Efficient irradiation system using curved reflective surfaces

摘要

An assembly and method for irradiating a surface utilizing a plurality of LEDs in a pattern such that a linear fill factor characterizing such pattern is at least 80% along a focusing direction and/or at least 20% along a direction transverse to said focusing direction, the radiation emitted from the LEDs and reflected onto the surface from a trough reflector.

主权项

1. An assembly for irradiating a surface with UV radiation, comprising:
a reflector; and an array having a plurality of discrete UV light sources arranged spatially in an array pattern with a focusing direction and a direction normal to said focusing direction, a linear fill factor of said pattern being at least 80% along said focusing direction and at least 20% along said normal direction, said UV radiation emitted from said sources and reflected by said reflector onto the irradiated surface; wherein said reflector is configured to reimage and focus light from said discrete sources by creating a focused, substantially uniform one-dimensional line of irradiance suitable for curing applications which is imaged substantially free of non-emitting gaps and spaces between said discrete sources onto said irradiated surface.
