40W COB LED Chip for Professional High-Intensity Lighting
The professional 40W COB LED chip with an active diameter of 14.8mm offers high luminous flux in a compact area, ideal for lighting projects requiring high light density. COB (Chip-on-Board) technology ensures uniform emission, without spots or dark areas. Suitable for building or replacing light sources in luminaires, advertising lightboxes, and projection systems.
What you get with this product
- Luminous flux of up to 5560 lm at 40W — luminous efficacy of 140-150 lm/W, more light for the same energy consumption
- Round active surface of 14.8mm with gel protection — uniformly distributed light, without visible hot spots
- Aluminum support with mounting slots — direct mounting on heatsink, efficient thermal dissipation without overheating
- Clearly marked + and - contacts in opposite corners — simple connection, no risk of polarity reversal
- Compatible with multiple applications — luminaires, illuminated signs, custom systems, professional DIY lighting projects
- Color rendering index Ra over 80 — colors are rendered correctly, also suitable for commercial or exhibition lighting
How it works and how to install it
The COB LED chip is powered by 36V DC with a current of 1050mA, through a compatible LED driver (not included). Installation is done on an aluminum heatsink using thermal paste — this ensures heat transfer and prolongs the lifespan of the chip. Connections are made by soldering or clamps to the contacts marked in the corners of the aluminum support, observing the indicated polarity.
Frequently Asked Questions
Do I need a separate heatsink for this LED chip?
Yes, the 40W chip generates significant heat and requires mandatory mounting on an aluminum heatsink with thermal paste to operate within normal parameters and avoid damage.
What LED driver is compatible with this 40W COB chip?
An LED driver with a 36V DC output and a constant current of 1050mA (approximately 38-40W) is required. The driver is not included in the package and must be purchased separately.
Can this LED chip be used outdoors or in humid environments?
No. The chip has no moisture protection and should not be exposed to humid environments, dust, or extreme temperatures. It is intended exclusively for use inside luminaires or protected enclosures.
