Led Light Transformer Buzzing

Lutron slide dimmer.

Led light transformer buzzing. Stop led lights from humming and buzzing on dimmer switches. It s a fact of life that an electronic transformer will make a buzzing noise. Even though a transformer has no moving parts these vibration like sounds are quite similar to those produced by generators and motors. The cause is almost always a compatibility issue between the dimmer and the led s driver power supply.

How to size a transformer for landscape lights. Available in a variety of power conversions with short circuit and overload protection for added safety soft start function leading edge and trailing edge options. This is installed in the base of most ceiling luminaires. This is caused by the led driver as described above.

While most led lights are dimmable a common complaint is hearing a buzzing sound coming from the lights when they are dimmed. Add an emi filter at the input output of the transformer. Some led ceiling lights with integrated led s emit a buzzing sound during operation. These are also called ferrite beads or ferrite chokes.

Stop led lights from humming and buzzing on dimmer switches. The 60hz electrical current passing through it causes it to flex slightly and vibrate at that frequency a phenomenon scientists call magnetostriction a metal equipment case containing a transformer will act as a sounding board magnifying the buzz and making it worse. Selected models are dimmer compatible. Even if the driver circuit itself barely hums audibly the base of the luminaire serves as a resonance body in some constructions.

Lutron slide dimmer. Humming and buzzing noises are a common complaint with electrical transformers which are a common sight in both industrial and residential areas. As noted earlier the main reason why your led lights may buzz or flicker is when there are voltage fluctuations in your electric wiring system. Landscape lighting adds safety security and aesthetic appeal.

Change the transformer to one with better emi suppression such as our verbatim led transformer. Item 2 above is only suitable for low voltage led lights.

Minimum ingress protection rated 20. If the disturbance in terms of picture or sound is gone then the reason is most likely evident specifically due to rf radio frequenc y interference or emf electromagnetic frequency. Once your landscape lighting design is complete you can figure out what size of low.
