  • Publication number: 20090295308
    Abstract: High-pressure discharge lamps can only be restarted in the hot state at a very high starting voltage. In order to avoid hotstarting, a method for operating high-pressure discharge lamps without hotstarting comprises two high-pressure discharge lamps (12a, 12b) being provided in one luminaire. The two high-pressure discharge lamps are driven as follows: When the luminaire is switched off, the first lamp is switched off, and the second lamp is set to be in a standby state for the period of time for the recovery of the first lamp or remains in such a state, in which it is not switched off. When the luminaire is switched on again during this period of time, the second lamp can assume the operating state again immediately without being started. If the luminaire is not switched on again, the second lamp is likewise switched off once the period of time has elapsed.
