Title:
VEHICULAR LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2017191638
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture which can cool a semiconductor light-emitting element of a light source unit efficiently while achieving reduction in weight and cost by simplification of the structure and reduction in the number of components.SOLUTION: A vehicular lighting fixture is constituted by: a lamp body unit 2 which includes a lamp module 8 having a lens 16 for light distribution control and a light conversion element 15 for converting the light into a specific wavelength; and a light source unit 3 which includes a light source part 3A separately provided from the lamp body unit 2, and including a semiconductor light-emitting element which serves as a light source, and a heat sink (heat radiation part) 3B for radiating heat generating in the light source part 3A. The lamp body unit 2 and the light source unit 3 are connected by an optical fiber (light propagation means) 4. The heat sink 3B of the light source unit 3 is arranged in a ventilation flue connected to an air conditioning unit 25 of a vehicle 1 (in an outside air duct 27 in Figure).SELECTED DRAWING: Figure 3
