Abstract

The utility model relates to the electric light source illumination technical field and specifically discloses a direct-current low-voltage power supply four-push-pull injection-locking power synthesis metal halide lamp. A self-sustained oscillation chip A push-pull inverter A' output power transformer T1 and a self-sustained oscillation chip B push-pull inverter B' output power transformer T2 are fed into an addition coupler TB1. A self-sustained oscillation chip C push-pull inverter C' output power transformer T3 and a self-sustained oscillation chip D push-pull inverter D' output power transformer T4 are fed into an addition coupler TB2. The addition coupler TB1 and the addition coupler TB2 are fed into an addition coupler TB3 for power synthesis. The synthesized power further undergoes a voltage boost and is then fed into a lamp tube trigger circuit for turning a lamp tube on. Signals of a reference crystal oscillator are injected into four self-sustained oscillation chips through a frequency divider for phase locking and output power stabilizing. An excessive temperature rise of devices is prevented. Imbalanced oscillation frequency change power is also prevented. Light rays are further prevented from deteriorating. Triangular-wave signals of a frequency modulation signal generator are accessed to the four self-sustained oscillation chips for suppressing light scintillation in a frequency modulation way. Signals of a lamp tube abnormal current detector are accessed to SD ends of the four self-sustained oscillation chips for power tube protection. The metal halide lamp is suitably used in large-power metal halide lamp illumination occasions where a direct-current low-voltage power source is supplied.
