20080266870 | METHOD AND APPARATUS TO IMPROVE EFFICIENCY OF LIGHTING - 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. | 10-30-2008 |
20080273335 | FULL OR NEAR-FULL CUT-OFF VISOR FOR LIGHT FIXTURE - A wide area lighting fixture includes a relatively large visor extending from a bowl shaped fixture reflector. The distal portion of the visor extends relatively far outwardly and downwardly and around the fixture opening. In operating position, the visor blocks most or all off field direct view of the light source in the fixture. Optionally a light absorbing surface or insert can be placed at the very bottom of the bowl shaped reflector to absorb or otherwise stop light that otherwise might go off-field to further control spill light, glare, and sky glow or uplight. | 11-06-2008 |
20090002993 | GEARED TILT MECHANISM FOR ENSURING HORIZONTAL OPERATION OF ARC LAMP - 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. | 01-01-2009 |
20090051299 | LINEAR REACTOR BALLAST FOR SPORTS LIGHTING FIXTURES - A means and method for increasing use of a light from a high intensity lighting fixture to a target area without an increase in energy use. One aspect increases the electrical efficiency of transmission of electrical power from an electrical power source to the lamp such that for the same cost of electrical energy, more electrical energy is available for production of light. Conversely less electrical energy could be purchased to produce the same amount of light. In another aspect electrical components along the electrical service path can be utilized with increased electrical efficiency towards the same end. | 02-26-2009 |
20090122550 | GEARED TILT MECHANISM FOR ENSURING HORIZONTAL OPERATION OF ARC LAMP - 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. | 05-14-2009 |
20090129081 | ELECTIVE LIGHTING FIXTURE VISORS TO REDUCE OFF-TARGET GLARE AND SPILL LIGHT - 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. | 05-21-2009 |
20090135411 | METHOD, APPARATUS, AND SYSTEM OF AIMING FIXTURES OR DEVICES - An apparatus, method, and system of aiming devices such as antennas, free-space optical communication transmitters and lighting fixtures. One aspect of the invention mounts a substantially collimated light source on a device or lighting fixture. The direction of the substantially collimated light source is fixed in a known relationship to the aiming direction of the fixture or device. By finding the substantially collimated light source either by direct viewing, in a mirror, or with a light sensor, the aiming direction of the fixture or device can be derived by using the known the relationship between the substantially collimated light source and the aiming direction of the fixture or device. Thus, the aiming direction of the fixture or device can be derived without operating the fixture or device and can be derived even at relatively remote locations from the fixture or device. The apparatus and method can be used on one fixture or a plurality of fixtures or devices. It can also be used on one fixture of an array of fixtures or devices to aim the entire array. | 05-28-2009 |
20090135596 | METHOD, APPARATUS, AND SYSTEM OF AIMING LIGHTING FIXTURES - 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. By finding the substantially collimated light source either by direct viewing or in a mirror, the aiming direction of the lighting fixture can be derived by using the known the relationship between the substantially collimated light source and the aiming direction of the fixture. Thus, the aiming direction of the fixture can be derived without operating the lighting fixture and can be derived even at relatively remote locations from 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. | 05-28-2009 |
20090161363 | APPARATUS AND METHOD FOR ELIMINATING OUTGASSING OF SPORTS LIGHTING FIXTURES - 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. | 06-25-2009 |
20090188207 | POLE COVER OR SLEEVE - 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. | 07-30-2009 |
20100277924 | METHOD AND APPARATUS TO IMPROVE EFFICIENCY OF LIGHTING - 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.

20110013401 | SPORTS LIGHTING FIXTURE HAVING DIE-CAST FRAME IN HIGH-REFLECTANCE MATERIAL - 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. | 01-20-2011 |
