<P>PROBLEM TO BE SOLVED: To provide a paper lantern form lighting equipment of which lamp-shade is easily exchanged having a mating interface which is integrated into the equipment after exchange. <P>SOLUTION: The equipment comprises a mating interface between an axial-side grooved pulley 9 with upper and lower flanges 16 and 17 which construct a base mount part 1 including the lantern and a hole-side ring 8 which constructs a lamp-shade part 2 and they fits with each other. Arc length between the upper flange 16 and each small cut 15 is made into different length. In the inner periphery of the hole-side ring 8, projected pins 19 are prepared in a position facing to the respective cut 15 and curved, wherein the hole-side ring 8 can move upward and is detachable. When the hole-side ring 8 is slidably rotated not so as to face the small cut 15, it cannot move upward and become detachable. The same is true in the case where the small defects exists arbitrarily plural. The lamp-shade 2 can be easily detached from the base mount part 1 and is provides firm connection in an attachment and detachment impossible position. <P>COPYRIGHT: (C)2009,JPO&INPIT |
