According to aspects of the embodiments, a lighting fixture is designed to help prevent the accumulation of snow or ice on the light emitting face (e.g., lens) of the lighting fixture. The lighting fixture harvests both the light and heat generated by at least one light source, such as but not limited to at least one LED light source. The lighting fixture adopts a flip-mount light source mounting design in which one side of a passive heat exchanger is mounted or secured closely adjacent or proximate to the lens, and the light source is mounted or secured to another side of the passive heat exchanger. The heat generated by the light source is conducted by the passive heat exchanger to heat the lens. Additionally, the light emitted from the light source is redirected back through the passive heat exchanger and to the lens using a bundle of light fiber cables.
