Problems solved by technology

[0002] Electronic ballasts in the prior art generally use LC or RC oscillators as the light source, and the oscillation frequency generated is affected by poor stability of temperature changes, and the power is unstable and the light intensity drops. Although the structure is simple and the cost is low

However, if the power supply voltage is low, the current of the device must be increased to obtain high-power lighting, resulting in a sharp increase in the power consumption of the oscillating power tube and an excessive temperature rise, resulting in a change in the oscillating 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

In addition, the non-adjustable high-power glare lighting wastes electric energy, and the glare pollutes the environment and affects vision and hinders work or life.
