Advantages of LED Lamps

There are two ways of making a LED (Light Emitting Diode) lamp. One of them is to mix multiple wavelengths of several LEDs to produce white light, allowing the manufacturer to adjust the white light to a specific color temperature, i.e. for home use, a color temperature between 3800°K and 5000°K (the higher the temperature, the more bluish the light; lower temperatures will give a warmer, reddish light).

The second method, use LEDs with a Indium Gallium-Nitride (InGaN) compound and a phosphor layer to create white light. This is the most used method to manufacture white LEDs.

There are LED factories, like the dutch Philips, that manufacture lamps covering a wide spectrum, between 2700°K and 10000°K. Lets remember that the midday sunlight has a color temperature between 5600°K and 6000°K.

LEDs are solid state electronic devices and they’re widely used in virtually every electronic gadget, radio, recorder, computer, and a multitude of daily-use appliances where you can see those bright dots, indicating that a device is switched on.

A LED transform electricity directly into light of one color. Thus, there are red, green, blue, yellow-colored LEDs and more. LEDs do not spend energy in the form of heat that does not produce light because they employ a cold light generation technology. Comparatively, an incandescent light bulb emits in the infrared band (not visible) a large portion of energy that produces. As a result, incandescent light bulbs produce a large amount of heat that is a waste of energy. Besides producing cold light, LEDs:

• Can be powered from batteries or even solar panels.
• Can be integrated into a control system.
• Are small in size and shock-resistant.
• Have a very fast start time ( 60 nanoseconds versus 10 milliseconds for incandescent light bulbs, 1 second or more for fluorescent lights).
• Have an excellent color rendering and they have little or no danger of electric shock because they work in the range of 5 to 12 volts DC.
