<P>PROBLEM TO BE SOLVED: To provide an illumination light source that can hardly peel off even if an internal member such as a board is adhered to an inner wall surface of an enclosure member for storing LEDs and hardly show bright spots by using a diffusion film with a high light transmittance and being highly efficient. <P>SOLUTION: The LED illumination light source, wherein bright spots are not seen by applying the diffusion film made of particles of calcium carbonate on the inner wall surface of the enclosure member of the illumination light source and it is highly efficient, is provided. Further, the safe LED illumination light source wherein the diffusion film is not peeled off even if the internal member stored inside the enclosure member is adhered and fixed on an inner wall and it does not generate failures and damages can be attained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
