Abstract

(57) [Summary] [Purpose] The packing for waterproofing the mounting surface of the lighting fixture can also reliably waterproof the lead-in portion of the power supply line. [Structure] Two layers of packings 5 and 5 are arranged between a lighting equipment main body and a mounting surface to which the lighting equipment main body is attached, and a cross-sectional shape between the packings 5 and 5 is a spindle type. The power line 6 is inserted.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drip-proof luminaire, and particularly to a structure of a lead-in portion of a power line.

[0002]

[Prior Art]

 The power line lead-in part of a drip-proof luminaire must have a structure that prevents water droplets from entering the interior along the power line.At this time, use a packing for waterproofing the mounting surface of the luminaire. In order to reduce the number of parts, it is preferable to waterproof the lead-in portion of the power supply line. For this purpose, as shown in FIG. 5, the packing 5 interposed between the lighting fixture 2 and the plate 11 to which the lighting fixture 2 is attached is formed as a hole or slit as shown in FIG. The part 50 is formed, and the power supply line 6 is passed through the insertion part 50.

[0003]

[Problems to be solved by the device]

 In this case, in the case where the insertion portion 50 is formed as a slit, a gap is inevitably formed where the power supply line 6 is inserted, and the insertion portion 50 is a round hole having the same cross-sectional shape as the power supply line 6. Also in the case where the inner diameter of the power supply line 6 must be larger than the outer diameter of the power supply line 6, as in the case where a connector is provided at the tip of the power supply line 6, a gap is created around the power supply line 6. Water will enter the interior of the luminaire through these gaps.

The present invention has been made in view of the above points, and the purpose thereof is to ensure that the lead-in portion of the power supply line is also waterproofed by the packing for waterproofing the mounting surface of the lighting device. The present invention provides a drip-proof lighting device that can be used.

[0005]

[Means for Solving the Problems]

 Thus, the present invention provides a two-layer packing between the luminaire main body and the mounting surface to which the luminaire main body is attached, and a power supply line having a spindle-shaped cross section between the two packings. It is characterized by being inserted. According to the present invention, there is no gap between the power line and the packing.

【Example】

 The present invention will be described in detail below with reference to the illustrated embodiment. The lighting equipment shown here has a ventilation fan installed in a bath room, and as shown in FIGS. A plate 11 having an intake hole 12 is fixed to the ceiling surface by wood screws at the opening of the lower surface of the ceiling-embedded moisture-proof ventilation fan 1, and the lighting device 2 is attached to the lower surface of the plate 11 via a decorative frame 15. Has been installed. The decorative frame 15 here is provided with an opening 16 through which the lighting device 2 is inserted in the center thereof, and a mounting piece 17 that rises upward on the upper surface, and this mounting piece 17 is the lower surface of the plate 11. By being attached with a screw at the center, it is installed below the plate 11 through a space, and the lighting fixture 2 including the lighting fixture main body 20, the light bulb 21, and the globe 22 is mounted on the decorative frame 15. The lighting fixture main body 20 is fixed to the lower surface of the mounting piece 17 by the screw 18 protruding from the lower surface of the mounting piece 17 and the cap nut 23, so that the lighting equipment main body 20 is installed in a state of being inserted into the opening 16. 3 in FIG. 4 is a ceiling material.

The power line 6 drawn out from the ventilation fan 1 and reaching the lighting fixture 2 is a two-layer packing 5 arranged between the upper surface of the lighting fixture body 20 and the lower surface of the mounting piece 17 of the decorative frame 15. , 5, the power supply line 6 has a spindle-shaped cross-section as shown in FIG. Since the packings 5 and 5 follow the outer shape of the power supply line 6, a gap may be formed between the packings 5 and 5 and the power supply line 6. There is nothing.

[0008]

[Effect of the device]

 As described above, in the present invention, the power line lead-in portion is provided between the two layers of packing between the lighting fixture main body and the mounting surface to which the main body is attached, and the cross-sectional shape of the power supply line is a spindle type. Therefore, there is no need for a dedicated packing for the lead-in portion of the power supply line, and there is no gap between the power supply line and the packing due to the cross-sectional shape of the power supply line. There is no ingress of water into the interior.
