Review
‘Light-Emitting Diodes is an excellent examination of the physics and technology of semiconductor LEDs. The narration is simple and direct, and the book is well referenced for those seeking a deeper understanding of the topic.’ Physics Today
Book Description
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.

LED Traffic Lights
LEDtronics® announces 12-inch (300mm) Type 1 and Type 2 TrafficLED™ direct incandescent replacement lamps designed to accommodate pre-existing traffic signal enclosures. Using Indium Gallium Aluminum Phosphide (InGaAlP) and Indium Gallium Nitride (InGaN) Light Emitting Diode (LED) technology, LEDtronics TrafficLEDs emit dazzling light through an optically optimized lens that disperses light uniformly across the entire face of the lamp. LEDtronics Type 1 and Type 2 Red and Green 12-inch LED traffic lamps meet ITE specifications and have Caltrans approval. Type 1 lamps require modifications (i.e., hard wiring the lamp) to retrofit existing traffic housings. Type 2 lamps feature male 25mm Edison bases that simply screw into a socket.
With power draws of just 10 Watts - 12 Watts, TrafficLEDs saves 80% - 90% of energy costs compared to an equivalent incandescent lamp. Such enormous energy savings alone repay the capital outlay in less than three years! The savings don't end with energy consumption. LED signals last much longer than incandescent signals, reduce relamping and routine maintenance, and lower liability costs for municipalities, cities and highway departments. Estimated energy savings for an eight-light intersection per year is between $500 - $550 based on $0.08 per kilowatt-hour. Multiply that figures by the thousands of signal-controlled intersections in the average city. The results? TrafficLED lamps save millions of dollars a year when compared to an equivalent incandescent lamp.
Reduced maintenance outlays are important factors to consider when evaluating the financial aspects of installing LED traffic lamps. With an average life span of 100,000-plus hours (11 years), TrafficLEDs operate reliably year after year. TrafficLEDs perform well in applications subjects to voltage dips or surges. Integrated current-limited resistors and polarity-protection diodes assure that no circuit modifications are required. With the use of multiple LEDs, a TrafficLED lamp continues to provide light even if one or more emitters fail unlike when the filament breaks in an incandescent bulb.
Additionally, since LEDs emit colored light, TrafficLEDs lower concerns surrounding broken or faded colored lenses or filters, which are necessary with incandescent traffic bulbs. (Color produced by an LED is determined by the composition of the semiconductor material comprising the diode chip.) Intensity and color remain virtually stable over lamp's lifetime. Solid-state design renders LEDs impervious to electrical and mechanical shock, vibration, frequent switching and environmental extremes. A molded polycarbonate, UV-resistant lens and a rubber o-ring protect the LED plate from environmental stresses.
Founded in 1983, LEDtronics® leads where others only follow when it comes to designing, manufacturing and packaging state-of-the-art LEDs to meet the world's constantly changing lighting needs. Our inventive product line encompasses an array of direct incandescent lamp replacement Based LED Lamps, low-cost snap-in and relampable Panel Mount LED Lamps, high intensity sunlight-visible Discrete LEDs, PCB LEDs circuit board status indicators, surface mount diodes SMT LEDs, full-spectrum rainbow RGB LEDs and Infra-Red (IR) LEDs.
Prices for TrafficLEDs range from $75.60 - $185.85 each in quantities of 250 depending on LED technology. Available are sunlight-visible Green (10,000mcd), Yellow (7,000mcd), and Red (3,500mcd). TrafficLEDs carry a 3-year limited warranty. Samples are available for qualified customers.
