Abstract

The utility model relates to the electric light source illumination technical field and specifically discloses a solar power supply double-full-bridge injection-locking power synthesis halogen lamp group. Two RC oscillators are together connected to a resistor R3 and a capacitor C4 for synchronous oscillation. A self-sustained oscillation chip 4 and full-bridge inverter A output power transformer T1, and a self-sustained oscillation chip 6 and full-bridge inverter B output power transformer T2 are fed into an addition coupler in a reverse-phase way for power synthesis. The synthesized power matches a halogen lamp tube group. Signals of a reference crystal oscillator are injected into RC oscillators of the two self-sustained oscillation chips 4, 6 through a frequency divider for phase locking. 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. Signals of a lamp tube abnormal current detector are accessed to SD ends of oscillators of the two self-sustained oscillation chips through a triode. Oscillation is rapidly controlled to stop. Full-bridge inverter power MOS tubes are further turned off. The halogen lamp group is suitably used for commercial decorative large-power halogen lamp illumination.
