What LED beads are used for the charger indicator light? Selection scheme for charger indicator light
The charger indicator light needs to display two states: charging in progress (red) and fully charged (green), with dual color beads being the standard solution. The charger has strict requirements for machine power consumption, and the LED current is usually controlled within 2-5mA. Hongcheng Optoelectronics provides high brightness and low current dual color indicator LEDs for charger manufacturers.
Key points for selecting charger indicator lights
- Dual color scheme: Red and green dual color LED beads display charging status at a single position, with 5mm/3mm direct insertion being the most commonly used and cost-effective.
- Low current: Choose a 2mA high brightness model with a total power consumption of less than 10mW, meeting energy efficiency standards.
- Common Yin/Common Yang: Two color LED beads are available in two types: common Yin and common Yang. Please confirm the driving circuit before placing an order.
- Package selection: Use direct insertion for the shell outlet hole, and 0805 dual color patch for onboard indication.
- Reliability: The internal temperature of the charger is high, and models with a temperature resistance of 85 ℃ or above should be selected.

Frequently Asked Questions
Q: How to achieve the red green color change of the charger?
Answer: Just use a red green dual color LED bead. When charging, drive the red chip, and switch to the green chip when fully charged. For the selection of co yin and co yang, please refer toWorking principle of dual color LED beads.
