Abstract: A new and improved illumination apparatus and method of making and using it for illuminating large and small areas, such as the exterior and interior of a motor vehicle, building structure or the like. The apparatus includes an elongated neon tube for radiating bright glowing light both radially and axially, an elongated tube holder for holding the neon tube stationary relative to a mounting surface, an energy conversion device adapted to be coupled to a source of low voltage power for electrically energizing the neon tube, and a mounting arrangement to secure the energy conversion device within the tube holder without blocking the bright glowing light radiating axially from the neon tube. The preferred method of using the apparatus is mounting the apparatus to a surface in close proximity to an area to be illuminated and coupling the apparatus to a source of low voltage direct current electrical power.
Abstract: A reflecting surface consists of an inner surface and an outer surface, and a filament is disposed along the optical axis of the reflector. The inner surface produces a projection pattern extended in the horizontal direction. The upper half of the inner surface produces a projection pattern below the horizontal center line. Of the lower half of the inner surface, a subsection located on one side of the vertical center plane of the reflector produces a projection pattern contributing to formation of the inclined cutline, and the other subsection located on the other side of the vertical center plane produces a projection pattern contributing to formation of the horizontal cutline. The outer surface produces a projection pattern concentrated in a central area. The upper half of the outer surface produces a projection pattern below the horizontal center line.
Abstract: Disclosed is a vehicular headlamp, which has a reflecting surface curved outward, a lens covering the front of the reflecting surface and a filament disposed at a predetermined position at the reflecting surface, whereby the light emitted from the filament is reflected at the reflecting surface to irradiate a low beam. This headlamp further has an auxiliary reflecting surface provided at a position out of the region which extends from the filament and covers the effective reflecting surface of the reflecting surface. The auxiliary reflecting surface is positioned substantially horizontal and substantially parallel to the irradiation direction. The vehicular headlamp with the above structure can therefore produce beams to illuminate overhead signs from the light reflected at the auxiliary reflecting surface while emitting no dazzling light to an approaching vehicle from the auxiliary reflecting surface. Further, this headlamp does not deteriorate the designability of the lens.

Abstract: A flashlight for providing illumination and indicating energization of the light bulb when the bulb is not visible. The inventive device includes a cylindrical main body having a lens and a light bulb coupled to a first end thereof. A plurality of batteries contained within the main body selectively energize the light bulb to provide illumination. A plurality of indicator lights are mounted about a circumference of the main body and are energized in unison with the light bulb. Thus, when the first end of the flash light is positioned upon a ground surface, the indicator lights serve to alert an individual to the light being left on.
