Basic Advantages of LED Light
• LEDs are…very energy efficient >141LPWnow (near-term roadmap to >161LPW…)
• Are directional No wasted light, any patternpossible
• Have very long lifetime >50,000 hours to70% Lumen Maintenance (L70)
• Are inherently rugged No filament to break
Copyright © 2010, Cree, Inc. pg. 6
• Start instantly nanoseconds vs. > 10 minre-strike (HID)
• Are environmentally sound no Hg, Pb, heavymetals
• Are infinitely dimmable, controllable Newlighting features, power savings
• Love cold temperatures No cold startingissues

– XP-E: Up to 130 lm @ 116 LPW; up to 291 lm @ 84 LPW
• Design flexibility with one footprint
– Reduce system cost by using fewer LEDs & fewer optics
– Easily create different price / performance levels
• Superior optical control – put light where it is needed
– Small optical source size works well with reflector & TIR solutions

The advantage of LEDs in street lighting
• 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.
Copyright © 2010, Cree, Inc.
The advantage of LEDs in street 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.
Copyright © 2010, Cree, Inc.
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
Copyright © 2010, Cree, Inc. pg. 56
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
Copyright © 2010, Cree, Inc.
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
Copyright © 2010, Cree, Inc. pg. 59
Summary
• LEDs time has come
– Technology is ready
– Economics work for now for many installations
• Buying motivations go well beyond pureeconomics
Copyright © 2010, Cree, Inc. pg. 60
– 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
