Purpose of Obstruction Lighting History, Regulations, Specifications Lighting Systems Configurations and Types Lighting Technologies LED Technology Overview LED “Challenges and Concerns” Manufacturer responsibility Controllers & Alarms Recommended maintenance procedures Question and answers Overview of presentation

  4. Purpose of Obstruction Lighting

  5. The Evolution of Tower Lighting -Red Code Beacon (300mm) and sidelights - White Strobe, High Intensity - White Strobe, Medium Intensity - Red/White Dual Strobe, Medium Intensity - Red LED Sidelight - Red LED Beacon, Medium Intensity History

  6. - FAA Advisory Circular 70/7460-1 “Obstruction Marking and Lighting” FAA Advisory Circular 150/5345-43 “Specification for “Obstruction Lighting Equipment” FAA Engineering Brief 67 - FCC Part 17 - ICAO Annex 14 - VAP Draft Specification - Transport Canada CAR 621.19 (formerly TP-382E) - Secretary Communications-Mexico IEC Draft Lighting Regulations / Certifications

  7. Red lighting/paint is an option for any height tower for daytime marking. Medium Intensity white lighting may be used in lieu of paint on structures up to 500’ tall. High Intensity white lighting may be used in lieu of paint on structures over 500’ tall. FAA Tower Lighting Configurations

  8. FAA System Configurations TYPE ARed Lighting System TYPE BHigh Intensity White TYPE C High Intensity White with AOL’s (on appurtenance) TYPE D Medium Intensity White TYPE E Dual Lighting System Red / White Medium Intensity TYPE F Dual Lighting System Red / High Intensity White Dual RED/White Medium Intensity Beacon on Appurtenance Over 40’ Tall

  9. Day: Aviation orange and white paint Night/Twilight: Flashing red beacons & steady burning obstruction lights (2000 candela and 32 candela) Light Sources: Incandescent, Strobe and LED Advantages: Least complex lighting system Relatively low purchase price Disadvantages: Painting increases life cycle cost Red Lighting Systems

  10. FAA Designations: L-864 Beacon ICAO Designation: Medium Intensity Red Light Industry Jargon: Red Beacon, 300mm Beacon, 864 Flashing Red Beacons

  11. FAA Designation: L-810 ICAO Designation: Low Intensity Light Industry Jargon: Sidelight, Steady-Burner, OBs, Marker Light, L-810 Steady Burning Obstruction Lights

  12. Day/Twilight: 20,000 candela white Night: 2,000 candela white -no sidelights required Advantages: No painting required Less expensive than dual lighting Disadvantages: White strobes at night can irritate neighbors, High voltage, High tech components can mean expensive maintenance Light Sources: Xenon gas strobe tubes Medium Intensity White only Lighting

  13. FAA Designation: L-865 ICAO Designation: Medium Intensity White Light Industry Jargon: Medium Intensity Strobe, White Strobe Medium Intensity Strobes

  14. Day/Twilight: 20,000 candela white Night: Flashing red strobe & steady burning obstruction lights (2000 candela and 32 candela) Light Sources: Xenon gas strobe tubes Advantages: No painting required, strobes brighter Efficient light source Disadvantages: High voltage, High tech components can mean expensive maintenance Medium Intensity Dual Strobe Systems

  15. FAA Designation: L-864 / L-865 ICAO Designation: Medium Intensity Dual Light Industry Jargon: Dual Strobe Medium Intensity Dual Strobes

  16. Day: 200,000 candela white Twilight: 20,000 candela white Night: 2,000 candela white Advantages: No painting required Less expensive than dual lighting Disadvantages: White strobe at night can irritate neighbors, very expensive to maintain High Intensity Strobe Systems

  17. FAA Designation: L-856 for tall structures ICAO Designation: High Intensity White Light Industry Jargon: High Intensity Strobe High Intensity Strobes

