OPERATING LAMP PROVIDED WITH A LIGHT PIPE

摘要

A lamp arrangement for medical operating rooms. Light from a point source is focused by a spheroidal reflector on the inlet end of a light pipe, which transmits it to a reflector arrangement below. In one embodiment a straight light pipe is employed with a stepped prismatic element to direct the light upward onto a stepped reflector. In an alternate embodiment a curved light pipe is employed to transmit the light directly onto a parabolic reflector. The light rays leaving the final reflector in both embodiments are parallel and of uniform intensity.
