Abstract

The invention relates to the technical field of electric light source lighting, and particularly relates to a solar power supply dual-half-bridge injection locking power synthesis high pressure sodium lamp. RC oscillators of two self-oscillation chips 4, 6 are both connected to a resistor R3 and a capacitor C5 and oscillate synchronously, the self-oscillation chip 4, an output power transformer T1 of a half-bridge inverter A, the self-oscillation chip 6 and an output power transformer T2 of a half-bridge inverter B are fed into an adding coupler in opposite phases, and synthesized power and booster voltage are fed into a lamp tube triggering circuit to trigger the high pressure sodium lamp, thereby turning on the high pressure sodium lamp. Reference crystal oscillator signals are injected into the RC oscillators of the two self-oscillation chips 4, 6 through a frequency divider to lock the phase, and large-power lighting is acquired, thereby avoiding too high temperature rise of devices, changes in oscillation frequency, unbalance of the power and reduction of the lamplight. Sawtooth signals of a frequency-modulated signal generator are connected to the RC oscillators of the two self-oscillation chips 4, 6 to modulate the frequency and suppress flickering of the lamplight. The high pressure sodium lamp provided by the invention is applied to solar power supply large-power high pressure sodium lamp lighting occasions.

Description

technical field [0001] The invention relates to the technical field of electric light source lighting, in particular to a solar power source double half-bridge injection lock power synthesis high pressure sodium lamp. Background technique [0002] In the prior art, electronic ballasts generally use LC or RC oscillators as the high-pressure sodium lamp light source, and 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, which will cause the power consumption of the oscillating power tube to 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 ...
