装置。[Scope of Claim for Utility Model Registration] A light filter that covers the entire lower area of a box-like body with an open bottom of a fluorescent lighting fixture in which a plurality of fluorescent lamps are installed in the upper part, In order to place the transparent plate-like body having the same structure in a direction parallel to the fluorescent lamp, several elongated mounting plates each having a sawtooth-like continuous inclined part approximately the same length as the width of the transparent plate-like body are formed on the upper end side. Both ends of the member are fixed to both walls of the lower side of the box-shaped body so as to be orthogonal to the fluorescent lamp, and each of the inclined parts inclined in a certain direction is provided with a half-shaped member in close contact with the lower surface side. A transparent plate formed of a transparent sheet is placed, a mirror film is formed on the upper surface of the transparent plate at each inclined portion that slopes in the other direction, and the mirror film is partially peeled off. An optical filter for a fluorescent lamp lighting device, characterized in that the processed portion is applied and placed on the entire surface of the open lower area of the box-like body with the sides of the adjacent plate-like bodies brought into close contact with each other. Device.
