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.
