What LED beads are used for the power board indicator light? Selection scheme for power board indicator lights

发布于: 2026-07-29 22:38

The power board indicator light is used to display the power status, normal output, and fault alarm. It lights up 24 hours a year and has the highest requirements for the lifespan and low light decay of the lamp beads. The dedicated indicator LED for Hongcheng Optoelectronic Power Board adopts A-grade chips and 99.99% gold wire packaging to ensure continuous illumination without attenuation for many years.

Key points for selecting power board indicator lights

  • Long lifespan: The power indicator light is on all year round, and a low light decay model must be selected, with a light decay rate of less than 30% after 50000 hours.
  • Package selection: 5mm/3mm direct insertion is used for panel outlet holes, and 0603/0805 patch is used for onboard.
  • Color matching: green=power supply normal, red=fault, yellow=standby; Single position dual color optional red and green dual color LED beads.
  • Voltage resistance and heat dissipation: Pay attention to the insulation and creepage distance of the lamp beads on the high-voltage power board, and insert the long legs directly for easy bending and shaping.
  • Wide voltage: The 12V/24V power supply system can be customized with high-voltage LED components with current limiting resistors.

Frequently Asked Questions

Q: If the power indicator light is on all year round, how long will the light bulb dim?
Answer: Ordinary LED beads show significant light decay within 1-2 years, while industrial grade LED beads with low light decay after 50000 hours have a light decay of less than 30%. They can be used for more than 5 years when lit for 24 hours. see detailsRecommended low-power and long-life models.
