nsity and the die structure, light output, encapsulated lens material and the shape used. The use of a tapered resin lens, can focus light to the LED in the axial direction, the corresponding small angle; If the top of the resin lens is round or flat type, the corresponding angle will increase. In general, LEDs emission wavelength with temperature change is 0.2-0.3nm / ℃, spectral width increases, the degree of bright colors.
In addition, when forward current flows through the pn junction, the
