Title:
VEHICULAR LAMP USING SEMICONDUCTOR LIGHT-EMITTING DIODES
Document Type and Number:
WIPO Patent Application WO/2020/080570
Kind Code:
A1
Abstract:
The present invention provides a vehicular lamp comprising: a substrate; a plurality of first semiconductor light-emitting diodes which are arranged on the substrate in a row and which emit light of a predetermined color; a plurality of second semiconductor light-emitting diodes which are arranged on the substrate in a row parallel to the first semiconductor light-emitting diodes and which emit light of a color different from that of the first semiconductor light-emitting diodes; a phosphor layer which is arranged to overlap the first semiconductor light-emitting diodes and the second semiconductor light-emitting diodes and which converts the wavelength of light; and an optical unit which is provided with a light-incident surface and which reflects or diffracts light incident onto the light-incident surface, the optical unit being arranged such that at least part of the light-incident surface overlaps the phosphor layer, wherein the phosphor layer selectively converts the wavelength of only light emitted from the first semiconductor light-emitting diodes or the second semiconductor light-emitting diodes.
