26mm 5W COB LED Chip for Lighting Projects
The 26mm 5W COB LED Chip is a compact and efficient light source, designed for technical lighting projects, custom luminaires, and illuminated signage systems. COB (Chip on Board) technology ensures uniform light distribution across the entire active surface, without visible light spots. With a luminous flux of 580-600 lm at only 5W consumed, this chip offers an efficiency-consumption ratio of 140-150 lm/W.
What You Get with This Product
- Uniform and flicker-free light — COB technology eliminates light spots and provides a homogeneous beam, ideal for demanding visual applications
- High efficiency — 140-150 lm/W means more light for the same energy consumption compared to classic LEDs
- Integrated thermal support — the round aluminum alloy substrate with mounting slots facilitates heat dissipation and extends the chip's lifespan
- Compatible with multiple applications — suitable for luminaires, advertising lightboxes, decorative lighting systems, or DIY electronic projects
- Simple installation with 4 clear contacts — the 2+ / 2- configuration allows for quick connection without risk of polarity confusion
- Gel protection on the active area — the 19mm LED die is covered with protective gel, reducing the risk of mechanical damage during handling
How it Works and How to Install
The 5W COB LED chip is powered by 15V DC via a compatible LED driver, with a working current of 300mA — it does not connect directly to the mains. Installation is done on a metal heatsink with thermally conductive paste to ensure the dissipation of heat generated during operation. The electrical connection is made via the 4 soldering pads marked with polarity (2 positive, 2 negative), accessible on the aluminum substrate.
Frequently Asked Questions
Do I need a separate heatsink for this LED chip?
Yes, the integrated aluminum substrate is not sufficient for complete heat dissipation at maximum power. Mounting on an external heatsink with thermally conductive paste is recommended.
Which LED driver is compatible with this 5W chip?
An LED driver with a 15V DC output voltage and 300mA current is required. Using an incompatible driver can damage the chip.
Can this COB LED be used outdoors or in wet environments?
No. The chip has no moisture protection and should not be exposed to wet environments, condensation, or excessive heat sources.
