  • Patent number: 9033564
    Abstract: A high pressure discharge lamp (10), which is particularly a motor vehicle headlight, comprises a high pressure discharge burner (12) for emitting light supported by at least one leg (24), preferably three or four legs (24). By means of the legs (24) the burner (12) is mechanically connected to a socket (14) of the high pressure discharge lamp (10). According to the invention the legs (24) are part of a holder (16), which comprises further a ring (18) surrounding the socket (14), whereby the ring (18) is one-piece with the legs (24). Due to the design of the holder (16) as ring (18) with protruding legs (24) the heat of the burner (12) is conducted from the burner (12) via the legs (24) to the ring (18) by heat conduction. From the ring (18) the heat is led away to the environment by convection. This leads to a significant cooler Temperature of the holder (16) with respect to the burner (12), so that the material of the socket (14) needs not to be selected with respect to a good heat resistance.

  • Patent number: 8253332
    Abstract: An excimer lamp has a single tubular discharge chamber configured to enclose a discharge gas that is a noble gas or a mixing gas consisting of a noble gas and a halogen gas; a pair of electrodes configured to be arranged along opposite sides of the exterior surface of the discharge chamber; and an outer tube configured to cover the discharge chamber and the electrodes. Excimer molecules are produced by either dielectric barrier discharge or capacitive-coupled high-frequency discharge. An interior of a space formed between the outer tube and the discharge chamber is either in a vacuum state that is necessary and sufficient for preventing discharge, or is filled with an arc-suppression gas.

  • Patent number: 8113683
    Abstract: An HID luminaire includes a single luminaire housing that includes thermally isolated lamp and ballast compartments. At least one HID lamp is disposed within the luminaire housing, and at least one ballast is disposed within the ballast compartment. The lamp and ballast compartments are separated by a chamber that includes a substantially nonconductive member, which prevents heat from the lamp compartment from travelling to the ballast compartment. Thermally isolating the ballast from at least a portion of the heat generated by the HID lamp allows the ballast to be disposed relatively close to the HID lamp without becoming overheated and damaged. A hollow, threaded rod extends between and couples together the lamp compartment and ballast compartment. Electric wires connecting the HID lamp and ballast extends through the threaded rod, providing necessary electrical power in an aesthetically pleasing design.

  • Patent number: 8057068
    Abstract: An artificial light source generator includes at least one luminescent set and a projection plane. The luminescent set includes a light source, a parabolic mirror, a supporting seat, a first lens array, and a second lens array. The light source is disposed at the focus of the parabolic mirror, so that light beams generated by the light source are transmitted in a parallel direction through the parabolic mirror. The supporting seat is for supporting the light source. The first lens array has a plurality of first lens units, and each of the first lens units has a first focal distance. The second lens array has a plurality of second lens units. The distance between the second lens array and the first lens array is 0.5 to 1.5 times the first focal distance. A suitable distance exists between the projection plane and the luminescent set, so that the light beams passing through each of the second lens units cover the entire projection plane. Therefore, the projection plane has excellent illumination uniformity.

  • Patent number: 7923908
    Abstract: A novel metal halide reflector lamp is described wherein the reflector lamp has a passive optical element to scramble, color mix, and otherwise commingle the light emitted by the metal halide burner. The optical element is placed close to the radiating plasma volume to intercept a large solid angle. Preferably, the optical element substantially intercepts the emitted light within a solid angle that has its vertex at the center of the discharge volume of the burner and is subtended by the open end of the reflector. The optical element can be designed to scatter, reflect or refract the light emanating in this solid angle which otherwise would not impinge on the primary optical control surface of the reflector.
