Title:
LAMP FOR VEHICLE AND LIGHT EMITTING DEVICE
Document Type and Number:
Japanese Patent JP2023108396
Kind Code:
A
Abstract:
To provide a lamp or the like for a vehicle which can seamlessly change a luminescent color of a light source which is packaged while including a semiconductor light emitting element and a wavelength conversion member.SOLUTION: A lamp 1 for a vehicle comprises: a light source which is packaged while including at least one semiconductor light emitting element for emitting first light, and a wavelength conversion member excited by the other partial light out of the first light, and emitting second light having a wavelength which is different from that of the first light, being a first light source 10 for emitting mixed light which is obtained by mixing the first light permeating the wavelength conversion member and the second light emitted by the wavelength conversion member; first optical systems 60, 61 forming a light distribution pattern for the lamp for the vehicle by controlling the mixed light which is emitted by the first light source; and at least one second light source 20 for emitting third light which radiates the wavelength conversion member, and excites the wavelength conversion member.SELECTED DRAWING: Figure 3
