Light emitting device, lighting system, headlight, and vehicle

摘要

A light emitting device which includes at least one of a laser light source (1), wiring (9), a lens for excitation (2), a luminous body (4), a laser cut filter (6), a half parabolic mirror (5P), and a base (5h), in which a part of the wiring (9) is installed at a portion in which a breakage easily occurs due to at least one deformation of the laser light source (1), the lens for excitation (2), the luminous body (4), the laser cut filter (6), the half parabolic mirror (5P), and the base (5h), or a change in an installation position thereof.

主权项

1. A light emitting device comprising:
a laser light source which includes at least one semiconductor laser; a wiring that supplies a current to the laser light source; and at least two optical members including a first optical member and a second optical member which change a state of laser light which is emitted from the laser light source, wherein a portion of the wiring is installed at a position in which a breakage of the wiring easily occurs due to at least any one deformation of the laser light source, the first optical member, and the second optical member, or a change in an installation position thereof, and in a portion of the wiring, at least two paths are present, including a path which is connected to a portion of the first optical member at which the breakage easily occurs and a path which is connected to a portion of the second optical member at which the breakage easily occurs.
