Unlike conventional incandescent lamps which need to convert the electricity into thermal energy first and then to light, LED illumination is achieved when a semiconductor crystal is activated so that it directly produces visible light in a desired wavelength range. With the continuous development of lighting technologies, more possible future applications of LEDs will be seen. Advantages and disadvantages of using LEDs are to be discussed as follows.
