REFLECTIVE AND REFRACTIVE WAVE LENS FOR LIGHT SHAPING

摘要

A lighting assembly which includes source means (162) and collimating means (164 and 166) for substantially collimating the light from the source. There are transmission means for transmitting the substantially collimated light to a point remote from the collimating means, and, in one arrangement, having an upper section which allows transmission of light therethrough and a lower section which reflects light. Light direction modifying means such as a lens or a reflector is located in the transmission means and remote from the collimating means for receving light from the collimating means and modifying the direction of the light to pass outside of the transmission means through the light-transmitting section (199). The light direction modifying means includes a large plurality of prisms on the outer surface thereof. The prisms may be arranged so that the radii of several adjacent ones substantially meet at a point, thereby to form a "wave" lens (175).
