Therefore, the embodiments described in the specification of the present invention and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. It should be understood that various equivalents and modifications are possible or possible.

Further, the present invention will be described by taking an edge type LED down light as an example. However, the right range in the present invention is not limited to the edge type down light.

The present invention can be applied to the case where the lighting means of the LED down light installed in the existing ceiling 10 is replaced or the housing 10 of the LED down light 100 The LED down light 100 can be fixedly installed through the variable adjustment unit 150 provided on the upper surface of the housing 110, even when the outer diameter and the size do not match.

1, the LED down light 100 according to the present invention includes a housing 110 forming an outer shape and a diffusion plate 140 coupled to a lower end of the housing 110. The outer periphery of the diffusion plate 140, And the support ring 141 which is in contact with the ceiling 10 is engaged and the housing 110 is fitted in the support ring 141.

The LED module 120 is disposed on the inner surface of the housing 110 so that the LED module 120 can be illuminated. Here, various components for supplying power to the LED module 120 have a common structure and configuration, and can be implemented by a person having a conventional skill level, so that the description thereof is omitted in the present invention.

A light guide plate for uniformly irradiating the light emitted from the LED module 120 as a light source to the entire surface of the diffusion plate 140 is provided on the bottom surface of the reflection plate 131, Plate, light guide plate) 130 are installed.

On the other hand, the variable control unit 150, which is a feature of the present invention, is provided on the upper surface of the housing 110 (the upper surface herein means the upper surface in the upward direction in the direction in which the housing is embedded in the embedding hole of the ceiling).

The variable regulator 150 adjusts the variable regulator 150 to correspond to the inner diameter of the embedded hole 11 without restricting the size of the ceiling 10 between the embedded holes 11, So that the LED down light 100 can be coupled as a whole.

It may be most preferable to replace the already constructed LED down light 100 with an LED down light 100 having the same size when replacing the already constructed LED down light 100 with a new LED down light 100. However, The installation can be performed without changing the board of the ceiling 10 already punched by the variable control part 150 of the present invention.

In other words, the outer diameter of a typical LED down light is divided into 4 inches, 4.5 inches, 5 inches, and 6 inches, and the inner diameter of the buried hole formed in the ceiling is also drilled to a size corresponding to each size, The LED down light corresponding to the size was installed and installed.
