摘要： PROBLEM TO BE SOLVED: To provide a starting auxiliary means with no mercury contained and to consequently provide a means capable of making a metal halide lamp perfectly not contain mercury. SOLUTION: The starting auxiliary means is constituted of a UV permeable capsule having a cavity in which iodine and inactive gas is sealed, and at this time, when the iodine is excited, it emits a UV ray and lowers starting voltage of the lamp.

摘要： PROBLEM TO BE SOLVED: To provide a high-transmittance polycrystalline alumina light emitting tube (10) for a metal halide discharge lamp by treating an alumina light emitting tube material having several % of closed cells by two-stage processes. SOLUTION: The starting porous light emitting tube is formed by extruding or die pressing light emitting tube parts consisting of an alumina powder-containing mixture, integrating the parts to form a light emitting tube body and partially sintering the light emitting tube body to hermetically seal the parts to each other. Two-stage processes including stages of hot isotropic pressurization of the partially sintered light emitting tube and chemically polishing the light emitting tube surface is carried out. The first pressurizing stage includes a stage of heating the alumina light emitting tube for about one to three hours at and under temperature of 1,600 to 1,900 deg.C and pressure of about 700 to 2,100 kg/cm under an inert atmosphere, thereby lowering the porosity of the crystalline structure of the alumina light emitting tube. In the second stage, the light emitting tube surface is immersed into a molten alkaline metal borate-containing flux at an adequately high temperature or is coated with the flux material and is heated to form the flux, by which the surface defects are removed. The transmittance of the light emitting tube is approximately comparable to the transmittance of a single crystal sapphire light emitting tube.

摘要： A short-arc high pressure discharge lamp with a shorter distance between electrodes than a conventional lamp that realizes a long life of at least 3000 hours and suppresses the arc jump phenomenon is disclosed. In the high pressure discharge lamp, an electrode tip 124 is transformed into a semi-sphere by fusing and processing an electrode rod 122 and a coil 123 wound around an end of the electrode rod 122. A thickness "de" and a diameter " phi e" of the semi-sphere are each set in a range predetermined in correspondence with a power input (W) of the short-arc high pressure discharge lamp.

摘要： A high pressure mercury ultraviolet lamp with high dimensional accuracy in which the emitter material during lamp operation is prevented from spraying and being deposited onto the wall of the discharge vessel and the UV radiation transmission factor is prevented from being reduced is achieved by the fact that at least one of a group of halides which consists of halides of yttrium lanthanum, cerium, dysprosium, gadolinium and thorium and at least one of a group of halides which consists of halides of alkali metal elements are filled at a filling ratio in the range from 1:4 to 1:20 to one another as a molar fraction. This also yields the same action as the application of emitter material to the upholding parts of the electrodes. Furthermore, high dimensional accuracy can be ensured by the measure by which the discharge vessel is made of a translucent ceramic, such as YAG.

摘要： PROBLEM TO BE SOLVED: To provide a high-pressure discharge lamp exhibiting a sufficiently low ignition voltage, and a lighting device and an illuminating device of the high pressure discharge lamp using it. SOLUTION: The high-pressure discharge lamp includes a light transmitting discharge vessel having an enveloping portion and a pair of small diameter cylindrical portions with a small size communicated with both ends of the enveloping portion; a light emitting tube having a pair of electrodes and a discharge medium; a metallic coil wound around a circumference of at least one of the small diameter cylindrical portions and connected to an opposite electrode at one end to have the same electric potential; an outer tube receiving the above elements in an airtight manner; and a pair of external connection terminals connected to the light emitting tube and led out from the outer tube in the airtight manner. The metallic coil is preferably wound for four turns or more, and one end of the metallic coil is placed in the vicinity of a boundary on the enveloping portion. A winding pitch of the metallic coil is 100% to 50%, and the length L2 of the coil is 0.3 to 1.0 times over a length L1 of the small diameter cylindrical portion, and the coil end opposite to the enveloping portion is connected to the opposite electrode to have the same electronic potential.
