APPARATUS FOR ILLUMINATING WIND DIRECTION AND WIND VELOCITY INDICATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for illuminating a dial with a stable light quantity for a long period.

SOLUTION: An acrylic plate is arranged below the dial in which wind direction and wind velocity scales are displayed. A light diffusing and reflecting surface is formed in the bottom surface of the acrylic plate. Light emitting resin rods are arranged at both opposite end surfaces of the acrylic plate.
