| For example, white, green, cyan, blue and royal blue light are emitted with Indium Gallium Nitride (InGaN) solid-state material; red, red-orange and amber light are emitted with Aluminum Indium Gallium Phosphide (AlInGaP) solid-state material.
LEDs are just like conventional light bulbs, but LEDs don't have a filament that will burn out,and they don't get extremely hot nor produce infra-red and ultra-violet(UV). LEDs are illuminated by the movement of electrons in a semiconductor material, and they last much longer than a standard light bulb. |
