摘要： A driver (10) for driving a gas discharge lamp (11) comprises at least two controllable switches (M1, M2) and a controller (12) for controlling the switches. The controller has a first operative state in which one switch (M1) is conductive while the other switch (M2) is non-conductive, and has a second operative state in which said other switch (M2) is conductive while said first switch (M1) is non-conductive. The controller comprises a memory device (20) comprising a plurality of memory elements (21) each containing a binary value (“0”; “1”), wherein the value of the last memory element (21(N)) determines the operative state of the controller. Responsive to a clock signal (SQL) generated by a clock device (30), the memory device shifts the contents of each memory element (21(i)) to a subsequent memory element (21(i+1)) and shifts the contents of the last memory element (21(N)) to the first memory element (21(1)).

摘要： A low-cost HID lighting system (100) comprises: —an HID lamp (1) having an aspect ratio less than 6; and —a resonant electronic driver (10) for driving the HID lamp, the driver being designed for providing alternating current to the lamp and including a control device (30) for determining the current frequency. The lamp has a frequency spectrum containing at least one arc-shaping acoustic resonance frequency as well as unwanted acoustic resonance frequencies. During normal operation, the lamp is provided with frequency-modulated lamp current so that the lamp current has a relatively broad power spectrum within a range between kHz and 200 kHz, so that said arc-shaping acoustic resonance is triggered while said unwanted acoustic resonances are avoided, irrespective of lamp orientation.

摘要： A method of igniting a gas discharge lamp (2) comprises the steps of first applying a plurality of high-voltage ignition pulses with a relatively low amplitude and subsequently applying high-voltage ignition pulses with a relatively high amplitude. Switching over from generating low-amplitude ignition pulses to generating high-amplitude ignition pulses may be done on the basis of counting the low-amplitude ignition pulses or on the basis of monitoring the duration of the period during which the low-amplitude ignition pulses are generated.
