OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. Obelux LED-Obstacle Lights Technical Overview OBELUX-OY IS EXCLUSIVELY REPRESENTED BY TECHNOLIGHTS SENC LUXEMBOURG IN THE MIDDLE EAST AND GCC REGIONS

OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. 2 What is a LED? LED - Light Emitting Diode A semiconductor component similar to transistor or integrated circuit Electrical current through the semiconductor chip produces light Semiconductor materials used, define the colour of light produced

OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. 3 Benefits of LEDs Extremely reliable: MTBF (Mean Time Between Failures) is millions of hours Very long lifetime: light output degrades % after 11 years of continuous operation High luminous efficiency: 30 lumen/watt of LED light compared to 5 lumen/watt of white light with red filter

OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. 4 Benefits of LEDs (cont) Shock and vibration proof Small dimensions Lightweight Virtually no heat generation Accurate and well controlled beam spread

OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. 5 ICAO Obstacle Light ICAO (International Civil Aviation Organisation) defines minimum reuirements for obstacle lights ICAO low intensity Type A steady burning red light: Minimum intensity 10 cd at +6° and +10° elevation angles Vertical beam spread 10° ICAO low intensity Type B steady burning red light: Minimum intensity 32 cd at +6° and +10° elevation angles Vertical beam spread 10° ICAO medium intensity Type B and C, flashing and steady burning red lights: Intensity 2000 cd ± 25 % at 0° elevation angle Vertical beam spread 3°

OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. 6 FAA Obstacle Light FAA (Federal Aviation Assocoation, USA) defines minimum requirements for obstacle lights FAA L-810 low intensity steady burning red light: Minimum intensity 32.5 cd lie between +4° to +20° elevation angles Vertical beam spread 10° FAA L-864 flashing red fpm, FAA L-885 flashing red 60 fpm Intensity 2000 cd ± 25 % at 0° elevation angle 750 cd throughout a minimum vertical beam spread of 3° Vertical beam spread 3°

OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. 7 Obelux LED Obstacle Light Low and medium intensity models for ICAO and FAA requiremens Special –HT-CST model for high temperature ambient Contains appr pcs high-intensity LEDs Power consumption <2-7 W Estimated lifetime years in continuous operation Very low wind load Variants available for AC and DC power supplies UV resistant Corrosion free No RF-Radiation

OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. 8 Real Life Statistics More than LED obstacle lights delivered since 1996 and only few failure caused by LEDs or other componets LED obstacle lights can survive even direct lightning strikes

OBELUX AERONAUTICAL LIGHTS Obelux, the LED-light company. 9 Why to Use LED Obstacle Lights? Maintenance free Very long lifetime Very low power consumption Very low overall cost of ownership FOR FURTHER INFORMATION AND TECHNICAL DETAILS CONTACT: RUE DE LA CHAPELLE 8017-STRASSEN- LUXEMBOURG TEL FAX
