Patent Number: 7,712,935

Title: Lamp unit

Abstract: A lamp unit is provided. The lamp unit includes a light emitting element disposed on an optical axis so as to face in a direction substantially orthogonal to the optical axis, a first reflector facing the light emitting element to forwardly reflect light from the light emitting element, and a direct light control member disposed in front of the light emitting element for controlling direct light directed toward a region in front of the first reflector from the light emitting element without being incident on the first reflector. The direct light control member includes a first lens portion which deflects a first portion of the direct light in a direction approaching the optical axis, and an extended portion extending from the first lens portion. The extended portion controls a second portion of the direct light differently from the first lens portion.
