A bottom surface of the main body 10, that is, a portion to which the diffusion cover 20 is coupled is also formed in a circular shape, a square shape, a hexagonal shape, or the like. When the shape of the bottom surface of the LED module inner surface portion 19 and the bottom surface of the main body 10 are the same, for example, the LED module inner surface portion 19 is cylindrical and the bottom surface of the main body 10 is also circular, The shape of the bottom surface of the main body 10 differs from that of the LED module inner surface portion 19. For example, in the case where the LED module inner surface portion 19 is a cylinder and the main body 10 has a circular flange, Is formed of a square so that a rectangular flange is formed at the edge of the cylindrical body, that is, the entrance.

The main body 10 includes an LED module holding portion 19 having an internal space portion a for accommodating the LED module 30 therein and a horizontal flange portion 19 which is integrally projected and bent at the lower portion of the LED module holding portion 19. [ And an outer flange 11 which is integrally protruded and bent at the end of the horizontal flange 12 and spaced apart from the outer surface of the LED module holding portion 19 in the same direction at regular intervals.

The outer flange 11 is protruded and bent in the form of a plate having a constant width integral with the end edge of the horizontal flange 12 and spaced apart from the outer surface of the LED module holding portion 19 in the same direction, 19, and when the LED module receiving portion 19 is circular, it is protruded and bent in the form of a circular strip so as to be parallel to the outer surface of the LED module holding portion 19, and the LED module holding portion 19 In the case of a quadrangle, it is protruded in a rectangular band shape and is configured to be parallel to the outer surface of the LED module inner portion 19.

A cross section formed by the outer surface of the LED module inner surface portion 19, the horizontal flange 12, and the outer flange 11 is formed of a space of a "┛" shape.

The LED module mounting portion 19 is formed at the center of the main body 10 and has an upper surface formed of a closed cylinder, a rectangular tube or a hexahedron to form an internal space, So that the LED module 30 is fixed to the inner space portion a by a screw or the like so that the LED module inner portion 19 embraces the LED module 30.

The outer flange 11 of the main body 10 is cut at the upper side edge of the side surface so as to communicate with spaces formed by the LED module inner portion 19, the horizontal flange 12 and the outer flange 11, And a plurality of air outlets 13 formed in a 'C' shape and spaced apart at a predetermined interval are formed.

The air discharge port 13 discharges the air inside the LED module mounting portion 19 discharged through the air outlet 15 and the air flow port 14 to the outside of the main body 10, As shown in FIG.

The plurality of air outlets 13 are spaced apart from each other by a predetermined distance, the temperature of the air is increased by heat exchange with the heat generated by the LED module 30 through the air outlet 13, .

When the length of the air flow port 14 of the main body 10 of the ceiling-mounted LED lighting apparatus is made to approach the entire length of the LED module holding portion 19, the internal air entering the LED module holding portion 19 flows through the air circulation The amount of internal air that does not contact the LED 31 directly flows out from the lower side of the sphere 14 and the heat exchange with the LED module 30 is insignificant so that the cooling effect is somewhat reduced and the length of the air flow passage 14 is short In the case where the inner surface of the LED module 30 is configured to be higher than the position of the LED module 30 coupled to the inner surface of the LED module inner surface 19, But the discharge of heat-exchanged heated air is not smooth.

The length of the LED module rest portion of the main body of the main body of the ceiling embedded LED lighting device inserted into the ceiling is much longer than the height of the cover flange of the diffusion cover so that the length of the air flow port is not affected by the cover flange, The length of the air flow path of the LED module is different from the length of the LED module according to the length of the LED module in consideration of the discharge of the air entering the LED module and the heat exchange with the LED module, .

The air flow port 14 can be formed in the horizontal direction of the circumference of the LED module holding portion 19 without being configured in the vertical direction of the LED module holding portion 19. In this case, In the case where a plurality of rows of air flow passages are arranged in a row, the position of the lowermost air flow passage nearest to the cover flange 22 is the same as the position of the LED module inner wall portion 19) and about 1/5 of the upper surface of the LED module (19) of the ceiling embedded LED lighting fixture.

[

If a static electricity or a flame is generated in a circuit or a device when the surge absorber or the varistor loses its function, the static electricity or the flame can not be transferred to other parts, and the converter 50 is isolated from the LED module 30 So that the heat of the LED module 30 does not directly affect the converter 50 so that a separate converter holding portion b is formed outside the LED module holding portion 19 of the main body 10, The converter 50 is placed on the tooth portion b so that the converter 50 and the LED module 30 are isolated from each other.
