High-pressure discharge lamp, high-pressure discharge lamp lighting device and automotive headlamp apparatus |
摘要 |
The present invention provides a high-pressure discharge lamp that uses substantially no mercury and reduces discharge flicker. The high-pressure discharge lamp is kept on with a lamp power of 50 W or lower in a stable state, and the temperature T (° C.) of the electrode at a point at a distance of 0.3 mm from the tip end to the base end in the stable state and the amount A (mol/cc) of free iodine produced when the lamp is turned off after 100 hours of on-time satisfy the formula (1):T<SUP>2</SUP>/A>10<SUP>11</SUP>.
