The voltage drop ‌ is the decrease in voltage caused by the presence of resistance when the current passes through a resistor or conductor in a circuit.

 

The voltage drop is mainly caused by the following reasons.

1.‌Resistor. ‌When the current passes through the resistor, the resistor consumes part of the electric energy, which is converted into heat energy, resulting in lower voltage.

2.Current. The higher the current, the greater the voltage drop.

3.Wire length. The longer the wire length, the greater the resistance, the greater the voltage drop.

4.Wire cross-sectional area. The larger the cross-sectional area of the wire, the smaller the resistance and the smaller the voltage drop.

5.Wire material. Wires of different materials have different resistivity. The greater the resistivity, the greater the resistance, and the greater the voltage drop.

 

Voltage Drop will have a variety of effects on the lamp ‌, mainly including the following aspects of the impact.

1.Brightness drop. When the voltage is below the appropriate level, the brightness of the bulb will decrease. This is because the resistance in the bulb causes the voltage to be distributed to various parts, resulting in insufficient voltage, and the bulb cannot emit enough light.

‌2.Shortened life. Low voltage will cause the life of the lamp to be shortened. The lamp needs more current in the case of low voltage to emit enough light, which will accelerate the aging of the resistance, wire, circuit board and other parts of the lamp, thus shortening the service life of the lamp.

3.Flicker and burn. When the voltage is low to a certain degree, the bulb may flicker and even burn. This is because the lamp needs more current to drive in the case of insufficient voltage, and the temperature will rise, which is easy to cause short circuit or overload, resulting in the lamp burned.

 

The effect of the voltage drop problem on lighting is universal, including on farm lighting. And this impact will cause direct economic losses to farmers. Is there any way to avoid this effect?

 

The answer is yes. After the unremitting efforts of the company's research and development team, we finally developed a Smart Poultry Lighting Control System that can not be affected by the voltage drop. The control system is equipped with self-developed drive power supply and control system. The problem caused by voltage drop to lamps has been completely solved. This control box can not only adjust the brightness and timing of the light, but also realize the sub-area control of the light. The farmers who use Intelligent Poultry Lighting Control System are extremely satisfied with the convenience it brings to the farm.
