Light-emitting diode ways of producing white light-emitting diodes (WLEDs), LEDs that generate high-intensity white light. One is to use individual LEDs that emit three primary colors—red, green, and blue—and then mix all the colors to form white light. The other is to use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light, much in the same way a fluorescent light bulb works. The 'whiteness' of the light produced is essentially engineered to suit the human eye. The yellow phosphor in LEDs is cerium-doped YAG crystal, in powder form and may be suspended in plastic,
SMD LED Module 5630 SMD LED Module and the SMD 5730 LED Module. The brightness may vary depending on the driving current, inversely affecting the device's lifespan. SMD LED modules are widely used, in LED lamps, for backlighting, home illumination, shop-windows, advertising, automobile interior lighting, Christmas lights, and numerous lighting applications. SMD LED Module An SMD LED Module (surface-mount device light-emitting diode module) is a type of LED module that uses surface-mount technology (SMT) to mount LED chips on printed circuit boards (PCB). It is a self-contained surface-mount LED device designed either to function on its own or to plug into a compatible
