How can you produce white LEDs?
What will be an ideal response?
One of the great advancements in LED technology was the development of white LEDs. There are two primary ways of producing white LEDs. One employs the use of three individual LEDs that emit the primary colors of red, green, and blue (RGB). The most common method employs a blue and ultraviolet LED with a yellow phosphor coating, much like the coating on fluorescent lights. The phosphor coating changes the monochromatic light produced by the blue/UV LED into a broad-spectrum white light.
