10W COB LED Chip for Professional Lighting and DIY Projects
The 10W COB LED chip with a 19mm diameter is a compact and efficient light source, designed for integration into luminaires, light boxes, and custom lighting systems. COB (Chip on Board) technology provides a uniform luminous flux of up to 1410 lm from an emitting surface of only 14.8mm in diameter, with no visible light spots. With an efficiency of 140-150 lm/W, this chip is a solid choice for builders and designers who need real power in a miniaturized format.
What you get with this product
- Uniform and dense light — the round surface with protective gel eliminates spots or areas of uneven intensity
- High efficiency of 140-150 lm/W — consume 10W and get up to 1410 lm, equivalent to a 75-80W incandescent bulb
- Integrated aluminum substrate — dissipates heat efficiently and extends the chip's lifespan when properly mounted on a heatsink with thermal paste
- Compact 19x19mm format — integrates into small spaces without compromising light performance
- Clearly marked polarity — + and - contacts are positioned in opposite diagonal corners, reducing the risk of incorrect connection
- Application versatility — compatible with indoor lighting projects, light signs, DIY spotlights, and custom lighting systems
How it works and how to install it
The COB LED chip operates at 30V DC with a current of 300mA, so it requires an external LED driver to supply the corresponding voltage and current — it does not connect directly to the mains. Installation is done by applying a thin layer of thermal paste between the substrate and the aluminum heatsink, after which the chip is mechanically fixed and the wires are connected to the + and - contacts marked on the corners of the substrate. A heatsink is mandatory: without proper heat dissipation, the junction temperature will rise rapidly and significantly reduce the chip's lifespan.
Frequently Asked Questions
Do I need a separate driver for this LED chip?
Yes, the chip operates at 30V DC / 300mA and requires a compatible LED driver — it does not power directly from 220V.
Is it mandatory to use a heatsink and thermal paste?
Yes, this chip generates considerable heat at 10W. Without an adequate heatsink and thermal paste, the chip will overheat and be damaged prematurely.
Can it be used outdoors or in humid environments?
It is not recommended for outdoor or humid environments — the chip does not have IP protection and must be mounted in appropriate enclosures that provide the necessary protection.
