Abstract

The invention relates to the technical field of electric light sources and specifically discloses a solar power supply four-full-bridge injection-locking power synthesis electrodeless lamp group. A self-oscillation chip A, an output power transformer T1 of a full-bridge inverter A', a self-oscillation chip B, and an output power transformer T2 of a full-bridge inverter B' are fed into an addition coupler TB1. A self-oscillation chip C, an output power transformer T3 of a full-bridge inverter C', a self-oscillation chip D, and an output power transformer T4 of a full-bridge inverter D' 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 is fed into a lamp tube circuit for turning a lamp tube group on in a matching way. Signals of a reference crystal oscillator are injected into the four self-oscillation chips through a frequency divider for phase locking and output power stabilizing. Excessive temperature rise of the device, changes of oscillation frequency, imbalanced power and dim light are avoided. Signals of a lamp tube abnormal current detector are accessed to the SD ends of the four self-oscillation chips for power tube protection. The electrodeless lamp group is suitably used in meeting rooms, living rooms and households for illumination.

Description

technical field [0001] The invention relates to the technical field of electric light source lighting, in particular to a solar power four-full-bridge injection lock power synthesis electrodeless lamp group. Background technique [0002] In the prior art, an LC or RC oscillator is usually used as the electric light source of the electrodeless lamp group. 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, so that the power consumption of the oscillating power tube will increase sharply and the temperature will rise too high. 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 t...
