L.E.D. stands for light emitting diode. This technique, light is created by a semiconductor diode, the bulb is turned on when forward biased, electrons recombine with holes and energy is released in the form of light. Color of the light can be determined by the semiconductor. With this type of research makes this energy efficient bulbs with longer duration and smaller.LEDs flashlight uses a search and support calls for better police and fire crews in the search for criminals or victims of major disasters.
