LED Lighting Systems for Aviation Obstructions Improving safety, quality of light, and reliability makes financial sense
David Jessip Dialight Corporation Strategies in Light 2011 August 22nd, 2012 Problems with Existing Technology Dialight
• High power consumption • Short life • damaged solder connections of the contact pins • filament burn out • broken electrodes • cracked glass • EMI/RFI interference • Poor optical control = light pollution
2 Advantages of LEDs Dialight
3 Advantages of LEDs Dialight LEDS are the most efficient white light source
• Solid-state semiconductor technology • Smallest light source available • Mercury & lead free material (RoHS compliant) • No fragile glass • No fragile filament • No corrodible contacts • Shock and vibration resistant • Long life (can last more than 100,000 hours)

HAZARD WARNING Equipment may generate dangerous voltages. Exercise extreme caution at all times when operating, maintain, or servicing. AVOID TOUCHING LIVE CIRCUITS Avoid touching any component or any part of the circuitry while the equipment is operating. Do not change components or make adjustments inside the equipment. DANGEROUS VOLTAGES CAN PERSIST EVEN WITHOUT LEDs: No high voltages POWER Capacitors can retain high charges.
