4. Installation
Proper installation is crucial for the performance and longevity of your LED module. Please follow these steps carefully:
- Prepare the Mounting Surface: Ensure the surface where the LED module will be mounted is clean, flat, and capable of dissipating heat effectively. A heatsink is mandatory for high-power LEDs.
- Apply Thermal Paste/Pad: Apply a thin, even layer of high-quality thermal paste or attach a thermal pad to the back of the LED module or the heatsink. This ensures efficient heat transfer.
- Mount the LED Module: Securely attach the LED module to the heatsink using appropriate screws or clamps. Ensure firm contact between the module and the heatsink.
- Wiring Connections:
- Identify the positive (+) and negative (-) terminals on the LED module. These are typically marked on the module itself.
- Connect the positive (+) output from your constant current LED driver to the positive (+) terminal on the LED module.
- Connect the negative (-) output from your constant current LED driver to the negative (-) terminal on the LED module.
- Ensure all connections are secure and insulated to prevent short circuits.

Figure 2: Another LED module variant (MT-CM3834-03) with R+ and R- terminals, also indicating polarity. - Power Supply Compatibility: Verify that your LED driver provides the correct voltage (32-36V for 10 series) and current for the specific configuration of your LED module (e.g., 10 series 7 parallel). Incorrect power supply can damage the LED.
- Test the Installation: Before final assembly, briefly power on the LED module to confirm it illuminates correctly. Observe for any flickering or unusual behavior.
Understanding LED Configurations:
- 10 Series 7 Parallel (10串7并): This configuration uses 70 chips, with 10 chips connected in series to form a string, and 7 such strings connected in parallel. This is a common configuration for 120W modules.
- 8 Series 12 Parallel (8串12): Another possible configuration, using 96 chips (8 chips in series, 12 strings in parallel). This would require a different operating voltage and current.
- Detailed Chip Information: The luminous area of the LED chip package is approximately 17mm x 12mm.
5. Operation
Once properly installed and connected to a compatible constant current LED driver, the module is ready for operation.
- Power On: Activate the power supply connected to the LED driver. The LED module should illuminate instantly.
- Monitoring: During operation, ensure the heatsink remains within acceptable temperature limits. Excessive heat can degrade performance and shorten lifespan.
- Light Output: The module provides a high-intensity white light (8500K). Avoid direct eye exposure.
6. Maintenance
Minimal maintenance is required for this LED module, but adhering to these guidelines will help ensure its longevity:
- Cleaning: Periodically, gently clean the surface of the LED module and heatsink to remove dust and debris. Use a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, ensuring no moisture enters the electrical connections. Always disconnect power before cleaning.
- Thermal Management: Regularly check that the heatsink is free from obstructions and that airflow (if applicable, e.g., with a fan) is not impeded.
- Connection Check: Occasionally inspect wiring connections for any signs of wear, corrosion, or loosening.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LED does not light up | No power; incorrect wiring; faulty LED driver; damaged LED module. | Check power supply. Verify positive/negative wiring. Test LED driver. Replace LED module if damaged. |
| LED flickers or dims | Unstable power supply; incorrect current/voltage from driver; poor connection; overheating. | Ensure stable power. Verify driver output matches LED specs. Check all connections. Improve heat dissipation. |
| LED overheats quickly | Insufficient heatsink; poor thermal paste application; inadequate airflow. | Ensure heatsink is adequately sized. Reapply thermal paste. Improve ventilation around the heatsink. |
| Reduced brightness over time | Normal aging; prolonged overheating; operating outside specified parameters. | Ensure proper thermal management. Verify operating parameters. Consider replacement if lifespan is exceeded. |
8. User Tips
- Compatibility Check: Before purchasing or installing, always verify the specific part number and electrical specifications (voltage, current, series/parallel configuration) of your existing projector's light source to ensure compatibility with this LED module. For example, if replacing a "MT-CM6040-01" in a "Jifar T6" projector, confirm the voltage and wattage requirements.
- Power Supply Matching: Ensure your LED driver's output voltage and current precisely match the requirements of the LED module's configuration (e.g., 12 series 24 parallel will have different voltage/wattage needs than 10 series 7 parallel).
- Thermal Management is Key: High-power LEDs generate significant heat. A robust heatsink and, if necessary, active cooling (fan) are essential to prevent premature failure and maintain brightness.
