Abstract
The utility model relates to the electric light source illumination technical field and specifically discloses a solar power supply double half-bridge injection-locking power synthesis high-voltage sodium lamp. RC oscillators of two self-sustained oscillation chips 4, 6 are together connected to a resistor R3 and a capacitor C5 for synchronous oscillation. A self-sustained oscillation chip 4 and half-bridge inverter A output power transformer T1, and a self-sustained oscillation chip 6 and half-bridge inverter B output power transformer T2 are fed into an addition coupler in a reverse-phase way for power synthesis and further sent to a lamp tube trigger circuit in a feedback way after a voltage boost. A high-voltage sodium lamp tube is then triggered to start. Signals of a reference crystal oscillator are injected into the 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 prevented. Light rays are further prevented from deteriorating. Sawtooth wave signals of a frequency modulation signal generator are accessed to the RC oscillators of the two self-sustained oscillation chips 4, 6 for suppressing light scintillation in a frequency modulation way. The solar power supply double half-bridge injection-locking power synthesis high-voltage sodium lamp is suitably used for solar power supply large-power high-voltage sodium lamp illumination.
