To fully protect the investment in your LED lighting systems, be sure your installation includes complete protection with zero-crossing contactors (see our previous post “How to solve the mysterious LED electrical network problem”), surge protection devices, and voltage threshold tripping devices.
What can be done to protect an LED in a circuit?
A metal oxide varistor (MOV) placed across the input helps to provide overvoltage protection in the LED module. The device may also be placed after the MOV. Many equipment manufacturers prefer protection circuits combining resettable overcurrent protection devices with upstream fail-safe protection.
Do LED lights need a surge protector?
The short answer: we recommend buying a surge protector when you’re replacing HID lamps (high intensity discharge) with LED lamps (light emitting diode). … “Dirty power” – or surges in electricity – caused the LED lamps to burn out. That’s where a surge protector can help.
How can we protect led from too much current?
Resistors limit the flow of electrons in the circuit and protect the LED from trying to draw too much current.
Can you cover LED lights?
Don’t cover LEDs with fabric.
It can be tempting to toss a shirt or scarf over those bright lights to block them from view, but it’s not a great idea. Fabric tends to trap heat, which could cause your electronic item to overheat and even become a fire hazard.
Can high voltage damage LED lights?
Yes, definitely the high voltage will damage the LED lights. If the deviation in the voltage is more than 10%, plus the LED BULB will be fused off. The electronic parts inside the bulb gets damaged due to the high voltage.
What safety device is required when connecting a LED?
For LED ‘light bulb’ format light sources, these are generally designed to be as cost effective as possible, but for safety, a fuse and an MOV are still necessary at the input.
Do LED lights cause harmonics?
Light Emitting Diode (LED) lamps are being increasingly used in many applications. These LED lamps operate using a driver, which is a switching device. Hence, LED lamps will be a source of harmonics in the power system. These harmonics if not well treated, may cause severe performance and operational problems.
What do the lights on a surge protector mean?
The red light indicates that the surge protector is on. The green light indicates the ground is on and is working.
Are LED lights voltage sensitive?
Because LEDs are extremely sensitive to under- or over-voltage, you must calculate voltage drop carefully and correct for it. … Sometimes it works as if the source is an incandescent lamp; other times, if the voltage is too low, for example, standard dimmers do not work.
What happens if you put too much voltage through an LED?
In the most simple terms: it will kill the LED. However things are really not that simple. First off, an LED is a current driven device, not a voltage driven device. … Of course, too much voltage will kill it – but too much current, regardless of the voltage, will kill it.
What does a LED do in a circuit?
Light-emitting diodes (LEDs) and lamps produce light when a current flows through them in the forward direction. LEDs and lamps are often used for indicator lights in electrical equipment, such as computers and television sets. As LEDs use a much smaller current than other types of lighting, their use is increasing.
Do LEDs work on AC or DC?
In most applications, LEDs are driven by a DC power supply, but AC offers several significant advantages. … LEDs are usually considered to be DC devices, operating from a few volts of direct current.
Can LED strip lights catch fire?
The LEDs will not give off enough heat to catch on fire or burn your bed, ever. This project could easily be the fusion of 2 well engineered products to do something cool without any risks!
Should I unplug my LED lights at night?
Fortunately, because they are cool to the touch and simply dim over time, LED lights do not present these hazards. With this in mind, it’s a good idea to turn off your LED lights at night so the transformer has time to cool down and avoid the risk of overheating.
