A lighting apparatus including a reflector having a reflective exterior surface partially enclosing an interior space and defining a focal point within the interior space, and a high pressure discharge lamp positioned substantially at the focal point of the reflective exterior surface. In some examples, the high pressure discharge lamp includes an arc tube containing mercury, a metal halide, or sodium. In some examples, the reflective exterior surface extends along a longitudinal axis and curves around the longitudinal axis. In some example, the reflective exterior surface defines an elliptical paraboloid.

Lighting apparatuses that include a reflector attached to an adjustable support, a reflective surface on the reflector that defines an interior space and a focal point within the interior space, a light source partially disposed within the interior space and positioned substantially near the focal point, wherein the light source is configured to generate light by passing an electrical current through the lighting element. In some examples, the adjustable support defines a flexible stem. In other examples, the adjustable support defines a collection of bars rotatably connected at pivot points.

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 lighting system comprising a lighting apparatus and a lighting adapter, where the lighting adapter includes a frame, a curved reflector coupled to the frame and having a reflective surface partially enclosing an interior space and defining a focal point within the interior space, a light source disposed at least partially within the interior space and substantially at the focal point of the reflective exterior surface, wherein the light source is electrically wired to allow current to flow from an outside power source into the light source, a pair of endcaps, the endcaps centering the light source substantially at the focal point, and a pair of tombstone sockets, and where the lighting adapter includes a plurality of grooved channels, wherein the grooved channels of the lighting adapter are transversely disposed on each end of a rear-wall member,

The invention relates to a headlight lamp having at least one lamp vessel (1) in which at least one luminous means (2, 3) is enclosed, and having a lamp base (9) which is provided with the electric terminals of the headlight lamp. The lamp base (9) has an annular metallic holder (8, 10) in which the at least one lamp vessel (1) is fixed, and at least three reference noses (11a, 11b, 11c) arranged in a common plane, as well as an annular base flange (12), the base flange plane being arranged parallel to the plane of the reference noses (11a-11c), and the base flange (12) being provided with at least three lugs (12a, 12b, 12c), which are arranged along its circumference, are of resilient design and serve together with the reference noses (11a, 11b, 11c) for fastening the lamp in a headlight. According to the invention, the reference noses (11a, 11b, 11c) are integrally formed on a reference ring (11) which is connected to the annular metallic holder (8, 10) and to the base flange (12), and which has a flat annular surface (11d) arranged parallel to the base flange plane, the outside diameter of the annular surface (11d) being greater than or equal to the inside diameter of the base flange (12) and greater than or equal to the outside diameter of the annular metallic holder (8, 10), and the inside diameter of the annular surface (11d) being smaller than the inside diameter of the base flange (12) and smaller than the outside diameter of the annular metallic holder (8, 10).

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.

A reflector lamp, in particular a halogen reflector lamp, has a light-transmitting lamp vessel, in which at least one luminous member is accommodated, at least one vessel section of the lamp vessel being provided with a reflective coating. According to the invention, the reflective coating has an interference filter, which is substantially impervious to light in the visible wavelength range and has defined transmission and reflection properties for light in the infrared wavelength range.

A partially coated lamp capsule (212) for a projection headlamp (12) has filament (224) in capsule envelope (220) having light-transmissive coating (60) extending from capsule upper region (225) towards filament distal end (227) to an axial location in a region defined between about 0.098 inch (2.5 mm) above filament distal end (227) and about 0.098 inch below filament distal end (227), the capsule envelope (220) being uncoated on an undistorted portion of capsule envelope (220) below filament proximal end (229). Lamp capsule (212) is useful in projection headlamp (12) having a reflector (28) whose central heel (37) forms the hot spot and casts light through projector lens (30) to generate low and/or high beam patterns. Present lamp capsules (212) give increased photometric intensity over conventional lamps in low beam at critical driver's lane (0.6D, 1.3R) and (0.86D, V) test points, and in high beam at the critical (H,V) test point.

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.
