An aspect of LED technology that can be confounding is LED drivers. The power to an LED or a string of LEDs is controlled by an electrical device called an LED driver. It is an essential component of an LED circuit, and operating one without the other will lead to system failure.
An EMI filter is included in the majority of electronic devices, either separately or integrated into their circuit boards. The device’s purpose is to lower high frequency electrical noise that might interfere with other equipment.
The Global LED driver EMI filter market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The electromagnetic interference (EMI) filters from TE Connectivity have been made available for use in magnetic resonance imaging rooms where Class II drivers are used to power LED lights.
The LB115 power supply family was introduced by SL Power Electronics with applications for architectural LED lighting in mind. The new power supply series has a built-in EMI filter to comply with EN55015 class B criteria for lighting fixtures and produces 115 watts in a small 2″ x 4″ x 1.2″ footprint.
ANP151, a 150W CC mode LED driver from Amperor, has been released. A two-stage over temperature protection circuit is provided by the ANP151 to avoid a simple shut-off when temperatures rise above anticipated limits. Low Noise EMI Filter is Built-In.
The LP8861-Q1 is an automotive high-efficiency, lowEMI, easy-to-use LED driver with integrated boost/SEPIC converter. It has four high-precision current sinks that can provide high dimming ratio brightness control with a PWM input signal.
