Abstract

An illumination light source is disposed in a housing of a tool without a fastener or snap. The lighting source includes a plurality of lighting elements, such as LEDs, disposed on a circuit board. During use of the tool, the lens and the housing cooperatively direct light emitted by the lighting element away from the user's eye.

Description

technical field [0001] The present invention generally relates to illumination sources for hand tools. Background technique [0002] Hand tools, such as, for example, motorized ratchet wrenches and drivers, for example, are commonly used in automotive, industrial and household applications for tightening and loosening workpieces, such as threaded fasteners, and for applying torque and / or angular displacement to workpieces. These hand tools are often used in areas that are dark and have limited space, such as an engine room, making it difficult to see or perform certain jobs. [0003] Typically, hand tools include a single LED positioned adjacent to a drive lug of the tool. However, this single LED only illuminates a small area adjacent to the drive lug and thus does not provide sufficient illumination to dimly lit areas around the workpiece. Other tools that include multiple LEDs surrounding the tool's housing require additional structure and / or fasteners attached to the t...
