Abstract: A lighting fixture comprising a reflector 100 and a double-ended elongate lamp 200, the reflector body comprising a casing (110) with a specular cavity having an apex and an aperture rim, wherein the lamp end portions (220, 220?) of the double-ended lamp are enclosed in slots (131, 131?) located in the casing at opposite sides of the aperture rim and substantially flush with the aperture rim, is extremely flat and slim and therefore useful as a recessed down-light in a shelf, a ceiling, or a wall panel.

Abstract: A halogen lamp includes a mains base and a converter operably connected to the mains base. The converter has a lamp socket, a toroid transformer, and a heat sink disposed within a center opening of the toroid transformer. A lamp is removably disposed in the lamp socket. The converter has a power density between 0.75 and 3.75 Watts/cm3. In an alternate embodiment, the halogen lamp includes a low voltage, low pressure IRC lamp operably connected to the converter.

Abstract: An electric lamp has an outer lamp envelope (1) enclosing a light-transmitting inner lamp vessel (2) in a gastight manner. A light source (3) is arranged in the inner lamp vessel. An optical interference film (4) is provided on at least part of an inner surface of the outer lamp envelope or on at least part of an outer surface of the inner lamp vessel. The optical interference film comprises a plurality of alternating high and low refractive index layers, the material of the high refractive index layer comprising substantially zirconium oxide. Preferably, the ratio of the volume Vilv of the inner lamp vessel to the volume Vole outer lamp envelope (1) is: Vilv/Vole?0.5, preferably ?0.25.

Abstract: A halogen lamp (28) includes a mains base (34); a converter (32) operably connected to the mains base (34), the converter (32) having a lamp socket (38); and a lamp (36) removably disposed in the lamp socket (38); wherein the converter (32) has a power density between 0.75 and 3.75 Watts/cm3. In an alternate embodiment, the halogen lamp (28) includes a mains base (34), a converter (32) operably connected to the mains base (34), and a low voltage, low pressure IRC lamp (36) operably connected to the converter (32).
