Connection is made by soldering or screwing onto the pads marked with + and -, to a stable 3.2V-3.6V power supply with a driver or current-limiting resistor. For applications with multiple modules, the chips can be connected in series or parallel using the side pads of the star board.\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 separate driver for this 3W LED?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, the chip requires a constant current source or an LED driver that provides 500-700mA at a voltage of 3.2V-3.6V; direct connection to a battery without current limitation can damage the diode.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the included aluminum heatsink sufficient, or is additional cooling needed?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eFor continuous operation at a nominal power of 3W, it is recommended to apply thermal paste and mount the star board on an external heatsink or a metal surface; for intermittent use or outdoors, the included support may be sufficient.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I connect multiple such chips together?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, the star boards are designed for series or parallel interconnection via the side pads, as seen in the presented multi-module configurations; make sure the chosen driver supports the total voltage and current of the configuration.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-specs\"\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\n\u003ctable\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eSKU\u003c\/td\u003e\n\n\u003ctd\u003eQ-20C054\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003ePower\u003c\/td\u003e\n\n\u003ctd\u003e3W\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eLight color\u003c\/td\u003e\n\n\u003ctd\u003eGreen\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eSupply voltage\u003c\/td\u003e\n\n\u003ctd\u003e3.2V - 3.6V\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eRated current\u003c\/td\u003e\n\n\u003ctd\u003e500 - 700mA\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eLED chip size\u003c\/td\u003e\n\n\u003ctd\u003e7 x 3mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eHeatsink size (star support)\u003c\/td\u003e\n\n\u003ctd\u003e20mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eSupport material\u003c\/td\u003e\n\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eMounting type\u003c\/td\u003e\n\n\u003ctd\u003eStar PCB (MCPCB)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eBrand\u003c\/td\u003e\n\n\u003ctd\u003eOEM\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003ePackage contents\u003c\/td\u003e\n\n\u003ctd\u003e1x 3W green SMD LED chip on aluminum heatsink\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-warranty\"\u003e\n\n\u003ch2\u003eWarranty and support\u003c\/h2\u003e\n\n\u003cp\u003eThe product benefits from a 2-year legal warranty in accordance with current Romanian legislation.
