• Lighting consumes up to 34% of all electricity in USA (source

Worldwatch Institute)

• Lighting consumes 19% of all electricity in the world (source IEA)

Lighting 19%

Other electricity 81%

Sustainability

• Revolution in lighting technology during the past 10-15 years.

• Approximately 2/3 of all lighting currently installed is based on older, less energy efficient technology (developed before 1970).

• Our current changeover rate to new lighting technologies is simply too slow: e.g. Street lighting 3% per year, Office lighting 7% per year.

White Light

Artificial light vs. natural daylight

Until now, only orange/yellow light (HPS, LPS) was efficient

White LightBeating the Darkness

Aesthetic Enhancement – Ambiance

• Effect closest to sun light

• Brings out the best in buildings and streets

• Best natural ambience - perceived as more authentic

• Most flexible color, works with all building materials

• Fresh and bright - lifts the atmosphere

Security – background facts

Various research shows:

•People fear for their safety around unlit areas

•White light reduces fear and crime and is economically attractive

Lighting Research Center, USA (2007)•White light is still preferred even when using only 1/3 of the light level (5 vs 15 Lux)

•At the same light levels, >80% of people feel safer with white light.

• Perception of safety is similar to HPS, when light level of white light is 30% lower.

Safety – Accident Prevention• Drivers see hazards more quickly and from

a greater distance – less stopping time

• Pedestrians see ongoing traffic earlier, and react accordingly

• Obstacles on footpaths seen more easily

Energy Efficiency – Air Pollution

• Reduce the required amount of light• Increase pole distance • Consumes less power

Save money and the environment

67% Energy saving

Advantage of white light•Level of illumination on subsidiary roads and paths may be reduced a further 30% when color rendering is sufficient (CRI>60).

Summary: Trends in Lighting Support Sustainability

Minimize Total Cost of Ownership• Initial investment costs

– Luminaires, poles, lamps, cabling• Running costs

– Energy costs– Lamp replacement costs– Maintenance

White Light• Improves security – safety• Prevention of accidents• Creates ambiance – enhances aesthetics

Environment• Energy – CO2 reduction• Minimize light pollution
