Abstract: An apparatus and method for high intensity lighting includes, in one aspect, a reflector frame having a main portion generally following a surface of revolution of the type that produces a converging beam and a second portion following a surface of revolution of the type that produces a different shape beam. Placement of the second portion in the reflector frame allows shifting of parts of the light beam in desired directions.

Abstract: A capacitor assembly comprises a capacitor housing wherein a relatively larger main capacitor and at least one relatively smaller secondary capacitor can be enclosed and include an efficient and simple combination of electrical connections from the multiple capacitors to an external electrical connection interface. Another aspect includes a capacitor housing wherein volumetric efficiency is enhanced by the arrangement of the multi-capacitors within a given volume of a cavity of the housing. For a given size main capacitor and one or more secondary capacitors, the total volume of space occupied by those capacitors and the housing is minimized to take up minimum room in an electrical box.

Abstract: A method, apparatus, and system for increasing usable light from a high intensity lighting fixture to a target area without an increase in energy use. In one aspect, the circuit is retrofitted into an existing lamp circuit that allows selective change in operating power or wattage to the lamp, over a substantial period of operation time, to save energy. In one aspect operating wattage of the lamp would be reduced. In another aspect of the invention, reduction in operating wattage is accomplished by a switchable capacitance in electrical communication with the lamp circuit.

Abstract: A method and apparatus to increase efficiency of wide area lighting fixtures having a lamp mounting opening in a reflector or reflector frame, which results in gap(s) or spaces that do not control incident light to the intended target. The gap(s) or spaces(s) are covered with reflecting surfaces which do control incident light to increase efficiency of the fixture.

Abstract: A method and system of classifying predicted performance of HID lamps or light sources. A characteristic of each lamp or light source is measured after a relatively short time of operation of the lamp or light source. The measurement is placed into one of a plurality of classifications based on its relative value to other similar measurements. Each class is correlated to long term predicted performance of the lamp or light source.

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: 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, somewhat simulating a bowl shape, includes an inner surface with mounting structure. A high reflectance sheet or plurality of high reflectance inserts are placed onto the mounting structure to create a reflecting surface. This allows high customability of the reflecting surface and minimizes light loss.

Abstract: An apparatus and method for keeping a high intensity discharge arc tube relatively horizontal in a light fixture regardless of aiming orientation of the light fixture towards a target. In one aspect, the light source is mounted in an independently pivotal yoke in the light fixture. A gearing arrangement automatically proportionally pivots the light source relative to any pivoting motion of the fixture over a range of motion such that a selected light source orientation can be approximately maintained regardless of aiming orientation of the fixture.

Abstract: An apparatus, system, and method for increasing life of a high intensity lighting fixture light source. In one aspect, the method involves installing a new HID lamp in the fixture in combination with retrofitting a circuit that operates the lamp at a reduced wattage over a substantial period of operation time to save energy. In another aspect, the circuit comprises switchable capacitants adopted to operate the lamp at a reduced wattage over a substantial period of operation time. In another aspect of the invention, instead of retrofitting, the entire lighting fixture could be replaced at the end of a predetermined operating period and replaced with a balasting system that includes switchable levels of capacitants to reduce operating wattage to the lamp for at least the first substantial operating period.

Abstract: A method, apparatus, and system for compensating for lamp lumen depreciation. The method includes operating the lamp under rated wattage for a period towards the first part of operating life of the lamp. Operating wattage is increased at one or more later times. Energy savings are realized. The increases also restore at least some light lost by lamp lumen depreciation. The apparatus uses a timer to track operating time of the lamp. A few wattage changes made at spaced apart times can be made in a number of ways, including changing capacitance to the lamp, or using different taps on the lamp ballast.

Abstract: An apparatus, method and system for covering and protecting substantially tall poles. The apparatus includes a covering layer positionable over at least a portion of the exterior of a pole. The covering layer is non-corrosive and preferably impact and tear resistant. In one aspect of the invention, the covering layer is a sheet of material dimensioned to wrap around a corresponding part of the pole. A bracket can be used to secure the opposite adjacent edges of the wrap. Hardware can be used to secure the wrap from longitudinal movement along the pole. The wrap can be colored, textured, or patterned.

Abstract: A method for compensating for warpage or other variations in a cross arm on a pole adopted for the mounting of lighting fixtures at predetermined aiming angles relative to a target space on an adjustable mounting structure comprises designing an angular orientation of the fixture relative to a cross arm based on pre-determined assumptions of the geometry of the cross arm; after installation of the lighting fixture on the cross arm, checking for any variation from the assumed geometry; compensating for any variation in actual geometry when finally aiming the fixture to its target location.

Abstract: An apparatus, method, and system of aiming lighting fixtures. One aspect of the invention mounts a substantially collimated light source on a lighting fixture. The direction of the substantially collimated light source is fixed in a known relationship to the aiming direction of the lighting fixture.

The apparatus and method can be used on one fixture or a plurality of fixtures. It can also be used on one fixture of an array of fixtures to aim the entire array.

Abstract: A method, apparatus and system for illuminating a large area with plural high power lighting fixtures. The method includes identifying fixtures having a likelihood of affecting playability or glare or spill light relative to a point of view on or off the large area. The method includes steps to identify such fixtures for the purpose of adding a component which improves lighting or decreases glare or spill light for the point of view. A further method does so for multiple points of view relative to the large area, whether on or off the large area. One component is a long visor that would be added only to identify fixtures.
