摘要: The electric lamp has a ceramic lamp vessel (1) having a filling of rare gas and metal halide. Current conductors (2, 3) which support electrodes (4, 5) inside the discharge vessel (1) enter the discharge vessel (1) in a gastight manner through a ceramic sealing compound (6). At least one of the current conductors (2, 3) has inside the lamp vessel (1) a first, halogen-resistant part (21, 31) which is selected from tungsten silicide, molybdenum aluminide, molybdenum boride, pentamolybdenum trisilicide and combinations of at least two of these intermetallic compounds. These compounds have a coefficient of thermal expansion which corresponds to that of the discharge vessel (1). It is thereby prevented that the discharge vessel starts leaking if the ceramic sealing compound (6) extends beyond the first part (21, 31). As a result of their coefficient of thermal expansion, the intermetallic compounds may constitute the second part (22, 32) of the current conductors (2, 3) as well, which part (22, 32) is surrounded by the ceramic sealing compound (6) in a gastight manner.

摘要: A discharge device for operation in a gas at a prescribed pressure includes a cathode having a plurality of micro hollows therein, and an anode spaced from the cathode. Each of the micro hollows has dimensions selected to produce a micro hollow discharge at the prescribed pressure. Preferably, each of the micro hollows has a cross-sectional dimension that is on the order of the mean free path of electrons in the gas. Electrical energy is coupled to the cathode and the anode at a voltage and current for producing micro hollow discharges in each of the micro hollows in the cathode. The discharge device may include a discharge chamber for maintaining the prescribed pressure. A dielectric layer may be disposed on the cathode when the spacing between the cathode and the anode is greater than about the mean free path of electrons in the gas. Applications of the discharge device include fluorescent lamps, excimer lamps, flat fluorescent light sources, miniature gas lasers, electron sources and ion sources.

摘要: In a short-arc high-pressure discharge lamp (1) with a xenon fill for digital projection purposes, the separation L in mm of the two mutually facing end sections (6a, 8c) of the cathode (6) and the anode (8) when the lamp is hot is given by the relationship 0.8×P≦L≦1×P+1, where P is the lamp power in kW. Further, the diameter D of the circular-cylindrical middle section (8a) of the anode (8) in mm obeys the relationship D≧2.1×L+10.

摘要: An apparatus for improving the performance of a ceramic metal halide (CMH) lamp includes an interior chamber (12) disposed within an outer envelope (10). In a preferred arrangement, two legs (14, 16) extend laterally in opposite directions from the chamber. Each leg encloses an electrode/leadwire assembly (22, 24). The electrode/leadwire assembly is constructed from a single continuous piece of wire, preferably tungsten, which forms a shaft or mandrel (50). One end of the mandrel supports an electrode tip (52) which is also preferably made from tungsten. The mandrel also supports an overwind component (54) at a predetermined position. In a desired arrangement, the overwind component is made from molybdenum. The single or one-piece mandrel negates the need for a welded shank assembly resulting in a stronger and more stable lamp that is less expensive to manufacture.

摘要: A high pressure discharge lamp has a pair of electrodes in a discharge tube. Each electrode includes a coil and an electrode rod with a tip, the coil being set around the electrode rod near the tip. The tip of the electrode rod and an adjacent portion of the coil are fused together during the initial discharge. To be more specific, the coil covers the electrode rod near the tip, with the tip of the electrode rod being left uncovered and a length of the tip being &Dgr;L that satisfies an inequality 1/50*R3≦&Dgr;L≦1/5*R3 where R3 is an outer diameter of the coil adjacent to the tip. Alternatively, the electrode can be first formed before being set in the discharge tube, by integrally melting the tip of the electrode rod and the adjacent portion of the coil using, for example, a plasma or laser.
