COMPACT LED WORK LIGHT

Abstract

A work light having a work light body including handle section and light head section, an elongate housing, a battery compartment and a component chamber longitudinally aligned within the housing, a battery, an LED circuit board assembly extending longitudinally within the housing and having a substrate layer, an external component layer on a first side of the substrate layer, and a driving component layer on an opposing second side of the substrate layer. Overlapping portion of the LED circuit board assembly in close proximity to the battery. Also, at least one LED on the external component layer, the external component layer facing transaxially outwardly from the housing such that light emitting from the LED emits from the light head section. At least one driving component on the driving component layer, all driving components placed on an extending portion of the LED circuit board assembly over the component chamber.
