摘要:
A phosphor indication device suitable for use as a meter of a vehicle including an indication section having a pattern and characters to be indicated which are printed with at least one ordinary paint and at least one paint containing a phosphor differing in color when it is exposed to light capable of exciting the phosphor to emit light in fluorescence from when it is exposed to ordinary light unable to excite the phosphor to emit light. The pattern and characters of the indication section may be illuminated by a light source capable of exciting the phosphor to emit light in fluorescence and at least one light source emitting ordinary light, so that the colors of the pattern and characters can be varied when they are illuminated by light capable of exciting the phosphor to emit light in fluorescence from when they are exposed to ordinary light to enable indication to be given in a characteristic fashion.
