Abstract: A battery operated LED lighting apparatus including: a battery outputting a battery voltage; a light emitting diode or array of light emitting diodes; and a power supply including a boost regulating circuit. The power supply being in communication with the battery and the light emitting diodes such that a constant voltage or constant current is supplied to the light emitting diodes as the battery discharges and the battery voltage falls below the output voltage. In a preferred embodiment the power supply further includes a buck regulator to maintain the proper output voltage when the battery voltage is greater than the output voltage.

Abstract: A lighting apparatus for film, television, video capture, motion picture and photography which includes a Fresnel (725) lens fixed in a housing (710) which contains a tight array of high power LEDs. The LED panel (750) or board is mated to a heat dissipating apparatus to provide active cooling and together forming an LED engine (100). The LED engine is mounted to a slider (780) allowing the LED engine to be adjusted within the housing with respect to the lens. Light shaping diffusion may be included on the housing. A power supply unit may also be included in the housing. When in electrical communication, the LED engine and power supply unit function as an integrated self-contained lighting apparatus. Optionally, the power supply may have an integrated dimmer switch, and may be capable of receiving PFC power or have an integrated battery unit.
