摘要： To provide a high-efficiency and long-life high intensity discharge lamp that is obtained by a configuration in which a neon gas or a neon-based gaseous mixture is filled as a starting-assistance rare gas for an alumina ceramic arc tube, and a filling pressure is set to 13 kPa or more. The high intensity discharge lamp is provided with the alumina ceramic arc tube (1) having a discharge arc tube (3), alumina ceramic narrow tubes (4,5) formed at both end portions of the discharge arc tube (3), electrodes (6,7) and power feeders (12,13), the electrodes (6,7) and the power feeders (12,13) being arranged to form spaces (17,18) in the narrow tubes (4,5). The discharge arc tube (3) is filled with the neon gas or the neon-based gaseous mixture as the starting-assistance rare gas at a filling pressure of 13 kPa or more. This prevents a discharge arc from jumping from tip portions of the electrodes to the spaces (17,18) at starting of the lamp, and avoids occurrence of cracks and breakages in the narrow tubes (4,5). Therefore, it is possible to offer a high-efficiency and long-life high intensity discharge lamp.

摘要： A metal halide lamp has an arc tube (3) including an arc tube container as an envelope made of an oxide-based translucent ceramic material such as alumina, and the arc tube is filled with cerium halide as a luminescent material (17) and a halide of a rare earth element that is more reactive with the ceramic material than is the cerium halide. Accordingly, a reaction between the oxide-based translucent ceramic material and the halide of a rare earth element is accelerated while a reaction between the oxide-based translucent ceramic material and the cerium halide is suppressed. This suppresses a decrease of the cerium halide that serves for light emission, and also reduces changes in the lamp color temperature. Thereby, lowering of flux maintenance factor and color temperature in aging of the lamp are suppressed, and the thus provided metal halide lamp with an alumina ceramic tube for indoor and outdoor use has a white light source color and it has a high-wattage, high luminous efficiency, and a long service life.
