    摘要: A rapid-start fluorescent lamp system includes a ballast circuit, rapid-start fluorescent lamps and power reducing means for controlling the application of energy to the lamps. The power-reducing means controls the energy to N/O switches from the energy source upon ionization of the rapid-start fluorescent lamps.

    摘要: A circuit for starting and operating a low-voltage fluorescent lamp from a 120 volt AC supply. The circuit includes a choke type ballast connected in series with the lamp and inductively coupled to a pulse train generator comprising an RC energy storage circuit connected across the line and a voltage sensitive transistorized relaxation oscillator having a divider network for sensing lamp voltage. In a preferred embodiment the circuit is employed in a preheat mode of operation in combination with an electronic starter circuit comprising a PTC resistor, silicon diode and SCR series connected across the lamp.

    摘要: A tri-model circuit breaker for use in a rapid-start fluorescent lamp. The circuit breaker includes a glass bulb, first and second electrical leads sealed into and passing through the glass bulb, and a bimetallic element disposed within the bulb and having first and second end portions. The first end portion of the bimetallic element is affixed to the first electrical lead while the second end portion of the bimetallic element is formed to be spaced from the second electrical lead at a first elevated temperature and in contact with the second electrical lead at ambient temperature and at a second elevated temperature higher than the first elevated temperature. The contact points of the circuit breaker at ambient and at the second elevated temperature are at the same location within the breaker.
