Abstract
An obstacle detecting device includes: a light source having both LED units each for emitting visible light and an infrared light unit for emitting infrared light; and a rotating reflector configured to be rotated in one direction around a rotational shaft while reflecting the visible light and the infrared light emitted from the light source. The rotating reflector is configured, by its rotating movement: to emit the visible light from each of the LED units as an irradiation beam such that a first light distribution pattern is formed by scanning with the irradiation beam; and to emit the infrared light from the infrared light unit as an irradiation beam such that a second light distribution pattern is formed by scanning with the irradiation beam.
Claims4
An obstacle detecting device comprising:
- a light source including both a first light emitting element for emitting visible light and a second light emitting element for emitting infrared light;
- and
- a rotating reflector configured to be rotated in one direction around a rotational shaft while reflecting the visible light and the infrared light emitted from the light source, wherein
- the rotating reflector is configured, by its rotating movement:
- to emit the visible light from the first light emitting element as an irradiation beam such that a first light distribution pattern is formed by scanning with the irradiation beam;
- and to emit the infrared light from the second light emitting element as an irradiation beam such that a second light distribution pattern is formed by scanning with the irradiation beam, and wherein
- the rotational shaft is provided to be approximately parallel to a scanning plane formed by continuously connecting the trajectories of the light of the irradiation beam that scans in the horizontal direction by the rotation of the rotating reflector.
