Abstract
PURPOSE: To uniform light from a luminous surface, by employing a film, with the filtering effect against a visible luminous spectrum whose spectral transmission factor of visible wavelength efficiency is between 65 and 50% and spectral reflective factor is between 15 and 25%, as a light diffusing board shielding the photo semiconductor.
CONSTITUTION: Onto base body 1, wiring stripes 2 and 2' are provided, and photo semiconductor element 3 of GaP, etc., is connected to it and then, surrounded with reflector 4 with reflective surface 4a with characters, numbers, symbols, etc., formed. Next, a thin sheet of light diffusing board 5 is provided onto the entire surface, and this diffusing board 5 is composed as follows. A polyester film of approximate 120μm in thickness is applied uniformly with resin with which a TiO2 diffusing body is mixed, thereby obtaining the light duiffusing board which gas a spectral transmission factor of 70 to 75% against visible light of 450 to 700nm, spectral reflection factor of 25 to 30%. and flat characteristics. In order to make characteristics of this excellent, dyes with neutral characteristics are mixecd by 1%, thereby adjusting those characteristics to a fixed value.
