Illumination device and vehicle headlight

摘要

In a head lamp 1, relative positions of a laser light guide path in a tapered light guide section 20 and a parabolic mirror 5 are fixed. An optical fiber 10 and the tapered light guide section 20 are each provided so as to have a receiving end part where laser light is received and an emitting end part where laser light is emitted. The emitting end part of the optical fiber 10 is located near the receiving end part of the tapered light guide section 20.

主权项

1. An illumination device, comprising:
a first light guide section and a second light guide section, which guide emission light emitted from a light source; a light conversion section converting the emission light which has been guided by the first and second light guide sections to illumination light; and a light distribution section controlling distribution of the illumination light thus converted, the first light guide section having flexibility and guiding the emission light to the second light guide section, a light guide path for the emission light in the second light guide section and the light distribution section being provided so as to be fixed relative to each other, the first and second light guide sections each having (i) a receiving end part where emission light is received and (ii) an emitting end part where emission light is emitted, the emitting end part of the first light guide section being provided near the receiving end part of the second light guide section, the light conversion section being provided on a metallic member, and the light conversion section being irradiated with the emission light at one surface thereof opposite to the metallic member.
