AUTOMOTIVE LIGHTING LAMP CAPABLE OF CONSTITUTING THE REAR SURFACE OF A TRANSMISSION MEMBER AS OPTICAL REFLECTION CONTROL SURFACE

摘要

PURPOSE: An automotive lighting lamp is provided to easily forming a light distribution pattern by reflecting light from a light emitting device which is arranged toward a front side.;CONSTITUTION: A light emitting device(12) comprises a light emitting surface which is extended as a straight type. The bottom edge of the light emitting surface of the light emitting device is located on a horizontal line which is crossed with an optical axis. The front surface of a transmission member(14) is composed of a flat surface which is crossed with the optical axis. A rear surface of the transmission member is composed of an optical reflection control surface. A second part(Z2) is located in the neighborhood of a horizontal surface which includes the optical axis.;COPYRIGHT KIPO 2012
