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: 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: An apparatus and method for adjusting a high intensity discharge arc tube to a predetermined (e.g., relatively horizontal) operating position 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 mechanical linkage proportionally pivots the light source relative to any pivoting motion of the fixture over a range of positions such that a selected light source orientation can be approximately maintained regardless of aiming orientation of the fixture.

Abstract: An apparatus and method for reducing lumen depreciation caused by other than lamp lumen depreciation. In one aspect, manufacturing and assembly of the fixture uses clean-room light techniques. In another aspect of the invention, materials that have a propensity to outgas are shielded from direct exposure to light energy. Other aspects of the invention include other methodologies to eliminate causes for lumen depreciation.

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: 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. In one aspect the invention pertains to solid state sources. The invention can pertain to a variety of applications including wide area lighting, indoor lighting, pathway lighting, parking lot lighting, street lighting, under-counter or -cabinet lighting, and others.

Abstract: A water soluble, water stable, titanium alkoxide composition represented by the chemical formula (OC6H6N)2Ti(OC6H2(CH2N(CH3)2)3-2,4,6)2 with a theoretical molecular weight of 792.8 and an elemental composition of 63.6% C, 8.1% H, 14.1% N, 8.1% O and 6.0% Ti.

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.
