Patent ID: 7417260

Claim:
A light emitting device for emitting a multiple-chromatic light, comprising: a cup-shaped base having a top open end; a transparent cover covering said top open end of said cup-shaped base; a first light emitting diode (LED) that is mounted in said cup-shaped base and that emits a first primary light in a first primary wavelength range when activated; a second light emitting diode (LED) that is mounted in said cup-shaped base and that emits a second primary light in a second primary wavelength range when activated, said second primary wavelength range differing from said first primary wavelength range; a semiconductor first photon-recycling member bonded to the cover and associated with said first LED in such a manner to convert a portion of the first primary light into a first secondary light in a first secondary wavelength range through photon-recycling mechanism and to permit the remainder of the first primary light to pass therethrough, said first photon-recycling member being aligned with the first LED; and a semiconductor second photon-recycling member bonded to the cover and associated with said second LED in such a manner to convert a portion of the second primary light into a second secondary light in a second secondary wavelength range through photon-recycling mechanism and to permit the remainder of the second primary light to pass therethrough, said second photon-recycling member being aligned with the second LED; wherein said first secondary wavelength range is different from said first and second primary wavelength ranges, thereby enabling said light emitting device to emit the multiple-chromatic light.
