COB (Chip-on-Board) technology concentrates multiple LED diodes into a single emissive surface, resulting in a uniform luminous flux and high efficiency of up to 150 lm\/W. The compact 19x19mm format allows integration into small spaces without compromising performance.\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\u003eLuminous flux of 1950-2050 lm at only 15W consumption — powerful lighting with low energy consumption\u003c\/li\u003e\n\n\u003cli\u003eLuminous efficiency of 140-150 lm\/W — superior performance compared to conventional LED solutions of the same power\u003c\/li\u003e\n\n\u003cli\u003eCircular emissive surface with gel protection — uniform light, without unwanted spots or shadows in the application\u003c\/li\u003e\n\n\u003cli\u003eIntegrated aluminum support with mounting slots — efficient thermal dissipation and easy mounting on a heatsink\u003c\/li\u003e\n\n\u003cli\u003eColor rendering index Ra over 80 — colors are rendered correctly, essential for advertising and showcases\u003c\/li\u003e\n\n\u003cli\u003eUltracompact dimensions 19x19mm, 1mm thickness — compatible with a wide range of existing lighting fixtures and modules\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 COB LED chip is powered by 45V DC with a current of 300mA via a compatible LED driver — the positive and negative connections are marked in opposite corners of the aluminum support. Mounting is done on a passive or active heatsink, obligatorily using thermal paste, to ensure the dissipation of heat generated at high power. It does not require additional soldering on the circuit; the power contacts can be connected directly via wires or specific terminals.\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\u003eDo I need a special driver for this 15W COB LED chip?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, the chip requires an LED driver that supplies 45V DC at 300mA.
