Provide is half the width of a lot of monochromatic light LED, semiconductor energy gap decreases as temperatures rise, so the peak wavelength emitted by it and increases with temperature, the spectral red shifts, temperature coefficient is +2~3A/. LED luminance l is proportional to forward current. Current increases, the brightness also increase.
Using thermal film for LED spotlight heat sink thermal conductivity, not good heat dissipation.
Foshan South in semiconductor lighting research developed a high-power LED thermal problems successfully resolved using liquid cooling method, small LED lights cooling problems, has made a historic breakthrough, difficult questions contribute to cool the LED spotlights.
Heat pipe cooling
LED spotlight heat sink using heat pipe, as well as computer CPU heat, which gets bigger, bulkier.
