Abstract

The utility model relates to the electric light source illumination technical field and specifically discloses a solar power supply injection-locking power synthesis light-modulation fluorescent lamp. The fluorescent lamp comprises a fluorescent tube, a solar power supply, a reference crystal oscillator, a phase light-modulation chip, a push-pull amplifier, a push-pull oscillator and a power synthesis coupler. The output of a voltage controlled oscillator VCO of the phase light-modulation chip is connected with the push-pull amplifier. An output power transformer T1 and a push-pull oscillator output power transformer T3 are fed into the addition coupler for power synthesis. The synthesized power further undergoes a voltage boost and then makes the fluorescent tube turned on in a matching way. Signals of the reference crystal oscillator are injected into the voltage controlled oscillator VCO through a frequency divider for phase locking. After a power synthesis of the push-pull amplifier transformer T1 and a push-pull oscillator transformer T3, a cross-coupling injection-locking frequency pulls a push-pull oscillator coherent synchronous locking phase. Large-power illumination is achieved. An excessive temperature rise of devices is prevented. Imbalanced oscillation frequency change power is also prevented. Light rays are further prevented from deteriorating. The fluorescent lamp is suitably used in illumination occasions as a light-modulation fluorescent lamp powered by a solar low-voltage heavy-current power supply.
