Abstract

The utility model relates to the electric light source illumination technical field and specifically discloses a solar power supply double-push injection-locking power synthesis neon lamp. Two self-sustained oscillation chips 4, 6 are together connected to a timing resistor R2 and a capacitor C4 for synchronous oscillation.

The synthesized power further undergoes a voltage boost and is then fed into a lamp tube circuit for turning a neon lamp tube on. 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. An excessive temperature rise of devices is prevented. Imbalanced oscillation frequency change power is also prevented. Light rays are further prevented from deteriorating. The neon lamp is suitably used in commercial decorative neon lamp advertisements powered by solar low-voltage heavy-current power supplies.
