In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.

  As shown in FIGS. 1 to 3, the first embodiment of the ceiling light according to the present invention includes a heat dissipation base 10, a light emitting module 20, a mounting member 30, a plurality of washers, a cap 50, and a ring 60. Have

  The heat dissipation base 10 has a disk shape, a disk body 101 is provided at the center, an upper edge portion 11 is provided at an upper portion, and a lower edge portion 12 is provided at a bottom portion, and the upper edge portion 11 and the lower edge portion of the disk body 101 are provided. A plurality of fins 13 are provided in a radial manner with a space between the upper and lower edges 12, a through hole is formed in the center of the disk body 101, and the upper edge portion 11 is an inner peripheral surface of the upper end of the through hole of the disk body 101. The lower edge portion 12 extends downward around the bottom surface of the lower end of the disc body 101, and the fin 13 is provided with a flat horizontal portion 131 that adheres to the disc body 101 on the intermediate bottom surface. The upper end is extended to the upper edge portion 11 and the lower end is bonded to the lower edge portion 12, and the cap 50 is fitted inside the lower edge portion 12 of the bottom surface of the disc body 101 of the heat dissipation base 10. An annular fitting groove for insertion is recessed.

  The light emitting module 20 is attached to a disc body 101 of the heat dissipation base 10 and includes a disc-shaped plate 21 and a plurality of lamps 22 attached to the plate 21. The plate 21 is disc-shaped by a plurality of bolts. It is attached to the heat dissipation base 10 so as to be in contact with the bottom surface of 101. According to this configuration, the heat generated from the lamps 22 can be conducted to the disk body 101 and the fins 13 via the plate 21, and the heat can be quickly released to the outside.

The attachment member 30 is a hollow tube, an upper ring portion 31 is provided at the upper end, a lower ring portion 32 is provided at the lower end, a thread is provided on the outer peripheral surface of the upper ring portion 31, and an outer periphery of the lower ring portion 32 is provided. A flange 33 extends on the surface.
As shown in FIGS. 3 and 4, the outer diameter of the mounting member 30 and the outer diameter of the upper ring portion 31 are smaller than the inner diameter of the upper edge portion 11, and the outer diameter of the flange 33 is larger than the inner diameter of the upper edge portion 11. The attachment member 30 penetrates the through hole of the disk body 101 so that the flange 33 abuts on the upper edge portion 11, and the flange 33 can be screwed to the upper edge portion 11 with a plurality of bolts.

  The plurality of washers are a first washer 41 and a second washer 42. The first washer 41 has the same size as the flange 33, and is attached between the upper edge portion 11 and the flange 33. The two washers 42 have the same size as the cap 50, are positioned in the fitting groove of the disc body 101, and are attached between the disc body 101 and the cap 50.

  The cap 50 has translucency and is fitted in the fitting groove of the upper edge portion 11. On the other hand, the ring 60 has an annular shape and the bottom surface of the heat radiating base 10 by bolts so as to sandwich the cap 50. Attached to.

  As shown in FIGS. 5 and 6, when attaching the attachment member 30 to the heat radiating base 10, first, the first washer 41 is positioned on the bottom surface of the upper edge portion 11, and the attachment member 30 penetrates the heat radiating base 10 from below. The upper edge 11 and the flange 33 are fixed from the upper side of the heat radiating base 10 by fixing the upper edge portion 11 of the flange 33 by screwing a plurality of bolts with the upper surface of the flange 33 contacting the first washer 41. The member 30 is firmly attached to the heat dissipation base 10.

  On the other hand, when attaching the light emitting module 20, a wire (not shown) of the light emitting module 20 can be wired inside the attachment member 30. Further, a connector 70 is attached to the upper ring portion 31 of the attachment member 30, and a screw thread is formed on the inner peripheral surface of the connector 70 so as to be screwed with the screw thread of the upper ring portion 31. Is connected to an external power source to provide power to the light emitting module 20.

As shown in FIG. 7, the second embodiment of the ceiling light according to the present invention is almost the same as the first embodiment, but the lower edge 12 of the heat dissipation base 10 is different.
That is, the lower edge portion 12 in the present embodiment extends downward from the periphery of the bottom surface of the disk body 101, and an extending wall 121 deeper than the cap 50 and the ring 60 is provided on the inner peripheral surface thereof. That is, the cap 50 and the ring 60 are installed inside the lower edge portion 12 and attached to the bottom surface of the upper edge portion 11 so as to be covered by the extending wall 121. As described above, since the extending wall 121 of the lower edge portion 12 is provided around the cap 50, it is possible to prevent an impact on the cap 50 during the transporting and attaching process, and the cap 50 in this embodiment is an optical lens. Therefore, when the light from the lamp 22 of the light emitting module 20 passes through this optical lens, the optical characteristics of the lens can be exhibited.

  As shown in FIG. 8, when the ceiling light according to the present invention is attached to the ceiling, it may be attached to the same plane as the ceiling 80 so that the lower edge 12 of the heat dissipation base 10 protrudes slightly. Heat generated from the lamp 22 of the light emitting module 20 can be released in the direction of the arrow through the fins 13 of the heat dissipation base 10.

  Further, as shown in FIG. 9, when the ceiling light according to the present invention is attached to the ceiling, the attachment member 30 may be attached to the ceiling 80 so as to be adjusted to an appropriate height and the ceiling light is suspended. Therefore, the heat generated from the lamp 22 of the light emitting module 20 can be released in the direction of the arrow through the fins 13 of the heat dissipation base 10.
