| titleOfInvention | High pressure discharge lamp |
| abstract | In the high-pressure discharge lamp according to the present invention, the tip portions of the electrodes 3, 3 arranged facing the inside of the discharge vessel 2 of the arc tube 1 are formed into a substantially hemispherical shape, and a projection that becomes an arc spot at the tip portion. 10 is a high-pressure discharge lamp in which a distance L (mm) between the electrodes 3 and 3 and a stable lighting lamp are used to reliably prevent the occurrence of an arc jump phenomenon in which the arc spot moves cyclically. Relational expression with current I (A): 0.3 ≦ L / I ≦ 1.0, bromide molar amount X (mol) of bromide sealed in discharge vessel 2 and internal volume Y (ml) of discharge vessel 2 Equation 1.2: 1.2 × 10 −7 ≦ X / Y ≦ 1.1 × 10 −5 , Tungsten weight W (mg) of the tip of the electrode 3 formed in a substantially hemispherical shape and the lamp current I (A ) With 9 ≦ W 3/2 / I ≦ 65 and stable lighting The rectangular wave lighting frequency in was set to 45 Hz or more. |
