Breakthroughs in LED technology boost beam angle Gem Hsin Electronics has made new
advances in research and development of LED lighting products. The firm claims its latest developments enable wider beam angles than its competitors and unparalleled light uniformity. Combined, Gem Hsin’s says these patented design achievements give its latest products a superiority that is unmatched in the LED industry. Gem Hsin has already started incorporating these cutting-edge research breakthroughs into their line of T5 / T8 LED Tube Lights.
T8 LED tube light Gem Hsin’s engineers, with their extensive backgrounds in cooling, have made significant breakthroughs in reducing the size of the heat-sinks needed in their LED products. Using laser-precision technology, extremely small holes are drilled beneath each LED, creating direct paths for heated air to escape to the heat-sink.
This improvement may appear minute but means that LEDs will stay cooler, improving efficiency and lifespan, and at the same time require less heat-sink mass for thermal optimisation. What’s more, this design breakthrough enables Gem Hsin to offer lighting products that have much wider beam angles, up to 220 degrees, as compared to competitors who typically can only offer beam angles of 180 degrees. One of the major criticisms of LED light has been that it is too focused and unpleasant, but

these wider beam angles, provide unmatched natural LED light for home and office environments.
Gem Hsin’s R&D team has also developed a new way to position LEDs into tube lights. Whereas other LED makers use a single row of LEDs in their tube lights, Gem Hsin is now implementing a design that increases uniformity and quality of light by using two, staggered rows of LEDs.
Instead of uneven light with unsightly bright and dark areas, Gem Hsin’s T8 LED Tube Lights produce, along their entire length, exactly the same high-quality, natural, soft light that consumers have been waiting for in an LED tube light. Both of these engineering accomplishments have already been recognised as unique inventions and granted patents in Japan and Taiwan. Furthermore, Gem Hsin has started incorporating them into their line of T5 / T8 LED Tube Lights that use 20% less energy than competing products and are available in two-feet-long, three-feet-long, four-feet-long, and eight-feet-long models, providing users with substantially lower operating costs.
First Solar to provide Alpine Solar project for NRG Energy
NRG Energy and First Solar, have signed an agreement for First Solar to provide engineering, procurement and construction (EPC) services for NRG’s 66-MW (AC) Alpine solar project in Lancaster, California. First Solar will also provide operations and maintenance (O&M) services.
Electricity from the Alpine project will be sold under a 20-year power purchase agreement with Pacific Gas and Electric Company, helping California meet its ambitious renewable energy goals. Construction is expected to start before the end of 2011 and be completed in Q3 2012, creating an estimated 250 jobs over the course of construction. The project will use First Solar’s advanced thin film CdTe photovoltaic (PV) modules.
The electricity generated by Alpine is enough to serve a yearly average of nearly 25,000 homes, and more than double that number at maximum capacity during peak hours of the day. The project is expected to offset approximately 1.5 million metric tonnes of greenhouse gases over 20 years, the equivalent of taking over 15,000 cars off the road annually.

“Less than two years ago, NRG and First Solar began our collaboration for our first solar plant at Blythe, which was the largest solar plant in California at the time. Alpine is three times that size, so we’ve really come a long way together in a short amount of time,” said Tom Doyle, president of NRG’s Solar and West Region.
“First Solar is excited to be working again with NRG,” said Jim Lamon, First Solar Senior Vice President for EPC and O&M. “Our experience developing and building out our 2.7 gigawatt North American pipeline of utility-scale PV projects enables us to get our customers’ projects rapidly completed and connected to the grid.”
