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 headlight lamp has at least one lamp vessel in which at least one luminous element is enclosed, and a lamp base, which is provided with the electric terminals of the headlight lamp. The base has an annular metallic holder in which the at least one lamp vessel is fixed, and at least three reference noses arranged in a common plane, and an annular base flange arranged parallel to the plane of the reference noses. The base flange has at least three lugs are arranged along its circumference, which are of resilient design and serve together with the reference noses for fastening the lamp in a headlight. The reference noses are integrally formed on a reference ring, which is connected to the annular metallic holder and to the base flange.

The invention relates to a lamp (8), in particular a vehicle lamp, having a base (17), a burner (7) having a light-generating element (11, 12), and an adapter plate (1) having a connecting region (2) and a receiving portion (3), the connecting region (2) being connected to the base (17) and the receiving portion (3) to the burner (7). The adapter plate (1) has cutouts (4) between the connecting region (2) and the receiving portion (3) such that the connection region (2) is no longer rigid but has a certain flexibility.

Disclosed is a reflector lamp, particularly a halogen reflector lamp, comprising a translucent lamp receptacle in which at least one luminescent means is accommodated. At least one section of the lamp receptacle is provided with a reflective coating encompassing an interference filter which is substantially impermeable to light in the visible wavelength range while featuring a defined transmission and reflection behavior towards light in the infrared wavelength range.

The invention relates to an electric incandescent lamp, in particular a vehicle headlight lamp, having an incandescent filament(3), arranged inside a transparent lamp vessel(1), and supply leads for the incandescent filament, at least one of the supply leads(4,5) being provided with at least one reinforcing strut(8) in order to improve the vibration strength of the lamp.

An electric lamp (1) according to the present invention is so constructed that it comprises a bulb (2) comprising a first curved face (10), the first curved face having a substantially ellipsoidal shape in cross section with a first focal point (F1) and a second focal point (F2), and being convex outwardly, and a filament (6) comprising a coil part (16) formed by winding a wire and generating a light by being energized, the filament being so arranged that the coil part (16) is positioned in an inner space (5) of the bulb (2), wherein a reflective coating is formed on the whole of outer surface or the whole of inner surface of the first curved face (10), and wherein the first curved face (10) is so adapted that the first focal point (F1) is positioned at the coil part (16), and the second focal point (F2) is positioned at a light transmission medium (20) to which an emerged light generated at the coil part (16) and reflected on the first curved face (10) is provided.

Lighting apparatuses including a first endcap including a first light socket, a second endcap spaced from the first endcap including a second light socket, reflector rotatably attached between the first endcap and the second endcap, the reflector including a reflective surface partially enclosing a reflector interior space and defining a focal point within the reflector interior space. The first light socket and second light socket are collectively configured to support light sources substantially near the focal point. The first endcap and the reflector include complimentarily configured interlocking members.

The invention relates to an electric incandescent lamp, in particular a vehicle headlight lamp, having an incandescent filament, arranged inside a transparent lamp vessel, and supply leads for the incandescent filament, at least one of the supply leads being provided with at least one reinforcing strut in order to improve the vibration strength of the lamp.

The invention relates to an incandescent lamp for vehicle headlights, the incandescent lamp having at least one incandescent filament and a shading apparatus for the at least one incandescent filament, which are both arranged in a lamp vessel, and having power supply lines for the at least one incandescent filament, a first power supply line being connected to the shading apparatus. The abovementioned power supply line has a bent-back end, which is connected to an outgoing filament line of the at least one incandescent filament.

The infrared irradiation lamp comprises: a lampshade (S) made of a lamp housing (12) and a front lens (14), a reflector (16) arranged in the lamp housing (12), a reflector (16) inserted and connected to the reflector ( 16) the bulb is inserted in the connection hole (13) and the bulb (20) arranged in front of the reflector (16), and a bulb (20) which is arranged to cover the bulb (20) and is used to shield visible light and only pass through infrared light for generating A cylindrical sphere (30) of infrared light, wherein a heat sink (68) extending to the back of the reflector (16) is set between the bulb insertion hole (13) and the socket piece (21) of the bulb (20) ) metal bulb holder (60). The heat produced when bulb (20) is energized is transferred to bulb holder (60), and dissipates to the space formed behind reflector (16) from the heat sink (68) that is arranged on reflector (16) back, makes the heat Not stuffy inside the sphere (30). Therefore, it is possible to avoid various problems caused by temperature rise of the bulb (20) and the sphere (30) for generating infrared light.

A filament array for an incandescent lamp comprises a plurality of helically-coiled filament sections (7-10), which are arranged in one or more planes. The filament sections are of varying lengths whereby the array approximates the cross-sectional shape of the light beam which is to be projected by the lamp, as indicated for example by the circle (11).

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.
