  • 1. LED Street lights:state of the art Dledsproducts
  • 2. The main reasons why the LED lighting is becoming an important role in the industry can be summarized with the following key factors:
    Big energysavingreplacingexistingsystems
    Energy saving on newsystems
    Life of the newtechnology
    Reductionof the maintenancecosts
    Better light quality
    Free chooseof the color temperature
    High electricalsafety and power-onlight immediately

    LED key points
  • 3.
    • Most of the lighting fixtures in our countries are outdated and obsolete.
    • 4. The recovery of energy efficiency appears to be a major factor in the consideration of the LED source as an alternative to the existing one.
    • 5. The use of LED technology in the municipal area can be used for street lighting fixtures but also for lighting road bike paths, walkways, gardens, parks, common areas, parking lots, etc..

    • Whenwespeakaboutpercentageenergysavingof the LED fixtureto the standard existinglamp, wemeanhowmuch the new LED light can savegivingas a target the respectof the lighting classof the EN13201.
    • 7. Untilfewtimes ago, the choiceofone light fixtureratherthenanotherwasmadeconsideringaesthetic and performances. Sometimesthischoiceappearsexceeded.
    • 8. If, forexample, sphere light fixtures are replaced ( emitting on 360°) the recoveryof the energyefficientwillbeprobably the max. possible.
    • 9. We can therefore say that the use of LED light fixtures can improve the efficiency between 30 and 70% depending on the individual case.

    How much you can save in percentage terms by replacing the existing lighting with LED technology?
  • 10. Using LED lights on newsystems can achieveinterestingsavinglevels in considerationof the 2 followingissue:
    • Reductionofonelightingcategorythanksto the high colorimetricindex ( italianlaw UNI11248 )
    • 11. Actualavailabilityof led fixtureswith “real” efficiencyof more then 70 Lm/Watt
    • 12. Whatdoesitmean “efficiencyLm/Watt”?
    • 13. Sincethereis no rules on which information havetoappear on the catalogof the LED streetlightmanufacturers or importers, we assist to a different and sometimesmisleading information..
    Detas SpA - divisione DLEDS
    2. Energy savings on newsystems
  • 14. The efficiencydeclared in the catalog (forexample 100lm/watt or 5500 lm/watt if the lamphas 55 Leds) isrelatedto the LED efficiency at the JCT of 25°C ( asdeclaredby the manufacturer) or to the lamp in workingconditions ?

    Making a true compare between LED streetlights
    Extractfrom LED manufacturercatalog
    Appearsclearas the luminousfluxisreferredto the Junctiontemperaratureof 25°C : a conditionnotreal in the actualpractice
  • 15. Hereis the graphicwhichletunderstoodwhich can reallybe the efficiencyof the “system”
    Detas SpA - divisione DLEDS
    LED efficiency VS junction temperature
    • Therefore, the LED efficiencyisinverselyproportionalto the Junction Temperature
    • 16. ItissurelyimportantusingLEDswith high efficiencybutitisalsoimportantthat the lampisequippedwith a goodheatsink so that the Led can keep a high levelofperformances.
  • Anotherimportantfactoris the expectation in the life of the LED and alsohereitisnecessarytoclarify some importantmatters.
    The life of the LEDsdepends on severalfactors:
    • Kind and Brandof the used LED. On the market are probablythousandsofmanufacturersbutonly some ofthem can guaranteereliability, performance over the time.
    • 17. As the LED isdrivenand heatsinked. The junction temperature is the key tounderstandhow long can work the led.
    • 18. The LED package and whichreliabilityhas the led once mounted on the printedcircuitboard.

    3. Life timeof the LED
    Extractfrom LED manufacturercatalog
  • 19.
    • LED life can changefrom 50.000 to more then 100.000 hrsaccordingtowhichkindof led isused and from the junction temperature.
    • 20. The life of the Led fixturedependsnotonly on the abovementionedfactorsbutalso on whichkindof led driver isused and ifadditional electronic circuit are present.
    • 21. A led driver isreliableifitiscertified and if the MTBF isdeclared.

    3. Conclusion
  • 22.
    • The reductionofmaintenancecostsisreferredbasicallyto the life of the LED source, whichwehaveevaluated in 3-6 timesgreaterthen the traditionalsources.
    • 23. The reductionof the maintenanceisalsogivenby the fact the the Led is a cold light, meaningthat the light goingourof the lampiscool. Forthatreasonitattractslessinsects.
    • 24. The Led street light isan electronic device and ifitiswelldesigned and produced can last

    Severalstudiesarguethatthere are manyadvantagesof the LED light compared on the old light.

    The “white light” producedby the LED lightstogetherwith the high levelofuniformitymakes a bettereffect on the road.

    6. Environmentalfriendly
    LED lights do notcontainsanymercury or some otherdangerouscomponent. One LED light can bedisassembled and all can berecycled
    • AccordingtoStandfordUniversity the mercurycontent in thissmallfluorescent light can pollute 4000 litersof water.
    • 28. Whatabouttheselamps?
    • LED can beproducedwithseveral color coordinates.
    • 29. Wecallit “color temperature” in °K.
    • 30. A typicaloffer in the current LED market isabout 3000°K or less ( Warmwhite ) 4000 °K (Neutralwhite) and 5000 °K (coolwhite)

  • 31.
    • LED power-on light immediatelyare typically sold withclass 2 electricalsafety( doubleinsulation).
    • 32. Itmeansthat in case of a single failurethereis no contactwithanydangerousvoltagesfrom the user.
    • 33. This is usually achieved at least in part by having two layers of insulating material surrounding live parts or by using reinforced insulation.
    • 34. Itisveryimportantthat LED light turns on immediately
