Abstract

The utility model relates to the technical field of electric light source lighting and specifically relates to a DC low-voltage push-push injection phase-locking power-synthesizing low-pressure sodium lamp. A self-oscillation chip 4 and a self-oscillation chip 6 are connected with a timing resistor R2 and a capacitor C4 for synchronous oscillation. Power synthesis of the self-oscillation chip 4 and an output power transformer T1 of a push-pull amplifier A and the self-oscillation chip 6 and an output power transformer T2 of the push-pull amplifier B are realized and the power is fed to a tube circuit for starting the DC low-voltage push-push injection phase-locking power-synthesizing low-pressure sodium lamp. Reference crystal oscillator signals are input to RC oscillators of the self-oscillation chip 4 and the self-oscillation chip 6 through a frequency divider for phase locking, so that luminance declination caused by power unbalance resulted from oscillation frequency changes since temperature rise of a device is too high is avoided. The DC low-voltage push-push injection phase-locking power-synthesizing low-pressure sodium lamp is suitable for low-pressure sodium lamp lighting occasions with DC low voltage and large current for power supply.
