  • Three wavelength LED structure
    Publication number: 20070108455
    Abstract: A three wavelength light emitting diode (LED) structure utilizes a blue light LED chip and a green light LED chip as light sources, and a red fluorescent layer is used as a light transition layer. By adjusting the number of the blue light LED chip and the green light LED chip and the dosage of the chemical substances in the red fluorescent layer, the present invention can produce a white light LED which is adjustable in color temperature, a neutral color LED whose color is changeable, or can produce a LED whose light color changes with time.
