车辆用灯具
摘要：
本发明提供一种车辆用灯具，其具有具备直射光控制部及反射光控制部的透光部件，在该车辆用灯具中，能够在以灯具正面方向为中心的一定的角度范围内，以比较均匀的亮度进行光照射。将构成透光部件的中心区域的透镜状的直射光控制部构成为，其出射光的光度分布(Ah、Av)在从灯具正面方向远离第1设定角度(αh、αv)的方向上光度(I)最高。另一方面，将构成透光部件的周边区域的反射光控制部构成为，其出射光的光度分布(Bh、Bv)在灯具正面方向上光度(I)最高。并且，通过将来自直射光控制部的出射光的光度分布(Ah、Av)和来自反射光控制部的出射光的光度分布(Bh、Bv)合成，从而作为整体而得到比较平坦的光度分布(Ah+Bh、Av+Bv)。
摘要（英）：

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.
