(a) is an expanded sectional view of the principal part of FIG. 2, (b) is an expanded perspective view which shows the state which is going to engage | insert the LED unit shown to (a) in the ditch | groove for attachment of an illuminating device. It is an expansion perspective view which shows LED lighting apparatus.

  A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a state in which an auxiliary handrail frame 3 is provided on a handrail 2 as viewed from the indoor side. Is equipped with an LED lighting device 8 according to the present invention. This handrail 2 is provided with standing pillars 1 standing at regular intervals along the weir wall S provided at the outdoor end of the veranda passage, and the handrail 2 is hung on the upper ends of these pillars 1. In addition, the lower ends of the adjacent columns 1 and 1 are connected to each other by the lower frame 24, and the vertical beam 26 is latticed in the section 4 formed by the adjacent columns 1, 1, the handrail 2, and the lower frame 24. The auxiliary handrail frame 3 is attached to the support column 1 at a position lower than the handrail 2 over the entire length of the handrail 2 on the indoor side of the handrail 2. It is fixed by a metal fitting 4.

  As can be seen from FIG. 3, the auxiliary handrail frame 3 is made of an aluminum extruded shape, and is formed integrally with the cylindrical main body 5 whose lower side portion is open over the entire length. The lighting device mounting concave groove 7 is formed by the opening 53a of the cylindrical main body 53 and the downward U-shaped U-shaped frame portion 6. The LED lighting device 8 is fitted and fixed in the concave groove 7 for mounting the lighting device.

  The mounting bracket 4 is a substantially N-shaped aluminum mounting bracket as shown in FIGS. 2 and 3 in a side view, and is formed by cutting a substantially N-shaped aluminum extruded cross section into a certain width. As shown in FIG. 2, the lower mounting plate 4a, the intermediate plate 4b extending downward from the upper end of the mounting plate 4a, and the upper extending from the upper end of the intermediate plate 4b. An arcuate engagement portion 4d that engages with the lateral side surface of the cylindrical main body 5 of the auxiliary handrail frame 3 is formed on the upper side of the support plate portion 4c.

  Accordingly, when mounting the LED lighting device 8 on the auxiliary handrail frame 3, in order to fix the auxiliary handrail frame 3 to the column 1 by the mounting bracket 4, for example, the upper side arcuate engagement portion 4d of the mounting bracket 4 is used. Is engaged with a required portion of the lateral side surface of the auxiliary handrail frame 3 (a portion facing the support column 1) and fixed with screws 27, and each attachment is performed with the auxiliary handrail frame 3 held at a predetermined height. The lower mounting plate portion 4a of the metal fitting 4 is fixed to a required height position on the indoor side surface of each support column 1 with a screw 28.

  After the auxiliary handrail frame 3 is fixed at a predetermined position on the indoor side of the handrail 2 as described above, the LED illumination device 8 is moved from the state shown in FIG. 3 to the illumination device for the auxiliary handrail frame 3.

A connecting wall portion 17 that connects the sides, and a pair of fitting recesses 18 and 19 that are formed opposite to each other so that both end portions of the LED substrate 11 are fitted to both side end portions on the lower surface side of the connecting wall portion 17; The engaging recesses 20 and 21 are provided projecting outward at the upper end portions of the side wall portions 15 and 16, respectively, and provided at the back of the opposing wall surfaces 7a and 7b of the recessed groove 7 for mounting the lighting device. The LED board 11 is fitted and held between the lower surface of the connecting wall portion 17 and the pair of fitting recesses 18 and 19 on both sides. LED 10 mounted on the lower surface side of 11 is lowered from between the pair of fitting recesses 18 and 19 on both sides. So that the light can be emitted towards. As shown in FIG. 4 (b), both side wall portions 15 and 16 have opposite engagement wall portions 23 and 23 formed on the upper end portion thereof and an outer wall width Wa facing the concave wall 7 for mounting the lighting device. It is formed so as to be slightly larger than the inner width Wb of 7a and 7b.

  In order to assemble the LED lighting device 8 as an LED unit, for example, two LEDs 10 (see FIG. 5) and one resistor (not shown) are mounted at a predetermined position on the surface side of each LED substrate 11, It connects with the wiring (illustration omitted) printed on the back surface side of the board | substrate 11. FIG. Then, in a state where the main body case 12 is repeatedly reversed as shown in FIG. 4, from the one end side of the main body case 12, the required number of LED boards 11. The connection wiring 12 is inserted and fitted between the fitting recesses 18 and 19, and these LED substrates 11 are positioned at predetermined intervals as shown in the figure and escaped to the back side of the connecting wall portion 17. Are electrically connected to each other. Further, as shown in FIG. 5, a male terminal 13 and a female terminal 14 of a joint connector are attached to both ends of the connection wiring 12, respectively. Further, as shown in FIG. 4A, the sealing material 29 is filled with the LED substrate 11 on the lower side of the connecting wall portion 17 of the main body case 9 on which the LED substrate 11 is disposed. It is loaded so that only its surface is exposed downward, and is waterproofed. As the sealing material 29, a liquid or semi-liquid curable silicone resin or the like is used. When this curable silicon resin is used, the sealing material 29 can also be used as a holding member for fixing the LED substrate 11 to the lower side of the connecting wall portion 17.

  The LED lighting device 8 assembled in the unit as described above is formed to have a length corresponding to the pitch between adjacent columns 1 and 1 of the handrail shown in FIG. Are inserted into the lighting device mounting groove 7 on the lower surface side of the auxiliary handrail 3 sequentially from one end side of the groove 7 in the state shown in FIG. It is attached so that the end faces of the main body case 9 are in contact with each other in the illuminating device attaching groove 7 over the entire length of the handrail 3. At the time of this attachment, each LED lighting device 8 has a male terminal 13 and a female terminal 14 of a joint connector as shown in FIG. 13 and the female terminal 14 are electrically connected to each other by being concavo-convexly fitted, and a series of LED illuminating devices 8 across the illuminating device mounting groove 7 formed in the entire length of the auxiliary handrail 3. • Install continuously without interruption.
