PURPOSE:To enlarge the moving distance of a spot light, and thereby widen the range of spaces for light installation by providing a cylindrical body furnished with an installation seat which goes up and down along the side wall of a lighting body, for the inside of the lighting body of a down light, and thereby mounting a small sized spot light onto an installation stand which is moved up and down in the inside of the cylindrical body. CONSTITUTION:A down spot light includes a double structural main body composed of lighting body 1 and of a cylindrical body 2, and the cylindrical body 2 is moved up and down along a vertical slide groove 6 provided for the wall of the lighting body via an installation seat 11. At least, paired slide grooves 7 are provided for the side wall of the cylindrical body 2 sliding in the inside of the lighting body 1, and an installation stand 3 on which a small sized spot light 4 is mounted, is slidably moved up and down along the slide grooves 7. The down spot light thus includes the double structural main body composed of the lighting body 1 and of the cylindrical body 2 where sliding motion is duplicated, the depth of the lighting body 1 can thereby be made shallower than that of a former one with respect to the moving direction of the spot light 4, the clown spot light can therefore be made small in size. |
