Abstract: Disclosed are circuits and methods for driving discharge devices wherein during illumination, a first electrode is driven with pulses that maintain ON state wall charges, while a reference electrode is held at a constant voltage. With these circuits and methods, one or more reference electrodes are held to a reference voltage, such as ground, while one or more electrodes initiate two discharges necessary to maintain a wall charge. Additionally, the invention discloses driving methods that reduce electrode inductance while maintaining the separation of a driving side and a reference side. Embodiments divide the plurality of driving electrodes into two or more groups of electrodes and utilize a resonant driver to transfer charge between the groups of electrodes. The electrode inductance is dramatically reduced because adjacent electrodes, rows of electrodes or groups of rows, have substantially equal but opposite current flows.

Abstract: The present invention discloses a temperature control system for a backlight module, which applies to a backlight module with the light source quantity of the light-emitting module being increased to directly promote the brightness of LCD. The present invention can timely modulate the brightness of the light-emitting module to slow the temperature rising speed or gradually lower the temperature via the detection function of the thermistor and the PWM control of the control circuit. Thereby, the prevent invention can prevent from the malfunction of electronic elements or the decrease of service life caused by heat accumulation in the light-emitting module.

Abstract: The present invention discloses a halogen lamp, which comprises at least two burners, and a mains-toggle control means for controlling said at least two burners to operate alternatively, in order to achieve different illuminating effects, e.g. to achieve different illuminating angles or different illuminating brightness modes, etc.

Abstract: A rare gas illumination system and method are configured to provide a sweeping illumination effect. In one embodiment, the rare gas illumination system includes a tube containing a gas and having a first electrode at a first end and a second electrode at a second end. A first boot having a first transformer is coupled to the first end of the tube. A second boot having a second transformer is coupled to the second end of the tube. The system includes a controller having a microcontroller, a memory, and an output power driver. The memory is configured to store a plurality of control codes corresponding to a plurality of illumination patterns. The microcontroller controls the illumination pattern of the tube by executing the corresponding control code to selectively activate the output driver to provide a voltage signal to at least one of the first boot and the second boot.

Abstract: Emergency phone stations distributed at intervals of 1 or 2 km along a highway area and connected to a communications channel with a power line. Each phone station has a set of flash lamps which can be blinked in accordance with differing blinking schedules, and with a storage capacitor which stores flash energy. When a lamp is flashed, the storage capacitor discharges from the power line, the charging time-constant of each station being different due to differing distances from a central station. To impose an order on the network, central clocking is employed, with lamp ignitions occurring at each individual station being referenced to clocking signals common to all stations, so that the blinking schedules at all activated stations have a fixed phase interrelationship. This predetermines the times and sequences at which the storage capacitors will recharge. All storage capacitors are identical and are so selected that t.sub.0 /R.C.sub.ges =0.5 to 3, preferably 1.25, t.sub.
