    Abstract: The IRS21681 D (Figure 2) is a fully integrated, fully protected 600V ballast control IC designed to drive all types of fluorescent lamps. The IRS21681D (Figure 2) is based on the popular IR2166 control IC with additional improvements to increase ballast performance. PFC circuitry (Figure 19) operates in critical conduction mode and provides high PF, low THD and DC bus regulation. The IRS21681D (Figure 2) features include programmable preheat and run frequencies, programmable preheat time, programmable ignition ramp, programmable PFC over-current protection, and programmable end-of-life protection. Comprehensive protection features such as protection from failure of a lamp to strike, filament failures, end-of-life protection, DC bus under-voltage reset as well as an automatic restart function, have been included in the design. The IRS2168D (Figure 2) has, in addition, closed-loop half-bridge ignition current regulation and a novel fault counter. The IRS21681D, unlike the IRS2168D, ramps up during ignition and shuts down at the first over- current fault. The IRS21681D and IRS2168D are both available in either 16- pin PDfP or 16-pin narrow body SOIC packages.

    Abstract: A circuit for dimmably driving fluorescent lamps (102, 104, 106) from a DC supply voltage includes: input nodes (174, 176) having input capacitors (184, 186) connected therebetween; a half-bridge transistor inverter (178, 180) connected between the input terminals; a series-resonant LC oscillator (196, 198) coupled in series between the half-bridge transistors and the input capacitors; an output transformer (212) having a primary winding (214) connected in series with the LC inductor (196) and in parallel with the LC capacitor (198) and a secondary winding (216) for connection to the lamp load; and first and second voltage clamp diodes (215A, 215B) connected between an intermediate point on the primary winding and the input nodes respectively. The voltage clamp diodes, in conjunction with the input capacitors, provide significant enhancement in reduction of power transferred to the lamps when the DC supply voltage is reduced, allowing lamp dimming to be simply and efficiently effected by reduction of the DC supply voltage.

    Abstract: By using a ceramic chip capacitor, it is possible to reduce the size of a discharge lamp operation device of a bulb-shaped fluorescent lamp. Even when the ceramic chip capacitor is short-circuited, it is possible to suppress excessive temperature increase. The ceramic chip capacitor is a capacitor (C5) for preheating and start contributing to the resonance of the discharge lamp device connected in parallel to a light emitting tube (4). The capacitor (C5) is located between wrapping pins (61, 61) and mounted on the surface of a substrate (58). An inverter circuit limits the current supplied to the ceramic chip capacitor to the normal current multiplied by 1.5 or below even when the capacitor (C5) is short-circuited, thereby preventing excessive temperature increase of the capacitor (C5).

    Abstract: Methods and apparatus for powering a ballast that is dimmable and has a high power factor. The ballast circuit includes a rectifier, bypass capacitor, a driver circuit, and a resonant circuit that are configured to actuate a light source, such as a fluorescent lamp. Specifically, the bypass capacitor stores energy to produce a high frequency current which is introduced into the resonant circuit to continually recycle energy in the resonant circuit, resulting in a circuit with a high power factor. Further, because the current flowing into the resonant circuit is substantially sinusoidal, the circuit generally has an ideal crest factor, thereby increasing the lifespan of the light source.
