LED Lights are the latest technology in energy efficient light.LED stands for light emitting diodes, a semi conductor device that converts electricity into light.
LED is a semi conductor device that emits visible light when an electric current passes throughit.The light is bright, but not in most LED it is monochromatic, occurring at a single wave length. The output from an LED can range from red (at a wavelength of approximately 700nannometers) to a blue violent (about 400 nanometers) some LEDS emit infrared (1R) energy. (830 nanometer or longer)such a device is known as an infrared-emitted diode (ired).
Elements of IRED or LED
It consists of two elements of processed materials called p-type semiconductors and n-type semiconductors. Which are placed in direct contact, forming a region called the P-N junction. The LED or IRED has a transparent package, allowing visible or IR energy to pass through .It also has a large P-N junction are whose shape is tailored to the application.
Benefits of LED
Benefits of LED compared with incandescent &fluorescent illuminating devices. Low power requirement -They can be operated with battery power supplies.Long life -If properly installed they last up to a decade.High efficiency- Most of the power supplied is converted into radiation in the desired form, with minimal heat production.LED lighting is by far the most power saving and smart solution for illumination. It makes a huge leap in technology of digital word unlike the analog as well they are out of the world. They are also ecologically friendly; it contains no toxic materials and are 100%recycable, and will help you reduce your carbon footprint by up to a third. The LED lights are resistant to shock, vibrations and external impacts, they make great outdoor lighting system for rough conditions and exposure to wind, rain or external vandalism, construction or manufacturing sites.

LCD panel backlighting.-Specialized white LED are used in flat panel computer displays.Remote control: Most home –entertainment remotes use IREDs to transmit data to the main unit. Indicator lights -These can be two –state i.e on/off bar graphs or alphabetic-numeric read outs.Fiber optic data transmission- Ease of modulation allows wide communications band with minimal noise, resulting in high speed and accuracy. Opt isolator-Stages in an electronic system can be connected together without unwanted interaction.
Factors to consider when choosing LEDS
Brighter vs.Efficiency; you should know how much you need.Bulb makers measure light output in lumens and put it on the packaging.Know your color temperature –the specific shade of white light each bulb offers.colour temperature is measured on the Kelvin scale.Price and compatibility -Some bulbs will dim more than others to choose the ones that suit your preference while the price has really gone down due to competition. The prices of fixing LED lights its really expensive compared to other lighting but the LED lights are long lasting and can stay up to 20 something years.
LED or IRED spotlights are the best so far and are encouraged widely. See more those site: http://www.larsonelectronics.com/
