Abstract: An arc discharge headlamp system employs a single continuously operating arc discharge source to provide both high and low beam patterns. The continuously operating arc discharge increases lamp life and eliminates the problem in arc light source headlamp systems of momentary dimming when switching to high beam operation due to mercury condensing within source. The headlamp has an arc light source mounted horizontally within a reflector. Light from an arc light source is reflected by the reflector through a lens to form a low beam pattern. A mirror within the reflector is positioned to form a virtual image of the light source and which is directed towards a second lens concentric with the first lens to form a high beam pattern when combined with the low beam pattern. Switching between the high beam and low beam patterns is accomplished in a variety of ways.

Abstract: A channel and locking end tip for vinyl tube strip lighting. The tip includes a locking nib which is positioned within a channel opening for preventing the tip from shifting relative to the channel. To remove the tip, its outer end is pivoted upwardly such that the locking nib is spaced slightly above the channel bottom wall. A screw hole is provided through the tip body and channel for mounting. The vinyl tube light overlies the flange when carried by the channel. The mounting screw is external of the lighting bed such that the strip light may be fully assembled by the manufacturer and installed by the user with minimum effort.

Abstract: The flat panel illumination system includes a high intensity light source with a contoured reflector assembly for providing light to the input of an optical mixer and heat removal device. The optical mixer and heat removal device removes infrared radiation and transmits de-focused light to the input ends of a plurality of rectangular couplers connected to light conducting cables which are in turn connected to the light emitting optical fibers for a light emitting panel. These fibers are woven in accordance with specific weave ratio ranges and weave configurations to emit light uniformly across the extent of a light emitting fabric surface.

Abstract: An arrangement and method for providing an elongated light source, such as for illuminating a sign or the like or, for other display, which includes emitting light from an exterior light source into an inner tube having a portion lined with a high reflectance film of prismatic lenses, the tube having a light-transition opening along its length, with a diffusing medium substantially diametrically opposite such opening, and optionally a reflector at one end of the inner tube. The inner tube is concentrically surrounded by an outer tube having light-transmissive portions of different colors. The outer tube is rotatable relative to the inner tube. The emitted light propagates in the inner tube by reflecting from the high reflectance lining and the reflector to impinge on the diffusing medium and thereby transmit light outwardly through the light-transmissive opening and thereafter through a selected one of the colored portions so as to project colored light against a sign or like object.

Abstract: An illuminating device comprises a tubular outer sleeve (12) provided with an elongated transparent window (13), with an inner sleeve (22) formed with an aperture (27). The inner sleeve (22) houses a pair of self-luminous light sources (30).

The standard fixture includes a halogen bulb with its own reflector. The emergency lighting fixture includes a halogen bulb/reflector unit with the emergency self focusing bulbs concentrically spaced around it. Both light sources pass focused light directly into the space below the ceiling for meeting test point candle power requirements.
