Abstract (en)
[origin: WO2007128126A1] An LED work light has multichip LEDs and a diffusing dome. Each LED may have separate electrical terminals for each chip. The LED work light may have convex lenses forward of each LED. Convex lenses may be hemispherical. Convex lenses may have a nonhemispheric curved surface whose cross section has at least one circular arc and no non-circular arcs. The LED work light has a battery or receives power from an external power source. The LED work light may have a transparent plastic tube as a structural member. A replaceable plastic cover may be added to protect any structural tube or other major transparent part of the LED work light from abrasions. The plastic cover may be tubular. The plastic cover may comprise laminations of plastic that can be removed individually after being abraded. Any external power source may be a wall transformer type and may have current limiting means. The LEDs may be attached to the rear surface of an LED PCB that is fastened to a heatsink in a manner achieving thermal contact between the rear surfaces of the LEDs and the heatsink. A position sensing switch may be used.
