LED stands for Light Emitting Diode, which means led. It consists of a light conduction technology, from electric power.

The LED has the function of sending light in places and tools, lamps, lanterns, etc.


The LED is a conductor of electricity, which when energized, emits light visible to the naked eye. The system of lighting with incandescent lamps, however, uses a metallic filament model and discharge of gases to produce light.

The LED is widely used in electronic products (check this link for more), like flag of warnings, but also in larger instruments, such as traffic lights, as well as panels and curtains of light for outdoors, for example.

Technology and LED lighting is present on several occasions from everyday life. Currently, this system is very common and more economical than old models of lighting, such as halogen lamps, for example.


Currently, it is also common to apply LED technology in televisions.

The LED TV has a liquid crystal light filtering better, compared with the other, that is, the colors that appear in the image are more pure.

Another advantage is the quality of light emitted because it stays the same throughout time, without losing the brightness or change color at any time.
