Abstract: A high pressure discharge lamp includes a quartz glass bulb, a conductive element which is sealed at a sealing portion of the bulb, and a pair of electrodes. Each electrode is disposed in the quartz glass bulb so as to be opposite the other and connected to the conductive element. A part of each electrode is sealed with the quartz glass bulb at the sealing portion so as to generate a contacting portion formed by the part of each electrode and the bulb. The maximum length, Lmax, of the contacting portion is defined as: Lmax (mm)null200/(PnullD); and the minimum length, Lmin, of the contacting portion is defined as: Lmin (mm)null0.8/(D2nullnull) or Lmin (mm)null0.7 whichever is longer, where D is the diameter (mm) of the electrode and P is the power (W) supplied to the electrode.

Abstract: A high pressure discharge lamp includes a quartz glass bulb having a sealing portion; and a pair of electrodes. Each electrode of the pair of electrodes is disposed so as to be opposite the other in the quartz glass bulb. The quartz glass bulb of the high pressure discharge lamp contains at least mercury and a halogen gas. The partial pressure of oxygen (O) in the quartz glass bulb is about 2.5null10null3 Pa or less and the partial pressure of the halogen gas in the quartz glass bulb is in the range between about 1null10null8 nullmol/mm3 and 1null10null7 nullmol/mm3.

Abstract: A high pressure discharge lamp includes a quartz glass bulb and a pair of electrodes. Each electrode of the pair of electrodes is disposed so as to be opposite the other in the quartz glass bulb. The quartz glass bulb of the high pressure discharge lamp contains at least mercury and a halogen gas which are airtightly sealed in the quartz glass bulb. The partial pressure of oxygen (O) in the quartz glass bulb is about 2.5null10null3 Pa or less and the partial pressure of the halogen gas in the quartz glass bulb is in the range between about 1null10null6 nullmol/mm3 and 1null10null8 nullmol/mm3. The pair of electrodes contain potassium oxide in the range between about 20 ppm and 40 ppm.
