    Carley Lamps History In 1943 James Carley started working as a lamp apprentice at his uncle’s factory, Chicago Miniature Lamps. After serving in the U.S. Marines, graduating from the University of Illinois and again working for Chicago Miniature Lamps, James Carley started his first company in Los Angeles, California in 1960. James Carley 1960 Lamps Inc. Los Angeles Miniature Products or LAMPS quickly gained a reputation for building high quality miniature lamps exactly to customer specifications. LAMPS’ reputation continued to grow as NASA chose James Carley to build To maintain its technical excellence in the special miniature lamps for the Apollo Space miniature lamps industry and continue to Shot, Voyager Probe and most recently the develop the company, James Carley expanded Space Shuttle. Carley Lamps enjoyed rapid Carley Lamps’ product range and introduced growth and success in the Aerospace industry high intensity miniature lamps to the flashlight in the 1970s & 80s. industry in early 1980. Today, in 1999, professional police, firefighters and special forces prefer and request Carley lamps for their flashlights and weapons mounted illumination systems. Carley Lamps is the largest producer of quality flashlight lamps in the world. In early 1990 Carley Lamps was approached to develop a high intensity medical lamp for a hand held Fiber Optic Laryngoscope. Curtis Carley, Carley Lamps Vice President developed and Craig, James, Curt and Suzy Carley patented the Mediflector® brand medical lamp. 1999 Carley Lamps Inc. The Mediflector® medical lamp incorporates a miniature reflector around a high intensity gas filled lamp. The fiber optic industry has been quick to capitalize on the performance of the Mediflector® and over the past nine years Carley has experienced intense growth in the Medical Illumination field.

  • Final Report for Comprehensive Study on International Practice on Phasing out Energy Inefficient Incandescent Lamps
    Final Report For Comprehensive Study on International Practice on Phasing Out Energy Inefficient Incandescent Lamps Prepared by November 2009 EEExxxeeecccuuutttiiivvveee SSSuuummmmmmaaarrryyy � 1. As part of the Government’s ongoing efforts to promote efficient use and conservation of energy, the Government would like to keep track of the recent worldwide development on phasing out of inefficient incandescent lamps and switching to more energy efficient ones so as to reduce carbon emissions. The Government commissioned Hong Kong Productivity Council (HKPC) to carry out comprehensive fact-finding study to benchmark the overseas practices and the various options adopted in phasing out of energy inefficient incandescent lamps as well as the practices and approaches in the phasing out schemes of these overseas countries; and the availability of viable and efficient alternatives for different categories of incandescent lamps. This report details the findings of the study and provides an overview of the different phasing out schemes developed by various countries. It should be noted that as the phasing out schemes of overseas countries are still evolving, this report provides a snap-shot of the information available at the time the report is prepared. 2. Incandescent lamps are commonly classified in accordance with their functional and technological characteristics. The functional classification for incandescent lamps is based on whether the lumen output is non-directional or directional. They are commonly named as non-reflector type lamps (or called non-directional lamps) and reflector type lamps (or called directional lamps). On the other hand, the technical classification is based on the in-fill gas types of the incandescent lamps and operating voltage of the lamps.

  • 39 Reliability-Oriented Design Natural Design for Heat Sinks Micro- and Nanostructured 3D LED Technologies Safety Regulations &
    www.led-professional.com ISSN 1993-890X Review LpR The leading worldwide authority for LED & OLED lighting technology information Sept/Oct 2013 | Issue 39 Reliability-Oriented Design Natural Design for Heat Sinks Micro- and Nanostructured 3D LED Technologies Safety Regulations & Production Testing EDITORIAL 1 LED Lighting Technologies It isn’t only the general lighting market that is being fundamentally changed by Solid State Lighting technologies; it’s the whole lighting industry. Predictions for the next five to seven years are that we’ll see more LED/OLED performance increases along with continuous price declines. The challenges of phasing out old technologies and ramping up new technologies are huge. Therefore, profitability is key to survival in this volatile environment. “Merging” lighting with the fast and innovative semiconductor industry requires new processes, structures, partners, alliances and a new understanding of the lighting sector itself. Restructuring the lighting business to enable potentials for new, environmentally friendly lighting is required to make a substantial contribution to the world’s energy situation. New and enhanced technologies are still the major innovation drivers in semiconductor lighting. Technologies are being increasingly merged on a sub-system level while diverse industries are intensifying their collaborations. But the key question remains: “What will the winning approaches be in the years to come?” In order to help find the answers, the LED professional Symposium and Exhibition, which takes place in Bregenz, Austria every September, summarizes important success factors in the area of lighting. The LpS 2013 will deliver the latest information about state-of-the-art technology and developments within the entire range of topics that Solid State Lighting encompasses.
