摘要： A power supply for high voltage, low current gas discharge tubes such as neon, argon, and mercury vapor. A free running, flyback oscillator, converts D.C. voltage energy into radio frequency energy by means of a compact, ferrite transformer and associated circuitry. The primary winding is tuned by a resonant capacitor and driven by a power transistor. A high voltage, centertapped winding of a ferrite transformer drives the gas tube load directly. A feedback winding arranged across the transistor base and emitter junction sustains oscillation and controls the drive level of the transistor by means of a regulating circuit which controls the amplitude of the current. Oscillator starting is achieved by means of an on-off switch which supplies a single starting pulse to the power transistor or by means of a time delayed starting pulse. A MOSFET transistor connected to the power transistor base and a current sensing transformer arranged in series with the primary winding, disables the power transistor momentarily at the end of a conducting cycle. Charge carries are depleted in the base-cathode region, resulting in resetting the transistor quickly such that it can withstand a forward voltage of 700 volts in the off state.

摘要： In microwave energized ultraviolet bulbs, much of the input energy is converted to heat emissions. It has been found that the efficiency of such a bulb can be optimized by monitoring power density of different portions of the UV spectrum (for example, UVA and UVC) and adjusting input power to the bulb and/or the bulbs temperature accordingly. This may be used not only to improve efficiency of the bulb but also to improve the efficiency of emissions at either UVA or UVC. A control system and suitable control parameters are described.

摘要： A system and method of automatic cycling control for HID lamps, comprising a switching device for switching power to the HID lamp, a first timer operatively connected to the power switching device, and a second timer operatively connected to the power switching device, wherein the first timer starts timing when the power switching device powers the HID lamp and signals the power switching device to extinguish the HID lamp when the first timer counts to an operating time setpoint, and the second timer starts timing when the power switching device extinguishes the HID lamp and signals the power switching device to power the HID lamp when the second timer counts to a cooling time setpoint. If the lamp is turned off and on before the operating time setpoint is met, the system will reset and begin a new operating timing period.
