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

Dialight Problems with Existing Technology
• 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

Dialight Advantages of LEDs
4
Dialight Advantages of LEDs
• 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)
LEDS are the most efficient white light source

Dialight LEDs = Reduced Voltage
LEDs: No high voltages
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 POWER
Capacitors can retain high charges.
Xenon systems
1,000 volts
or more
LED systems
150 volts
or less

Dialight LEDs = Long Life Fewer Costly Tower Climbs
FAA MINIMUM WARRANTY
Incandescent - 1 year (2,000 hrs)
Xenon - 2 years
LED - 4 years
