20090058300 | Short metal vapor ceramic lamp - A high intensity arc discharge lamp having a short metal seal plug running hotter than typical of capillary seals, enables a lamp with a metal fill to achieve a vapor pressure higher than the one set by the cold spot temperature typically of a capillary seal lamp. Corrosive fill materials, such as halogens are excluded. Zinc may be used to in starting the lamp. | 03-05-2009 |
20090072740 | Hid lamp with rapid relight aid - The restrike time for re-light up of an arc discharge lamp may be decreased by including at least one refractory bimetallic start up electrode that provides a shorter arc path intermediate the main arc path in a cool state, but when heated withdraws to have a relatively longer arc path. The longer arc path in the hot state results in a relatively higher path impedance that can be used by itself or in combination with a supplemental impedance device to extinguish the starting arc in favor of the main arc. The withdrawn bimetallic starting electrode then does not interfere with the main arc function. | 03-19-2009 |
20090085455 | Metal Halide Reflector Lamp with Beam Color Homogenizer - 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. | 04-02-2009 |
20090284153 | CERAMIC DISCHARGE LAMP WITH INTEGRAL BURNER AND REFLECTOR - A ceramic discharge lamp and a method of making the lamp includes a ceramic discharge chamber with two concave parts that are attached to each other at a seam, and a ceramic reflector directly attached to an exterior surface of the discharge chamber at the seam, or directly attached to a ceramic capillary that is attached to one of the two concave parts. The lamp finds particular application where focused light is required, such as injection of light into a fiber optic device. The lamp can be very small and has an advantage that the discharge chamber is isolated from the reflective surfaces so that the optically active parts of the reflector are not covered with salt from the preferred metal halide lamp fill. | 11-19-2009 |
20100067241 | Optical Disk For Lighting Module - An optical disk for use in converting light emitted from a light-emitting diode chip to white light. The optical disk includes a tapered surface such that a center area of the disk has a width greater than a width of an outer area of the disk. The optical disk is formed of a silicone having at least one weight percent mix of phosphor. Various embodiments of this generally described optical disk are also presented. | 03-18-2010 |
