摘要:
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.

摘要:
A method and apparatus for controlling power to relatively high power devices by adding or subtracting capacitance. A plurality of capacitors are connected in parallel. The plurality of capacitors are in series with the device. Operating power to the device can be adjusted by adding or subtracting capacitors in the device circuit. The high powered contactors are controlled by a small power control input from an electronic timer. In one embodiment the electronic timer comprises a digital timer/controller which is programmable to automatically actuate designated contactors at different pre-programmed times sensed to by the timer/controller based on accumulated operating time of the high powered device. The combination allows an easily adjustable yet small sized and relatively inexpensive set of components for adjusting high powered devices.
摘要:
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.
摘要:
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.
摘要:
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.

A means and method for rigidly elevating a structure includes a base member securable in the ground and which has a portion extending above the ground. A pole section, having a bore inside a lower end, and an upper end, can be stacked upon the base means upwardly by slip fitting the pole section onto the base end and securing it in place. A flexible, easily transportable and durable system is thereby created for elevating structures.
