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.
Claims33
An illumination assembly, comprising:
- a housing forming an enclosure configured to contain an illumination source, the housing including a light transmission portion;
- a wall portion associated with the housing;
- a port provided in the wall portion;
- a projection disposed at least in part within the port and carried by the wall portion;
- and
- a non-illuminating heat source supported by the projection in heat transfer relation with at least one of the housing, the light transmission portion, and a gas within the enclosure of the housing.
An illumination assembly, comprising:
- a housing including a light transmission portion forming an enclosure configured to contain an illumination source;
- a wall portion associated with the housing;
- a hole provided in the wall portion;
- a projection operatively associated with the hole and carried by the wall portion;
- and
- a non-illuminating heat source supported by the projection in heat transfer relation with at least one of the housing, the light transmission portion, and a gas within the enclosure of the housing.
An illumination assembly, comprising:
- a housing including a light transmission portion forming an enclosure configured to contain an illumination source;
- a wall portion associated with the housing;
- a seat provided by the wall portion;
- a projection operatively associated with the seat and carried by the wall portion;
- and
- a non-illuminating heat source supported by the projection in heat transfer relation with at least one of the housing, the light transmission portion, and a gas within the enclosure of the housing.
An emitter assembly, comprising:
- a housing including an electromagnetic wave transmission portion forming an enclosure configured to contain an electromagnetic wave source;
- a wall portion associated with the housing;
- a seat provided by the wall portion;
- a projection operatively associated with the wall portion;
- and
- a non-illuminating heat source supported by the projection in heat transfer relation with at least one of the housing, the electromagnetic wave transmission portion, and a gas within the enclosure of the housing.
