Abstract

The invention relates to the technical field of electric light source lighting, in particular to a solar energy power source four-push-pull injection locking power synthesis neon lamp. Signals are fed into an adding coupler TB1 through a self-oscillation chip A and an output power transformer T1 of a push-pull inverter A' and through a self-oscillation chip B and an output power transformer T2 of a push-pull inverter B', signals are fed into an adding coupler TB2 through a self-oscillation chip C, an output power transformer T3 of a push-pull inverter C', a self-oscillation chip D and an output power transformer T4 of a push-pull inverter D', the signals of the adding coupler TB1 and the signals of the adding coupler TB2 are fed into an adding coupler TB3, power synthesis and pressure boost are conducted, the signals are fed into a lamp tube circuit so as to light a lamp tube starter, signals of a benchmark crystal oscillator are injected into the four self-oscillation chips through a frequency divider so as to enable phase positions to be locked and power to be stably output, and lamplight descending caused by excessive temperature rising, oscillation frequency changes and power imbalance of a device is avoided. Signals of a lamp tube abnormal current detector are connected with SD end protective power tubes of the four self-oscillation chips. The solar energy power source four-push-pull injection locking power synthesis neon lamp is suitable for commercial decorative lighting occasions with the solar energy light source high-power neon lamps.

[0002] Electronic ballasts in the prior art usually use LC or RC oscillators as the electric light source for neon lights. The oscillation frequency generated is affected by the poor stability of temperature changes and the power is not stable enough, resulting in a decrease in light intensity. Although the structure is simple and the cost is low

However, in order to obtain high-power lighting, the current of the device must be increased, especially for the low-voltage power supply of the solar power supply. The increase of the output power can only rely on the current to do work. Power amplitude imbalance with frequency

At the same time, when the large current passes through the coil, the temperature rises and the magnetic permeability decreases, and the magnetic saturation inductance becomes smaller and the impedance tends to zero. The working time of the lamp is proportional to the temperature rise, and the temperature rise accelerates the aging of the device. Burning out components shortens service life
