Abstract :
A trichromatic phosphor-free white light-emitting diode has been implemented by using adhesive bonding scheme. As 25mA and 60mA was injected into the red and blue-green LED chips at room temperature respectively, white light emission could be observed with CIE chromaticity coordinates (0.3330,0.3241), correlated color temperature Tc=5467K and optical power φe=2.223mW.
