Abstract
An umbrella has a first support member, a plurality of ribs supported by the first support member, and a canopy supported by the plurality of ribs. At least one of the plurality of ribs has, in cross section, a bottom wall, first and second upstanding side walls extending upward from the bottom wall, and a web extending between the first and second side walls at a location intermediate the bottom wall and the upper side wall ends. The web and upper portions of the first and second side walls form a channel. A first hole extends through the web, and a second hole extends through the bottom wall generally in coaxial alignment with the first hole. In a disclosed embodiment, a light bulb is disposed within either or both of the first and second holes, and an insulated electrical conductor runs along the length of the rib within the channel to connect the light bulb to a source of electrical power.
