Illumination system utilizing H.I.D. (high intensity discharge) lamps, and having a subordinate lamp automatically activated to establish immediate illumination when the H.I.D. lamp circuit is turned on, i.e., without awaiting the usual warm-up period, and to maintain illumination during periods of voltage dip (which normally extinguishes H.I.D. lamps) in the circuit supplying them, as well as during subsequent recovery and restarting the H.I.D. lamps after extinguishment as a result of voltage ...

An illumination system, particularly adapted to use in hospitals, has an elongated, low-profile fluorescent lighting fixture on the side of and parallel to a track, a reading-examination light mounted on one end of a telescoping boom, the other end of which is swingably connected to a boom mount rotatably carried by a carriage mounted to roll along the track. The lighting fixture includes means for providing low brightness down lighting and higher brightness side lighting. The reading-examinatio...

This invention relates to an emergency illumination system which is attachable to a fender portion of a vehicle and operable to both light the area adjacent and about the wheel structure plus outwardly therefrom to aid in changing a flat tire and illumination during emergencies. The emergency illumination system in one embodiment includes a lighting means having a light assembly attached at each fender portion and operable through an electrical means to either (1) illuminate all the wheel well a...

An illumination device used in the case of forming, on a dupe film, a visible copy of an image pattern of a master film. The illumination device comprises a light source including a center portion having a high brightness and a peripheral portion for emitting light in all directions, and a collimator lens having an optical axis that passes through the high brightness center portion of the light source.

The illumination device comprises a body, an illumination means, a holding means and a switching means, the last mentioned three means being attached to said body. Said holding means includes a battery and a biasing means made of an electrically conductive material. The holding means is made of an electrically conductive material and is constantly electrically connected to one electrode of said battery through said biasing means. The biasing means is designed to function so as to keep the other ...

Different portions of an area are selectively highlighted in response to observer proximity. An adjustable dimmer establishes the non-highlight illumination level for each area. The dimmer is overridden by observer-sensing circuitry to produce the highlight illumination level.

The illumination apparatus includes: a wall having a plurality of recessed wall portions; a plurality of electrically illuminating mechanism; a plurality of supporting mechanism, mounted on the wall, for supporting a corresponding illuminating mechanism so as to light a corresponding recessed wall portion; and controlling mechanism, electrically connected to each illuminating mechanism, for controlling illumination of each illuminating mechanism.

Illumination apparatus provides for uniform illumination of a planar original by use of a single flash lamp. A pair of parabolic reflectors partially surround the lamp and direct two separate collimated bundles of light toward opposite sides of the original. A planar reflector positioned in the path of each collimated bundle of light intercepts and reflects the collimated light rays upon the original to uniformly illuminate the original from opposite sides.

A transparent, generally wedge-shaped linear illuminator is used to provide a uniform level of illumination suitable for performing various functions in a reproduction device. One function is to provide uniform illumunination of a charged surface so as to selectively erase charge on said surface. Another is to illuminate a document in an illumination plane. In a specific embodiment, the illuminator consists of a glass or plastic body having a first sector formed with parallel sides and a second ...
