On-camera LED fresnel lighting system including active cooling
Abstract:
A lighting apparatus for film, television, video capture, motion picture and photography which includes a Fresnel lens fixed in a housing which contains a tight array of high power LEDs. The LED panel or board is mated to a heat dissipating apparatus to provide active cooling and together forming an LED engine. The LED engine is mounted to a slider 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.
