| 摘要 |
A light emitting assembly (100) has independently operable, planar light emitting modules (400a, 400b), each including an optical conductor (401a, 401b) having a planar front major surface (153), a back major surface (155) opposite the front major surface, a light input surface (422), and a pattern of well defined light extracting optical elements (411). The optical conductor tapers distally from a thicker proximal end (402a, 402b) adjacent the light input surface to a thinner distal end (404a, 404b). An LED light source (420a) located adjacent the light input surface is small relative to the length and width of the optical conductor. The light emitting modules are arranged in tandem with the thinner end of the optical conductor of one light emitting module adjacent the thinner or thicker end of the optical conductor of the next light emitting module, and have front major surfaces that are nominally coplanar. |
