Abstract
The invention describes an ignitor arrangement (1) for a high-intensity discharge lamp (2), which ignitor arrangement (1) comprises a first pair of input terminals (101, 102) for applying an ignition voltage to the ignitor arrangement (1); a second pair of input terminals (101, 103) for applying an input drive voltage to the ignitor arrangement (1); and a discharge resistor (10) arranged in the interior (100) of the ignitor arrangement (1) and connected across the first input terminal pair (101, 102), which discharge resistor (10) is realised as a temperature-dependent resistor (10). The invention also describes a lamp driver (3) realised to drive a high-intensity discharge lamp (2); a lighting arrangement (4); and a method of driving a high-intensity discharge lamp (2).
Claims15
-15. (canceled)
An ignitor arrangement for a high-intensity discharge lamp, which ignitor arrangement comprises
- a first pair of input terminals for applying an ignition voltage to the ignitor arrangement;
- a second pair of input terminals for applying an input drive voltage to the ignitor arrangement;
- and
- a discharge resistor arranged in the interior of the ignitor arrangement and connected across the first input terminal pair,
- characterized in that
- the discharge resistor is realised as a temperature-dependent resistor, and in that
- a resistance of the discharge resistor relates to a temperature (T100) in the interior of the ignitor arrangement.
