Light-emitting diode superior for illumination in terms of color rendering, whereas one cannot appreciate the color of red or green objects illuminated only by the yellow (and remaining blue) wavelengths from the YAG phosphor. The first white LEDs were expensive and inefficient. However, the light output of LEDs has increased exponentially, with a doubling occurring approximately every 36 months since the 1960s (similar to Moore's law). The latest research and development has been propagated by Japanese manufacturers such as Panasonic, Nichia, etc. and later by Korean and Chinese factories and investment such as: Samsung, Solstice, Kingsun, and countless others. This trend is
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
