Abstract
A work light including an elongated housing having a handle portion carrying work light controls, and a light-emitting portion including a plurality of electrically interconnected light-emitting diodes (LEDs) mounted on a substrate mechanically and thermally coupled with a heat sink, wherein the plurality of LEDs include at least two independently controllable groups of LEDs. The work light further includes a power cord electrically extending therethrough for connecting multiple lights in series.
Claims19
A work light, comprising:
- (a) an elongated housing, comprising:
- (i) a handle portion carrying work light controls;
- and
- (ii) a light-emitting portion including a plurality of electrically interconnected light-emitting diodes (LEDs) mounted on a substrate mechanically and thermally coupled with a heat sink, wherein the plurality of LEDs include at least two independently controllable groups of colored LEDs;
- and
- (b) a power cord electrically extending through the housing terminating at opposed ends in electrical connectors for connecting multiple work lights in series.
3 more elements
A work light, comprising:
- (a) a housing defining a handle for gripping and manipulating the work light;
- (b) a light-emitting portion including at least one light-emitting diode (LED) mounted on a substrate mechanically and thermally coupled with a heat sink operable for dissipating heat generated during the operation of the at least one LED, the heat sink including a body portion in full-face contact with the substrate and a plurality of fins extending outwardly away from the body and the at least one LED and defining air gaps therebetween;
- (c) a light control system carried by the handle operable for powering on/off the at least one LED;
- (d) a cover lens for protecting the at least one LED from damage;
- and
- (e) a power cord adapted for being connected to a power source to supply electrical power to the work light.

- (b) a power cord electrically extending through the housing terminating at opposed ends in electrical connectors for connecting multiple work lights in series;
- (c) a heat sink including a planar attachment surface that corresponds to a planar surface of the substrate, the heat sink further including a plurality of heat-dissipating spaced-apart fins that project outwardly from the body away from the plurality of LEDs, wherein distal ends of the fins collectively define a substantially semi-circular shape in vertical cross-section;
- and
- (d) an optically transparent cover lens enclosing the light-emitting portion of the elongated housing.
