INCANDESCENT EMITTING DEVICE AND LUMINAIRE |
摘要 |
<P>PROBLEM TO BE SOLVED: To improve the color rendering property of an incandescent emitting device provided with a luminous and a wavelength converting material. <P>SOLUTION: The incandescent emitting device includes the wavelength converting material which absorbs at least parts of light source and light emitted from the light source to emit light of different wavelengths, and emits incandescent light containing the light emitted from the wavelength converting material. The maximum emission intensity in a wavelength range of emission spectrum of incandescent light of 500-650 nm is set to ≤150% of the minimum emission intensity in the same wavelength range. <P>COPYRIGHT: (C)2007,JPO&INPIT |
