Title:
LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/034205
Kind Code:
A1
Abstract:
The present invention is equipped with: a first LED (51) for emitting light of a first color; a second LED (52) for emitting light of a second color, the wavelength of which is different from that of the first color; a first heat transfer section (53) interposed between the first LED (51) and a first heat dissipating section (55a), which dissipates heat generated in the first LED (51); and a second heat transfer section (54) interposed between the second LED (52) and a second heat dissipating section (55b), which dissipates heat generated in the second LED (52). The heat dissipation capacity of the first heat dissipation section (55a) and the first heat transfer section (53) and the heat dissipation capacity of the second heat dissipation section (55b) and the second heat transfer section (54) are set on the basis of the ratio between the lighting times of the first LED (51) and the second LED (52) and/or the ratio between the amount of power supplied for the first LED (51) and the second LED (52).
