Question:admin
that the above mentioned structure of the LED chip to the welding point of the thermal impedance can reduce the 9K / W, is about a traditional LED 1 / 6, after the LED package to give to 2W electricity, LED chips with high temperature than the welding point of 18K, even if the printed circuit board temperature rise rose 50 ℃, with the temperature at most only about 70 ℃; contrast the past to reduce the thermal resistance, then once, LED chip with temperature will be subject to the printed cir
