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.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-benefits\"\u003e\n\n\u003ch2\u003eWhat You Get with This Product\u003c\/h2\u003e\n\n\u003cul\u003e\n\n\u003cli\u003ePure and saturated colors — the three R, G, B channels operate independently, allowing any shade to be obtained through PWM mixing\u003c\/li\u003e\n\n\u003cli\u003eCompact 28mm COB format — integrates into standard RGB projector and spotlight housings without mechanical modifications\u003c\/li\u003e\n\n\u003cli\u003eDirect replacement of damaged chips — save the cost of an entire projector by replacing only the LED source\u003c\/li\u003e\n\n\u003cli\u003e6W power in a single module — concentrated luminous flux, ideal for accent effects and directed decorative lighting\u003c\/li\u003e\n\n\u003cli\u003eStar-type metal substrate — efficiently dissipates heat and extends the chip's lifespan in continuous operation\u003c\/li\u003e\n\n\u003cli\u003eCompatible with standard RGB drivers and controllers — connects to any driver with separate channels or DMX controller with constant current output\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-how\"\u003e\n\n\u003ch2\u003eHow it Works and How to Install it\u003c\/h2\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-faq\"\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat driver do I need for this 6W RGB COB LED chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYou need a three-channel constant current RGB driver, rated for 2W per channel (red, green, blue).
