  Hereinafter, the method of attaching the LED light source unit 100 shown in FIG. 2 to the main body unit 200 shown in FIG. 4 and setting the LED lighting apparatus 1000 of FIG. 1 will be described. As described above, the folded ends 221 of the leaf spring-like locking pieces 220 provided at the front end and the rear end of the main unit 200 pass through the locking holes 26 of the base 23 of the mounting member 20. And the tip 222 is passed through the locking holes 25 of each side wall 22 of the mounting member 20. Thus, the mounting member 20 is mounted to the main body unit 200 in a state of being accommodated in the recess 211 of the main body unit 200. At this time, the pair of opening edges L in the short direction X of the recess 211 of the main body unit 200 and the projections 35 of the pair of extension regions 33 of the cover member 30 facing the pair of opening edges L are LEDs. In the vertical direction Z with respect to the mounting surface 12 of the mounting substrate 10, they overlap along the longitudinal direction Y. Thereby, as shown in FIG. 1, a plurality of clearances 50 are provided between the pair of opening edge portions L and the region without the convex portion 35 of the extension region 33 of the cover member 30 opposed thereto. Thus, the LED light source unit 100 can be attached to the main body unit 200, and the LED lighting apparatus 1000 shown in FIG. 1 can be set.

You may adjust suitably by bending the stop piece 220 manually.

  Hereinafter, an example of a method of attaching the main body unit 200 of the LED lighting device 1000 of FIG. 1 to a ceiling material will be described. The suspension bolt provided on the ceiling material is passed through the hole (not shown) of the bottom surface 213 of the recess 211 of the main body plate 210 provided in the main body unit 200, and a fixing means such as a nut is screwed into the suspension bolt. Fix to the ceiling material. In this way, the LED lighting apparatus 1000 of FIG. 1 can be attached to the ceiling material.

  In a general LED lighting device, resin is used as a forming material of the cover member, and metal is used as a forming material of the device body. That is, the cover member and the device body are formed of materials having different expansion rates. For this reason, as in the LED lighting device described in Patent Document 1, when the extending portions overlap the opening edge without a gap in the orthogonal direction, the temperature change at lighting or extinguishing causes the fixture main body And the noise by friction generate | occur | produces on the contact surface of the said cover member.

  On the other hand, in the LED lighting apparatus 1000 shown in FIG. 1, as described above, the pair of opening edges L and the convex portions 35 of the extension region 33 of the cover member 30 facing it overlap, so the pair of opening edges A plurality of gaps 50 are provided between the portion L and the extension region 33 not having the convex portion 35. In the LED lighting apparatus 1000, since the gap 50 is provided, it is possible to suppress the sounding generated from the rubbing of the cover member 30 and the main body unit 200 which is generated due to the temperature change at the time of lighting or extinguishing. For this reason, the LED lighting device of the present invention can suppress sounding without being affected by, for example, the difference in materials as described above.

  Further, in the LED lighting apparatus 1000, since the gap 50 is provided, a flow of air is generated between the inside of the recess 211 opening of the main body plate 210 and the outside, and heat generation of the LED 11 and the power supply unit 40 can be alleviated at lighting. . For this reason, the fall of the luminous efficiency of LED11 at the time of high temperature can be improved. Moreover, the problem of failure of the LED 11 or the power supply unit 40 at high temperature can be improved.
