摘要： The invention describes a method of driving a gas-discharge lamp (1) according to conditions in a specific region (R) of the lamp (1), which gas-discharge lamp (1) comprises a burner (2) in which a first electrode (4) and a second electrode (5) are arranged on either side of a discharge gap, which lamp (1) is realised such that the position (PCs) of a coldest spot during an AC mode of operation is in the vicinity of the first electrode (4), which method comprises the steps of initially driving the lamp (1) in the AC mode of operation; monitoring an environment variable of the lamp (1), which environment variable is indicative of conditions in a specific region (R) of the lamp (1); switching to a temporary DC mode of operation at a DC power value on the basis of the monitored environment variable, whereby the first electrode (4) is allocated as the anode; and driving the lamp (1) in the DC mode of operation until the monitored environment variable has returned to an intermediate environment variable threshold value (T
DCAC ). The invention also describes a gas-discharge lamp and a driver for a gas-discharge lamp.

摘要： A continuous mode electronic ballast operates a lamp. A buck converter is configured to generate a direct current (DC) bus voltage at buck converter output. An inverter circuit is operationally coupled to the buck converter output, and configured to receive the DC voltage and convert the DC voltage into an AC voltage to drive the lamp. A short circuit protection circuit is operationally coupled to the buck converter output to sense the DC bus voltage, compare the sensed DC voltage to a predetermined threshold and, based on the comparison, shut down the inverter circuit.

摘要： A level shift IC (3b) of a power supply/shutoff section (3) is operable, when a shutoff signal (Sa) is input from a timer circuit (8) for a time T during an ON state of a discharge lamp (7), to turn off a MOSFET (3a) so as to shut off power supply to a smoothing capacitor (4). When a detection signal (Sb) of a capacitor voltage is lowered to a value less than a reference voltage Vr1 during input of the shutoff signal (Sa), an output of a comparator (10) is changed from an H level to an L level in an inverted manner. In conjunction with this change, respective outputs of an auxiliary control circuit (12) and a NOT element (12a, 12b) are changed from an L level to an H level in an inverted manner. As a result, a current flows from the NOT element (12a) to an LED (13b) through a resistor (13a) to turn on the LED (13b). Thus, a life end of the smoothing capacitor 4 is annunciated, and a main control circuit (6) is operable to suppress an output of an inverter main circuit (5).

摘要： During stationary operation a circuit arrangement for operating a high-pressure discharge lamp supplies a direct current to the lamp which is commutated at a low frequency. During take-over, between ignition and stationary operation, a high frequency current is supplied to the lamp after each commutation during a time interval that is shorter than half a cycle of the commutation. By supplying the lamp in this way, it forms a smaller load during take-over, so that the requirements that the circuit arrangement has to meet are less severe.
