Abstract
The present disclosure relates to lenses for lamp assemblies, for example, for automotive lamps such as head lamps, or perhaps tail lamps, turn signals, brake lamps, cargo lamps, and the like. These lamps may use incandescent or High Intensity Discharge (HID) lamps which generally create enough heat to reduce or eliminate fluid that may form on the lens such as in the case of condensation, rain, sleet, snow, ice, fog, and the like. Such a buildup of fluid may result in suboptimal light transmission and may degrade the performance of the lamp to a degree that renders it temporarily unusable, particularly in poor weather. This is especially concerning in the case of some types of Light Emitting Diode (LED) lamps where the lamp may not produce sufficient residual heat to effectively remove the fluid that may build up on the lens either in liquid or solid form, and especially in colder weather.
