What You Need to Know About Electrostatic Discharge Protection for LEDs

Don’t let static electricity short-circuit your LEDs by taking these electrostatic discharge precautions during installation.

What Is Electrostatic Discharge?

Electrostatic discharge (ESD) occurs when two differently charged objects come into close proximity or contact with each other, resulting in rapid current transfer. If you’ve ever walked across a carpet and then felt a zap after touching a metal surface, you’ve experienced an ESD event. This phenomenon is particularly relevant anytime you’re working with electronics because even discharges imperceptible to humans can be enough to damage circuitry.

Anytime you see this ESD susceptibility symbol printed on component packaging or documents, you need to follow ESD precautions:

LEDs are best understood as electronic devices engineered to output light, meaning that, unlike a lightbulb in your home, they’re susceptible to ESDs. All LEDs are sensitive to ESDs, but the risk of a discharge can fluctuate depending on several variables, including:

Humidity
Temperature
Materials in close proximity

The Dangers of ESD Events

Depending on the frequency and intensity of an ESD event, LED and critical control components (the brain of the control circuitry) can be fried, resulting in diminished brightness, color shifts, or complete operational failure. Repeated exposure to minor ESD events may not result in immediate failure but can degrade performance over time. ESD events also have the potential to ignite flammable materials in the vicinity.

A Primer on Electrostatic Discharge Protection Strategies for LEDs

You can take relatively simple steps to minimize the chances of an ESD zapping your LEDs. The most important time to take these precautions is when you’re installing or handling the luminaire’s wiring or internal components during installation or if you have to open up the unit. These precautions not only minimize operational risks but also protect LED systems against natural degradation.

Stay Grounded

Since ESD occurs when two objects of different voltage potentials come into contact, to prevent the zap from happening, all you need to do is make sure the surface you are going to come into contact with has the same potential as your body. Therefore, you want both the light and your own body to be properly grounded. Ground all equipment you’re handling before it comes into contact with any wiring or electrical components. Whether you’re installing LEDs on a boat, truck, or UTV, touch any attached metallic surface that is connected to the chassis ground to ensure you’re truly grounded.

Antistatic Tools

Instead of worrying about grounding equipment before use, you can also invest in static dissipative, antistatic, and ESD-safe tools.

ESD Wrist Straps

Wearing a grounded ESD wrist strap makes it easy to stay grounded, preventing static buildup on your body from continuous body movement.

ESD Protective Clothing

You can also wear an ESD gown and shoes to further minimize the risks of electrostatic discharge.

Monitor Humidity

If you can monitor and adjust humidity in a controlled environment, maintaining humidity levels at a minimum of 50 percent can help minimize the likelihood of ESDs.

Install an ESD Workstation

If you regularly handle LEDs, it may be worthwhile to set up an ESD-safe workstation with an ESD mat on the work surface and an ESD floor mat. By connecting these mats to the ground (a copper rod cast in the ground), you can safely dissipate static charges.
