Light emitting diode, abbreviated as LED, is a semiconductor source of light with a more bright and steady light spectrum compared to other sources. LEDs were originally restricted to single light uses especially as indicator lights on everything from computers to automobiles.
Several electronic companies discovered through as series of researches that when LEDs are grouped together, they emitted a very intensive, bright white light that consumed less power and generated less heat. Since their introduction, LEDs have greatly gained popularity in general lighting and are now most preferred against the traditional incandescent light bulbs. Below are some LED facts to give you a head-start on the bright side of this little electronic invention.
Some facts about Light emitting diodes
LEDs have a relatively very long useful life. Most reports estimates 50, 000 to 100, 000 hours of useful life. Other bulb such fluorescent tubes are rated at about 15,000 to 18,000 hours while incandescent bulbs at 1, 000 to 2,500 hours depending on the condition of use.
LEDs are known to produce less heat and hence consume less power as compared to compact or incandescent bulbs. It is estimated that consumers can save up to 90% on energy costs by replacing existing bulbs with LED bulbs.
LEDs are ideal for use in situations where there is frequent on-off cycling, unlike HID bulbs that require a longer time before restarting or fluorescent lamps that easily fail when cycled often.
Generates minimum heat
As mentioned earlier, LEDs generates very little heat thereby concentrating most of the energy to light. This fact ensures that there is no extra load on conditioning systems, an extra saving on the energy cost. Typically, a 60-watt standard incandescent bulb will generate 175C, a13-watt fluorescent lamp about 140 and as much as 212C for the standard PAR 75-watt bulb. When the above bulbs are replaced with LEDs, heat generated can be reduced up to as little as 27C to 30C.
No electromagnetic interference
The electronic cabling and working mechanism of the LEDs reduces the harmonic noises that are common with fluorescent bulbs. Additionally, they are not prone to electromagnetic interferences as compared to other bulbs.
LEDs can be easily dimmed by either lowering the flowered current or using pulse-width-modulation. This is what makes LED lights ideal for viewing on camera and also used as headlights on cars.
LEDs have proved in many ways to be friendlier to the environment as compared to incandescent or fluorescent bulbs. They do not contain halogen gases, toxic materials or hazardous mercury. They also do not emit infrared or ultraviolet rays, which makes them safe to humans and 100% recyclable.
LEDs, being portable solid-state components, can not be easily damaged by external shock, unlike the fragile fluorescent and incandescent bulbs. They can also work just fine in both hot and cold environments while withstanding frequent on-off cycling.
Easy on the eyes
LEDs produce soft white light without an interfering glare. The light spectrum resembles the natural daylight with an ability to enhance your working area with a bright clear light.
