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. Brightness is also associated with environmental temperature, when the ambient temperature is high, recombination efficiency decreased light intensity decreases.
