Abstract:
A mixing light module includes a matrix, a fluorescent film, and a plurality of micro-structures. The matrix includes an incidence surface, an emission surface and a reflective surface. The fluorescent film disposed on or above the emission surface has an upper surface and a lower surface and includes a plurality of fluorescent particles. The matrix receives a first light having a first wavelength, and the reflective surface reflects the first light to make the first light to be emitted from the emission surface. Since the plurality of fluorescent particles receives a part of the first light from the emission surface, the plurality of fluorescent particles is excited to emit a second light having a second wavelength. The second light and the first light are mixed into a predetermined light. The plurality of micro-structures is used to make the first light or the second light uniform.
