摘要:
A lighting apparatus including a reflector having a reflective surface partially enclosing an interior space and defining a focal point within the interior space, and a filament positioned substantially within the interior space. In some examples, the filament is made substantially of tungsten. In some examples, the reflective surface extends along a longitudinal axis and curves around the longitudinal axis. In some examples, the reflective surface defines an elliptical paraboloid. In some examples, the filament may be placed substantially at the focal point of the reflective surface.

The invention relates to a vehicle headlight bulb with a bulb receptacle, a spiral wound filament (2) which is arranged inside the receptacle for the bulb (1) and a lamp base which has a metal base bushing (3) wherein the end (11) of the bulb receptacle (1), which is sealed by means of a molybdenum film seal (112, 113) is fixed. According to the invention, the metal base bushing (3) comprises at least one molded tab (32) which lies adjacent to the sealed end (11) of the bulb receptacle (1), in the overlapping area of the molybdenum films (112, 113), with current supply wires (23, 24) which protrude from the bulb receptacle and which are connected thereto, in order to reduce thermal load in the above-mentioned overlapping area during operation of the bulb.

The present invention comprises a method of enhancing illumination by a variety of lamp types through the use of reflective technologies, for example, replacement of expensive high intensity density of mercury vapor lamps with low wattage fluorescent tubes having at least one and in some cases, up to three reflective surfaces for focusing otherwise lost light toward a target illumination area. Further, the placement of light sources at the focal point of said reflective surfaces aids in optimizing the amount of light focused in a desired direction.

A lamp (1, 11, 14, 17) for a motor vehicle headlight is described. The lamp (1, 11, 14, 17) comprises a bulb (3) surrounding a light source (4) and a lamp base (2) arranged at an end of the bulb (3) and serving to support the lamp (1, 11, 14, 17) inside a reflector (20) of the headlight. At least one lens structure (7, 12, 15, 18) is present in or at an upper side (O) and/or lower side (U) of the bulb (3). This lens structure (6, 12, 15, 18) is constructed such that at least a portion of the light radiated by the light source (4) in the direction of a region of the reflector (20) close to the lamp base is redirected into a region of the reflector lying farther to the front.
摘要:
A composition for the manufacture of an opaque silvery coating on a glass surface is provided. The composition comprises a mixture of at least two metal powders. The metal powder mixture contains carbonyl iron and aluminum, and a carrier liquid for forming a suspension of the metal powder mixture. A method for manufacturing an opaque silvery coating for a lamp having a glass envelope is also provided. In the method, a suspension comprising a mixture of carbonyl iron and aluminum powders in a carrier liquid is applied onto the envelope of the lamp. The suspension is dried, and thereafter the composition remaining from the suspension is burned at a temperature above 500° C. A lamp with a glass envelope and a single layer opaque coating covering at least a part of the glass envelope is also disclosed. The opaque coating comprises 50 to 80 weight % carbonyl iron and 20 to 50 weight % elementary aluminum.
摘要:
A filament comprises a generally thin metal component, such as a sheet, ribbon, or foil. The filament comprises at least one emitter, at least one current-condensing structure and a tab on each end of the at least one emitter. Each tab is connectable to a support system, comprising for example a lead and attachment post. When a current is passed through the filament, the current-condensing structure establishes current flow through the filament resulting in a desired temperature distribution across the emitter, for example a substantially uniform temperature distribution. A predictive tool for determining a geometry of a filament to provide a desired temperature distribution is set forth. The filament may be curved, and methods and systems for providing a curved filament are also provided. Attachment systems are further disclosed for attaching an emitter to a support structure.

A lamp configuration particularly for infrared radiation provides an internal arrangement and environment adapted to overcome failure modes of prior art broad band infrared sources, and may incorporate optical elements including spectral filters and lenses enabling wavelength selection, beam shaping, external focusing, collimating, and wave front shaping. It also facilitates optical coupling to external devices including a rotating mirror, shutter and modulator devices.
