The Workings And Features Of LED Light Bulbs

Since the compact florescent light bulb has started to quickly replace the aging incandescent light bulb lately, another sort of bulb is emerging that may replace them both. The light emitting diode (LED) bulb has benefits that make it a superior technology.

While the incandescent bulb creates light in a vacuum and the compact florescent bulb does so in a tube, the LED is referred to as solid-state lighting. It's solid state because it uses solid matter, a semiconductor, to generate light.

The semiconductor consists of 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 circulation of excited electrons passing through the holes emits a light.

The two excellent advantages of LED light bulbs are their really long life and energy efficiency. They only use around one tenth as much electricity as traditional bulbs and thus offer big financial savings in power expenses and a reduced carbon footprint. This makes them both cost efficient and environmentally friendly.

Their solid state structure and 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 additionally saves time and replacement costs. Better suited to survive rough handling and outdoor conditions, a LED light bulb could be relied on to work when required most.

Since they attain their full brightness nearly instantly and are mercury free, LEDs clear up 2 main problems that compact fluorescent bulbs have (mercury content and lag time in reaching total brightness).

LED light bulbs are built to emit an extremely directional light so the light can be aimed exactly where it's needed. Also, their light is nearer to the color of daylight, which research indicate helps people stay alert.

Until recent changes in the technology, the construction of the LED caused a lot of the light to be trapped inside. This in addition to the bluish light they typically emitted brought about a dimmer light that made LEDs unattractive for home use.

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

One drawback with LEDs that has not been corrected yet is cost. While their energy savings and 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 costs come more in line with other sorts of bulbs. Although their costs are coming down, LED light bulbs are still comparatively expensive.

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