In the LED module, a plurality of LEDs for emitting light are mounted on a substrate.

The base 110 may be formed in a rectangular shape having a receiving space formed therein and having one side opened to mount a plurality of the LED modules on the inside. At this time, the shape of the base 110 is not limited to square, but may be formed in various shapes such as a cylindrical shape.

The fixing part 120 is formed along the edge of the base part 110 formed as described above.

The fixing part 120 extends outward along the edge of the base part 110 to form a fixing plate 121 having a predetermined height.

The fixing plate 121 may have a plurality of fixing holes 235 at predetermined intervals and the fixing holes 235 may be formed only in the fixing plate 121 formed in the longitudinal direction.

A fixing spring 200 for supporting and fixing the diffusion plate 300 is installed in the fixing part 120. That is, the fixing spring 200 should be installed on the fixing plate 121 of the fixing part 120 so as to support and fix the diffusion plate 300 closely to the compression plate 141.

The fixing spring 200 may be formed in a leaf spring shape by bending a metal band having a predetermined width.

5, the fixing spring 200 includes a first bending part 210 contacting the fixing plate 121, and a second bending part 210 contacting the first bending part 210 at a predetermined distance from the first bending part 210. In other words, And a third bending part 230 which is positioned between the first bending part 210 and the third bending part 230 and is in contact with the diffusion plate 300, A fourth bend part 240 positioned at a predetermined distance from the second bend part 220 and contacting the diffuser plate 300 and a fourth bend part 240 contacting the first bend part 210 and the second bend part 220, A first elastic connection part 250 for providing an elastic force while connecting the bent part 220 and a second elastic connection part 250 formed symmetrically with respect to the first elastic connection part 250 to form the second bent part 220 and the third bent part 250, 230 and the fourth bent portion 240 are formed symmetrically with respect to the second elastic connecting portion 260 so that the third bent portion 230 and the fourth bent portion 240 are formed symmetrically with respect to the second elastic connecting portion 260, Shot while connecting And may be formed as a third elastic connection portion 270 for providing a sexual force.

A fixing hole 235 is formed in the third bent part 230 to mount the fixing spring 200 on the fixing plate 121.

The fixing hole 235 of the third bent portion 230 is overlapped with the mounting hole 122 of the fixing plate 121 and the fixing spring 200 is fixed to the fixing plate 121 As shown in Fig.

As described above, the fixing spring 200 is installed on the fixing plate 121 to prevent the fixing spring 200 from moving.

A plurality of fixing springs (200) are preferably installed on the fixing plate (121) so that the fixing plate (200) can stack and support the diffusion plate (300).

The prevention part 130 is formed at the edge of the fixing part 120 where the fixing spring 200 is installed.

The prevention part 130 is formed with a blocking plate 131 extending along the edge of the fixing part 120 and formed in a 'C' shape having a predetermined height.

Since the prevention plate 131 is formed in a 'C' shape, it is possible to prevent the fixation spring 200 provided on the fixing plate 121 from being exposed to the outside, thereby improving the appearance of the LED flat panel illumination device, The light from the LED module mounted on the base 110 can be prevented from leaking to the outside, thereby reducing the light loss.

The pressing portion 140 is formed with a pressing plate 141 having a predetermined height extending inward along the edge of the preventing portion 130.

The pressing plate 141 presses the diffusion plate 300 stacked on the fixing spring 200 of the fixing plate 121 to prevent the diffusion plate 300 from being released to the outside.

The inlet part 150 is formed between the prevention part 130 and the pressing part 140 so that the diffusion plate can be positioned between the fixing spring 200 and the compression plate 141. That is, the inlet part 150 is formed as a groove between the preventing part 130 and the pressing part 140 located at one side in the width direction of the housing, so that the diffusion plate 300 is fixed to the fixing spring 200, So that the diffusion plate 300 can be slidably inserted between the pressing plate 141 and the pressing plate 141.

In this case, when the diffusion plate 300 is inserted through the inlet part 150, the fixing spring 200 is moved from the second bent part 220 to the third bent part 300 by the force that the diffusion plate 300 slides, When the diffusion plate 300 is inserted and is positioned between the fixing spring 200 and the compression plate 141, the diffusion plate 300 is pulled up to a maximum extent so that the diffusion plate 300 can be easily inserted. The fixing spring 200 restores the second to third bent portions 230 that have been pulled up to the maximum while the diffusion plate 300 is inserted, So that it can be pressed onto the crimping portion 140.

The housing 100 for the LED flat panel illumination device is manufactured so that the diffusion plate 300 for covering the inside of the base 110 in which the LED module is installed can be fixed to separate the diffusion plate 300 The diffusion plate 300 can be coupled without the need for the material of the diffusion plate 300, so that the material can be reduced and the manufacturing cost can be greatly reduced.

In addition, since the fixing spring 200 is formed on the fixing part 120, the diffusion plate 300 can be easily inserted and fixed, thereby greatly shortening the process time and process time, thereby improving the convenience of the manufacturer .

In addition, since the housing 100 for an LED flat panel lighting device is manufactured in an integrated form, it is possible to prevent dust and foreign matter from entering the inside of the housing, thereby preventing damage to the LED module and occurrence of spark, It is possible to prevent leakage of the light, which is advantageous in greatly improving the merchantability.
