Solar energy power source double-pushing injection locking power synthesis black light lamp

Abstract

The invention relates to the technical field of electric light source lighting, in particular to a solar energy power source double-pushing injection locking power synthesis black light lamp. Two self-oscillation chips (4 and 6) are jointly connected with a timing resistor R2 and a timing capacitor C4 to generate synchronous oscillation, namely, one is the self-oscillation chip 4 and the output power transformer T1 of a push-pull inverter A, and the other is the self-oscillation chip 6 and the output power transformer T2 of a push-pull inverter B; signals are fed into an adding coupler; power synthesis and boost are conducted; the signals are fed into a lamp tube circuit black light lamp so as to conduct ultraviolet radiation. Signals of a benchmark crystal oscillator are injected into RC oscillators of the two self-oscillation chips (4 and 6) through a frequency divider to enable phase positions to be locked, light source descending caused by excessive temperature rising, oscillation frequency changes and power imbalance of a device is avoided, and the service life is prolonged. The solar energy power source double-pushing injection locking power synthesis black light lamp is suitable for occasions such as a village with an inconvenient alternating current power source, fields and gardens powered by solar energy power sources with the low voltage and the large current, for trapping and killing injurious insects.

[0002] In the prior art, LC or RC oscillators are often used as the light source for black light lamps. The resulting oscillation frequency is affected by poor stability of temperature changes, and the power is unstable and the light intensity decreases. Especially, black light lamps powered by solar power supply work at low voltage and high current. low cost

Due to the low power supply voltage, it is necessary to increase the device current to obtain high-power lighting, resulting in a sharp increase in the power consumption of the oscillating power tube and an excessively high temperature rise, 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
