2 Advancements in Solid State Lighting System life Performance and Cost trends More than Cobra Head Replacement ANSI C Update Adaptive lighting controls RP Update and other RLC Updates

3 LED benefits over HID Uniformity White light Fixture efficiency, less power Less maintenance Precise placement on the roadway All these things are good arguments for lower lumen fixtures, but which one do you use? What is an equivalent to HPS?

4 Fixture life parts of an LED fixture LED is a different animal. It is NOT HID Light Emitting Diodes (lamps) LED s less apt to die than dim Driver (ballast) 50,000 hours, 100,000hours. Look at Tcase temperature Surge Protector Class C for outdoor Photocell LED specific, rated 10 or 20 year.

LED Fixture. As you can see, LED components require far less maintenance than an HID luminaire.

5 Operating Costs: Reduction in maintenance over lifetime The Weak Link % Less Maintenance This schedule represents the average time to replace key components of both an HID cobrahead and a LED Fixture. As you can see, LED components require far less maintenance than an HID luminaire. HID ballast: every 8 years HID lamp: every 4 years Photocontrol: every 10 years LED driver: every 20 years LED control every 10 years

6 2 of 3 IES Standards for LED Lighting

7 LED Lamp Lumen Depreciation Lumen Maintenance curves define LED life. Varies with temperature. L70 = 70% of Lumen Maintenance of initial output IES TM-21 provides consistent method to predict life Based on LM-80 data At specific temperatures (55, 85,?) Two numbers to look for: Reported -> 36khrs - 6 times test interval Projected -> lumen maintenance and L70 values

Calculating Light Loss Factor LLF should be determined (and justified) by manufacturer LLF= LDD X LLD Impact of Luminaire design on LLD for HID is minimal Impact of Luminaire design on LLD for SSL is

8 Calculating Light Loss Factor LLF should be determined (and justified) by manufacturer LLF= LDD X LLD Impact of Luminaire design on LLD for HID is minimal Impact of Luminaire design on LLD for SSL is significant Justify Using: TM-21 Calculator LM80 Data ISTMT data (UL1598 thermal test) (In Situation Measurement Test) DOT should determine: LLD End-of-Life in Hours Outside Ambient Light Loss Factor (LLF) Light Lumen Depreciation (LLD) Luminaire Dirt Depreciation (LDD) 8

20 LED Tunnel Applications- Tough Environments Tunnels Operate 24 hours per day Corrosive environment due to high levels of exhaust fumes, humidity, and fluctuating temperatures High vibration due to truck and trailer traffic Require luminaire to be low profile so as to avoid whipping trailer tarps and antennas Luminaires must withstand periodic high pressure hose down Luminaires must be easy to install and maintain

29 ANSI/ IESNA RP8-?? Roadway Lighting Scotopic, Mesopic and Photopic : What does it all mean with the New RP-8-201?* changing from Illuminance to Luminance Readings. (* Hopefully 2014!)

30 Coming From the IESNA Roadway Committee RP8-14 Approved by the Board, now out to ANSI for 60 Day Public Comment June-ish if all goes Well RP20 Parking Lots: Out for Comment RP : Tunnels Starting Drafts for new RP for 2016 Design Guides: DG4 Maintenance has been approved and is out to be printed. DG9 Rest Areas, in process to get up to date. DG19 Intersections (Formally Roundabouts) in process of being formed. DG21 Residential Street Lighting are revising final public comments and will be sent to the Board for final approval DG23 Toll Plaza s approved and going to the printer. DG28 Controls Design Guide is out for public comment and a committee vote. DG30 High Mast Going to Standard Committee for Comment 30

31 Illuminance Luminance Amount of light hitting something Measured in lumens per square foot (foot-candle) or lumens per sq. meter (lux) Easy to measure We correlate task performance with lighting level Amount of light reflected from or transmitted through a surface in a given direction Measured in candela per square meter Intensity divided by luminous area of the luminaire Correlated with Brightness.

32 Scotopic, Mesopic, Photopic Levels Scotopic <.001 cd/m 2 Mesopic.001 to 3 cd/m 2 IES average is from 0.3 to 1.2 Photopic > 3 cd/m 2 Scotopic Mesopic Photopic IES Road Avg
