摘要： A combination-type high frequency inverter connects an isolation leakage transformer, a smoothing condenser, a resonance condenser, a first field-effect transistor and a second field-effect transistor to a diode bridge and rectifies the voltage of an AC power source in a non-smoothing rectification manner. A load circuit has a secondary winding of an isolation leakage transformer, a fluorescent lamp and a condenser. The ‘on’ duration of the first field-effect transistor is variable. The duration of on-duty of the second field-effect transistor is fixed. Adjusting charge voltage on the smoothing condenser changes the high frequency output voltage and the load characteristics. Load characteristics, optimal for the current mode, are given to the fluorescent lamp, in accordance with whether the flourescent lamp is in either start-up or luminance mode. Since the ‘on’ duration of the first-field effect transistor is variable, output compensation for fluxuation in source voltage is easily conducted.

摘要： The electrodes of a discharge lamp are prevented from reaching damaging temperatures which tend to occur when the discharge lamp is near the end of its useful life. The combination of a discharge lamp and luminaire contribute to ensuring the discharge lamp remains unilluminated when nearing the end of its useful life to prevent high temperature damage. Load circuit characteristics are set to provide low release voltage and high short-circuit current during full-intensity illumination, and high release voltage and low short-circuit current during dimmed operation. The discharge lamp operating in a dimmed mode at the end of its useful life is switched to full-intensity illumination mode to ensure the discharge lamp becomes unilluminated. This configuration prevents high temperatures at the electrodes from damaging the glass bulb, base, socket and other components of the discharge lamp and luminaire.
