  • Patent number: 7560867
    Abstract: A starter for a gas discharge light source is configured to measure an initial resistance of one or more filaments of the gas discharge light source, such as a fluorescent light, each time the gas discharge light source is initially powered via a ballast. The starter may initiate a preheat cycle to heat the one or more filaments. The duration of the preheat cycle may be automatically customized by the starter based on the initial resistance and a target hot resistance that is calculated by the starter based on the initial resistance. The duration of the preheat cycle may be automatically customized by the starter to optimize reliability and the life of the gas discharge light source.

  • Publication number: 20090120851
    Abstract: A water treatment system including a UV bulb, a moisture detector, and a control circuit responsive to the moisture detector to terminate power to the bulb when moisture is detected. The moisture detector includes a nonconductive substrate and a pair of conductors on the substrate. When moisture is not present, the detector is nonconductive. However, when moisture accumulates on the detector, the moisture provides a conductive path between the conductors so that the detector becomes conductive. When moisture is detected, the control circuit terminates power to the bulb and/or provides an appropriate indication to the system user.

  • Publication number: 20080170399
    Abstract: A lamp base for a dual-leg lamp is provided with at least one oversized leg mounting hole that permits relative movement of the lamp legs during temperature driven expansion and contraction. In one embodiment, only one leg of the lamp is glued to the lamp base. The absence of glue on one leg permits essentially free movement of the non-glued leg with respect to the base. In those embodiments that include only a single oversized leg mounting hole, the leg disposed within the oversized leg mounting hole is not glued so that the leg is free to move within the oversized hole. In those embodiments in which both leg mounting holes are oversized, it is acceptable for either (or both) of the legs to be non-glued.

  • Patent number: 7145342
    Abstract: A system for automated testing of the lamp filaments has an ohm meter. The ohm meter is used to determine the resistance of the lamp filament prior to energizing the lamp. A multiplexer switches the ohm meter from one lamp filament to the next so that the lamp filaments are quickly and accurately tested. After the cold resistance of the lamp filaments is measured, a power supply energizes the lamp filaments.
