Abstract: An apparatus, method, and system for increasing usable light to a target area. One aspect of the invention includes a lighting fixture with a visor. The visor includes an opening through which a controlled amount of light is allowed generally upwardly. A controlled amount of light within provides some uplighting above the target area or above the fixtures. In another aspect of the invention, a lighting system with a plurality of lighting fixtures would have at least some of the fixtures fitted with the visors with the openings to create a cumulative uplighting effect.
Abstract: A method, apparatus and system for illuminating a sports field. 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 field. The method includes steps to identify such fixtures for the purpose of adding a component which improves playability or decreases glare or spill light for the point of view. A further method does so for multiple points of view relative to the field, whether on or off the field. One component is a long visor that would be added only to identified fixtures.
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: 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.
Abstract: An apparatus, method, and system for lighting target areas with bollard or pagoda style or type lights in a controlled and efficient manner. The apparatus includes a housing with a light source, optic system, and a control circuit. The light source and optic system are configured to produce a highly controlled output beam pattern and shield from normal viewing angles direct sight of the source. This enables control of glare and spill light which can improve effectiveness, efficiency, and energy usage.
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: One aspect of the present invention is a non-electronic method of controlling the power provided to the lamp through use of multiple secondary taps off the secondary side of the HID ballast. This allows for a base capacitor to be used, along with the multiple secondary taps of the ballast, to vary the power to the lamp for purposes of providing constant light output, dimming capabilities, or to hold the power constant, or any combination of such.
Abstract: A luminaire assembly (10) using a double-ended, unshielded high intensity discharge (HID) light source (100). In one aspect, the assembly (10) includes a light source mount (22) adapted to manually, without tools, mount and remove the HID light source (100). The light source mount (22) can optionally include structure (106L and R, 134L and R) to automatically position the light source (100) in a desired orientation. In another aspect, the assembly (10) includes a connection (104L and R, 304L and R, 306L and R) adapted to manually, without tools, connect the light source (100) to electrical power, the connection (104L and R, 304L and R, 306L and R) can be configured to have no electrically conducting surfaces directly exposed or accessible to human fingers and can be configured to be positioned relatively away from the light source (100).
Abstract: A system for electronic scoring and score reporting of a sporting event wherein an electronic scorebook is connected to an electronic scoreboard and electronic storage of the scoring information is provided. In one embodiment, a network is used, sending or receiving information to or from the scorebook, the scoreboard or the electronic storage. In other embodiments, the Internet is used as a conduit to communicate to and from the location of sports field lighting, to control operation of the lighting, or monitor the lighting or other events at the location. The network can also be used for last mile connectivity of end users to the Internet, and to compile information from sporting events at the locations and allow access to information about the game via the Internet.
