All About LED Lighting
Those light emitting diodes better known as LEDs are actually 90% more efficient at producing light than the incandescent light bulbs. How do they do that? LED lighting works by passing an electrical current through a microchip. As the current passes through the microchip, it illuminates the tiny LED light producing a visible light. Performance issues of the LEDs lighting are prevented by the absorption of its heat into a heat sink.
Unlike compact fluorescent or incandescent lights, the LEDs don’t “burn out”. They simply experience “lumen depreciation” by their brightness slowly diming over time. Therefore, the lifetime of the LED lighting is based on a prediction of when the output of light will decrease by 30 percent.
You now know how LED lights work, but how are they currently used best?
Top 5 Uses of LED Lighting
#1: Every Day Uses in the Home
You can find many LED bulbs in various different shapes including recessed lighting as well as watt/lumens that have been converted for every day uses. If a bulb that has been screwed into a normal light fixture such as a lamp burns out, you can replace it with a LED bulb. Since specialty bulbs such as those in appliances have equivalent LED bulbs, they can be replaced by a LED bulb. LED bulbs can also replace traditional bulbs in floodlights that light porches, driveways, patios, decks and backyards.
Both desk lights and reading lamps’ traditional bulbs in a home office can be replaced with LED lighting giving better visibility. Old-style bulbs in lights under your kitchen cabinets and recessed lighting can also be replaced with LED bulbs that will provide more light.
The advantage of the LED bulb is that it uses 13% to 15% of the electricity that a standard light bulb uses. Standard bulbs may last hundreds of hours, but the lifespan of a LED bulb even in recessed lighting is tens of thousands of hours.
Since LED Christmas lights are lightweight, small and last so much longer than the standard bulbs, you certainly won’t regret using the LED ones. They use so much less electricity than the standard bulbs. You can pack them away for next year, and they will work in another year. For holiday lighting, there’s none better than LED lighting.
#2: Workplace Lighting
The Harvard School of Medicine conducted a study to determine whether there were benefits of using LED lighting in the workplace. The results of the study showed that workers were more alert, exhibited better performance, had a mood that was more positive, were better able to concentrate and were less fatigued at the end of the work day when they were exposed to LED blue-enriched white light. LED recessed lighting is especially soothing at the workplace.
New and improved LED lights in the workplace had several benefits as well. Both the safety and the productivity of workers were improved by the use of LED lights that were arranged in numerous ways including recessed lighting such as with the use of retrofitted, existing or new fixtures.
#3: Community Places
LED lights often replace public space lighting and street lights. This allows local governments to save costs of lighting public places. Besides the cost savings, the LED lighting is brighter than the outmoded lighting that is much safer as well. Communities that are using LED lighting for their streets, parks, parking lots and other public locations are benefiting by major savings as well as a huge reduction in crime. Happier neighborhoods are created by the use of LED lighting for sports fields, community parks and schools.
The LED flashlights use the same size battery as the conventional incandescent flashlights, but they last far longer. There actually are LED flashlights that can be charged by hand cranking and no longer need batteries at all. The LED flashlights can endure shocks and vibrations that would destroy the old style flashlights by shattering them. A final thought about LED flashlights is that they will, without a doubt, last a lifetime.
#5: Automobile Lights
More and more car manufacturers are now using LEDs light for both the interior and outside lights of the cars. The Audi is actually using LEDs for the running head lights during daytime.
When comparing the LED bulb to the incandescent bulb, the LED takes only milliseconds to respond whereas the incandescent bulb takes several tenths of a second to illuminate fully. It may seem that a few tenths of a second isn’t very significant, but when travelling at highway speed you will travel ten to forty feet before the brake light lights up. Therefore, LED brake lights are much safer
since they warn drivers to stop sooner making rear end collisions less likely.
