Title: Light diffuser and optical member using the same and optical device
Inventor: KOIKE YASUHIRO
IPC: G03B21/60
Filed: 2003-05-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a light diffuser which outputs bright diffusion light of a high color temperature.  <P>SOLUTION: The light diffuser 30 is constituted by dispersing first and second particles 1 and 2 (EX.: silicone resins of grain sizes 7.3 μm, 9 μm) into a matrix, such as PMMA. Both the particles 1 and 2 are unified in particle sizes respectively near model diameters (R1, R2: R1>R2). The particles which are little in the dependence of scattering efficiency on wavelengths relating to visible light and are excellent in the ability easily to let blue light pass equal to or above red light and to impart an angle spread to the diffused light are used for the first particles 1 and the particles which are strong in forward scatterability and hardly dropped in total ray transmittance in spite of the addition thereof at a high concentration are used for the second particles 2. The balance is improved over the entire part of the visible light and the spread of the diffusion angle is given to the particles by the first particles. The diffusion angle is tacked on by the second particles while the blue components are prevented from being excessively spread in the angle. The bright characteristics of the high color temperature are obtained when the light diffuser is applied to the imaging sections of a screen for image projection, a cap part of a white light source, etc.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
