Question:yixiaojie
sed 2W of power Shi, LED chip of junction temperature than welding points high 18K, even printed circuit plate temperature rose to 500C, junction temperature at most only 700C around; phase than Xia past hot impedance once reduced words, LED chip of junction temperature on will was printed circuit plate temperature of effect, so comes required managed to reduced LED chip of temperature, in other words reduced LED chip to welding points of hot impedance, Can effectively reduce the burden of LED c
