摘要:
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.

An apparatus and method for allowing rotational adjustment of a thread-in HID light source to a lighting fixture when in operative position in the fixture. In one aspect of the invention, a conventional thread-in arc lamp is threadably insertable into a socket that is mounted in the light fixture. A mounting interface is adapted to allow some rotation of the socket over a range.

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). In another aspect, the assembly (10) can include an ignitor circuit for the light source (100) farther away from a ballast circuit for the light source (100) but closer to the light source (100). The ignitor circuit can be in a housing (16) that is mountable to the assembly (10).
摘要:
An apparatus and method for checking alignment of a lighting fixture comprising a lighting fixture with a housing, reflective surface in the housing, light source in the housing, and a glass lens over an opening into the housing. A marking or indicia is placed on the glass lens in a known orientation with structure inside the housing that is visible from outside of the housing. By line of sight viewing of the marking or indicia, even from a distance away, an alignment of the marking or indicia with the structure inside the housing, the alignment or aiming orientation of the fixture can be determined. This can be used to check alignment of individual fixture, or can be used to check alignment of an array of fixtures, if the array has a known reference correlation to the fixture with the marking or indicia.

An apparatus, method, and system for lighting includes one or more moveable bases, one or more lighting arrays, and one or more extendable poles. The base, pole, and array are designed to allow elevation of the array to heights exceeding 35′, yet the combination is transportable by conventional over-the-road trucks. In one form, a plurality of bases, poles, and arrays are designed to fit on a conventional over-the-road trailer for transport on one trailer to a lighting location.

An apparatus and method for connecting and disconnecting electrical power to an arc tube includes a high intensity discharge arc tube having a body and electrodes extending from the exterior of the body into the interior of the arc tube body. Electrical leads are connected to the exterior ends of the electrodes and have an length that allows distal ends of the leads to be extended a distance away from the arc tube. Connectors at the distal ends of the leads are adapted to connect to electrical power leads. The connectors, the leads, and the connection of the leads to the electrodes of the arc tube all are electrically insulated from human touch. Therefore, electrical power through the arc tube can be connected and disconnected at a location away from the arc tube, without direct exposure of humans to electrically conducting surfaces for safety purposes.
摘要:
An apparatus and method for quick and easy attachment of ballast boxes to a pole by easy mounting brackets, and which also communication with the interior of the pole to allow easy electrical connection of its components. A mounting bracket allows connection of the ballast box to the pole but also allows the box to be adjusted in multiple directions relative to the pole to align openings in the box and pole. The entire assembly can be shipped on sight and quickly and easily assembled without intensive labor, equipment, or cost.

A mobile lighting system includes a self-powered mobile base that can be driven long distances and maneuvered in tight locations. An articulateable boom is mounted on the base and has multiple degrees of freedom of movement. A light array is attached to the end of the boom and has additional degrees of freedom of movement. One or more fixtures are mounted on the end of the boom and also have several degrees of freedom of movement, as well as having structure to vary the beam pattern output from each fixture. The system contains power generating means as well as all structure to operate the lights and the boom. Additional features which facilitate the efficient and advantageous provision of the mobile lighting system are also disclosed.
