Law of Unintended Consequences: LED Traffic Lights
Dec 16, 2009 – What can go wrong with LED traffic lights that use 90% less energy by producing less heat? There is such little heat produced that when there is a snow storm and the snow is that particular “sticking snow”, it covers over the traffic lights and there is not enough heat to melt the snow and drivers can’t see if they have a green or red light. Do you have a solution for this problem? If so, please leave it here.
Sometimes the heat produced by incadescent bulbs is beneficial in cold climates. The traffic light is one example. Several incadescent bulbs in a small room can add a noticeable amount of heat. This can be desirable in a cold climate.
