Abstract: A circuit (300) for igniting a high intensity discharge (HID) lamp comprises input terminals (302,304), output terminal (306,308), a charging circuit (RIGN,CIGN), a transformer (320) having a primary winding (322) and a secondary winding (324), a MOSFET (340), and a clamping diode (DCLAMP). During operation, ignitor circuit (300) provides a high voltage (VIGN) for igniting an HID lamp. Ignitor circuit (300) provides an ignition voltage (VIGN) having a peak magnitude that is more predictable and less prone to degradation due to the influences of parasitic components. Additionally, ignitor circuit (300) may be realized in a manner that is significantly more cost-effective than comparable prior art circuits.

Abstract: The invention relates to an operating method for fluorescent lamps and a corresponding ballast, in which the brightness of the fluorescent lamps (LP) is set to the desired value by varying the switching frequency of the inverter switches (T1, T2). In order to prevent oscillations between different operating states in a critical dimming range, the power consumption of the fluorescent lamps (LP) is stabilized according to the invention by way of an additional control loop.

Abstract: A digitally compensated hysteretic power supply with enhanced resolution is provided. Such a power supply includes a comparator that is used to compare a load current sense signal with an internal signal generated from a digital-to-analog converter (DAC). A compensation circuit at a DAC input operates to improve current accuracy beyond the given DAC resolution. The current sense signal is converted to its digital equivalent, which is fed to a proportional-integral (PI) compensation loop, which in turn generates a relatively precise high resolution DAC input value. The DAC uses the higher part of the DAC value. The lower part of the DAC value is treated as a duty cycle number, and the DAC output is toggled between two levels at this duty cycle. This toggling generates a current output signal having a value that is the average of the two toggled values.

Abstract: Systems and method for detecting failure in solid state light sources and recovering from the failure are provided. A light engine including a controller circuit and strings of solid state light sources emits light in response to drive current provided by a driver circuit. The controller circuit monitors an output voltage of the driver circuit, and detects a failure of one of the solid state light sources. The failure is associated with a change in the output voltage of the driver circuit. The controller circuit then transmits a first signal to the driver circuit in response to detecting a failure, and the driver circuit is configured to decrease the drive current in response to the first signal.

Abstract: Systems and methods for detecting an incorrect load and preventing powering of that load, until a load change is detected, are disclosed. An incorrect load can be removed and a newly attached valid load can be operated without requiring a reset. A power supply or driver system for a lighting system including one or more solid state light sources includes the systems and methods. The power supply or driver system includes a processor and memory arrangement configured to detect whether a load is operable or non-operable while still being responsive to a new load being attached at any time, and to prevent the system from checking the same load more than once. These may be used in conjunction with features like auto-recovery, restart after faults, and load-hot-plug capability, while perhaps simultaneously reducing cyclical flashing of light output.

Abstract: A ballast including a driver circuit, a filament heating circuit, a current detector circuit, and a control circuit is provided. The driver circuit generates an oscillating current signal. The filament heating circuit heats filaments of a lamp connected to the ballast and includes a heating transformer with primary and secondary windings and a switching circuit. The primary winding is connected to the driver circuit and the switching circuit. The secondary winding is connected to the primary winding and may be connected to the lamp. The duty cycle of the switching circuit controls current provided from the driver circuit to the primary winding to heat the lamp. The current detector circuit is connected to the switching circuit and detects a parameter of the current in the primary winding, which indicates the number of lamp filaments connected to the ballast. The control circuit controls the driver circuit based on the detected parameter.
