What is an LED emergency driver?

2023-02-13

In contrast to LED drivers, the LED emergency driver is used to transform a regular light into an unmaintained emergency light. The power source for an LED is monitored and controlled by an LED emergency driver.

This driver powers the LED from the mains when the power is on and continues to recharge the battery that is built into it.

In the event that the primary sources fail for whatever reason, the LED emergency driver instantly switches the power supply to the battery and prevents the light from turning off.

In different with standard LED drivers, these drivers run on a battery and provide the LED fixture with the specified power during a power loss. These drivers are typically set up to provide the LED fixture less power than is necessary.

To reduce battery charge usage and extend the amount of time the light will be illuminated on battery power, less power is delivered to LED fixtures.

However, the energy source is modifiable, and some producers offer pre-tailored Led Emergency Drivers based on consumer demands.

Normally we require the LED lighting with external LED driver to match our LED emergency conviersion kits. You can see the wiring as below for reference

After covering the fundamentals, let's get into the specifics that you should consider while choosing LED emergency drivers.


Voltage Request

Voltage is a quantitative measure of the potential difference between two points and can be thought of as an electromotive force. It enables a smooth passage of charge to ensure the lightning LED. The voltage that electrical equipment will utilize is indicated by the letter "V."

Each LED fixture has a particular voltage. Be sure to understand the voltage requirements before choosing an LED emergency driver.

There are two distinct voltage kinds. The voltage that an LED emergency driver can accept as input is known as input voltage, and the voltage that the driver can deliver is known as output voltage, also referred to as Voltage flow (Vf) or Output Voltage.

It is essential that the output voltage flow corresponds to the voltage specifications of the LED fixture.

In the Naips Emergency Led Driver,

DC output of full wattage emergency driver 220-240V.

DC output of Non-full wattage emergency led driver is 9-175V.

As a result, the voltage range can be adjusted to precisely meet the needs of the LED fixture.

However, an LED emergency driver cannot be installed with any LED fixture that requires a voltage that is either lower or higher than the specified range.


Wattage Request

Power is measured in watts and is expressed as wattage. It can be defined as the quantity of energy needed to run an electrical equipment or appliance.

The power released each second is measured in watts. Voltage and current are multiplied to determine wattage, demonstrating their direct link.

Selecting emergency drivers with the highest wattage is crucial. It should be greater than what the LED light requires in terms of wattage. Only then can LED emergency drivers function smoothly.


Safety Request

Electric appliances, especially lighting fixtures, must be safe. As a result, each LED emergency driver has a rating for IP or CB, EMC, SAA, or UL. Naips already has approved certificates you need. Based on the environment in which it will be installed and taking the IP rating of an LED emergency driver into account, you should choose an LED driver.


Transfer your LED fixtures into LED EMERGENCY LIGHTING is more and more popular and important to avoid power failure issue. No matter it is commercial lighting or household lighting. Naips LED emergency driver can help you improve this function easily and safety.
