Vehicular lamp
A vehicular lamp includes a light source, a reflector, and a projection lens. The vehicular lamp is configured to radiate, toward front of the lamp via the projection lens, light from the light source, the light being reflected by the reflector. A reflective surface of the reflector includes a reflective region configured to illuminate a short-distance road surface within 5 m in front of the lamp. A light diffusing treatment for diffusing and reflecting emitted light from the light source is applied to the reflective region.
1. A vehicular lamp comprising:
a light source;
a reflector; and
a projection lens,
wherein the vehicular lamp is configured to radiate, toward front of the vehicular lamp via the projection lens, light from the light source, the light being reflected by the reflector,
a reflective surface of the reflector includes a reflective region configured to illuminate a short-distance road surface within 5 m in front of the vehicular lamp, and
a light diffusing treatment for diffusing and reflecting emitted light from the light source is applied to the reflective region,
wherein the light source includes a light emitting element mounted on a substrate,
the substrate is arranged in a state where a light emitting surface of the light emitting element is inclined obliquely upward toward the front of the vehicular lamp, and
the reflector is arranged to cover the light emitting element from above,
wherein the light emitting element includes:
a first light emitting element configured to be lighted during low-beam irradiation; and
a second light emitting element configured to be additionally lighted during high-beam irradiation,
the second light emitting element is arranged at a position away from the first light emitting element to a front side of the vehicular lamp, and
the reflector includes:
a first reflector configured to reflect, toward the projection lens, emitted light from the first light emitting element; and
a second reflector configured to reflect, toward the projection lens, emitted light from the second light emitting element,
the second reflector is arranged at a position between the first light emitting element and the second light emitting element, and
the reflective region is formed on a reflective surface of the first reflector.
2. The vehicular lamp according to claim 1 ,
wherein the first reflector and the second reflector are integrally formed.
3. The vehicular lamp according to claim 1 ,
wherein the first light emitting element and the second light emitting element are mounted on a common substrate.
4. The vehicular lamp according to claim 1 ,
wherein the vehicular lamp is configured as a headlight for a two-wheel vehicle.
