Agenda

• Advantages of Led for Street Lighting applications


Visible Light Spectrum of Various Sources

The Sun Incandescent


LED

The advantage of LEDs in street lighting

Significant and continuos development ofthe LEDs in terms of light output, efficacyand lifetime expectancy


Important criterias of the LEDs instreet light applications

Street lighting especially can now be addressedusing LED technology


LED-based lighting

helps save money

through…

… reduced maintenance

Twenty percent of theworld’s electricity is

used for lighting

… reduced maintenance

… and innovative dimming approaches to achieveelectricity saving



• Desire for enhanced visibility with better colorrending

• Growing community pressure to minimize lighttrespass and light pollution LED fixtures are designedto spread the light more evenly, eliminating the needfor over-lighting.for over-lighting.



...in terms of numbers:

• Long life and high reliability. Quality street lightscan last 10-25 years depending on usage and cantherefore offer significant reduction inmaintenance costs compared with traditionallights sources that require replacement every 2-3lights sources that require replacement every 2-3years.

• High efficiency with the potential to offer 50 to 80percent energy savings.

• ”Smart Street Lighting” can help to achieve evenfurther electricity and $ savings.


Expectations vs LEDs in street light applications

• High flux output + low forward voltage highefficiency

• Long lifetime (LM-80 LED lifetime testing )

• Lower thermal resistance (eases thermal design)• Lower thermal resistance (eases thermal design)

• Very stable light-output over junctiontemperature (less than a 20% drop across a 25 to110° C junction temperature range )

Agenda

• European standards


European Standards

• In Europe EN 13201 defines the standards forstreet lighting

• Areas involved: highways, urban streets,junctions and sidewalks

• The normative defines a classification for eachroad type for getting the reference lightingroad type for getting the reference lightingcategory. For example:

type A1 - Extra-urban Highway – speed limit 130-150km/h - Reference

lighting category: ME1

Type F - Urban local roads: town center, ambiental isles, zone 30 – speedlimit 30km/h - Reference lighting category: ME4b


European Standards

• The normative have 4 parts (EN13201-2,EN13201-3, EN13201-4) which define acceptableluminance and uniformity, the algorithms and themethods of measurement of the performance

• LED based street lights

can respect the EUcan respect the EU

standard with the use

of secondary optics


Agenda

• Summary


Summary

• LEDs time has come

– Technology is ready

– Economics work for now for many installations

• Buying motivations go well beyond pureeconomics


– Consumers, municipalities, and businesses are readyfor GREEN lighting solution

• LEDs are a paradigm change from bulbs

– Must think in terms of LUMINAIRES, not re-lamp

– Luminaire design for LEDs will be different andrequire new expertise
