Light-transmitting material for illuminated indicator |
(57) A light-transmitting material which is used as an outer surface member of a device
having a light source therein and which is illuminated with light from the light source
when turned on comprises a light-transmitting layer which transmits light and which
is lightly tinted, and a light-shielding layer provided on or adjacent the reverse
surface of the light-transmitting layer. The light-shielding layer is composed of
a light-shielding portion which transmits substantially no light and a light-transmitting
portion which is defined by minute apertures, slits or the like provided at a predetermined
density. Accordingly, when the light source is not turned on, the exterior of the
light-transmitting material appears to be a composite color which is composed of the
color of the light-shielding portion and the color of the light-transmitting layer.
