Abstract: The present invention is directed to a lamp assembly for use in a point-of-use water treatment system or other device. The lamp assembly includes a condensing element to condense mercury in a bulb within the arc path of opposing filaments when the bulb is de-energized. In one embodiment, the time required for the lamp assembly to produce light upon subsequent re-energization of the bulb is significantly reduced because the mercury is in the intermediate portion of the bulb, within the filament arc path.

Abstract: A ballast circuit is disclosed for inductively providing power to a load. The ballast circuit includes an oscillator, a driver, a switching circuit, a resonant tank circuit and a current sensing circuit. The current sensing circuit provides a current feedback signal to the oscillator that is representative of the current in the resonant tank circuit. The current feedback signal drives the frequency of the ballast circuit causing the ballast circuit to seek resonance. The ballast circuit preferably includes a current limit circuit that is inductively coupled to the resonant tank circuit. The current limit circuit disables the ballast circuit when the current in the ballast circuit exceeds a predetermined threshold or falls outside a predetermined range.

Abstract: An ultraviolet light detector for detecting levels of ultraviolet light in a liquid disinfection unit comprises two solid state silicon photodetectors. A first photodetector generates a photo-induced current proportional to the amount of visible, infra-red, and ultraviolet light emitted. A second photodetector generates a photo-induced current proportional to the amount of visible and infrared light emitted. The photodetectors are electrically connected in reverse parallel, generation an output current equal to the difference between the photo-induced currents of the photodetectors. The output current is thus proportional to the UV light intensity. The output current may be converted into a voltage, which may be monitored to ensure that the ultraviolet light intensity is sufficient for complete disinfection of the liquid. An electronic control system may be provided so that the output voltage controls a solenoid valve and/or an alarm in the disinfection unit. In particular, the solenoid valve is configured to control the liquid flow through the disinfection unit, and the alarm may be activated to alert system attendants.

Abstract: A device for determining the level of UV-transmission through a flowing media This UV-transmission is determined by measuring and evaluating the radiation intensity of a UV-radiation source radiating through a zone of the medium. The emitting surface of the UV-radiation source partly extends into the flowing medium and partly into a reference space, or borders on the medium and the space. Two UV-sensors are directed at zones of equal irradiation intensity of the radiation source emitting surface. In this case, the one UV-sensor is arranged in the flowing medium and the other UV-sensor in the reference space. Both UV-sensors are connected to a measuring and evaluating circuit, which compares and evaluates the signals of the UV-sensors.

Abstract: A method for producing a gas discharge light source for emitting an electromagnetic radiation includes a gas discharge tube filled with at least one discharge gas material and having a device for generating a gas discharge includes the following method steps: igniting the gas discharge tube filled with the discharge gas material, performing a forming operation in which the electrical operating power of the gas discharge light source is at least as high as the desired continuous operation power, the gas discharge tube is held at a temperature which is at least as high as the subsequent operating temperature, the intensity of the emitted electromagnetic radiation in the region of the desired wavelengths is monitored and the partial pressure of the vaporized discharge gas material is varied until the intensity of the selected electromagnetic radiation has reached a maximum value, whereupon a reservoir with excess discharge gas material is separated from the gas discharge tube in such a manner that the gas discharge tube under operating conditions does not contain any condensed discharge gas material. A gas discharge tube having a discharge material forming a discharge gas under operating conditions is distinguished in that the discharge gas material is incorporated in the inner wall of the gas discharge tube and there is no longer any condensed discharge gas material in the gas discharge tube.
