The base plate 17 is of a size capable of closing the front end surface of the column main body 8b, including the vertical groove 12, exactly, and the coupling piece 18 has a through hole 19 at the inner end thereof, and is located at the upper center of the base plate 17, Further, the mounting piece 20 has a tap hole 21 in the central portion and is formed so as to be entirely positioned in the central portion of the lower side.

In addition to the connecting piece 18 and the mounting piece 20, the waterproof extension portion 22 and the guide piece 23 are formed on the inner surface of the substrate 17. The waterproof extension portion 22 has the same width as the width of the vertical groove 12 in the column main body 8b and a slightly smaller thickness, and the upper surface thereof is formed flush with the upper side of the substrate 17. The guide piece 23 is V-shaped, and is arranged symmetrically at a slightly central portion of the substrate 17.

The eye plate 10 is made of an extruded material of synthetic resin or aluminum alloy, and has a width and thickness equal to the width and depth of the vertical groove 12, and is configured to form a space inside. The translucent plate 11 is a milky white translucent resin plate and is fitted and fixed in a window 24 formed on the lower surface side of the column main body 8b. The luminaire 6 is composed of a fluorescent lamp 25 and other devices such as a ballast 26 necessary for lighting the fluorescent lamp 25, which are mounted on a plate-shaped chassis 27.

The lamp pedestal 7 is an extruded product and has a roof shape having a top plate portion 28 and side plate portions 29 (a, b) connected to both sides thereof in a cross section as shown in FIGS. And the width is slightly larger than the length and width of the entire lighting fixture 6 (FIGS. 1 and 3), and the sliding ribs 30 projecting laterally are integrally formed on the lower portion of the side plate portion 29 (a, b). It is being touched. A coupling bolt 31 is fixed to the central portion of the tip of the lamp base 7 with a screw portion protruding downward.

The illumination lamp 1 is assembled as follows. The pillar main body 8a and the pillar main body 8b are joined together. The lighting fixture 6 mounted on the chassis 27 is mounted inside the lamp pedestal 7 with a plurality of mounting screws 32. That is, the lamp pedestal 7 is arranged on the back surface of the lighting fixture 6, and the lighting fixture 6 is fixed thereto. The connecting bolt 31 at the tip of the lamp pedestal 7 is passed through the through hole 19 of the connecting piece 18 in the cap 9, and the cap nut 33 is attached to the protruding side to connect the cap 9 and the lamp pedestal 7.

The sliding ribs 30 on both sides of the lamp pedestal 7 are fitted into the rail grooves 14 of the guides 15 formed on the inner wall surfaces of the both side walls 13 of the upper strut body 8b so that the lamp pedestal 7 and the lighting fixture 6 can be mounted. Insert the pillar body 8b into the inside from the tip end side. The cap 9 is brought into close contact with the tip surface of the column main body 8b, and the fixing screw 34 is screwed into the tap hole 21 formed in the attachment piece 20 of the cap 9 from the lower surface of the front end of the column main body 8b, and the cap 9 is attached. It is fixed to the pillar body 8b. That is, the lamp pedestal 7 is mounted such that its tip end is connected to the cap 9 and is detachably supported along the guide 15 provided on the inner wall surface of the column 5. The fixing screw 34 is provided with an E ring in this embodiment so that the fixing screw 34 does not fall off from the column main body 8b even if the screw is loosened.

Reference numeral 35 denotes a retaining screw, which is screwed into the rear side of the lamp pedestal 7 from the lower surface side and is fixed so as to project to the rear surface side (FIGS. 1 and 3). Reference numeral 36 is a receiving screw, which is screwed from the back side to the groove bottom of the tip of the vertical groove 12 on the back side of the column main body 8b and is fixed so as to project inside. The escape screw 35 and the receiving screw 36 are located on the same line in the longitudinal direction of the column main body 8b, and are arranged at positions where they collide when the lamp base 7 is moved and printed forward.

Further, the waterproof extension portion 22 of the cap 9 attached to the tip of the column main body 8b enters the vertical groove 12 to cover the front end portion of the vertical groove 12 (FIG. 7), and the guide piece 27 is the waterproof extension portion. It is located below the position corresponding to both sides of 22 and inside the column main body 8b.

The eye plate 10 is attached to the vertical groove 12 of the pillar body 8 (a, b) to complete the pillar 5, and the illumination lamp 1 is completed. The eye plate 10 is for concealing the screws that appear on the back side when the members are joined and for concealing the wiring using the vertical grooves.

With the above configuration, when the fluorescent lamp 25 is replaced or the lighting device 6 is inspected, the fixing screw 34 is loosened and the cap 9 is pulled out from the column main body 8b. Upon connection, the lamp pedestal 7 is pulled out together with the lighting fixture 6 from the column main body 8b, and can be replaced or inspected in a wide environment. After the work, when the lighting fixture 6 is stored in the column main body 8b, the lamp pedestal 7 is pushed inward, the cap 9 is fitted, and the screw 34 for fixing is screwed. The unevenness appearing on the surface of the column 5 is about the head of the fixing screw 34.

If the fixing screw 34 is prevented from falling off by the E-ring as in the embodiment, the screw will not be lost during the work. Further, when the retaining screw 35 and the receiving screw 36 are provided, the lamp pedestal 7 does not fall off from the column main body 8b, and the work is easy.

If the lamp pedestal 7 has a roof shape and is arranged so as to cover the back surface of the lighting fixture 6 as in the embodiment, even if water leaks, it is unlikely that the lighting fixture 6 will fall directly onto the lighting fixture 6. The failure of the lighting fixture 6 can be prevented. The above is an embodiment, and the present invention is not limited to the illustrated specific configuration. The connection structure between the cap 9 and the lamp pedestal 7 and the structure for fixing the cap 9 to the column main body 8b may depend on a reliable engagement means.

The vertical strut body 8a and the upper strut body 8b may have different cross-sectional structures with respect to the internal structure. Of the upper and lower ridges that form the rail groove 14, the guide 15 extends downward and bends upward to prevent condensed water or leaked water that may collect in the rail groove 14 from entering the inside of the lamp pedestal 7. Sometimes
