Red and Near Infrared Microcavity LightEmitting Diodes $196.21 Lighting is essential to modern society but it accounts for nearly 20 of the electrical energy usage. Thus efforts to increase the conversion efficiencies of light sources are attracting more and more attention. Potential high efficiency light sources are fluorescent lamps or lightemitting diodes (LEDs). Modern LEDs show internal quantum efficiencies of virtually 100 . However, in the case of standard LEDs most of this light is trapped inside the device because of total internal reflection at the interface semiconductorair. Several methods have been developed in order to increase the extraction efficiency. This can be done either by optimizing the device geometry in order to increase the escape cone or by incorporating a resonant structure in order to force the internal emission into the existing escape cone. The latter approach is called microcavity LED (MCLED) or resonant cavity LED (RCLED) and is presented in detail in this work. Novel concepts to further increase the external quantum efficiency are discussed and experimental results are presented.

The Diodes $93.99 High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).

Light-Emitting Diodes (Hardcover) $186.1 Revised and fully up-dated, the second edition of this graduate textbook offers a comprehensive explanation of the technology and physics of LEDs such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III-V semiconductors. Elementary properties such as electrical and optical characteristics are reviewed, followed by the analysis of advanced device structures. With nine additional chapters, the treatment of LEDs has been vastly expanded, including new material on device packaging, reflectors, UV LEDs, III-V nitride materials, solid-state sources for illumination applications, and junction temperature. Radiative and non-radiative recombination dynamics, methods for improving light extraction, high-efficiency and high-power device designs, white-light emitters with wavelength-converting phosphor materials, optical reflectors, and spontaneous recombination in resonant-cavity structures are discussed in detail. With exercises, solutions, and illustrative examples, this textbook will be of interest to scientists and engineers working on LEDs and graduate students in electrical engineering, applied physics, and materials science.

Electronic Circuit $82.85 High Quality Content by WIKIPEDIA articles An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electrical current can flow. The combination of components and wires allows various simple and complex operations to be performed: signals can be amplified, computations can be performed, and data can be moved from one place to another. Circuits can be constructed of discrete components connected by individual pieces of wire, but today it is much more common to create interconnections by photolithographic techniques on a laminated substrate (a printed circuit board or PCB) and solder the components to these interconnections to create a finished circuit. In an Integrated Circuit or IC, the components and interconnections are formed on the same substrate, typically a semiconductor such as silicon or (less commonly) gallium arsenide.

11 Ways to Save Energy and Money by Switching to LED Lighting

Light-emitting diodes (LEDs) are becoming far more common for indoor lighting solutions due to their human and environmental safety, cost, and longevity. An LED is a solid-state semiconductor diode that emits light when an electrical current is applied in the forward direction of the device, as in the simple LED circuit. The effect is a form of electro-luminescence where incoherent and narrow-spectrum light is emitted.

LEDs are widely used as indicator lights on electronic devices and increasingly in higher power applications such as flashlights and area lighting. An LED is usually a small area light source, often with optics added to the chip to shape its radiation pattern and assist in reflection. The color of the emitted light depends on the composition and condition of the semi-conducting material used, and can be infrared, visible, or ultraviolet.

Why Choose LED Lighting?

1. The LED advantage: LED (light emitting diodes) are solid state technology and offers the most efficient (energy savings) form of lighting available. In comparison to conventional incandescent light bulbs, LEDs can be equated at approximately 7 to 8 time equivalence. For example, a 3 watt LED can produce as much illumination as a 20 watt incandescent light bulb.

2. On average, LEDs last 3 to 5 times longer than fluorescents and 20 to 30 times longer than incandescent.

3. LED lamps allow less maintenance costs, lower heating and utility costs and reduces the need for higher rated cable, transformers and electrical components.

4. LED lamps are very resilient, shock and vibration proof and virtually waterproof.

5. LEDs are smaller and more compact and provide more light output per square inch than any other light source.

6. LED lamps produce very little heat and no UV rays, making them safer to handle and safer to use. Ideal for sensitive fabrics/paintings.

7. LEDs are not sensitive to extreme temperatures (unlike fluorescent).

8. Solid state LEDs can be controlled with a processor to achieve unique lighting effects.

9. LEDs are available in cool white, warm white and multiple colors.

10. LEDs draw (on average) about 1/10th the power of today's conventional lighting, providing new alternative solutions to conventional energy saving lamps. LEDs are the most environmentally friendly lamp technology.

11. Along with Fluorescent bulbs, LED technology is the future of lighting. It can reduce many types of pollution and meet the need for the continued world wide energy demand

Summary on Savings: Energy bills, Heating Bills, Fixture Longevity, Maintenance and Replacement Labor. These savings may far outweigh the higher cost of solid state (LED) lighting products.
