Outdoor lights are susceptible to transient spikes by lightning strikes that are inductively coupled onto power lines. Surges can be caused by direct lightning, indirect lightning or switching OFF/ON of mains supply. Besides surges, if HV line touches LV line or if neutral connection is weak or floating the phase- Neutral voltages can go higher than prescribed limits of luminaire. For the purpose of this article we will focus on surge protection.

These surge voltage transients can destroy LED power supplies as well as the LED’s themselves. Due to the sensitive nature of LED lights, we need to provide over voltage, over current, surge protection for LED lighting systems ,The most common type of surge protector contains a component called a metal oxide varistor or MOV, which diverts the extra voltage & energy away from the device it is protecting. In case of LED Lights, it will protect LED Driver or LED itself.

Pyrotech provides SPD modules which shall give protection in excess of 10kV. This protection is there between Phase-Neutral, Neutral-Earth & Phase-Earth. We offer these modules inbuilt inside the outdoor luminaires such as street lights, flood lights etc.
