摘要： A ballast (20) for powering one or more gas discharge lamps comprises an Inverter (200) and a lamp fault protection circuit (400). Inverter (200) has an operating frequency that is load-dependent. Lamp fault protection circuit (400) monitors an electrical signal within inverter. In response to a change In the fundamental frequency of the electrical signal, such as what occurs when a lamp is removed, when a lamp approaches the end of Its operating life, or when an arcing condition occurs at one or more of the ballast output connections, lamp fault protection circuit (400) disables the inverter (200) for a predetermined shutdown period. Lamp fault protection circuit (400) also provides a restart function for periodically attempting to ignite and operate the lamps. Additionally, -in response to a sustained fault condition, lamp fault protection circuit (400) increases the predetermined shutdown period so as to minimize any undesirable effects due to the restart function.

摘要： A ballast (20) for powering one or more gas discharge lamps (70,72,74,76) comprises an inverter (200), an output circuit (300), and an arc protection circuit (400). Arc protection circuit (400) monitors an electrical signal within the output circuit (300). When an arcing condition occurs at the ballast output connections (302,304,306,308,310), the electrical signal includes a high frequency component having a fundamental frequency that is much greater than the normal operating frequency of the inverter (200). In response to the high frequency component exceeding a predetermined threshold, arc protection circuit (400) disables the inverter (200) for a predetermined shutdown period. Arc protection circuit (400) also provides a restart function for periodically attempting to ignite and operate the lamps. Arc protection circuit (400) is preferably realized using a microcontroller integrated circuit (440) with associated discrete circuitry, and is especially wellsuited for use in ballasts for powering multiple lamps.

摘要： A circuit (10) for powering a halogen lamp (20) comprises an inverter (100) and an output circuit (300). During operation, the inverter (100) and output circuit (300) provide a magnitude-limited current to the halogen lamp such that the lamp power during an initial period is substantially less than the lamp power during a steady-state operating period. Preferably, output circuit (300) is a non-isolated circuit that includes a current- limiting inductance, and inverter (100) includes a frequency control circuit (R2,C4,C7,Q3,R3,R5,C8) for operating the inverter at a higher frequency during the initial period so as to reduce stress upon the lamp filament and preserve the operating life of the lamp. The circuit (10) is especially suitable for powering low voltage halogen lamps.

摘要： A ballast (10) for powering at least one gas discharge lamp (70) having heatable filaments (72,74) includes an inverter (200), a resonant output circuit (400 ) coupled between inverter (200) and lamp (70), and a filament heating and ignition control circuit (600) coupled to inverter (200) and resonant output circuit (400) having a first resonant frequency and a second resonant frequency, wherein the first resonant frequency is substantially greater than the second resonant frequency. Filament heating and ignition control circuit (600) controls inverter (200) and resonant output circuit (400) during a preheat phase and during a normal operating phase. During the preheat phase, resonant output circuit (400) has an effective resonant capacitance corresponding to the first resonant frequency, and provides a first level of heating to the lamp filaments (72,74). During the normal operating phase, resonant output circui t (400) has an effective resonant capacitance corresponding to the second resonant frequenc y, and provides a second level of heating to the lamp filaments (72,74) that is negligible in comparison with the first level of heating. Control circuit (600) monitors a voltage within resonant output circuit (400) in order to compensate for any variation in the parameters of resonant output circuit (400) and to ensure that an appropriate level of preheating is provided to lamp filaments (72,74).

摘要： A ballast (10) for powering a lamp load (70) comprising one or more gas discharge lamps (72,74) includes an inverter (200), a resonant output circuit (400), and a control circuit (600). During operation of ballast (10), control circuit (600) monitors at least one voltage within one or more series resonant circuits of output circuit (400). When the monitored voltage reaches a specified level, control circuit (600) directs inverter (200) to maintain its operating frequency at a present value for a predetermined period of time, so as to allow output circuit (400) to provide a suitably high voltage for igniting the lamp(s). If the lamp(s) ignite within the predetermined period of time, control circuit (600) ceases controlling inverter (200) to maintain its operating frequency at the present value, so as to allow for normal operation of the lamp(s). Control circuit (600) also provides a lamp stabilization function, in which the inverter operating frequency is prevented from falling below a specified minimum value, and a protective function, in which inverter (200) is deactivated in response to failure of the lamp(s) to ignite within the predetermined period of time.
