Optical Arc Detection Technology for Power Strips

Technical Background

When household power strips are overloaded or circuits age, dangerous electric arcs may occur. Traditional current detection has slow response times. Optical arc detection monitors abnormal light signals in real-time, cutting power within milliseconds to prevent fires.

Working Principle

  • Infrared Spectrum Sensing
    Arcs emit infrared light at specific wavelengths (800-1100nm). Built-in high-sensitivity IR sensors capture these optical signals in real-time.
  • AI Waveform Analysis
    Machine learning algorithms distinguish normal appliance sparks (<1ms) from hazardous arcs (>4ms), with false alarm rates below 0.1%.
  • Instant Power Cutoff
    Upon detecting hazardous arcs, solid-state relays (SSR) cut power within 15ms – 10x faster than mechanical relays.

Key Advantages

  • 15ms Ultra-Fast Response
    (vs. 200ms in traditional solutions)
  • Space-Efficient Design
    Optical sensors occupy <1cm³
  • Electromagnetic Immunity
