LED provides monochromatic light with a large half-width. Since the energy gap of the semiconductor decreases with the increase of temperature, the peak wavelength it emits increases with the increase of temperature, that is, the spectrum red shifts, and the temperature coefficient is +2~3A/. The LED luminous brightness L is approximately proportional to the forward Поточний . У міру збільшення струму світла яскравість також збільшується приблизно ..
