<p>The present invention relates to a lamp driver unit for, in particular, fluorescent lamps. The lamp driver unit comprises an inductive and capacitive output stage which is driven by a microcontroller that controls very precisely the frequency of the signals used or applied to the L/C network. The microcontroller uses a counter and a stable high frequency oscillator to produce a very stable and accurate frequency signal for application to the L/C resonant network which, in turn, results in closely controlled lamp operating parameters. Advantageously, such precise control of the operating frequency results in, for example, significantly improved lamp life, operating conditions, consistent output intensity and colour and significant flexibility in being able to accommodate changes in lamp drive parameters.</p> |
