摘要： A triac dimmable compact fluorescent lamp including a power feedback circuit. The power feedback circuit helps to maintain the level of current drawn from the triac to at least the level of the triac holding current especially during low dim levels. In one preferred embodiment, the feedback circuit is fed into a junction joining together a pair of fast recovery diodes for converting the high frequency square wave signal into a unidirectional signal supplied to an inverter. Overboost voltages across a buffer capacitor are minimized during low dim levels.

摘要： A controller for operating a gas discharge lamp to detect arc instabilities includes operating the lamp at a plurality of operating frequencies and recurrently sensing an electric lamp parameter to determine a stability factor for each frequency. While operating at each frequency, a deviation in the sensed electrical parameter is determined, which is used to calculate the stability factor, which is inversely proportional to the determined deviation. The lamp is operated for longer durations at frequencies having higher stability factors than at frequencies having lower stability factors.

摘要： The invention relates to a discharge lamp equipped with a gastight discharge vessel that contains a filling that comprises a gas, that is transmissive for at least part of the electromagnetic radiation that is generated by the filling during operation and is equipped with lamp electrodes between which a discharge is maintained during operation. In accordance with the invention the discharge lamp comprises a piezotransformer and at least one of the lamp electrodes comprises a secondary side of the piezotransformer. Since the piezotransformer functions as a lamp electrode, as a ballast choke and as a transformer, the discharge lamp can be operated by means of a relatively simple and cheap ballast circuit.

摘要： The invention relates to a method for producing series of impulse voltages to operate discharge lamps (8) by means of pulsed, dielectrically impeded discharge. According to said method, the series of impulse voltages consists of two series of partial voltages so that the total peak values of each series of partial voltages is lower than the total peak values of the resulting series of impulse voltage e.g. half as big. One advantage is that correspondingly lower EMI arises when the series of partial voltages are produced. Also both series of partial voltages have opposite inclined rising edges in relation to a reference potential. Preferably, both series of partial voltages are inverted. This provides ideal and full compensation, at least locally, of electromagnetic interference (EMI) produced by both series of partial voltages. A circuit thus includes two series connected impulse circuits (1; 2) which are synchronised using a timing circuit (3).

摘要： A circuit arrangement according to the invention for operating a discharge lamp (I) comprises a self-oscillating DC/AC converter (II) provided with a series arrangement A of a first and a second switching element (1, 1', respectively) between a first and a second input terminal (2, 2', respectively) for the connection to a DC voltage source (III). The series arrangement A supplies an alternating current Ib to a load branch having output terminals (6a, 6b) for connection of the discharge lamp (I) during nominal operation. The circuit arrangement according to the invention is in addition provided with a starter circuit ST comprising means (15, 12') for generating a DC voltage component between the control electrode (1c') and the main electrode (1a') of the second switching element (1'). The starter circuit ST is also provided with means M which comprise an auxiliary switch (25). The means M bring the first switching element (1) into a conducting state if the amplitude of the alternating current Ib is low compared with the amplitude during nominal operation. The means M counteract damage to the switching elements (1, 1') and promote the initiation of the nominal operational state.

摘要： A dimming interface for translating the conduction pulse width of a signal produced by a triac dimmer into a proportional rectified average voltage serving as a dimming signal. The dimming signal is supplied as an input to an IC driver in controlling the level of lamp illumination. The proportional rectified average voltage can be converted into a signal representing a duty cycle whereby variation in the main line voltage does not affect the dimming signal.

摘要： A fluorescent lamp ballast having an integrated circuit driver which avoids lamp flicker caused by momentary dips in mains voltage during lamp turn on. The anti-flicker scheme within the fluorescent lamp ballast driver distinguishes between operating conditions during and after preheat of the lamp electrodes. By maintaining the voltage for powering the integrated circuit driver above its minimum threshold, the driver does not momentarily shut off during lamp turn on.
