Abstract

The invention relates to the technical field of electric light source illumination and specifically discloses a solar power supply double-push injection-locking power synthesis halogen tungsten lamp. Two self-sustained oscillation chips 4, 6 are together connected to a timing resistor R2 and a capacitor C4 for synchronous oscillation. A self-sustained oscillation chip 4, an output power transformer T1 of a push-pull inverter A, a self-sustained oscillation chip 6, and an output power transformer T2 of a push-pull inverter B are fed into an addition coupler for power synthesis. The synthesized power is fed into a lamp tube circuit for turning a halogen tungsten lamp tube on. Signals of a reference crystal oscillator are injected into RC oscillators of the two self-sustained oscillation chips 4, 6 through a frequency divider for phase locking. Excessive temperature rise of the device, changes of oscillation frequency, imbalanced power and dim light are avoided. The halogen tungsten lamp is suitably used in illumination occasions as a halogen tungsten lamp powered by a solar low-voltage heavy-current power supply.

Description

technical field [0001] The invention relates to the technical field of electric light source lighting, in particular to a tungsten-halogen lamp with dual push-injection lock power synthesis of solar power. Background technique [0002] In the prior art, LC or RC oscillators are commonly used as the light source of tungsten-halogen lamps. The oscillation frequency generated is affected by the poor stability of temperature changes, and the power is unstable and the light intensity drops. The DC-AC inverter electronic transformer has simple structure and 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 cu...
