Last summer, the scientists field-tested 196 prototypes with the help of children who attended a Danish-run summer school in Zambia. The results showed that some of the lamps had problems due to excessive flexing and light quality degrading after 10 to 20 minutes, which the scientists are fixing by repositioning the solar cells and adding circuitry to deliver power to the LEDs at a constant current. The researchers plan to test improved versions of the lamps in Mali and Malawi.
This investment enables us to expand our presence in China and demonstrates our commitment to serving the growing demands of both our local and global LED customers,” said Chuck Swoboda, Cree chairman and CEO. “We are building on a solid foundation in Huizhou with a strong local management team and a history of manufacturing excellence. We look forward to continued success in China as we drive the led high bay light revolution.”
More than half of Cree’s employees work in China, mostly at the current Huizhou factory. Cree recognizes the support of Party Secretary YeBin Huang and Mayor RuQiu Li during the site selection process.

After being encapsulated in a second sheet of film
Residents have been asked by the city to give their opinion on PolyBrite’s Borealis LED street lighting by contacting the City of Naperville Public Works Department through January 2010. PolyBrite anticipates that continued savings projections will be achieved during this six-month demonstration.
Scientists at the Risø National Laboratory for Sustainable Energy in Denmark have developed an inexpensive way to integrate solar cells, LEDs, and ultrathin lithium batteries to create a lamp that can produce reading-quality light. The lamp's polymer solar cells and circuitry are printed onto large flexible plastic films, and the LEDs, flat batteries, and diodes are mounted using silver epoxy. After being encapsulated in a second sheet of film, the sheets are rolled up and snapped together at the corners with metal fasteners.
Large modules of organic photovoltaics, however, capture just 1 to 2 percent of the photon energy that hits them. But the scientist said even that measly return adds value in the price-sensitive context of rural lighting. In rural areas of Africa, Asia, and Latin America, the average household spends $40-$80 per year for kerosene lamps, and even the cheapest led high bay light devices on the market today cost about a year's worth of kerosene. The total cost of the Denmark scientists' solar-LED lamps is only about $27, and they think they can manufacture an improved version for about $10.

the photovoltaic LED outdoor lighting system
By leveraging the intellectual properties and technical expertise of its membership, the MSSLA intends to promote environmentally friendly lighting options in the state and to advance the companies it represents.
Mechanical Shock standard establishes uniform methods, controls, and procedures for characterizing and screening microelectronic devices suitable for use within government and aerospace electronic systems. This includes basic environmental tests to determine resistance to the effects of natural elements and conditions surrounding government and space operations. The shock test is intended to determine the suitability of the devices for use in electronic equipment which may be subjected to severe shocks as a result of suddenly applied forces or abrupt changes in motion.
The OptoCooler HV14 module is a high voltage and high heat pumping thermoelectric device that is designed to operate at standard electrical power requirements. At 85°C, the HV14 operates at a maximum voltage of 2.7V and can pump 1.5 watts of heat in a footprint of only 3mm2. The module can create a maximum temperature differential (ΔT) of up to 60°C between its hot and cold sides with a zero heat load, making it ideally suited for the cooling and temperature control of optoelectronic devices such as laser diodes, avalanche photodiodes and led high bay light.
The mission was to examine system performance, photometric performance, energy savings, and whether people accepted the photovoltaic (PV) LED outdoor lighting system. The Field Test DELTA: Post-Top Photovoltaic Pathway Luminaire evaluated 24 prototype Renaissance luminaires designed by Sullivan Renaissance, Philips Hadco and SolarOne? Solutions. The Renaissance is a post-top luminaire with a decorative, traditional-style appearance that operates LED modules powered by photovoltaic (PV) panels. The luminaires were installed at three sites in Swan Lake Park, the Village of Woodridge, and Bethel Woods, site of the 1969 Woodstock concert festival.

how LED technology will add value to many types of light installations
The OLED technology has several advantages over that of conventional lighting. Such systems can be used in television screens, computer monitors, small, portable system screens, advertising, information and indication, as well as in light sources for general space illumination, and large-area light-emitting elements. After many years of development,led high bay light has now started commercial production. According to research organization, the market is expected to be worth over $6 billion by 2018.
"This breakthrough is going to change the day-to-day business of every single lighting designer in the world. Lighting designers who get their business ready now will be the ones who see the lion's share of the profits, " said OLED Insider's spokesperson Joshua Bull.
The OLED Lighting Design Summit, for which 16 LED industry experts have been confirmed so far, will see discussion over some of the pertinent issues. The Summit will also provide an exclusive insight into how LED technology will add value to many types of light installations and broaden design capabilities through improved colour range, viewing angles etc.
Opto Semiconductors announced it has developed new transparent OLED prototypes which are only a few hundred micrometers thick and do not need separate encapsulation. The samples have a luminous area of 210 cm² and are already showing the enormous potential of OLED light sources.
The test samples were developed as part of the TOPAS research project funded by the Germany Ministry for Education and Research (BMBF). The aim of the project is to produce 1 m² large transparent OLED modules and will run until 2011.

This LED is stocked in black and white
The Directors of the Fraunhofer IPMS, Prof. Hubert Lakner and Prof. Karl Leo, have hailed the foundation of Ledon OLED as a major milestone on the road to a European OLED industry: "Merging the manufacturing expertise of the Fraunhofer IPMS with the experience of a leading provider of professional lighting solutions like the Zumtobel Group will greatly accelerate the market launch of high quality OLEDs for lighting applications and provide key impetus for the ongoing development of this technology of the future.”
This LED light runs on input voltages ranging from 9 volts to 50 volts DC and its IP68 rating makes it applicable for wet area and dry area applications alike. Equipped with a stainless steel mounting that enables the operator freedom to position the light beam angle, the mounting itself is reinforced with 6 rubber shock isolators to protect the light and stabilize the beam in extreme vibratory conditions. Built and tested in the mining industry, the led high bay light can be configured for a long range spot beam reaching 3500 feet or a wide area flood beam covering an area 2500 feet long and 190 feet wide. This LED is stocked in black and white, but other colors, including desert tan are available. The LED10W-9S is Buy American Compliant.
“The LED10W-9S LED generates 7200 lumens of light while only taking up about an area the size of a 5.5 inch cube,” said Rob Bresnahan. “This is where we are heading with a lot of our low voltage vehicle, boat and heavy equipment lighting. These light rival our 50 watt HID in overall spot beam length and definitely outperform those HID lights when it comes to wide area lighting. With no bulbs to change and 50,000 life hours, these rugged lights will serve our commercial, industrial and military customers well. We have taken everything we have learned for our other LED lights and integrated into these newer fixtures.
