摘要： A fluorescent lamp operating circuit includes a high frequency electronic ballast circuit for providing a controlled output to a fluorescent lamp load. A control signal is detected from the power line carrier which includes binary data indicative of the illumination level desired. The control signal comprises a multi-bit binary signal which is detected by the control circuit and used to control the frequency of the power supply circuit so that the fluorescent light illumination level may be dimmed over a wide range.

摘要： An electronic ballast for a gas discharge lamp including an inverter (18) the output frequency of which is controlled by a switching transformer (T2, T3) which is coupled to a transformer winding (T4) that senses current through a load (20, L1) whereby the frequency varies to maintain a substantially constant current through the load. The circuit thus adapts itself to a number of lamps which may be of different types. A «slow-start» circuit (16) is provided which allows limited current via resistor (R1) during starting of the lamp, in the event of circuit failure and when a lamp is not present and has a by-pass circuit (24) activated via transformer windings (T1, T4) to switch on only in response to striking of the lamp.

摘要： Für die Speisung von Niederdruckgasentladungslampen geeignetes Vorschaltgerät wird mit Gleichspannung (U = ) gespeist und gibt eine Wechselspannung mit konstanter Amplitude und variabler Frequenz ab. Es enthält einen Wechselrichter aus zwei in Serie geschalteten rückwärtsleitenden Thyristoren (Th1, Th2) und einen Zündimpulserzeuger. An den Ausgangsklemmen (A, B) des Wechselrichters werden über einen Kondensator (3) und eine erste Drossel (4) die Niederdruckgasentladungslampen (2) angeschaltet. Parallel zu jeder Niederdruckgasentladungslampe (2) liegt eine zweite Drossel (6). Die Werte des Kondensators (3), der beiden Drosseln (4,6), die Höhe der Gleichspannung (U = ) und die Frequenz des Wechselrichters sind so aufeinander abgestimmt, daß vor dem Zünden der Gasentladung bei niedriger Frequenz etwa der vorgeschriebene Heizstrom (I H ) fließt und daß nach dem Zünden der Gasentladung bei steigender Frequenz bis zum Erreichen von etwa 40 % des Lichtstroms sich der Heizstrom (I H ) nur unwesentlich und bei weiter steigender Frequenz bis zum Erreichen des Nennlichtstroms auf weniger als 25 % seines Anfangswertes verringert.

摘要： The invention relates to a lamp for producing illuminating radiation, said lamp comprising an electronic ballast 102 for establishing an ignition voltage for the lamp in order to initiate the production of illuminating radiation, said electronic ballast 102 comprising at least two switching transistors Q1, Q2 for supplying current to at least one coil L1 which develops the lamp ignition voltage, and the electronic ballast 102 having a control circuit 104 integrated therewith. The electronic ballast 102 comprises at least two resistors R8 and R10 arranged at least in a series connection relative to each other for measuring and/or regulating the currents of said at least two switching transistors Q1 and Q2, said resistor R8 being in connection with the switching transistor Q2 and the resistor R10 being in a series connection with the resistor R8 and with a voltage source. The electronic ballast 102 comprises the series connection of said resistors R8 and R10 for operating said control circuit 104 in order to detect whether a current passing through the switching transistor Q1 or Q2 is overly high with respect to a limit current value set for the control circuit, and by operating said control circuit 104, for immediately switching off the control of that switching transistor Q1 or Q2 which switching transistor Q1 or Q2 has been found with an overly high passing current and for immediately switching on the current of the other switching transistor Q1 or Q2.

摘要： An inverter controller selectively drives inverter switching elements with a preheat frequency (f1), a start frequency (f2), and an ON frequency (f3) which are different from one another, so as to obtain a preheat mode, a start mode, and an ON mode. There are provided reset means for performing start mode operation when voltage supplied to the inverter is lowered than a first threshold value, and inverter stop means for stopping the inverter when an error of the electric discharge lamp is detected. A timer provided for generating a signal to decide start of the preheat mode, the start mode, or the ON mode generates a reset signal inhibit signal for inhibiting operation of the reset means and an inverter stop inhibit signal for inhibiting operation of the inverter stop means. An inverter controller has frequency sweep means for gradually changing the switching frequency from the start frequency to the ON frequency. The timer inhibits operation of the reset means only during a period from the moment when the preheat frequency is selected to the moment when the switching frequency becomes ON frequency. The timer inhibits operation of the inverter stop means only during a period from the moment when the preheat frequency is selected to the moment when the switching frequency begins to change from the start frequency to the ON frequency.
