A novel crankcase and umbrella frame for a crank operated umbrella, which illuminates an area about the umbrella, including an umbrella canopy. Crank umbrella frames generally include a support pole, a base, a plurality of pivoting umbrella ribs, and an operating assembly. The operating assembly provides a crank, a crankcase, and a transmission for opening or closing the umbrella ribs. The crankcase of the present invention houses not only a portion of the crank, but at least one integrated luminaire configured so as to be capable of providing light in a desired direction, including toward a supported umbrella canopy to produce a pleasing and diffuse light. Integrating such luminaire in a low profile, convenient, and aesthetically pleasing manner into the crankcase produces a diffuse light without interfering with the operation of the umbrella canopy or activities in the vicinity of the umbrella.
