The Different Characteristics Of LED Light Bulbs
Since the compact florescent light bulb has started to rapidly replace the aging incandescent light bulb lately, a new type of bulb is emerging that will replace them both. The light emitting diode (LED) bulb has benefits that make it a better technology.
While the incandescent bulb produces light inside a vacuum and the compact florescent bulb does so inside a tube, the LED is referred to as solid-state lighting. It is solid state since it makes use of solid matter, a semiconductor, to produce light.
The semiconductor consists of both a positively and negatively charged component. The positive layer has small openings for the free electrons coming from the negative part to move through. When an electric charge is applied to the semiconductor, a flow of excited electrons passing through the holes emits a light.
The 2 excellent benefits of LED light bulbs are their long life and energy efficiency. They just use almost one tenth as much electrical energy as normal bulbs and therefore offer big financial savings in power costs and a reduced carbon footprint. This makes them both cost efficient and eco friendly.
Their solid state structure and very low heat emissions give them a much longer lifespan. LED light bulbs drastically outlast even compact florescent bulbs and can easily last for a decade or longer in regular use. This not only saves on the cost of the bulb, but it also saves time and replacement costs. Better suited to survive rough handling and outside conditions, a LED light bulb can be relied on to work when needed most.
Since they attain their full brightness almost instantly and are actually mercury free, LEDs clear up a couple of major issues that compact fluorescent bulbs have (mercury content as well as lag time in reaching full brightness).
LED light bulbs are built to emit a very directional light so the light could be aimed exactly where it is needed. Additionally, their light is nearer to the color of daylight, which research indicate helps people stay alert.
Till recent changes in the technology, the structure of the LED induced a lot of the light to be trapped inside. This in addition to the bluish light they typically emitted brought on a dimmer light that made LEDs unsightly for home usage.
LEDs are now a lot brighter though and can emit exactly the same soft, white light regular bulbs do.
One disadvantage with LEDs that has not been corrected yet is cost. While their power savings and very long life mean LEDs are cost-effective and save money in the long run, they're unlikely to achieve mass consumer acceptance until their costs come more in step with other types of bulbs. Although their costs are coming down, LED light bulbs are still comparatively costly.
Once their prices come down more, LEDs are more likely to become the standard and dominate lighting unless a better technology appears.
