Claims

[Claims for Utility Model Registration] 1. An appliance body 10 that is directly attached and fixed to the indoor ceiling surface C, and a pair of lamp sockets 27 at both front and rear ends.
A lamp support stay 19 of a certain length equipped with a lamp support stay 19, a straight tube type fluorescent lamp M that is inserted into both sockets 27 and supported, and a fixture while holding the center part of the support stay 19. It consists of a holding frame 20 fixed to the main body 10 from below, and at a position eccentric to either the front or rear from the center of the support stay 19, the support stay 19 and the holding frame 20 are connected to a horizontal fulcrum axis. 31, and the outer surface of the support stay 19 and the holding frame 20
The supporting stay 19 and the holding frame 20 are kept in a point-contact relationship with the inner surface of the support stay 19 by the fulcrum protrusion 34, and at a position eccentric from the center of the support stay 19 to the other side, the support stay 19 and the holding frame 20 are
are assembled using two kinds of operating screw shafts, a vertical vertical adjustment screw shaft 35 and a horizontal horizontal movement adjustment screw shaft 39, and when the vertical adjustment screw shaft 35 is rotated, the support stay 19 The support stay 19 seesaws in the vertical direction around its fulcrum shaft 31, while when the lateral movement adjustment operating screw shaft 39 is rotated, the support stay 19 similarly moves in the left and right lateral directions around its fulcrum convex 34. A ceiling-mounted fluorescent lamp mounting fixture characterized by being set to perform a seesaw motion. 2. The lamp support stay 19 is a hollow straight tube with a rectangular cross section, and its central part is opened to communicate with the device main body 10, while the front and rear ends of the support stay 19 are attached with mounting pieces for a socket cover attached thereto. The holding frame 20 of the support stay 19 is made into a cross-sectional vertical hat type, and a pair of left and right projecting flange pieces 21 are provided.
2. The ceiling-mounted fluorescent lamp mounting fixture according to claim 1, wherein the fixture is fixed to the fixture body from below. 3. The device main body 10 is formed from a conical flange 11 that is directly attached and fixed to the ceiling surface C, and a distribution arm 12 of a constant length that extends integrally and equally in the left and right directions from the center of the bottom surface of the flange 11, and the arm 12 is a hollow straight pipe or a hollow curved pipe with a square cross section, and a plurality of lamp support stays 19 extending from below in a direction perpendicular to the arm 12 are fixed to the lamp support stays 19 in a parallel arrangement by holding frames 20, respectively. 2. The ceiling-mounted type fluorescent lamp mounting fixture according to claim 1, wherein the central portion of each support stay (19) is opened to communicate with the distribution arm (12).
