Electronic Ballasts for UVC Germicidal Lamps

Light Sources and LightTech offer an extensive line of electronic ballasts, covering a wide range of UVC germicidal lamps.

Choosing the right ballast is essential because system performance is dependent on the interaction between the lamp and ballast.

Here is why:
As elements in an electrical circuit, germicidal lamps are referrred to as “active” elements because they generate harmonic and transient voltages and currents. They exhibit a seemingly strange characteristic – the voltage decreases with increasing current. This process is known as negative AC resistance. Therefore, gas discharge devices, such as germicidal lamps, are inherently unstable; once lit, the current increases without limit unless other circuit elements - ballasts - are used to restore and maintain operation.

At Light Sources companies, we have created a true system design by engineering ballasts that matchour lamps. Our series of electronic high frequency ballasts provide our clients with an optimal
performance germicidal system.

Purpose of Ballasts

An electronic ballast serves two main purposes. One, it provides enough voltage to break down the rare gas contained in the lamp to initiate electron flow (ARC), and two, it limits the current flow.

For some UVC germicidal lamps, the ballast also needs to provide heat to the electrodes at the lamp ends. This is important for lamps that are turned on and off more than three times per day.

Ballast Benefits of Electronic HF Operation:

High efficiency
Light weight
Small size
Hight power factor
Insensitive to line voltage variation
Operation on multiple voltages
