The invention relates to the technical field of electric light sources, and particularly relates to a solar power supply dual-full-bridge injection locking power synthesis fluorescent lamp bank. Two RC oscillators are both connected with a resistor R3 and a capacitor C4 and oscillate synchronously; a self-oscillation chip 4, an output power transformer T1 of a full-bridge inverter A, a self-oscillation chip 6 and an output power transformer T2 of a full-bridge inverter B are fed into an adding coupler in opposite phases; the synthesized power is matched with the fluorescent lamp bank; reference crystal oscillator signals are injected into the RC oscillators of the two self-oscillation chips 4, 6 through a frequency divider so as to lock the phase; and large-power lighting is acquired, thereby avoiding too high temperature rise of devices, changes in the oscillation frequency, unbalance of the power and reduction of the lamplight; and lamp tube abnormal current detection signals are connected to SD ends of the oscillators of the two self-oscillation chips through a triode, thereby controlling quick stop of the oscillation to turn off a power metal oxide semiconductor (MOS) field effect transistor of the full-bridge inverter. The solar power supply dual-full-bridge injection locking power synthesis fluorescent lamp bank is applied to lighting in conference rooms, living rooms and houses.
