摘要:
A luminaire has a spherical or ovoid reflector formed with asymmetrical voids that allow beams from the lightbulb in the reflector to emerge side-by-side through the voids in opposite directions after reflection from opposite internal surfaces of the reflector.

An indirect room lighting system has a diffuse reflecting upper band around the walls about 15 to 24 inches high. A luminaire illuminates this diffuse reflecting band with a beam of light having a radiation pattern broad horizontally and narrow vertically confined essentially to the region of the diffuse reflecting upper bands. The reflector of the luminaire may be positioned at a 45.degree. angle to the walls in the corner, intersecting in the corner, or in the center of the room comprising a Fresnel cylindrical lens, or it may take other forms.

A light source is disposed within a light reflector formed to direct a light beam through an open end of the reflector and light controlling means for projecting a modified light beam from the same reflector.
