LED luminaires market to double in 4 years news on the Electrical news magazine


An Interesting article found on Electrical News Magaize which discusses how the LED market will expand rapidly in the next 4 years:

Strategies Unlimited's LED Luminaires, Market Analysis & Forecast includes nine LED lighting application segments and analysis for the period from 2008 to 2014. According to this forecast, the global market for LED luminaires is expected to grow from $3.8 Billion in 2010 to $8.3 billion by 2014.

UK Made LED Lighting
Rapid improvements in performance and price of commercially available high brightness LED packages, heightened awareness about energy efficiency, phasing out of incandescent bulbs, and fiscal stimulus undertaken by countries around the world, created conditions for adoption of white light application of LED technology, which otherwise would have faced the low-volume-high-cost conundrum.

Quality issues that affected the market penetration of previous energy efficient lighting technologies continue to affect this market but the resolve to reduce energy consumption is likely to propel this technology to be widely commercialized and adopted by the market.

Being the most efficient light source technology for applications requiring a directional beam of light and batteries, consumer portable applications were the largest segment of the LED luminaire market in 2010. The quality of LEDs has improved to a point that performance is no longer an issue. The issue now is the price of designing LEDs into luminaires.

Color and color-changing application in architectural and entertainment applications together had revenues more than $1 billion in 2010. Residential lighting — the fastest growing segment of the market — starting from a small base, is forecast to grow at a CAGR of 44% through 2014. Global revenues for LED luminaires in commercial/industrial applications are expected to be more than $1 billion in 2011. The outdoor area lighting applications, which benefitted from fiscal stimulus and the need for energy conservation, are expected to grow at a CAGR of 38% through 2014.

LED colour quality, CRI and binning

An interesting article explaining exactly what CRI and Color Temperature is. It also explains why you get less lumens per watt from warm white LED chip’s.

It's a little bit technical but contains some good knowledge for those new to LED Lighting design.

Portsmouth City Council Trials LED Street Lights from Gemma Lighting

Portsmouth City Council (PCC) is working with Gemma Lighting to trial the first LED street lights in the city. The Jupiter 60XL110 range of lights were designed and manufactured by the LED specialist in the UK and have the potential to cut the council’s street lighting bill by 50 per cent.

The Portsmouth fixtures are also the first LED street lights in the UK to have the control gear situated at the base of the column. To improve ease of access for the PCC maintenance team, Gemma Lighting designed a bespoke LED gear tray that contains both the driver and fuse, as well as accommodating a photocell.

The trial supports Portsmouth City Council’s low carbon vision, where it is committed to reducing emissions by 30 per cent from operational buildings, transport and waste by 2014. The Jupiter LED lights being trialled will reduce energy as they consume 70 watts compared to the 170 watts used by the current system. The fixtures’ photocell light sensor also automatically switches on the LED, reducing energy wastage normally experienced with traditional timer systems.

Portsmouth City Council said: “Our carbon management plan lays out measures for reducing the city’s carbon emissions over the next five years. It is initiatives such as this LED trial that could help us to do this in the future. The initial feedback from the trial has been encouraging and we will continue to monitor the LED lighting to review the benefits it could bring the city in the long-term.”

Gemma Lighting has already installed over 2,000 Jupiter LED Street Lights across the world. The Jupiter solid-state LED chips have a lifespan of 50-80,000 hours (10-15 years of use), are vandalism resistant and create a pure white light that improves safety for pedestrians and motorists. They are also easy to install with each fitting taking less than 30 minutes to fit and test.

Craig Manuel, Managing Director of Gemma Lighting, said: “Our products have been designed and manufactured in the UK for the last seven years. Both the energy and cost savings that can be made with our systems has already been proven in projects with the likes of BAA and Buckingham Palace. We are pleased that such customers recognise our reputation for excellence and are continuing to support UK manufactured products.”
