Deep Technical Specifications
Voltage and Current Requirements
This 75 3 led 10w cob dc module is designed for DC power, typically at 24V. Operating within the recommended voltage range ensures stable output and prevents thermal stress on the COB array.
Optical Performance
With multiple COB LEDs arranged in a 3 chip layout, the module produces directional light suitable for task and area lighting. Color temperature and CRI vary by version, so confirm model details to match your illumination needs.
Mechanical and Thermal Design
The compact form factor relies on a metal core and finned housing to manage heat. Proper airflow and mounting surface temperature control are important to maintain rated lifespan and avoid lumen deprecation.
Installation and Power Wiring Guidelines
Wiring Diagram and Polarity
Follow the polarity marking on the cable or connector; reverse polarity can damage the module. Use appropriately rated conductors and strain relief for reliable long term operation.
Mounting Recommendations
Install on a thermally conductive surface when possible, and ensure screws are tightened to specified torque. Avoid mechanical tension on the wiring to prevent fatigue at solder joints.
Performance in Real Applications
Industrial and Workshop Use
Factories and workshops benefit from the high lumen density, enabling fewer fixtures to cover the same area. The DC input simplifies integration with battery backed systems or solar setups.
Retrofit and Modular Lighting Projects
Retrofit kits often adapt this module to legacy fixtures, allowing upgrades without full replacement. Thermal design must be verified in sealed fixtures to avoid overheating.
Key Takeaways and Recommendations
- Confirm DC voltage compatibility with your power source before installation.
- Ensure adequate thermal management to reach the rated L70 lifespan.
- Use correct polarity and strain relief wiring practices.
- Evaluate IP rating and thermal environment for your specific setting.
- Compare luminous efficacy and footprint against existing fixtures.
FAQ
Reader questions
Can I use this module with a 12V power supply instead of 24V?
Operating the 75 3 led 10w cob dc module below the rated voltage can reduce brightness and may cause unstable current. Check the driver or converter compatibility, or choose a module designed for 12V systems.
What is the expected lifespan under continuous operation?
With proper heat sinking and ventilation, the module can exceed 30,000 hours at rated conditions. Higher ambient temperatures or poor cooling may shorten this significantly.
Is this module suitable for outdoor or wet environments?
The standard enclosure is IP20, intended for indoor use. For outdoor or high humidity locations, select a version with higher IP rating or add appropriate protective housing.
How does the light output compare to traditional metal halide?
The 900–1100 lm output can match many small metal halide fixtures while consuming less power and warming up instantly. Verify mounting height and optics to achieve desired coverage.
