Abstract: An apparatus for driving a discharge lamp includes a piezoelectric transformer connected to the discharge lamp. A drive device operates for feeding controllable power to the discharge lamp via the piezoelectric transformer to controllably drive the discharge lamp. A lighting control device operates for controlling the drive device to light the discharge lamp.

Abstract: A power saving dimming apparatus for gas discharge lamps activates a system of gas discharge lamps through a phototransistor network sensitive to the infrared spectrum rather than the normal visible spectrum. The phototransistor network allows power to be supplied to the apparatus, resulting in the turning on of the lamps whenever daylight conditions exist which are insufficient to produce infrared light. When power is applied to the apparatus, either at initial turn on or after a momentary interruption, the apparatus applies full power to the primaries of the lamp ballasts for a preselected time period, thus ensuring all the lamps in the system light. After the preselected time period has passed, the apparatus automatically dims the lamps and maintains them in the dimmed state.

Abstract: A method and a ballast for starting a discharge lamp capable of making a rapid start while restraining the overshoot of the light output. The ballast can separately give the initial start time period of applying a maximum power rating to the lamp and the subsequent curve along which the power decreases to a normal power rating of the lamp. A power is varied along a particular run-up curve so as to apply the maximum power rating and subsequently apply the power decreasing to the normal power rating. The run-up curve is derived from a reference curve having a power level decreasing with time. The reference curve has a maximum value above the maximum power rating, and has an inflection point near the maximum power rating to define first and second reference curves above and below the inflection point, respectively. The first reference curve has a first average slope for a first time period from a point of the maximum value to the inflection point. The second reference curve has a second average slope for a second time period which starts from the inflection point and has the same length as the first time period. The second average slope is greater than the first average slope. The run-up curve is a continuous composite curve of the maximum power rating defined by a portion thereof below the reference curve and the remainder of the reference curve defined between the maximum power rating and the normal power rating.

Abstract: A direct voltage source (1) delivers a voltage (U.sub.B) at its output terminals, which is then converted by a direct voltage/direct voltage converter (2) to a higher value. This higher voltage value (U.sub.D) constitutes the input voltage for a controlled full bridge circuit (3), which generates a controlled alternating current (I.sub.L) or an alternating voltage (U.sub.L) from the supplied input voltage. This alternating voltage is present at the output terminals (4, 5) and constitutes the supply voltage for a high-pressure gas discharge lamp. A control circuit (7), which supplies its control pulses via a line (8) is provided to control the full bridge circuit. In addition, an ignition circuit (9) is provided, which supplies the ignition voltage via the line (10) to the high-pressure gas discharge lamp (6). In accordance with the invention, the full bridge circuit (3) is controlled by the control circuit (7) in such a way that the duration of the half-wave phases of the lamp voltage (U.sub.L) or the lamp current (I.sub.L) is variable. In this case, the variability is selected in dependence on the respective temperature of the electrodes (11, 12) of the high-pressure gas discharge lamp.

Abstract: In a discharge bulb control, a time constant circuit comprised of a capacitor and a resistor is used to determine an electric power to be supplied to a discharge bulb. During a warm-up period of the discharge bulb, the capacitor is charged to produce a voltage which varies, toward a predetermined voltage, with an electric current flowing thereto so that the electric power is increased gradually. After the warm-up control, the time constant for charging the capacitor is reduced to maintain the capacitor voltage at the predetermined voltage. Even with the current leakage occurring in the capacitor after the warm-up control, the electric power is controlled by the predetermined voltage which is not influenced by the current leakage. Thus, the electric power applied to the discharge bulb after the warm-up control can advantageously be maintained at the required level.

Abstract: The present invention relates to an inverter driven lamp arrangement. The arrangement provides for the sensing of both lamp voltage and current. The arrangement also provides for a large current during times of low voltage and a small current during times of high voltage. The sensing of lamp current is done by a current detector that is connected to a resonance circuit whose output is applied in signal form to a lamp start control circuit. The resonant circuit is a series connected resonant circuit composed of a choke coil and a first capacitor. This series connected arrangement is further connected in series with a second non-resonant capacitor. Also the arrangement includes circuitry to gradually reduce the frequency of the inverter just after the lamp starts.
