is arranged at the bottom face of the bowl-shaped groove; two electrode contacts are further arranged at the bottom face of the bowl-shaped groove; insulating layers separating the heat conducting block from the two electrode contacts are arranged in the LED bracket; the LED chip is arranged at the bottom face of the bowl-shaped groove; the heat sink is located at the top of the heat conducting block and makes contact with the heat conducting block; and the electrodes at the two sides of the LED main body are connected with the two electrode contacts correspondingly. The heat-electricity-separated LED is good in heat dispersion performance, improves the using reliability of the LED and prolongs the service life of the LED.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a thermoelectric separation LED. Background technique [0002] With the continuous development of semiconductors, in recent years, LEDs are being widely used in various industries due to their advantages of environmental protection, long life, and high brightness. The requirements for reliability and service life of LEDs are getting higher and higher, making Higher requirements are put forward for the heat dissipation treatment of LEDs, especially for high-power LEDs. The traditional LED heat dissipation method is to solder the LED on the circuit board, and then place the board on the heat sink. A layer of circuit board is sandwiched between the LED and the heat sink. The heat transfer effect of the board is not good, resulting in poor heat dissipation of the LED. . Contents of the invention [0003] The purpose of the present invention is to overcome the technical problem of po...
