4. Setup and Installation

Follow these steps for safe and proper installation of the LED COB chip:

Disconnect Power: Before beginning any installation, ensure the power supply to the fixture is completely turned off.
Secure the LED Bead: Carefully place and secure the LED COB chip in the appropriate position within your lighting fixture. Ensure it is firmly mounted to allow for proper heat dissipation.
Connect Power: Once the LED bead is securely in place, connect the power supply according to the electrical specifications (refer to Table 2). Pay close attention to positive (+) and negative (-) terminals.
Ready for Use: The unit is ready for use once power is connected and all safety checks are performed.

5. Operation

Once installed and powered, the LED COB chip will provide illumination. No specific operational controls are typically associated directly with the chip itself, as its function is to emit light when powered. Operation is generally controlled by the external fixture's switch or dimmer.

6. Maintenance

The XIANGCLEAR LED COB Chips are designed for long-term, maintenance-free operation under normal conditions. To ensure optimal performance and longevity:

Keep Clean: Periodically clean the surface of the LED chip and surrounding fixture from dust and debris using a soft, dry cloth. Ensure power is off before cleaning.
Ensure Ventilation: Always ensure that the installation location provides sufficient ventilation and heat dissipation to prevent overheating.
Avoid Physical Damage: Handle the chips with care to avoid physical damage to the luminous surface or electrical contacts.

7. Troubleshooting

If you encounter issues with your LED COB chip, refer to the following troubleshooting guide:

Lamp does not light up:
- Check the power supply to ensure it is active.
- Verify all electrical connections are secure and correctly wired (positive to positive, negative to negative).
- Ensure the correct voltage and current are being supplied to the chip as per specifications (Table 2).
Excessive heating:
- Ensure the installation location provides sufficient ventilation.
- Check that the heat sink (if applicable) is properly attached and sized for the chip's wattage.
- Verify the input current and voltage are within the specified limits.
Uneven light distribution:
- Adjust the LED bead's angle or position within the fixture.
- Inspect the luminous surface for any obstructions or damage.
- If the issue persists, consider replacing relevant components or the LED chip itself.
