LED lights will age rapidly at high temperatures for a long time

A piece of white dried bean curd, after the positive and negative current is connected, the temperature on one side can quickly drop below 0℃ within 90 seconds. If this piece of dried bean curd is used to cool down LED street lamps, it can ensure that the working temperature of the lamp bead is below 60℃, completely solve the problem of LED light attenuation and prolong the service life of street lamps. As of yesterday, the number of patent applications for high-power LED street lamps produced by Suzhou Weiyuan New Materials Co. , Ltd. in Tongli Town, Wujiang, has reached 18, of which 9 are invention patents. This is a seemingly ordinary white semiconductor chip with the same size and thickness as dried bean curd. The difference is that one side of the chip is connected with two wires, one red and one black. If the two wires are connected to the positive and negative DC power supply, the chip that was originally in the normal temperature state will quickly cool down and the surface will condense into water droplets. The other side will be hot and even hot. This chip is called an integrated temperature balancer and is the core of heat dissipation for LED street lamps. Gu Wei, chairman of Weiyuan new materials, said that when LED lights are lit, a high temperature of 90℃ will be generated. The traditional LED street lamp production process is to install the lamp bead on an aluminum substrate and cool the lamp bead by means of heat conduction, however, due to environmental constraints, the cooling effect is not obvious. LED lights will age rapidly at high temperatures for a long time, resulting in large light decay. In order to enhance the heat dissipation effect, many LED lamp manufacturers use their brains to increase the heat dissipation area, making the aluminum radiator larger and larger. At present, a 220W high-power LED street lamp commonly used in the market weighs 18 kg and consumes a lot of mineral resources. The semiconductor electronic chip developed by Weiyuan new material changes the traditional passive heat dissipation into active heat dissipation. After the lamp bead of 90℃ contacts the cold surface of the chip, the cold and hot energy can be quickly neutralized, keep the working temperature of the lamp bead below 60 °c at all times. After 1. After 30 thousand hours of continuous testing, the light attenuation of LED lamps below 60℃ is 0. Why does a chip with a large amount of tofu become cold after being powered on? Gu Wei said that the key lies in many rice-sized semiconductor particles inside the LED chip. These particles are sintered by rare earth and more than 10 kinds of rare metals. The raw materials are very common in China, but the formula has been developed for 7 years. There is also a heat pump radiator and a uniform temperature aluminum substrate used together with the chip. When making LED street lamps, firstly, the LED lamps are installed on the high conduction uniform temperature aluminum substrate through the grid matrix circuit, and then the number of chips and radiators is determined according to the power of the LED lamps, to ensure that the temperature of the lamp board is always controlled within 60℃, the light attenuation problem of high-power LED is completely solved, and the service life is prolonged. At the same time street lamp carat total weight can reduce 70 above. Xia Yaoding, executive vice president of Weiyuan new materials, said that together with invention patents and utility model patents, the high-power LED street lamps they produce have 18 patents. At the same time, these core technology products for heat dissipation can be applied to compressor-free household air conditioners, high-efficiency automotive LED anti-fog lamps, notebook CPU heat dissipation, etc. with a slight improvement, bringing revolutionary breakthroughs to traditional electronic products.
