- Easy Installation: Designed for straightforward and safe connection to compatible lamp fixtures.
2. Setup and Installation
These LED chips are designed for easy integration into existing or new lighting fixtures. Proper installation is crucial for safety and optimal performance.
Safety Precautions:
- Always disconnect power to the fixture before installation or maintenance.
- Ensure proper electrical insulation and connections to prevent short circuits.
- Handle LED chips by their edges to avoid touching the light-emitting surface.
- Do not exceed the specified voltage (150-170V) or wattage (60W) per chip.
Installation Steps:
- Prepare the Fixture: Ensure the lighting fixture is clean, dry, and has adequate space for the LED chip.
- Mount the Chip: Securely attach the LED chip to the fixture's heat sink or mounting surface. The aluminum substrate is designed for heat dissipation, so good thermal contact is essential.
- Connect Wiring: Connect the positive (+) and negative (-) terminals of the LED chip to the corresponding power supply wires. Refer to the markings on the chip for correct polarity.
- Test: Once all connections are secure and insulated, restore power and test the light.

5. Troubleshooting
If you encounter issues with your EVTSCAN COB LED chips, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| LED chip does not light up. | No power, incorrect wiring, faulty power supply, or damaged chip. |
|
| Light is dim or flickers. | Insufficient voltage, unstable power supply, or poor connection. |
|
| Chip overheats. | Inadequate heat dissipation, excessive voltage/current. |
|
If problems persist after following these steps, contact customer support for further assistance.
