Luminous hands and display device with such hands, especially for a timepiece

摘要

The hands consist of a central head (29,35) which rotates about the timepiece axis (15) and the indicating body of the hands (28,34). Light emitted by three diodes (23) located under the dial (10) is directed axially by a cylindrical light guide (18) to the central heads of the hands where reflectors consisting of dihedral cavities (40,41) intensify the lighting to the body of the hands
