Abstract
A portable work light has a handle to which a head is pivotally attached. The head houses a light source and a reflector that projects a beam of light. The head has an air inlet and outlet with a fan that forces air from the inlet to outlet thereby cooling components inside the head. The work light may be powered by either a battery which is releaseably connected to the handle or from an external source via an electrical cord that connects to a socket in the handle. An optical fiber assembly may be releaseably attached to the head over the opening to direct light from source through a fiber optic cable to illuminate small recessed working areas.
Claims14
A portable work light comprising:
- a handle having electrical terminals for connection to a battery;
- a head pivotally attached to the handle and having a opening, a first air inlet and a first air outlet, said head having a light source with a reflector to direct light from the light source through the opening;
- a fan mounted within said head for drawing air through the inlet, forcing the air over a surface of the reflector and through the outlet;
- a battery releaseably connected to the handle and engaging the electrical terminals for receiving electricity to power the fan and the light source;
- and
- an optical fiber adapter having a coupling for releaseably attaching to said head over the opening to receive light from the light source, and a fiber optic cable with a first end connected to the coupling for receiving light and a second end from which received light is emitted.
The portable work light as recited in claim 4 wherein the electrical cord has a third electrical connector for coupling to an electrical circuit of a motor vehicle.
A portable work light comprising:
- a handle having electrical terminals for connection to a battery, and having an electrical connector;
- a head pivotally attached to the handle and having a opening, a first air inlet and a first air outlet, said head having a light source with a reflector to direct light from the light source through the opening;
- a fan mounted within said head for drawing air through the inlet, forcing the air over a surface of the reflector and through the outlet;
- a switch assembly operably connected to control a flow of electric current from the electrical terminals and the electrical connector to the fan and the light source;
- a battery releaseably connected to the handle and engaging the electrical terminals for receiving electricity to power the fan and the light source;
- an electrical cord having a second electrical connector which mates with the first electrical connector;
- and
- an optical coupling releaseably attached to said head over the opening to receive light from the light source, said optical coupling having an outer wall with a conical shape, and an inner wall with a conical shape and concentrically within the outer wall thereby defining an air passage therebetween, the air passage having a second air inlet which communicates with the first outlet of the head and having a second air outlet from which air moved by the fan flows;
- a fiber optic cable with a first end connected to the coupling to receive light from the light source and having a second end from which received light is emitted.
