30W COB LED Chip for Professional Lighting and Custom Projects
The 30W COB LED chip with an active diameter of 14.8mm is a compact and efficient light source designed for building or replacing high-power lighting fixtures. With a luminous flux of up to 4000 lumens and an efficiency of 140-150 lm/W, this chip offers high brightness in a miniaturized format, ideal for technical lighting projects, illuminated signs, and customized lighting systems.
What you get with this product
- Luminous flux of 3900-4000 lm at only 30W consumption — power/light ratio comparable to conventional 200W sources
- Active surface covered with protective gel — increased mechanical resistance and uniform light dispersion
- Aluminum support with mounting slots — allows direct attachment to a heatsink without additional adapters
- Clearly marked polarity in the corners — quick connection without the risk of accidental contact reversal
- Color rendering index Ra greater than 80 — colors of illuminated objects appear natural and clear
- Compact 19x19mm format — easily integrates into lighting fixtures with limited space or DIY projects
How it works and how to install it
The 30W COB LED chip is powered at 30V DC with a current of 900mA, via an external LED driver compatible with these parameters. Mounting is done on an aluminum heatsink with thermal paste between the chip surface and the heatsink, to ensure proper heat dissipation and extend the component's lifespan. The power contacts, marked with plus and minus in the corners of the board, connect directly to the driver output, observing the indicated polarity.
Frequently Asked Questions
Do I need a heatsink for this LED chip?
Yes, mounting on a heatsink with thermal paste is mandatory. At 30W, the chip generates significant heat, and without proper dissipation, its lifespan decreases considerably.
What LED driver is compatible with this 30W chip?
A driver with a 30V DC output and a constant current of 900mA is required. Always verify that the chosen driver is sized for 30W power.
Can this chip be used outdoors or in humid environments?
No. The chip has no IP protection and is not intended for use in humid environments or direct exposure to weather. It is used exclusively inside a properly sealed lighting fixture.
