Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device in which various components are attached to a ceramic body.

In general, articles made of ceramic have the disadvantage that although the dimensional accuracy of the outer surface can be determined, the dimensional accuracy of the inner surface tends to vary.

Therefore, when a chassis or the like is mounted on the inner surface, it is subject to the influence of such variations, resulting in significant drawbacks in that the chassis may be tilted or the mounting height may vary.

The present invention fundamentally eliminates this drawback, and is intended to attach a chassis positioned on the inner surface of a ceramic body using the outer surface of the body as a reference plane.

Hereinafter, the present invention will be explained based on examples.

In the drawings, reference numeral 1 denotes a box-shaped body made of earthenware, with a surrounding window hole 2 formed on the top surface and an open bottom surface.

Reference numeral 3 designates a through hole for a knob 40 for operating a blinking switch, which will be described later.

Note that the mounting window hole 2 is formed in a circular recess 5 on the top surface.

Reference numeral 6 denotes a socket cover made of gold resin, which has a substantially circular shape, and is attached so that the lower surface of a flange 7 formed around the periphery is in contact with the outer surface of the peripheral edge 8 of the mounting window hole 2, and a socket through hole is formed in the center. 9 is formed.

The socket cover 6 is installed using the screw hole 10 provided in the recess 5.
．． This is accomplished by screwing screws 11 and 11' passing through 10' from below to the bottom of the socket cover 6.

Reference numeral 12 denotes a chassis made of synthetic resin located on the surface of the main body 1, which has a substantially cylindrical shape, has a bottom plate 13 attached to its bottom surface, and has a flashing switch 15 held therein by a fixture 14.

Reference numeral 16 denotes a power cord, which is introduced into the chassis 12.

Two bosses 17 and 17' are formed on the upper surface of the chassis 12, and screws is and is' are passed through from below and screwed into the bosses 19 and 19' on the bottom of the socket cover 6.

Therefore, the chassis 12 is attached to the socket cover 6 via the attachment window hole 2.

A socket 20 is located in the socket through hole 9, and its bottom portion is attached to the top surface of the chassis 12 with screws.

Reference numeral 21 denotes a box-shaped light control body made of ceramic, which has a circumferential convex portion 22 formed on its bottom surface and is placed on the upper surface of the flange portion 7 of the socket cover 6 so as to be rotatable within the concave portion 5.

23 and 23' are circular window holes formed on one side and the top, respectively.

24 is a lamp, which is attached to the socket 20.

The lighting device of the present invention based on the above configuration includes a main body made of ceramic having a mounting window hole formed therein, and a socket through hole formed in the center of the body, which is mounted in contact with the outer surface of the periphery of the mounting window hole. a socket cover, a chassis located on the inner surface of the main body and attached to the socket cover through the mounting window hole, a socket located in the socket through hole and attached to the chassis, and attached to the socket. The chassis was attached to the socket cover, which was attached to the outer surface of the ceramic body, through the window hole, so there was no problem with the inclination of the chassis or variations in the mounting height. Therefore, there is an excellent advantage that there is no tilting or variation in installation height for the sockets installed in this chassis and the lamps installed in this sockets. It also has features that are advantageous when built-in.
