摘要： An apparatus and method for obtaining short-term color stability in an HID lamp, the apparatus comprising in a first embodiment a high intensity discharge lamp with a discharge vessel and electrodes; with a filling within the discharge vessel containing a metal halide dose of at least 20 mg/cc, where volume is defined as the volume of the main cylindrical section of the discharge vessel. In a preferred embodiment, the filling within the discharge vessel contains Hg of at least 20 mg/cc, where volume is defined as the volume of the main cylindrical section of the discharge vessel. In a yet further aspect, the resulting color temperature is stabilized independent of the shape and frequency of the current and voltage waveforms that drive the HID lamp.

摘要： A high pressure sodium lamp (100) having an evacuated glass envelope (6) with a plurality of electrically conductive support members therein and extending therethrough. An elongated arc tube (14) having a pair of electrodes (26) extending therethrough is affixed to the electrically conductive support members within the glass envelope. A gas fill includes a quantity of mercury and sodium within the elongated tube. The arc tube is selected from a translucent material that, when the lamp is operating, will have a wall temperature of about 1250 degrees Celsius, a wall loading of from about 18.9 to about 22.2 w/cm sqr., and a power consumption of from 150 to 400 watts. Further, the amount of mercury is reduced from 14.4 mgs/arc tube to 10.8 mgs/arc tube, allowing lamps having power consumption from 150 to 400 watts to pass the Toxicity Characteristics Leaching Procedure (TCLP).

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 “&phgr;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.
