LED & CFL Briefing: PSE&G, Kimball, Jo-Ann Fabrics
Jo-Ann Fabric and Craft Stores has retrofitted the 777,350 square foot parking lot at its Hudson, Ohio, headquarters and store with GE Lightingâ€™s Evolve LED Series Area Lights. The new system is achieving energy savings of 80 percent, and it is projected to reduce Jo-Ann’s annual power use by 200,000 kWh, the company reports.
The facility replaced 52 HID lighting systems on 35 poles. The LED system generates less light than the HID units, but the advanced optics of the LED luminaire directs its light more efficiently, the company said.
US Lighting Tech (USLT), a manufacturer of induction lighting, has completed delivery of more than 110,000 of its Jersey Series Cobra head induction street lights to Public Service Electric and Gas Company (PSE&G), New Jerseyâ€™s largest electric and gas utility. The installation project is part of PSE&Gâ€™s Green Street Lighting Initiative. The project is estimated to save 40 percent on energy costs per fixture with total savings of 45,000 MWh annually, and it cuts CO2 emissions by 21,000 tons per year, according to USLT.
Jasper, Ind.-based hangar and flight operations offices of Kimball International completed a lighting installations project that the company said will save more than 10,000 kWh of electricity per year and reduce utility costs by approximately $1,200 dollars a year. Kimball replaced Metal Halide and T12 Fluorescent light fixtures with more energy efficient T5 and T8 fluorescent fixtures, along with occupancy sensor light switches. The project earned Kimball an incentive rebate from the Indiana Municipal Power Agency (IMPA), the company reported.
Lighting Science Group, an LED lighting company and producer of Energy Star-qualified bulbs, has hit a manufacturing milestone with the production of 1 million LED bulbs in the first quarter of the year at its Satellite Beach, Fla., facility. The company said it achieved the one-million mark in 2010, but only by the second half of the year. It lists as its major clients and projects the International Space Station, the Times Square Ball, retail chains Yankee Candle and Starbucks, and the cities of Dallas, Washington, D.C., and Salt Lake City.
Australiaâ€™s RMIT University has developed a commercial hybrid solar lighting technology as part of the City of Melbourneâ€™s 1200 Buildings energy efficiency program. The system tracks the sun and uses a fiber-optic cable to concentrate solar energy to areas that have no direct access to sunlight. The technology delivers energy savings of 50 to 75 percent, reports the International Business Times.
Collectors move to focus the sunlight onto 127 optical fibres, which are conducted into a single chord. The bendable optical fibres can be joined to hybrid light fixtures connected to diffusing rods that disperse the light. According to the article, one rooftop collector can power up to eight hybrid light fixtures capable of lighting an area of about 100 square meters.
Outdoor lighting systems at the recent Lightfair were featured in a report by LEDs Magazine. Eye Lighting showed its new KiaroLED luminaire. The product family uses the Luminus SST-90 LED, which has a package size of 10×11 mm, but with an emitter diameter of around 3 mm. Eye Lighting offers a choice of Type II, III, IV, and V Illuminating Engineering Society of North America (IESNA) beam patterns, but uses a new TIR lens to form the beam pattern. Eye Lighting worked with an undisclosed optical specialist to develop a total internal reflection (TIR) lens for each of the 4 patterns, according to the article.
Bridgelux demonstrated array-based LED area lights from SimplyLEDs. SimplyLEDs makes acorn-style LED lighting, available as retrofit kits and finished products. The Anello family can create Type III and IV beam patterns. The acorn style light eliminates the need for a TIR or other optics. Instead, the Anello design uses nine Bridgelux arrays, each with 12 emitters that radiate light outwards. A reflector helps spread light downward, the article said.
LEDs Magazine also covered the LED-based Roadmaster street light from the Lighting Science Group (LSG), saying that their product could lower the cost of entry for deploying LED lighting outdoors. The design has integrated the driver onto the printed-circuit board, and it doesn’t have an electrolytic capacitor on the output – the most common failure point in most drivers – thus reducing costs, the article said.
