Abstract:
A vehicular lamp has a light-emitting element facing a forward direction of the lamp, and a translucent member that covers the light-emitting element from a front side. The translucent member has a center region located forward of the light-emitting element that serves as a lens-like direct light control portion. The translucent member has a peripheral region surrounding the center region that serves as a reflecting light control portion in which light emitted from the light-emitting element and incident on the translucent member is internally reflected forward by a rear surface of the translucent member and emitted forward from a front surface of the translucent member. The direct light control portion is configured such that light emitted from the direct light control portion has a light intensity distribution in which light intensity is highest in a direction at a first required angle from the forward direction of the lamp.
