Abstract
A heated light enclosure having an adaptable heating system is provided with a controlled heating system to deliver enough heat to a lens on a lamp assembly to remove snow, frost, and/or condensation without overheating the lens. By heating the lens using a combination of one or more of PTC heaters, heat sinks and heat pipes, accumulation of snow, ice, or vapor is mitigated or eliminated from a surface of the lens, thereby enabling light to transmit through the lens. Applications include lamps and bulbs on conveyance devices, including vehicles, boats, planes, and trains, as well as sedentary structures, such as lamp posts, street lights, railroad crossing markers and lights, and airport ground and runway lighting systems.
