The Different Characteristics Of LED Light Bulbs

Since the compact florescent light bulb has began to quickly replace the aging incandescent light bulb lately, a brand 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.

Whereas the incandescent bulb generates 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 as it makes use of solid matter, a semiconductor, to produce light.

The semiconductor is made with both a positively and negatively charged component. The positive layer has little openings for the free electrons from the negative component to cross 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 only utilize about one tenth as much electricity as traditional bulbs and thus offer big savings in power expenses and a decreased carbon footprint. This makes them both cost efficient and eco friendly.

Their solid state construction and really low heat emissions give them a longer lifespan. LED light bulbs greatly outlive even compact florescent bulbs and could easily last for a decade or much longer in normal 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 outdoor conditions, a LED light bulb can be relied on to work when required most.

Since they reach their full brightness nearly instantly and are actually mercury free, LEDs clear up 2 main issues that compact fluorescent bulbs have (mercury content as well as lag time in reaching full brightness).

LED light bulbs are meant to emit a very directional light so the light may be aimed precisely where it's required. Also, their light is closer to the colour of daylight, which research indicate helps people keep alert.

Until recent changes in the technology, the structure of the LED caused a lot of the light to be trapped inside. This and the bluish light they often emitted brought on a dimmer light that made LEDs unpleasant for home usage.

LEDs are now much brighter though and could emit exactly the same soft, white light regular bulbs do.

One disadvantage with LEDs that has not been rectified yet is cost. While their energy savings and really long life mean LEDs are cost-effective and save money in the long run, they are not likely to achieve mass consumer acceptance until their prices come more in step with other sorts of bulbs. Though their costs are coming down, LED light bulbs are still relatively expensive.

As soon as their prices come down more, LEDs are more likely to become the standard and dominate lighting until a better technology appears.
