Abstract

The invention relates to the technical field of electric light source lighting, in particular to a solar energy power source double half-bridge injection locked power synthesis black light lamp. The lamp comprises a solar power source, a black light lamp tube, a standard crystal oscillator, a frequency divider, a self-oscillation chip 4, a self-oscillation chip 6, a half-bridge inverter A, a half-bridge inverter B and a phase adding coupler. Two RC oscillators are jointly connected with a resistor R3 and a capacitor C5 to generate synchronous oscillation, namely, one is an output power transformer T1 of the self-oscillation chip 4 and the half-bridge inverter A, and the other is an output power transformer T2 of the self-oscillation chip 6 and the half-bridge inverter B; power synthesis and boost are conducted through the phase adding coupler; the signals are connected to the lamp tube, and the lamp tube is started. Signals of the standard crystal oscillator are injected into the RC oscillators of the self-oscillation chip 4 and the self-oscillation chip 6 through the frequency divider, then phase positions are locked, so that the phenomena that temperature of components is too high, oscillation frequency changes, power is unbalanced, and light dims are avoided. The solar energy power source double half-bridge injection locked power synthesis black light lamp is suitable for a farmland and an orchard to induce and kill pests.

[0002] In the prior art, LC or RC oscillators are usually used as the electric light source for black light lamps. 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

In order to obtain high-power lighting, the current of the device must be increased, and the power consumption of the oscillating power tube will increase sharply and the temperature will rise too high, resulting in a change in the oscillation frequency. As a result, the power amplitude of the light will be unbalanced as the frequency changes.

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