  18. What are the options & what’s the best? - Incandescent - Strobe - LED Light Sources

  19. Advantages : Lowest “up front cost” Numerous distribution sources Fairly resilient to lightning Plug and play to most broadcast towers Disadvantage : Short lamp life, high “reoccurring costs” Frequent maintenance Susceptible to vibration damage Extremely inefficient, Consumes lots of power Light Pollution, ground effects! Incandescent Light Sources

  20. Advantages : -Longer life technology than incandescent. -Efficient power consumption -Numerous distribution sources Disadvantage : -Large “upfront” costs -Proprietary replacement technology -New electrical infrastructure -Limited lamp life, depending on design -EMI / RF issues and ozone release -Expensive High Voltage replacement components -Expensive maintenance costs - Light Pollution, ground effects! Strobe / Xenon gas Light Sources

  21. LED obstruction lighting Advantages Lowest cost of ownership Plug and play with existing infrastructure, 120VAC Solid State, extremely robust ad reliable, impervious to shock/vibration. Extremely energy efficient power consumption. 48 Watt beacon Precision optics. Warranted performance! No EMI created or susceptibility Not prone to damage from surge/lighting. Numerous distribution sources Disadvantages Reputable manufacturer with extreme knowledge of LED based products is a must! Light Emitting Diodes!

  22. Development timeline -60’s & 70’s calculators and watches -80’s: Interior uses such as panels, PC’s -90’s: Traffic Intersections & Brake lights -2000 Obstruction, railroad, aircraft, -2005 - UL, Class 1 Div 2 area white lighting -Today and beyond: General illumination! LED’s (Light emitting diodes)

  23. Going from a light bulb to a light engine Generally, a single LED cannot replace a single light bulb A “Light Engine” is required Making the transition…..

  24. 150 Electrical Discharge Lamps 100 Fluorescent 50 Incandescent 0 A revolution in lighting…LED’s High Pressure Sodium Light Emitting Diodes Metal Halide Luminous Efficiency (lumens/watt) Mercury Vapor Shaped Reflectors Tungsten Halogen Conventional Incandescent 1920 1940 1960 1980 2000 2020

  25. All LEDs are not the Same 5mm High-Flux LED LED Chip Plastic Lens Body Cathode Lead Anode Lead Slug

  26. Use the Right Technology for the right job! SnapLED Through-Hole Surface Mount High Flux Surface Mount Technology

  27. 5mm vs. High Flux performance Comparison

  28. LED performance is influenced by temperature 500 Candelas @ 25 O C 10% 34% 63%

  29. LED degradation increases with current density Current Densities

  30. Concerns and Challenges: Defining End of Life? • What is the difference between the end of life of an LED and that of a halogen or incandescent lamp? • Incandescent/Halogen is catastrophic…whereas a LED light output degrades • The question one should ask is: • What is the USEFUL LIFE or EFFECTIVE LIFE of an LED fixture? • Completely dependent on many variables 100,000 hrs.

  31. Ultimate Solution: Responsible Designs and Manufacturer Warranties Manufacturers must take the lead to ensure that their products meet the minimum operational and intensity requirements at the end of the product’s warranty period!

  32. Dialight DOES NOT manufacture controllers or produce lighting “systems” as our focus is on LED technology. We focus on upgrading / retrofitting existing lighting systems to LED based fixtures Installing new LED fixtures with the partnerships with the industry OEM’s. Please contact the vendor of your choice or visit our website for a list of our existing distributors and OEM partners. A side note….controller and monitoring systems

  33. All technologies Clean exterior optical portions of fixture Inspect and verify controller failure modes by creating a fault Inspect conduit & wiring for degraded connections Incandescent Ensure minimum of 120 VAC at lamp Inspect Gaskets & Seals around Fresnel lenses Strobe Tube Inspect high voltage controller capacitors and trigger cards Inspect fixture wiring and terminals for corrosion (Ozone) Re-lamp tubes per manufactures warranty (2-3 years) LED Re-lamp and install new gasket every 10-12 years Ensure 85 VAC at lamp Minimum Maintenance Procedures
