Energy Effectiveness And Effluence Management Make The LED Light Bulb An Attractive Alternative

Jan. 16, 2012 - PRLog -- Light emitting diodes are created through electrical science and chemistry. A semiconductor has a variable capacity to conduct electricity, and there are two types; an N-type has extra electrons, while a P-type has extra positrons. A diode is simple material with an N-type and P-type semiconductor bonded together.

Without something to drive the process, it comes to stasis as positive and negative charges offset creating a depletion zone. To overcome this, electrical power must be applied in the proper direction to ensure continued flow. As they cross the surface they experience a reduction in energy level and radiate photons.

But whether or not we can see them depends on their frequency, which we can manipulate by using different chemical compounds in the semiconductors. By selectively choosing elements, the color emitted can be chosen. This is the basic element, it needs to be made useful.

Once this emission device is created, is encased in plastic for durability and to focus the photons in one direction. By making the covering the correct shape them into photons can be focused to the top increasing in magnitude of the lumens produced. They can be made small enough to easily compatible with circuit boards and can even be used to backlight television screens.

The comparison between incandescent and light emitting diodes shows how much more efficient the latter is. While an incandescent bulb produces 17 lumens per watt of energy, the diodes create 79, over four and one half times more efficient. The material needed to make them was too expensive up until the year 2000, but since then the price has dropped dramatically, making them a viable alternative.

This once again technology has produced a much superior product for our use. Gone are the days of the fragile glass devices that get to hot in use to be removed and replaced by hand. The new product is lighter and tremendously more efficient. An incandescent type will cost $175.00 oer year to run, the diode type costs less than $30.00 per year.

The future will tell how we use these small efficient powerful luminescent sources. They last 50 times longer than incandescent, and six times more than, compact fluorescent types, and have no heavy metal. One might wonder why the older models are still popular, and the answer is price. At $70.00 dollars each, people are not convinced they are the answer; yet.
