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.
摘要:
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.
摘要:
A highly controllable way to light target areas includes a primary reflector which generates a defined primary beam in association with a light source. The primary beam, or at least a portion of the primary beam, is directed onto a secondary reflector which generates a secondary beam to the target space. Other options, enhancements, alternatives, and features are possibly utilized in the principles of the present invention whereby a primary light source is reflected off of a secondary reflector means. The secondary reflector can be configured in any number of contours, shapes, specularities, or other characteristics to alter and control the characteristics of the secondary beam.

A highly controllable way to light target areas includes a primary reflector which generates a defined primary beam in association with a light source. The primary beam, or at least a portion of the primary beam, is directed onto a target reflector which generates a secondary beam to the target space. The secondary reflector can be configured in any number of contours, shapes, secularities, or other characteristics to alter and control the characteristics of the secondary beam. Other options, enhancements, alternatives, and features are possibly utilized with the principles of the present invention or by a primary light source is reflected off a secondary reflector means. This invention supplies a way to light the underside of an airplane while, for example, a wing is being painted. A light source is place a substantial distance away from the wing of the airplane to be painted. The light source includes a primary reflector to direct the light. A secondary reflector is placed at such a location that light emitting from the light source would be reflected to the underside of the airplane wing.
