ABSTRACT:
An illumination device has a light-transmitting member formed in the shape of a toroid having a light-receiving surface and a light-emitting surface, the light-transmitting member defining a central axis, a light source located along the light-transmitting member central axis, and a light-directing housing for guiding light from the light source into the light-receiving surface of the light-transmitting member. The light-transmitting member may have optical waveguide and light-scattering characteristics, whereby the light-transmitting member emits light having a substantially uniform intensity along the light-emitting surface. The light-directing housing has a top reflector member and a bottom reflector member positioned on opposing side of the light source and cooperating with the light-transmitting member such that light is emitted only through the light-transmitting member.
