led devices, such as high-power led, gan-based led designers in carrying silicon flip chip, the design esd protection diodes , then not only as a silicon subsate carrying gan, but also play a role in esd protection, making the device using this chip package esds reach several thousand volts. its advantage is resistance to esd items directly tigang yin ability to simplify the packaging process of production and installation of static device protection; disadvantage of increased costs, increased volume, complexity of the chip production process and the need for the specialized production facilities, it is suitable for high value of the led devices.vinyl signs (http://www.junxiaoguangchang.com/) 
the researchers say they developed advanced laser coating technology helps components, radar or thermal power eleconic components can be used in high-performance computers, military aerospace, elecic vehicles or renewable energy systems. the researchers pointed out that nano-zinc oxide coating allows the thermal coefficient of copper to enhance the cooling times as mand system technology, and currently still studying, but apparently because of the high density of nucleation sites (nucleation sites) and a better capillarity (capillary pumping action), leading to such maix for each unit of surface area to improve heat ansfer efficiency. if the use of micro channel architecture (microchael architectures) on the mandatory application of the liquid cooling system.led scrolling sign (http://www.junxiaoguangchang.com/)
all reverse comparator connected to the output voltage nodes. according to the input / output voltage ratio, the output of the comparator to provide a 3-bit word with the gain conol circuit, gain conol circuit is used to select the smallest gain g, so you get the desired voltage conversion. however, in white led applications, select the correct gain g is not only based on the input and output voltage. figure 5: the switched capacitor white led driver can be used for the four led figure 5 is to enhance the use of adaptive voltage charge pump led drivers, and a bit of a gain of up to five times. connect the input of charge pump vin pin, the output vout pin is connected.lawn signs (http://www.junxiaoguangchang.com/)
