Although
fluorescent lamps or the more popular Compact Fluorescent Light (CFL)
bulbs was replace the most important election in recent years to
incandescent lamps are LED (Light Emitting Diode) lamps now rapidly
gaining attention in the field of environmentally friendly and energy
efficient lighting.
But how exactly does an LED bulb work and how she wins hype in the market today? Let us begin with a brief history.
But how exactly does an LED bulb work and how she wins hype in the market today? Let us begin with a brief history.
The establishment of the LED can be as far back as 1907, a British experimenter HJ Round of Marconi Labs named as discovered the phenomenon known as electroluminescence traced. Further research and development has been made by a number of people, until finally in 1962 developed Nick Holonyak, Jr., the first practical visible spectrum LED.
He was then regarded as the father of the LED. The first LEDs emit only red light. However, further research and development allows us to LED lamps produce almost all of the light spectrum. It was then off a simple indicator light to a multi-purpose light and electronic tool. We
can now see them in a number of different colors for a number of
different purposes of televisions, flashlights, light bulbs and many
other electronic devices.
Now that we know his story, let us look how this light works. A diode is the simplest type of semiconductor device, and generally speaking, a semiconductor is a type of material that has the ability to perform electrical client. It's just that different semiconductors have different abilities in performing this task.
Normally a diode is only allowed to move in a flow direction, but in the case of the LED flows in two directions. It can go electrical current through a negative charged to a positively charged anode and cathode. This process allows the electrons through the electron-hole in the device, which then recombine an energy known as photons. Photons pass through the action of light known as electroluminescence.
How does the LED light produce different colors? It is a function of the energy of the photons, which is determined by the band gap of the semiconductor is produced. LED lamps have a very long life due to the fact that there is no filament light bulbs used in contrast to the proven and safe, since they do not contain harmful substances such as mercury found in fluorescent tubes.
This technology is used in the creation of the LED light bulb. The LED lamp is a solid-state type of lamp that uses LED as the light source. We know for a fact that a single light bulb is not enough to illuminate an area, but the combination of a number of them proved to be very effective.
This light produces less heat and uses less energy than incandescent bulbs and even energy-saving lamps. These are just some of the reasons why this is fast becoming the choice if you. Provide energy-saving lighting Not to mention his long life along with his health and environmental protection security features....
