6W RGB COB LED Chip for Multicolor Lighting
The 6W RGB COB LED chip with a 28mm diameter is the basic component for multicolor lighting projects, light scenographies, or replacing damaged sources in RGB projectors. The COB format integrates all three color channels — red, green, and blue — into a single compact source, providing homogeneous color mixing and high luminous density for its size. It is frequently chosen by electronics engineers, makers, and technicians who build or repair decorative and architectural lighting equipment.
What You Get with This Product
- Pure and saturated colors — the three R, G, B channels operate independently, allowing any shade to be obtained through PWM mixing
- Compact 28mm COB format — integrates into standard RGB projector and spotlight housings without mechanical modifications
- Direct replacement of damaged chips — save the cost of an entire projector by replacing only the LED source
- 6W power in a single module — concentrated luminous flux, ideal for accent effects and directed decorative lighting
- Star-type metal substrate — efficiently dissipates heat and extends the chip's lifespan in continuous operation
- Compatible with standard RGB drivers and controllers — connects to any driver with separate channels or DMX controller with constant current output
How it Works and How to Install it
The 6W RGB COB LED chip has three anodes and a common cathode (or vice versa, depending on the chosen driver configuration), with each color channel requiring a separately controlled constant current. Mounting is done by thermal bonding to an appropriate heat sink or directly into the original housing of the repaired device, using thermal paste for optimal heat transfer. Electrical connections are made by soldering to the marked pads on the metal substrate — an operation accessible to anyone with basic electronics knowledge.
Frequently Asked Questions
What driver do I need for this 6W RGB COB LED chip?
You need a three-channel constant current RGB driver, rated for 2W per channel (red, green, blue). A PWM RGB controller with constant current output is the most common option.
Does this RGB chip have a common cathode or common anode?
Based on the product images and the standard configuration of this type of RGB COB chips, the pads are separated by R, G, B channels — check the markings on the metal substrate before connecting and consult the datasheet of the driver used.
Do I need a heat sink for this 6W chip?
Yes, at 6W it is necessary to mount it on a heat sink with thermal paste. Without adequate heat dissipation, the junction temperature will rise rapidly, and the chip can irreversibly degrade in a short time.
