Abstract:
The present invention provides a high-power optical element street lamp using a thermocouple so as to sharply reduce the amount of power consumption required when the street lamp is turned on and to minimize the cost of power. The high-power optical element street lamp using a thermocouple comprises: a body part which is fixedly installed on a ground surface and is formed to be elongated upward; a lamp head part which is provided to face a downward ground surface at a position spaced forward from the upper end of the body part; and a power supply part which is fixedly installed on the body part, supplies power to the lamp head part, and applies energy required for driving so as to enable operation control, wherein the lamp head part comprises: a circuit board which is connected to the power supply part to receive power and to operate, and is made of a metal material having high thermal conductivity; one or more optical elements which are installed and located on a lower surface of the circuit board; a molding cover which is connected to the lamp head part from a lower side of the optical element, and protects and supports the optical element; and a heat-radiating plate which is installed on top of the circuit board, and is provided with a plurality of heat-radiating fins to radiate heat generated and transferred from the optical element and circuit board. Here, the heat-radiating plate includes a thermocouple, which is disposed in a grid pattern on the surface of each heat-radiating fin to convert radiated heat into a form of thermo-electromotive force and forms contact points, at which two types of metals having different thermal conductivities intersect with each other, to generate thermoelectric current.
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.

Abstract:
A lighting system (100) is presented that includes a replaceable illumination module (10) removably coupled to a base module (15). The replaceable illumination module includes one or more solid state lighting elements (14) on a printed circuit board (18) electrically and thermally connected to the base module. The base module may include a heat sink, where the heat sink is in thermal contact with the replaceable illumination module, and dissipates heat generated by the one or more solid state lighting elements during operation of the lighting system. The replaceable illumination module may also include one or more beam conditioning elements (12) for generating a specified beam. The lighting system may be connected to an automated control network and may be automatically controlled thereby, or may be used to control some other system. The heat sink may be generated via a dynamically controllable extrusion die.
