ELEVATED RUNWAY/TAXIWAY FIXTURE AND GLOBE/GLASS HEATER

摘要

A light fixture is provided with a heating element. The heating element can be a resistive heating element, such as a Nichrome wire, and resides in grooves of a cover (e.g., a glass globe) of the light fixture. Thus, the heating element acts to directly heat the cover of the light fixture to prevent, decrease, or otherwise correct frosting, freezing, and other elemental effects on the cover when it is exposed to the environment. The heating element is capable of raising the temperature of the cover at least 15°C from an initial temperature of -20°C in 30 minutes. A heat sensing element may provide feedback regarding the temperature of the cover for controlling power supplied to the heating element.
