Abstract (en)
[origin: WO9960303A1] To provide a light reflective film capable of easily controlling the directivity of radiation and the illuminating range in accordance to the operating conditions and also capable of effectively increasing the intensity of the emitted light of a light-emitting apparatus. A light reflective film intimately contacted with a light-emitting surface of a light source in such a manner that a part of said light-emitting surface is covered with said film, thereby the intensity of the light emitted from the remaining and uncovered part of the light-emitting surface is increased, characterized in that the light reflective film further comprises a dielectric reflective film having a reflective surface opposed to the light-emitting surface of the light source and a light-transmissive adhesive film intimately contacted with the reflective surface of the dielectric refractive film.
