An electrical component, such as a light, a floodlight, a lighting unit and battery charger assembly. The light may include a light body including an illuminating portion, a housing operable to support the light body, the housing being operable to support a removable power tool battery pack, and an operational circuit supported by the housing, the operational circuit being electrically connectable between the illuminating portion and the battery pack such that power is suppliable to the illuminating portion, the circuit including a battery charging circuit portion electrically connectable between the battery pack and a power source such that power is suppliable from the power source to the battery pack to charge the battery pack. The operational circuit may be electrically connectable between the illuminating portion and the power source such that power is suppliable to the illuminating portion from the power source.

The present invention relates to electrical components, such as lighting units, and, more particularly, to a lighting unit, a battery charger, etc.
Lighting units, such as, for example, floodlights, are used on many job sites. A floodlight generally provides a wide area of illumination for the job site. A floodlight is typically supported on a surface during use (though it may be carried by a user at times). In contrast, a flashlight generally provides a comparably small area of illumination and is typically carried by a user during use (though it may be supported on a surface at times).
Many cordless products (e.g., cordless power tools, equipment, etc.) are also used on the job site. A battery charger (e.g., a power tool battery charger) and a lighting unit, such as, for example, a floodlight, as a single unit provides multiple functions in a single product.
FIG. 1 is a perspective view of a lighting unit, illustrating a light portion in an open condition.
FIG. 2 is a perspective view of the lighting unit shown in FIG. 1, illustrating the light portion in a closed condition.
FIG. 3 is a side view of the lighting unit shown in FIG. 1, illustrating the light portion in the closed condition.
Before at least one embodiment of the invention is explained in detail, it is to be understood that the invention is not limited it its application to the details of the construction and the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practices or carried out in various ways. In addition, it is understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
The use of “including”, “comprising”, or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms “connected”, “coupled” and variations thereof herein are used broadly to encompass direct and indirect connections and couplings. In addition, the terms “connected” and “coupled” and variations thereof are not restricted to physical or mechanical connections or couplings.
FIGS. 1-3 illustrate a lighting unit 10 embodying one or more independent aspects of the invention. In some independent aspects and in some constructions, the lighting unit 10 is a floodlight. In some independent aspects and in some constructions, the lighting unit 10 includes a battery charging circuit for charging a battery such as, for example, a power tool battery pack B. In some constructions and in some independent aspects, the lighting unit 10 is selectively powered by an AC power source (e.g., line power) or by a DC power source (e.g., the battery pack B).
