Abstract

PURPOSE: To obtain a uniformly light and reliable equipment by forming reflectors which are provided with lighting windows in the internal circumferential part on the surface of a transparent or semitransparent circular photoconductive substance having holes to which a light sources are fitted.
CONSTITUTION: A transparent or semitransparent photoconductive substance 10 has plural holes 10a available for light sources which are bored from the outer circumference to the center in order to hold the light sources. On the surface of the circular photoconductive 10 are formed reflectors 12, 13 which are separated into two pieces excepting a lighting window 10b in the inner circumference part. The reflectors 12, 13 can be used as a feeding ring to the light sources 11 if they are coated by a conductive film. Light sources 11 like miniature lamps or LEDs, etc. are inserted into light source holes 11a, lead wires 11a, 11a are binded to the reflectors 12, 13 with conductive binder, etc. and the opening parts of the light source holes 10 are covered with light protective filler 15 to prevent light from leaking.
