Title: El-lighting dial
Inventor: HARADA AKINORI
IPC: G04B19/30
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To obtain a color tone that is not affected by mixed color of a luminescent color of an EL element and that of a luminescent substance being added to a dial, by arranging a light-shielding means that is smaller than the dial in front of the dial so that the luminescent range of the EL element can be shielded. SOLUTION: A light-shielding print 20 that is a light-shielding means is formed on the front surface of a dial 10. The light-shielding print 20 is printed in a circle on the front surface of the dial 10 with a light-shielding paint. A character 40 and a scale 41 are formed on the rear surface around the light-shielding print 20 of the dial 10 by a white color. When an EL element 30 emits light, light enters inside from the rear surface of the dial 10 that opposes the emission range of the EL element 30, and is partially transmitted through the dial 10 and emits light with a mixed color between the luminescent color of the EL element 30 and that of a luminescent substance being added to the dial 10 on the front surface of the dial 10.  However, the light-shielding print 20 cannot be transmitted and the printing color of the light- shielding print 20 can be visually recognized as it is from the front surface, thus obtaining an EL lighting dial with a tone color that cannot be affected by the mixed color.
