<p>PURPOSE:To diversify the performance by light by forming a covering from a reflex shade and a transparent part in such a way as surrounding a photo- source, and revolving this covering. CONSTITUTION:A fluorescent lamp 4 in the form of straight tube is lighted by remote control, etc., and a motor 14a is started, and now a covering 16 consisting of a reflex shade 12 and a cover 13 rotate as a signal body in the direction of either the solid or broken line in the attached illustration round the fluorescent lamp 4. With this motion the light changes its direction while casting the beam to a certain side, wherein stepless cast direction is provided by stopping the motor in a certain cast direction as desired. Thereby the cast direction as desired can be changed simply without restriction of the cast direction, and the desired illumination effect can be accomplished easily.</p> |
