LED Lighting - The Future of Energy-Efficient Lighting
LED lighting is being increasingly preferred for a variety of purposes, including home, office illumination, vehicle, landscape and public safety lighting. The LED technology is being increasingly used in flashlights, lanterns, head lamps, and book.These small LED lights have become an integral part of our lifestyle that we have begun to use them without being of it. For example, indicators on appliances such as coffee makers that convey to the users that the appliance is ready to be used are LED lights.
Small lights on cellphones indicating active power are LED lights. LED is an abbreviation for Light Emitting Diode, which is a semiconductor that converts electricity into bright. This do not require a filament as conventional bulbs do to generate bright. LED lights have diodes as their sources of power. Each diode has a diameter of about 1/4 inch and consumes about ten milliamps of current to give out light at about 1/10 of a watt.
These diodes are well-protected by plastic bulbs that contain them. It operate on power generated by the motion of electrons, and emit white bright. Despite their smallness in size, It work wonders when used in combination, for high-intensity applications.
LED lights are available in various efficiency. This for residential purposes are about 20 lumens/watt. However; with latest advancements, LED lights with capacities as much as 160 lumens/watt are also being developed. It is not harsh; they emit soft lights. The less intensity of brightness is due to the usage of sodium lamps of low pressure.
Capabilities of this system are many. One is the unidirectional illumination LED lighting enables. This property of it makes them very useful for various applications where it needs to be focused in a single direction. They are more durable than conventional system bulbs as they are resistant to impact by thermal influences and vibrations.
There are no UV rays or Infrared rays resulting from this system. This makes it ideal for outdoor lighting as UV rays attract bugs. There is no mercury in LEDs; so, it doesn't get hot on usage. This doesn't disrupt radio or TV signals as there is no ballast in a LED system. But it should be noted that LED lights are heat-sensitive; exposure to surplus heat can damage not only the quality of light emitted but also the lifetime of the system.
Owing to its numerous advantages, the application of this system has increased enormously. It can be used for focused lighting in dark interior areas such as cupboards, areas under kitchen cabinets, garage interiors, and overhead. It is extensively used for walkways, art , landscape, reading areas and night.
