Undergrad Fluorescent lamps And Fan remote

Click For Summary
SUMMARY

The discussion centers on the interference caused by fluorescent lamps on the operation of infrared (IR) remote controls for fans. Users noted that the fan remote works effectively at a longer distance when the fluorescent lamps are off, indicating that the lamps generate noise that disrupts the IR signals. Specifically, the switching of fluorescent lamps creates infrared, optical, or radio frequency (RF) pulses that increase the noise floor, reducing the sensitivity of the IR receiver in the fan remote.

PREREQUISITES
  • Understanding of infrared (IR) remote control technology
  • Knowledge of fluorescent lamp operation and electromagnetic interference
  • Familiarity with noise floor concepts in signal processing
  • Basic electronics principles related to light and signal transmission
NEXT STEPS
  • Research the impact of electromagnetic interference on remote control devices
  • Learn about different types of lighting and their effects on electronic devices
  • Explore solutions for reducing interference from fluorescent lamps
  • Investigate alternative lighting options that minimize remote control disruption
USEFUL FOR

Electronics enthusiasts, home automation specialists, and anyone experiencing interference issues with remote controls due to fluorescent lighting.

Hi everyone. I hope you are doing great . I recently saw something interesting and had a question. I use fluorescent lamps in my room, and when I use the remote fan, it works at a shorter distance, but when the lamps are off, the remote works at a longer distance. What do fluorescent lamps do that affects the operation of the remote?

I expect the fan uses an IR remote control.
The switching of the FL causes IR, optical, or RF pulses, that are picked up by the IR receiver. That makes it less sensitive because the noise floor is higher.
