Self De-Icing LED Signals
This proposed project will develop multiple prototypes of a new type of self de-icing LED signals for highway signalized intersections and railroad signaling applications and validate them using the field tests. The innovative concept -- "Heated Lens Lighting Arrangement" -- was thoroughly tested in 2014. A non-provisional patent application (No. PCT/US14/53503) was filed on Aug 29, 2014. The self de-icing LED signal light is aimed to solve a well-known problem of the existing LED signal light that does not generate sufficient heat in the forward direction towards the lens of the signal necessary to melt snow and ice. Snow and ice can easily accumulate on the lens within the signal hood in wintery conditions and block light to the drivers of vehicles or locomotive engineers. This can decrease the performance of signalized intersections and railroads and also result in collisions in inclement weather conditions. This is a problem in the snowy regions in North America for which a viable retrofit has not been developed or tested.
