Patent ID: 7045375

Claim:
A method of producing a white-light emitting source, the white light comprising at least a first color component with a first wavelength, a second color component with a second wavelength, and a third color component with a third wavelength, the first wavelength shorter than the second wavelength, the second wavelength shorter than the third wavelength, said method comprising the steps of: providing at least one first light emitting device, the first light emitting device comprising a first light source for emitting the first color component, and a second light source for emitting a part of the third color component responsive to the first color component; disposing at least one second light emitting device adjacent to the first light emitting device, the second light emitting device having a first light source for emitting the second color component, and a second light source for emitting a further part of the third color component responsive to the second color component; and combining the first color component and said part of the third color component emitted by the first light emitting device to the second color component and said further part of the third color component so as to produce said white light.
