Definitions

the invention relates to a method for the pulse operation of high-pressure discharge lamps to improve the lighting properties.
the optimal pulse width for sodium vapor discharge lamps is between 100 us and 200 us, so that when using delay chains for pulse shaping, an appropriate electronic ballast would be very complex and voluminous.
the generation of relatively broad pulses with a corresponding height places high demands on the ballast technology, since large amounts of energy have to be stored and switched.
the aim of the invention is to propose a method for the pulsed operation of high-pressure discharge lamps with which good lighting parameters can be achieved and which requires little effort for the ballast technology.
the object is achieved in that the blanking pulses for the high-pressure discharge lamp are formed by pulse groups from bipolar individual pulses with a pulse width of less than 100 us, the repetition frequency of the pulse groups being above 100 Hz at a pulse duty factor below 0.8 and the individual pulses having a frequency above 400 Hz at any duty cycle.
a sinusoidal holding current or direct current is fed in between the pulse groups.
the individual pulses can also be designed as needle pulses.
the frequency of the individual pulses is to be selected so that resonance frequency gaps are used, or it lies above the resonance band of the discharge system.
the mean power fed into the lamp is now essentially dependent on the width of the pulse groups (number and energy of the individual pulses per unit of time) and the repetition frequency of the pulse groups. Even at a very high frequency of the individual impulses, no loss of light yield compared to the key operation with wide impulses is detectable, whereby the lighting parameters such as color temperature and color rendering also achieve identical values.
a sodium vapor high-pressure discharge lamp specially designed for tactile operation is operated with bipolar needle-shaped pulses which are combined into pulse groups.
a sinusoidal current of 80 mA with a frequency of 20 KHz is fed in as a holding load.
the single pulse frequency of the strobe is 3 KHz with a pulse group frequency of 150 Hz and a pulse group width of 1.2 ms.
the needle pulses are generated by capacitor charging or discharging, with no resonance phenomena occurring at a frequency of 3 kHz.
the pulse height was again chosen so that an average color temperature of approx. 3000K is achieved.
