Problems solved by technology

[0002] Electronic ballasts in the prior art usually use LC or RC oscillators as power-synthesized neon light sources, and the oscillation frequency generated is affected by poor temperature stability 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 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 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

Abstract

The invention relates to the technical field of electric light source lighting, and particularly relates to a dual-full-bridge injection phase-locking power synthesis neon lamp. Two RC oscillators are both connected to a resistor R11 and a capacitor C14 and oscillate synchronously; a self-oscillation chip 4, an output power transformer T1 of a full-bridge inverter A, a self-oscillation chip 6 and an output power transformer T2 of a full-bridge inverter B are fed into an adding coupler in opposite phases; synthesized power, booster voltage and rectified current are fed into a lamp tube; reference crystal oscillator signals are injected into the RC oscillators of the two self-oscillation chips 4, 6 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; and lamp tube abnormal current detector signals are connected to SD ends of the oscillators of the two self-oscillation chips, thereby controlling quick stop of the oscillation so as to turn off a power tube of the full-bridge inverter. The dual-full-bridge injection phase-locking power synthesis neon lamp is applied to commercial decoration large-power neon lamp advertizing lighting.

Description

technical field [0001] The invention relates to the technical field of electric light source lighting, in particular to a double full-bridge injection phase-locked power synthesis neon lamp. Background technique [0002] Electronic ballasts in the prior art usually use LC or RC oscillators as power-synthesizing neon light sources, and the oscillation frequency generated is affected by poor temperature stability and the power is not stable enough, resulting in a decrease in light intensity. Although the structure is simple and the cost is low.

As a result, the power amplitude of the light will be unbalanced as the frequency changes.
