Abstract: A lawn or patio umbrella with an integral lighting system that utilizes cold cathode ray tubes, light emitting diodes (LED's), or florescent lights, to provide relatively bright outdoor light for reading and other activities that require relatively high light intensities is provided. In one embodiment, a modular, electrically powered lawn or patio umbrella in which lighting systems, such as those utilizing cold cathode tubes, LED's, or florescent lights; cooling systems, such as those utilizing electric fans or misting systems; and motorized retraction systems; can be selectively interchanged is provided.

Abstract: An oil burning lamp has a fuel reservoir, a fuel expansion chamber releasably and sealingly coupled to the fuel reservoir, a burner assembly coupled to the fuel expansion chamber, and an adjustable wick. If the fuel in the fuel reservoir undergoes thermal expansion, it flows into the fuel expansion chamber, thereby preventing fuel leaks and spills. In the preferred embodiment, the burner assembly is permanently coupled to the fuel expansion chamber, thereby preventing users from refueling the lamp while the lamp is burning. The fuel expansion chamber also serves as an overflow fuel chamber, so that if the lamp is inadvertently knocked over, the fuel will flow into the fuel expansion chamber, not out of the lamp.
