LEDs light the future

The Light of the future

• LEDs are the light of the future and the most innovative frontier of lighting, used in modern

context worldwide, therefore their use in growing in outdoor as well as indoor applications

due to:

• Increasing prices of electricity and other energy sources and general expectation they will

keep on raising

• Need of energy efficiency sources, that allow to cut costs and that can be managed • Environmental consciousness that is leading costumers and companies to choose

environmental friendly solutions (portraying an image of green consciousness is becoming more and more important )

LEDs reasons -why

LEDs allow to cut costs and energy wastes up

to 80%-90%

LEDs emit superior quality light

LEDs integrate and exploit different

technologies up to ICT and can be remote

controlled

LEDs allow to get impressive lights effects,

both static and dynamic

LEDs use reduces energy waste, costs and

CO2 emissions

3

The future begins

• LEDs (Light Emitting Diode) are not just warning lights, they are the future lighting source

4

– LEDs are electronic devices able to emit light

– Light (photon emission) is generated by electric current

flowing between the poles of a semiconductor

– Light colour depends on the combination of phosphorus layers

overlapping the silicon junction which determines light

wavelength/frequency

OK

PHOTOVOLTAIC

As the light flows, silicon produces

electrons (current)

SI

As the current flows, silicon emits photons

(light)

LED

• LEDs have been around for almost five decades now, but it was only over the last 10-15 years

that they have made considerable progress in the field of lighting

• LEDs are a technology which is innovating lighting systems and generating benefits for

everybody:

Think positive, think LED

– Conceptual change: from ‘consumption costs’ to ‘waste cut’

– Huge energy conservation

– Project operating sustainability

– Improves corporate image

– Maximizes security

– High quality standards

• One LED emits the same light of 11 traditional bulbs put together, since its luminous

efficacy (in lumen: light flow unit of measurement) is more than 10 times the one of

incandescent lamps

10 times more efficient

• LEDs use allows to cut energy waste and costs thanks to their luminous efficacy and since they

require low energy consumption

• LEDs luminous efficacy can reach 80% while incandescent lamps reach just 20% since,

producing energy through a burning filament, 80% of their energy is wasted into heat

More light, less energy

15

A traditional 100W incandescent lamp lighted for a year at a cost of 10 cent. per kilowatt-hour would cost ca. 88 Euro

BUT

80% of this amount would be spent to heat the room rather than light it!

A light as light as fresh air • Reducing energetic consumption means to limit CO2 pollution. Thanks to LEDs use we get:

– Environmental and social benefits both in the short and long term

– Corporate image improvement in terms of positive associations that represent a

competitive advantage – i.e. GREEN positioning, social responsibility, forward-

looking management

Long life span

• LEDs can be lit 24 hours for more than 5 years: they last 50 times incandescent and 12

times halogen lamps. LEDs superior resistance is due to the fact that they are free from

fragile materials (i.e. filament or glass wrapping)

More security, less maintenance

• LEDs use cuts systems maintenance costs and guarantees absolute security thanks to:

– Superior life span compared to traditional lamps

– Strength due to the lack of glass parts and filaments that wear out with heat

– Resistance against impacts, shocks and vibrations

– Full security operation since they work with very low tension

– Tolerance to heat range (-40°C up to + 80°C)

– Focused maintenance thanks to remote control (industrial/logistic applications)

18

• LEDs do not need additional circuits to turn on, therefore do not imply additional

costs as traditional lighting systems

• LEDs light has a colour equal to the face value immediately after being turned on

Immediate light

• LED technology integrates both Lighting and Building Automation know-how in order to

offer optimized light remote-control systems
