A housing holds embedded in arrayed order along an axis (i) a conical first omni-directional reflector, (ii) a directional second reflector and a second LED, (iii) a directional first reflector and a first LED, and (iv) a conical second omni-directional reflector. Light from the first (second) LED as is in part reflected by the directional first (second) reflector is omni-directionally dispersed by the first (second) omni-directional reflector. All reflectors optionally serve as electrical connections to the LED's. A linear light constructed as a chain of these omni-directional LED lamps wired in electrical parallel may be easily cut to length. Other two and three-dimensional omni-directionally-illuminating lighting fixtures are possible, such as in the shape of crosses and stars and the six-pointed metal object used in the game of jacks.

A reflector apparatus for reflecting light produced by a flash light apparatus such as a flash bulb, an electronic flash apparatus or the like, comprises a sealable container capable of tightly containing a gas therein. The container is in the form of a substantially spherical configuration when inflated and is made of a soft and flexible material, a half portion of which is transparent while the other half portion reflects light. The light rays from the flash apparatus are transmitted through the transparent portion and are reflected by the reflecting portion toward an object to be illuminated.

A cup-shaped reflector has a larger open end and a smaller open end. A diffuser glass closes off the larger open end. A lamp is comprised of a lamp bulb having a fused, squashed-flat rear portion hermetically sealing the interior of the bulb, with a plurality of lamp electrodes passing through the squashed-flat rear portion of the lamp bulb and embedded within the material of the squashed-flat rear portion of the lamp bulb. A plurality of lugs is provided, each connected to one of the lamp electrodes at the rear of the lamp, in electrically conductive engagement with the electrodes. A mounting arrangement mounts the lamp bulb on the reflector in the region of the smaller open end of the reflector with at least part of the lamp bulb projecting forwardly into the interior of the reflector.

Fluorescent lighting apparatus utilizing a single elongated fluorescent tubular light source replaces the multiple fluorescent tubular light sources of conventional or prior art fluorescent lighting apparatus. A substantial savings in energy consumption and cost of replacement fluorescent tubular light source units results. A substantial part of the light output of the fluorescent tubular light source is reflected by an improved reflector construction having multiple elongated strip-like mirror surfaces formed of a film base having a silver coating, the mirror surfaces being arranged to direct the reflected light of the single fluorescent tubular light source over a relatively wide area whereby it appears that a greater number of fluorescent tubular light sources are provided.
摘要:
Two concave reflector portions (22a, 22b) confront each other and have narrow ends (14) which overlap. The reflector portions widen from respective beam-emission axes (13) to their wide ends (16). The beam-emission axes are oppositely-directed. The apparatus has beam-emitting apertures (18) at the wide ends. A bulb (24) disposed between the overlapping narrow ends of the reflector portions produces two mutually divergent light beams, by reflection off the reflector portions.
摘要:
A slit illuminating device of a compact size which is capable of performing effective illumination on an image original having a certain amount of thickness such as books, bound documents, etc., the surface of which slightly separates off an original image mounting table when it is placed thereon with its surface to be illuminated being faced down to the table, and which is also capable of uniformly illuminating a slit portion irrespective of slight positional displacement of a light source, whereby the image original can be broadly illuminated with divergent rays from an oblique lower direction in a substantially symmetrical manner.

An asymmetrical lamp has a main lens (2), a reflector (3) and at least one light source arranged between the reflector (3) and the main lens (2). In order to achieve a uniform illumination of all areas of an object, even when the lamp is not positioned on an axis extending 90.degree. to the object, the light source (1) and the reflector (3) are offset from an optical axis (6) of the main lens (2). The main axes (4, 5) of the light source (1) and the reflector (3) are, further, inclined to the optical axis (6) of the main lens (2). Preferably, the offset of the light source (1) and the reflector (3) relative to the optical axis (6) of the main lens (2), and the inclination of the main axes (4, 5) of the light source (1) and the reflector (3) to the optical axis (6) of the main lens (2), is adjustable so that the lamp can be optimally adjusted.
摘要:
A lighting fixture substantially comprising a lamp housing and an illuminant disposed therein, with a transparent decorative body being provided below the illuminant and spaced from the lamp housing, and a plate reflective on the side facing away from the illuminant and having a central bore being disposed between the illuminant and the decorative body.
摘要:
An indirect lighting system includes a housing which defines an outwardly facing reflector. Coupled centrally to the reflector and spaced therefrom is a removable shield which, in one embodiment of the present invention, covers a light mounted to the center area of the reflector, and in another embodiment of the present invention, includes the light source itself. The light positioned behind the shield in either embodiment is reflected by the relatively large area defined by the reflective housing.
摘要:
Lighting apparatus having less than the conventional number of light sources, but which provides illumination substantially equivalent to the illumination provided by the conventional apparatus, thereby providing savings in energy consumption and in cost of operation. Part of the light output of the light sources which are provided is reflected to illuminate areas of the diffuser plate which are illuminated by additional light sources in conventional apparatus, whereby it appears that a full number of light sources are provided when in fact less than a full number of light sources are provided.
