Abstract:
A method of increasing useable light from a high intensity arc lamp without an increase in energy use. In one aspect, the method modifies the conventional HE) arc tube by operating it without heat reflective coatings on opposite ends. In another aspect of the invention, the salt pool inside the arc tube is increased. In a further aspect, the arc tube is operated at or near horizontal. These aspects can be used in any combination.
Abstract:
An apparatus, method, and system for high intensity lighting with target area. One aspect includes extending a structure externally of a light fixture and utilizing a very high total reflectance reflecting surface on the structure to redirect incident light toward the target area in a highly efficient manner.

Abstract:
A high intensity discharge (HID) light fixture includes a reflector frame which supports an independent high reflectivity reflecting surface. The reflector frame supports a glass lens with anti-reflective coatings on its surfaces and a visor or extension that also supports an independent high reflectivity reflecting surface. The high reflectivity reflecting surface has various sections that adjust portions of the beam created by the fixture to better place light on a target area. The reflector frame is attachable to a lamp cone. An adjustable knuckle attaches between to a cross arm on a pole and the lamp cone. An HID lamp, when mounted in the lamp cone, has its arc tube substantially surrounded by the high reflectivity reflecting surfaces of the reflector frame and visor. A lamp positioning mechanism automatically adjusts orientation of the arc lamp over a range of pivot angles for the lamp cone relative the knuckle. The HID lamp has an increased metal halide salt pool and does not include white oxide coatings at opposite ends. The lamp and the lamp positioning mechanism are configured to position the arc tube of the lamp horizontal over the normal range of aiming angles for the fixture. The modified HID lamp, its operating position, the high reflectivity reflecting surfaces, and other aspects of the fixture produce more light from the fixture than without these features for the same amount of energy to operate. Optionally, a ballast circuit can save energy over operating life of the lamp.
Abstract:
A solvent band casting system is disclosed in which a tank is to mix and/or agitate and/or store a polymer solution for a band casting machine having at least a first and a second rotating drums about which a continuous metal band is tensioned to travel with the rotation of the drums. A sheeting die applies the polymer solution from the tank to the metal band where a drying chamber enclosing a least a portion of the metal band downline of the sheeting die, is used to remove solvent from the polymer solution as it travels in a thin sheet on the metal band. The drying chamber may include at least one heater with a plenum for directing a flow of heated air counter-current to the travel of the metal bank for more effective drying. Additionally, a surfactant applicator in communication with a supply of surfactant and a portion of the metal band may be used to attain a substantially bubble-free film. A buffer configured to pivotably abut the metal band is usable on-line to lessen system downtime. Finally, a system controller is connected such that the operation of at least one of the band casting machine, the sheeting die, the drying chamber, the surfactant applicator, and the buffer is monitored and/or controlled by the system controller.
Abstract:
An apparatus and method for increasing operational life and performance of an arc tube or lamp. The method includes operating the arc tube and applying steps to encourage isothermal conditions around the arc tube. In one embodiment of the method, the arc tube (12) is rotated (40/41) during operation. Another embodiment includes directing air (32/34/26) onto the operating arc tube (12). An exemplary embodiment relates to a substantially high wattage HID unjacketed double ended arc lamp (12) operated in a substantially horizontal position, but the invention is not limited to the same.

Abstract:
A lighting fixture is presented comprising a plurality of modular apparatuses wherein each modular apparatus comprises one or more light sources and one or more light directing or light redirecting devices. Methods of adjusting one or more components of said lighting fixture about one, two, or three axes are presented whereby the lighting needs of a target area - even one of complex shape - may be addressed and in a manner that promotes compact fixture design with low effective projected area (EPA) without sacrificing transmission efficiency of the light sources.
Abstract:
An apparatus and method for a high intensity lighting fixture. In one aspect, instead of a spun aluminum bowl-shaped reflector, a die cast metal reflector frame (30) , somewhat simulating a bowl shape, includes an inner surface with mounting structure . A high reflectance sheet or plurality of high reflectance inserts (120) are placed onto the mounting structure to create a reflecting surface (32) . This allows high customability of the reflecting surface and minimizes light loss.
