Abstract
A work light including a body and a light head pivotally coupled to the body about a pivot axis. The body includes a user interface and a battery receptacle, the battery receptacle configured to receive a battery. The light head includes a housing, a light panel positioned within the housing and configured to be operated by the user interface, and a plurality of light emitting diodes (LEDs) supported on the light panel. The light head does not include a heat sink and has at least 1.5 LEDs per square inch.
Claims20
A work light comprising:
- a body including a user interface and a battery receptacle, the battery receptacle configured to receive a battery;
- and
- a light head pivotally coupled to the body about a pivot axis, the light head including
- a housing,
- a light panel positioned within the housing and configured to be operated by the user interface, and
- a plurality of light emitting diodes (LEDs) supported on the light panel, each LED having a maximum LED brightness,
- wherein the light panel produces a maximum rated brightness of the work light, wherein the plurality of LEDs are configured to cooperate to provide the maximum rated brightness of the work light, and wherein the maximum rated brightness of the work light is less than a sum of the maximum LED brightnesses of the plurality of LEDs;
- wherein the light head does not include a heat sink and has at least 1.5 LEDs per square inch.
