Guangmai LED mainly produces LED SKD Parts LED circuit boards for street light with the following specifications:
Domestically, the state-owned factory No. 704 began to develop aluminum substrates in the late 1980s, and commercial products were soon launched. At that time, it was mainly used in STK series power amplifier hybrid integrated circuits, motorcycles and automotive electronics, and contributed to the development of related industries. After nearly 20 years of development, the development of my country's aluminum substrate has entered a rapid development track. According to relevant statistics, there are currently close to 200,000 domestic enterprises engaged in the production of aluminum substrates.
In the past two years, high-power LED lighting has followed the trend of energy conservation and environmental protection, and has achieved rapid development, which has injected a strong impetus into the rapid growth of aluminum substrates. For a while, a wave of aluminum substrates has been set off across the country. Here, we will focus on analyzing the condition of the aluminum substrate used in the LED.
In fact, LED has been used in the market for a long time, and its application areas are mainly concentrated in PDAs, mobile phones, and other consumer electronics markets. The lifespan of these products is relatively short, and the lifespan of the LEDs is not a major issue, because these products are scrapped or obsolete before the lifespan of the LEDs expires. With the continuous advancement of LED design and process technology, the brightness of LEDs is continuously improved to compete with incandescent lamps, fluorescent lamps, and even halogen lamps. Like most electronic devices, heat is also the biggest threat to LEDs. Although most people think that LED does not generate heat, in fact, relative to its size, the heat generated by LED is very large. Heat not only affects the brightness of the LED, but also changes the color of the light, which will eventually lead to the failure of the LED. Therefore, preventing the accumulation of LED heat is becoming more and more important. The key to maintaining the long-term continuous high brightness of the LED is the use of the most advanced heat management materials, and the use of high thermal conductivity aluminum substrate is one of the elements.
In a typical LED structure (see Figure 2), the heat generated by the LED is conducted to the metal substrate through the insulating layer, and then to the heat sink through the thermal interface material, so that most of the heat generated by the LED can be passed through the convection Way to diffuse into the surrounding air. However, most aluminum substrate insulation layers have little or no thermal conductivity, so that heat cannot be conducted from the LED to the heat sink (metal substrate), and the entire heat dissipation channel cannot be unblocked. In this way, the heat accumulation of the LED will quickly cause the LED to fail. The aluminum substrate with a high thermal conductivity insulating layer solves this problem well. In order to ensure the lowest operating temperature of the LED, the brightest brightness, and the longest service life. Therefore, choosing an aluminum substrate with high thermal conductivity is very important for LEDs.
