Streetlamp Retrofits Are Lighting Up the LED Market

LA-street-lamp-energy-manageThe LED retrofit market is at the beginning of a huge upward swing, according to an article in Forbes. IHS Technology reports that of the 140 million streetlights installed worldwide, just over 13 percent are LEDs, and that percentage is expected to jump to almost 65 percent by 2020.

Although LEDs cost three to four times more than traditional streetlamps, they last three to four times longer and produce two to three times more light per watt. They also deliver 30 percent to 70 percent in annual electricity savings over their predecessors, are more programmable and are easier to connect to citywide wireless networks. Continue reading

Shift In Lighting Technologies to Dim Energy Use By End of Decade, says IHS

A fundamental paradigm shift in lighting technologies toward more efficient lamps and bulbs will significantly reduce global electricity demand for general illumination in the next few years, according to IHS.

The energy usage of the installed base of lighting technologies for general illumination will fall to a projected 2.75 trillion kilowatt-hours (kWh) by 2020, down 24% from 3.61 trillion kWh in 2013. Overall, the installed base for general lighting-which covers homes, businesses and street lamps but not architectural or theatrical lighting-will account for 10.3% of the net electricity generated in 2020, down from 16.4% in 2013.

Part Two: Daylight Harvesting, Other Dimming Strategies Help Lower Energy Costs

Daylight is free, and many spaces inside buildings are daylit, yet electric lighting is left on unnecessarily. Daylight harvesting harnesses this free, natural light, using such building control system strategies as light sensing, occupancy sensing, and shade control, while automatically adjusting the energy use of HVAC and electric lighting systems.

The results? Reduced overall energy costs, coupled with healthy and productive working environments. Daylight harvesting technologies include photocells, occupancy sensors and centralized or distributed control systems. The strategy can be implemented during building design and planning or even retrofitted flexibly at a later time. Continue reading

Wembley Arena Shows How LEDs Change the Emergency Lighting Landscape

Emergency LED lighting from GDS and its ArcSystem can become a functional and integral part of the house lighting system in public venues such as the Wembley Arena in London.

wembley_lighting080613GDS (Global Design Solutions) has announced that the famed Wembley Arena in London now relies on 44 Arc eight-cell LED fixtures for emergency lighting. But the efficiency and functionality of solid-state lighting (SSL) will allow the arena to utilize the emergency lighting as a functional cog in the overall house lighting. Continue reading
