Reengineering LED Traffic Lights to Prevent Snow or Ice Buildup?

Student: Maxwell Poole

District/Region: Tri-County District

Event: 2010 Canada-Wide Science Fair

Grade 9 - Maple Grove Education Centre

The project tested if LED traffic lights could be reengineered with cost efficient heat energy to prevent snow or ice buildup.

A green LED traffic light was fitted with the proper amount of resistance wire to achieve a 15 watt grid heating element. In an ambient temperature of -17 degrees Celsius the lens temperature rose to +3 degrees Celsius, with average cycling of the light.
