An integrated high-power led thermoelectric separation bracket

Abstract

The invention discloses an integrated high-power LED thermoelectric separation bracket, which includes a ceramic substrate, a heat conduction plate, a heat insulation plate and a circulating cooling water tank. A packaging seat is embedded on the top of the ceramic substrate, and an LED chip is packaged in the packaging seat. The bottom is provided with a number of heat conduction sheets, the middle position of the heat conduction sheet and the bottom end of the ceramic substrate are provided with a heat shield, and the bottom of the heat shield is provided with a circulating cooling water tank; between the circulating cooling water tank and the heat shield and between the heat shield and the heat shield The ceramic substrates are all connected by screws, and the two sides of the ceramic substrates are symmetrically provided with first clamping blocks. Beneficial effects: reasonable structural design, good heat dissipation effect, higher luminous efficiency of LED chips, improved service life of products, cost savings, convenient replacement of damaged LED chips through modular design, and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an integrated high-power LED thermoelectric separation bracket. Background technique [0002] LED is called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, and small size. It is widely used in various indications, displays, decorations, backlights, general lighting, and urban night scenes. According to different functions, it can be divided into five categories: information display, signal lights, vehicle lamps, LCD backlight, and general lighting. [0003] Due to the characteristics of high brightness, rich colors, low power consumption and long life of LEDs, LEDs are widely used in the field of automotive lighting. LED car lights are becoming more and more popular. At present, only 20-30% of the electrical energy of LED chips is converted into light energy, and the rest of the electrica...

Problems solved by technology

LED car lights are becoming more and more popular. At present, only 20-30% of the electrical energy of LED chips is converted into light energy, and the rest of the electrical energy is converted into heat energy. High chip temperature reduces light efficiency, chip life decay, color rendering and other performance changes , In addition, car LED lights generally have high power and long lighting time, especially when driving on the highway at night, high-power LED lights emit a lot of heat after working for a long time, poor heat dissipation or untimely heat dissipation can lead to LED car lights. The lighting effect of the lamp is not good, which leads to the generation of potential safety hazards, and the traditional LED lamp, the integral structure of the LED chip and the lamp group, needs to be replaced as a whole after damage, which increases the maintenance cost. The traditional heat dissipation method of automobile lamps is generally radiation heat dissipation, natural cooling
