The indicator lights of smart home devices (smart speakers, floor sweepers, smart locks, gateways) are an important part of human-computer interaction, and breathing lights, circular lights, and colorful status lights have become standard. Hongcheng Optoelectronics provides a full range of intelligent indication solutions from single and dual color to RGB iridescence.

Key points for selecting smart home indicator lights

  • RGB Illusion: Choose built-in IC Illusion LED beads (2121/2020/0807) for status colorful display, single line control, saving MCU pins.
  • Breathing effect: Ordinary LED beads can be combined with PWM to achieve breathing light, and choosing a matte gel provides a softer light effect.
  • Side illumination: Choose 4020/0802 side illumination patch for ultra-thin body, with hidden light output.
  • Low power consumption: Choose a 2mA low current model for battery devices.
  • Small package: Choose 0603/0402 patch for compact structure.
