Abstract

The invention relates to the technical field of electric light sources, in particular to a solar energy power source double-pushing injection locking LED array lamp. Two self-oscillation chips (4 and 6) are jointly connected with a timing resistor element R2 and a timing capacitor element C3 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 in an anti-phase mode; power synthesis is conducted; the signals are fed to the LED array lamp in a full-wave rectification mode. 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, lamplight descending caused by excessive temperature rising, oscillation frequency changes and power imbalance of a device is avoided, and the service life of the LED array lamp is prolonged. The solar energy power source double-pushing injection locking LED array lamp is suitable for lighting occasions powered by solar energy power sources with the low voltage and the large current.

Description

technical field [0001] The invention relates to the technical field of electric light source lighting, in particular to a solar power source double injection lock light-emitting diode LED array lamp. Background technique [0002] In the prior art, electronic transformers generally use LC or RC oscillators as the light source of light-emitting diode LED array lamps. The oscillation frequency generated is poorly stabilized by temperature changes, which affects power instability and decreases in light intensity. Especially solar-powered light-emitting diode LED array lights work in Low voltage, high current, although the electronic transformer for DC-AC-DC inverter is simple in structure and low in 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 oscilla...
