The coupling ring 40 is formed in a ring shape to be coupled to the bottom surface of the seat ring 17 of the main body 10 by screws and is fitted with a diffusion cover 30 in an inner diameter and is projected with a circumferential band A ring body 42 constituted by a plate-like ring is constituted so that the ring flange 41 and the ring body 42 are integrally formed, Shaped ring.

That is, the coupling ring 40 has a ring flange 41 protruding in the direction of the integral upper direction, that is, the bottom face of the main body 10, with an inner diameter penetrating through the center of the coupling ring 40. In the ring flange 41, The outer diameter of the flange 32 of the diffusion cover 30 and the inner surface of the ring flange 41 of the coupling ring 40 are brought into close contact with each other and the outer diameter of the ring body 42 is set to be larger than that of the seat ring 17 To the bottom surface of the main body 10 so as to be in contact with the inner diameter of the main body 10.

A plurality of protrusions are formed on the inner surface of the lower portion of the body 10 so as to extend integrally with the main body 10 and protrude downwardly therefrom. The engaging ring 40 is seated on the inner surface of the body 10 and is screw- And the engagement ring 40 is coupled to the lower inner surface of the body 10 by the projection or the engagement ring 40 is directly coupled to the lower inner surface of the body 10. [

The protrusions are spaced apart from each other by a predetermined distance in the main body 10 and have a low height so that the O ring c is inserted into the concave groove and the tight contact portion 33 of the diffusion cover 30 and the main body 10, Even if the diffusion cover 30 is coupled to the bottom surface of the main body 10 in a state where the O ring c is positioned between the bottom surface of the main body 10 and the O ring c, 10).

The seat ring 17 includes a ring-shaped seating ring 17 protruding integrally from the bottom surface of the main body 10, that is, the inner peripheral edge of the flat surface of the main body 10. The seat ring 17 has a predetermined width And the seat ring 17 is protruded downward, that is, in the direction of the paper surface, when the main body 10 is installed on the ceiling of the room.

The seat ring 17 is used for cleaning water for cleaning the main body 10 in the state where the main body 10 is installed on the ceiling of the room or in an outdoor illumination lamp, Thereby preventing the water from intruding into the main body 10 for the first time.

The O-ring c having a circular cross-section and a ring-like outer shape is placed in the close contact portion 33 of the diffusion cover 30 while the O-ring c is placed in the circular shape of the close contact portion 33 of the diffusion cover 30 The bottom of the O-ring c is brought into close contact with the bottom of the concave groove of the tightening portion 33 and the bottom surface of the main body 10 is brought into close contact with the top of the O-ring c.

The contact portion 33 located in the inner diameter of the seat ring 17 has an O ring c placed in a circular concave groove and an O ring c placed on the bottom surface of the body 10, The ring flange 41 of the coupling ring 40 is placed on the lower surface of the diffusion cover 30 in such a manner that the O ring c, the diffusion cover 30, The diffusion cover 30 and the lower portion of the main body 10 are air-tightly sealed by the O-ring c by screwing the coupling ring 40 and the lower portion of the main body 10 as bolts.

When the coupling ring 40 is screwed to the bottom surface of the main body 10 by the screws, the ring flange 41 of the coupling ring 40 presses the close contact portion 33 of the diffusion cover 30, The O ring c is pressed against the bottom surface of the main body 10 by pressing the O ring c so that the space between the main body 10 and the diffusion cover 30 is sealed and watertight.

The waterproof column 16 is integrally formed at the center of the top surface of the upper surface of the main body 10 and is vertically pierced on the airtight top surface of the airtight upper surface composed of columns of cylindrical, An inlet hole 11 through which the electric wire of the converter 60 is inserted and a screw hole 18 vertically penetrating the inlet hole 11 are formed.

The main body 10 is integrally formed with the upper flat portion and the curved lower portion, and the flat portion or the curved portion is not limited to a circular shape but can be deformed into a rectangular shape or a square shape. Do.

The inflow hole 11 is vertically penetrated through the waterproof strut 16 so that the bottom surface and the upper outer surface of the main body 10 are communicated with each other and the screw hole 18 is spaced apart from the inflow hole 11 at a predetermined interval, And a groove having a certain depth which is formed by female threads and which shares one side with the female thread 11.

The upper end of the waterproof support 16 is provided with an inlet hole 11 and a screw hole 18 penetrating therethrough and a closed protrusion 12-1 protruding in an upward direction integrally, And a watertight packing (b) is placed in the watertight packing seat (12).

The watertight packing (b) is a closed type having a groove (b-1) in cross section and having a concave shape in cross section, and has a plurality of small protrusions the protrusion 12-1 of the waterproof strut 16 is inserted into the groove b-1 of the watertight packing b so that the watertight packing b is sealed in the watertight packing The inner side surface and the outer side surface of the watertight packing b are brought into close contact with the upper surface of the waterproof strut 16

The width of the protrusion 12-1 of the waterproof column 16 is set so that the protrusion 12-1 of the waterproof column 16 can be inserted into the groove b-1 of the watertight packing b, And the protrusion 12-1 of the waterproof strut 16 presses the watertight packing b while the end of the protrusion 12-1 is positioned in the groove b-1 Tightness of the watertight packing b is further ensured so that the small semicircular cross-section projection b-2 on the upper surface of the watertight packing b comes into contact with the bottom of the converter housing 50, that is, the converter seat 52 The airtightness between the converter housing 50, that is, the converter seat 52 and the main body 10, that is, the waterproof support 16, is increased.

If the watertight packing seats 12 are formed in a flat surface, it is difficult to normally place the watertight packing b in the watertight packing seat 12 and even if the converter seat 50 and the body 10 are assembled, Since the packing b can move between the watertight packing seats 12 and the converter seat 50 to cause airtight obstacles, the present invention solves this problem by providing the watertight packing seats 12 on the protrusions 12 -1), and the cross section of the watertight packing (b) was formed as a groove (b-1).
