Abstract

PURPOSE:To realize various designs and a luminous property, and also to efficiently utilize energy by a solar battery, by executing a time display by use of a beam of light of a semiconductor laser. CONSTITUTION:An oscillation part 1 containing a semiconductor for socillating a laser is driven by a step-motor, etc., and is rotated 6 times each per second. As a result, the radial direction of a laser beam is varied in order, and a time display is executed. Furthermore, a beam of light of the external field and a laser beam are collected as electrical energy by a solar battery 2.
