    摘要: There is provided an LED lighting device having a satisfactory temperature characteristic and a small amount of variation in output current. The step-down chopper is provided with a first circuit including the switching element, the impedance means and a first inductor connected in series and a second circuit including the first inductor and a diode connected in series. A self-excited drive signal generation circuit is provided with a second inductor magnetically coupled with the first inductor and applies a voltage induced in the second inductor to the switching element to keep the switching element on. A turn-off circuit outputs an output voltage when the voltage of the impedance means detected by a comparator exceeds the reference value, and the output voltage allows a switching element to turn on to short-circuit the output terminals of the self-excited drive signal generation circuit, resulting in that the switching element is turned off.

    摘要: A power supply apparatus includes a direct current power source having a pair of terminals. First and second switching elements are connected in series between the pair of terminals of the direct current power. A load circuit, which includes a resonance inductance and a resonance capacitance, receives a high-frequency alternating current generated by a switching of the first and second switching elements. An unsaturated transformer has a first winding connected to the load circuit, and a second winding generating an induced voltage in proportion to a current flowing in the load circuit. A drive resonance circuit includes a capacitance, and an inductance of the second winding. The drive resonance circuit produces a resonance output to cause the first and second switching elements to alternately conduct. The power supply may be used in a ballast for a discharge lamp.

    摘要: A self ballasted fluorescent lamp includes a rectifier which full wave rectifies AC power from a commercial source. A smoothing capacitor smoothes the rectified power. The smoothed, rectified power is provided to a high frequency generating circuit which drives the fluorescent lamp. The capacitance value C of the smoothing capacitor is selected such that W.gtoreq..alpha.C, where W (in watts)is the rated service power of the fluorescent lamp, and .alpha. is related to a ratio of W to C0 (in .mu.F). C0 is a capacitance value of the smoothing capacitor for which the 5th harmonic component of the input current is 61% of the fundamental component of the input current when the fluorescent lamp operates under fixed conditions. When the above condition is met, the percentage of harmonic content falls within IEC standards, etc.

    摘要: An electrolytic capacitor and a ballast choke of a lighting circuit, are disposed on a first face of a circuit board facing a base, and a one-package switch of the lighting circuit is disposed on a second face, facing a fluorescent lamp. The one-package switch comprises field effect transistors contained in a single package and serve as two inverter switches for driving the fluorescent lamp. The one-package switch is a generally rectangular SMD with dimensions of not more than 6 mm respectively in length and width and mounted on the second face of the circuit board by means of terminals of the one-package switch. The one-package switch enhances heat dissipation properties of the circuit, enables the reduction of its dimensions, and increases the mounting efficiency.
