Abstract

PURPOSE: To simplify operation of light intensity regulation by means of a light intensity regulator subject to the hanging position of a lamp.
CONSTITUTION: A lamp device 1 having a shade 2, a suspension position adjuster 8, lamp and the like is suspended from the ceiling through a string 9. When the suspension position of the device 1 is varied, a reel 11 is turned to rotate a intensity regulator 15 by a specified angle through a gear 12 fixed to the reel and a gear 13 on which the regulator 15 is fixed through a shaft 14, whereby a regulation circuit whose output varies with the adjustment in the intensity regulator 15 is operated to adjust the light intensity thereof. The regulation control 15 may be operated according to the extension of an stretchable pantograph suspension link which is provided to the lighting equipment instead of the string 9.
