1. A light emitting diode (LED) work light comprising:
- an outer casing including a head section and a handle section,the head section comprising a single piece metal elongate channel having a rear portion and opposing side flanges perpendicular to the rear portion, the rear portion and side flanges extending longitudinally along the channel, the channel defining an open transverse side between the opposing side flanges,a plurality of LEDs directly mounted on a surface of the rear portion inside the channel such that the channel is a heatsink for the LEDs, the LEDs generally disposed in a linear fashion along the channel, the LEDs being directional LEDs aimed to emit from the substantially open transverse side, anda transparent unitary multiple element convex lens covering the LEDs, the single piece multiple lens comprising a plurality of convex lenses including a corresponding convex lens forward of each LED, the single piece multiple lens directly affixed to the rear portion of the channel by at least one fastener that passes through the transparent unitary multiple element convex lens to the rear portion of the channel,wherein each convex lens further comprises a concavoconvex lens wherein a central part of a rear surface of the concavoconvex lens is flat,wherein forward edges of the side flanges of the channel extend farther forward from the rear surface than the unitary multiple element convex lens.

Abstract
A work light has a head section with a single piece metal channel having a rear portion and opposing side flanges. The rear portion and side flanges extending longitudinally along the channel. Light has a handle section. LEDs are mounted on channel such that the channel is heatsink for the LEDs. A transparent single piece lens assembly covers the LEDs, the lens assembly has a corresponding plurality of convex lenses, each convex lens forward of each LED, the lens assembly attached to the rear portion of the channel. Forward edges of the side flanges of the channel extend farther forward from the rear surface than the lens assembly for protection.
