Magic white bean curd to cool the LED street lamp

Technical personnel to the comprehensive temperature balancer

A piece of white "bean curd", when the positive and negative current is turned on, the temperature can be reduced to 0 DEG C in the following 90 seconds. If this piece of "tofu" is used for LED lamp cooling, can ensure the lamp working temperature of 60 DEG C, completely solve the problem of LED decay, and improve the service life of the lamp. As of yesterday, located in the town of Wujiang, Suzhou Wei source of new materials Co., Ltd. production of high-power LED street lamp, patent applications reached 18, of which the invention patent for the invention of the 9.

This is a seemingly ordinary white semiconductor chips, the size, thickness and tofu quite. The only difference is that the chip is connected with one side, one red and one black two wires. If the two wires through the positive and negative DC power supply, the original in the normal state of the chip, one side will quickly cool, the surface condenses into water. The other side will heat, and even hot.

This chip is called the integrated temperature balancer, is the core of the LED street lighting. "Great source of new materials chairman Gu Wei introduced, LED lamp is lit, will produce high temperature of 90 DEG C, the traditional LED lamp production process that the lamp installed on the aluminum substrate, by heat conduction to the lamp cooling, but are restricted by the environment, the cooling effect is not obvious.

The LED lamp is in high temperature for long time will produce a rapid aging, decay.

In order to enhance the effect of heat dissipation, a lot of LED lamp manufacturers to increase the heat area on the brain, making aluminum radiator volume is growing. Currently on the market commonly used a 220W high-power LED street lamp, the weight of 18 kg, a large number of mineral resources.

The great source of new materials research and development of semiconductor chip, the traditional passive cooling into active cooling, 90 C beads exposed to cold chip surface, and can quickly and always maintain the working temperature of the lamp bulb below 60 DEG C. "After 13 thousand hours of continuous testing, the LED light below the temperature of 60 degrees is reduced to 0. "

A piece of dried bean curd big chip, why power will become cold after the side? Gu Wei said that the key lies in the chip inside a lot of grain size of semiconductor particles. These particles from rare earth and more than 10 kinds of rare metal sintering ratio, raw materials in the country is very common, but the formula they developed for 7 years.

Supporting the use of the chip, and a heat radiator and a temperature of aluminum substrate. In the production of LED lights, LED lights will be first installed in high temperature aluminum substrate conduction through the grid matrix circuit, and then determine the number of chips and radiator according to the size of the LED lamp power, ensure the lamp plate temperature is always controlled within 60 DEG C, completely solve the problem of high power LED light, improving the service life. At the same time, the total weight of street lamps can be reduced by more than 70%.

Wei new material deputy general Xia Yaoding introduced, together with the invention patent and utility model patents, high power LED lights they produce has 18 patents. At the same time, the core technology products for cooling as long as a little improvement, can be applied to compressor type household air conditioners, anti fog, efficient automobile LED CPU notebook cooling, bring a revolutionary breakthrough for traditional electronic products.
