| Title: | HIGH-PRESSURE GAS DISCHARGE LAMP HAVING ELECTRODE RODS WITH CRACK-INITIATING MEANS | |||||||||||
| Abstract: | A high-pressure gas discharge lamp having a bulb (1) of quartz glass and two electrode rods (8,9), wherein one end of each electrode rod (8,9) is connected to a molybdenum foil member (6,7) embedded in the quartz glass material, while the other end of each electrode rod projects into the gas discharge space (2) inside the bulb (1). A portion of the electrode rod (8,9) is embedded in the quartz glass material of the bulb (1). The surface of said embedded portion of the electrode rod (8,9) is provided with means (14) for initiating cracks (18) at predetermined locations in the quartz glass material surrounding the electrode rod (8,9) during manufacture of the lamp. | |||||||||||
