Abstract
PURPOSE: To accomplish a simultaneous regulation of the light intensity and the light distribution according to the suspension position of a lamp by varying the light intensity and the opening angle of reflecting plates in linkage with the vertical movemet thereof.
CONSTITUTION: When a lighting device having a reflecting plates 2, a lamp 23 and the like lowered in the suspension position, the number of turns of a string on a reel 7 is reduced, which is detected with a detecting roller 17 so that the roller 17 is pushed up together with a roller support plate 18 and a working plate 21 under the resilency of a coil spring 22. Thereupon, the lower end of the reflecting plates 2 turns inward with an shaft 3 as the fulcrum so that the opening angle of the plates 2 is reduced. Simultaneously, gears 8 and 10 are rotated in linkage with the reel 7 to rotate an intensity regulation control fixed to a shaft on the gear 10 by a specified angle. In this manner, the light intensity thereof can be adjusted.
