Night vision LED solutions for efficient outdoor lighting

Taking LEDs outdoors LEDs provide big advantages for lighting users: low energy, long life and less environmental impact. For outdoor lighting, these benefits are particularly important and GE has developed a comprehensive range that enables users of outdoor lighting to make the most of the LED revolution. This guide shows the range and its benefits.

GE Lighting was the original innovator of the first largest LED systems companies in the world, covering applications such as transportation, signage, outdoor area lighting, and retail display lighting. Its credits include more than 7.62 million metres of LED linear lighting with a warranty return rate of less than 0.05%. In the 2009 Lighting Design Award ourVio™ LED technology was recognised by the judges as 'a major advance in colour stability'. GE also received 'Best in Class' awards in 2008 and 2009 at the Next Generation Luminaires competition sponsored by the US Department of Energy, for...

Save energy Colour performance LED light engines use 30-60% less energy than other light sources, with no loss of light output, which represents considerable cost savings as well as major reductions of greenhouse emissions. Furthermore, LED technology allows designers to create fittings that utilise light far more efficiently, delivering light uniformly and only where it is needed, with minimal glare. LED light engines provide light quality that is second to none, with a CRI value of over 70 that yields high quality colour rendering. This enables realistic colours to be seen when objects are...

Facing the challenge As you would expect from an organisation with over a century of technological heritage, GE believes that the imaginative use of technology plays an important part in solving the environmental challenges that face the modern world. GE has many technical innovations to its name and in the field of lighting these include the first incandescent lamp, fluorescent tube and halogen lamp. There is no company better qualified to lead the lighting industry’s challenge to reduce environmental impact. 6

This philosophy is embodied in ecomaginationsm, GE’s initiative to create a better quality of life for all the world’s citizens and create long-lasting environmental solutions through the use of technology. ecomaginationsm is at the core of many of GE’s technologies and GE Lighting has made a major contribution with high efficiency products right across the range. But there is more to it than efficiency. GE aims to produce products which have the least possible environmental impact during production and also when their useful life is finished. There is no better example of these qualities than...

lighting. Not only are there the physical demands of weather and the city environment but outdoor luminaires must also perform as efficiently as possible to reduce energy use and keep publicly achieved. Furthermore, outdoor lighting must provide a safe and secure night-time environment in cities that operate 24/7. LED lighting, together with careful product engineering, is GE's biggest ally in meeting these needs. It is a solution that has been developed on four levels - the four dimensions of

1 3 2 4 Optical GE LED fixtures have carefully designed optics that ensure that light only goes where it is needed. This reduces wastage and cuts down light pollution. In addition to the quality of the optics, GE also focuses on providing a wide choice of optics so that lighting designers can light many different types of application as efficiently as possible. • • • • Variety of light distributions Excellent cut-off Horizontal and vertical uniformity Unique reflector design Standard optics 10 GE LED optics - light only where it’s needed

The GE LED Engine At the heart of GE’s high efficiency LED luminaires is GE’s unique LED Light Engine, an Optical Ring system in which LEDs and optics work together to provide lighting performance that is second to none. LEDs are placed precisely on the reflector surface in order to maximise the efficiency of the required light distribution, delivering light only where it is needed. A specially designed heat sink ensures that the efficiency of the system is maximised. • • • • • • Good, even, vertical illumination. Excellent method for meeting light trespass requirements. Maintains photometric...

1 3 2 4 Design The award-winning designs of GE LED luminaires are efficient and future proof so that maintenance is minimal and updates can be easily performed. They are also designed to be as flexible as possible in use so that the lighting needs of a complex site can be provided for by one product or product range. • • • • 12 Excellent thermal management Best-in-class LEDs Variety of shapes Variety of mounting options, eg post-top, wall-mount etc. • Easy maintenance and upgrades through LED engine replacement • Award-winning designs

Designed flexibility The GE Iberia LED luminaire has been designed to suit a wide range of installation configurations, including wall and pendant mounting. Lighting designers can meet all the needs of a project with one high efficiency LED range, for consistency of Post-top double Post-top triple Managing heat The management of heat plays an important part in the performance of a luminaire. Heat sinks inside fittings, together with outer surface areas equipped with features such as heat fins, ensure that luminaires are as heat-efficient as possible. In addition, interior layout is always carefully...
