ABSTRACT:
An improved dust collection and illumination system is utilized in association with a plurality of work areas at which dust particles are formed during work operations. A combination lamp and dust collector is mounted on a workbench at each of the work areas and is connected with an exhaust manifold which conducts a flow of air and dust particles from the work areas to the intake of a blower. Each combination lamp and dust collector includes a reflector which is connected with the manifold by a flexible conduit and a light bulb which is mounted in the reflector and is effective to illuminate a work surface. Air and dust particles are drawn into the reflector, around the light bulb to cool the bulb, and through the flexible conduit and manifold to the blower. A linkage is utilized to support the reflector above the work surface. This linkage is adjustable to enable the position of the reflector to be changed.
