Understanding The LED Module
A light emitting diode (LED) is a semiconductor component that allows current to pass in only one direction. When current is applied, the LED emits light. The module is usually used in creating portable lighting. Some of the applications of the module are: night lights, outdoor lighting, headlamps, flashlights, book lights, and multiple bulb units. In all of these applications the module emits bright light from a very small bulb.
