Description

[0001] EDGE-TYPE LED ILLUMINATION DEVICE [0002]

The present invention relates to an edge type LED lighting apparatus, and more particularly, to an edge type LED lighting apparatus provided on a ceiling to provide surface illumination through an edge type light source (LED) irradiated with a light guide plate.

LED lighting devices which are used for illumination, advertisement, etc. and LED (Light Emitting Diode) as a light source are classified into a direct type and an edge type according to the installation position of a light source.

The direct type is a point light source structure in which the LED array is installed toward the front of the device with almost the same area as the light panel, and the light is transmitted straight through the light panel. Since the light of the LED having a strong directivity enters directly into the sight of the user, And fatigue.

On the contrary, the edge type is a surface light source structure in which a light source is installed at one or more edges of a light panel, and an LED light is incident on a side of a light panel and is diffused and scattered over the entire area. In the light panel, A light guide plate mixed with grooves, prints or sanding irregularities or a light diffusing agent of a set pattern, or a light diffusing film is formed on the entire surface of the light transmitting plate.

Such an edge type LED lighting device uses LED diffuse scattering to convert light from LED to plane light, and can provide advanced light without glare while using LED as a light source, which is favored by modern people suffering from eye fatigue ..

The LED illumination apparatus according to this prior art is configured such that, in the combination of the illumination lamp frames 10, the ends of the preceding illumination lamp frames are cut at an angle of 45 degrees, and the four illumination lamp frames 10 are combined to form a squared- At both ends of the 'A' -shaped corner bracket 70 are fastened to the adjoining luminaire frames 10 at the connecting portions of the luminaire frames 10 to fix the luminaire frames 10.

As shown in FIG. 2, when the illumination lamp frames 10 are fixed by the 'A' shaped corner brackets 70, a clearance G is likely to be generated at an assembly site of the illumination lamp frames 10, There is a problem that the quality of the product deteriorates because light leaks through the light source G.

In addition, since the LED illumination means is not in close contact with the side surface of the light guide plate 30, the light emitted from the LED can not be transmitted to the light guide plate, It has not been possible to provide uniform illumination, and quality problems have arisen, such as darkness at every part or darkness at the edges.

As a first embodiment of the pressing portion, a portion except for a part is cut at a corresponding position of the metal plate 710, and the cut portion is cut in a direction in which the LED module 600 is disposed And a pressing piece 720 formed by protruding.

That is, the pressing piece 720 is formed by cutting the metal plate 710 at regular intervals and protruding in a direction in which the LED module is disposed.

The pushing piece 720, which is the pressing portion of the first embodiment, is formed so as to be inclined in a certain direction, so that when inserting the pushing piece 720 into the LED insertion groove 120, the inclined direction should be visually checked and then inserted will be.

As shown in FIG. 9, as a second embodiment of the pressing portion, the metal plate 710 is cut in parallel at corresponding positions of the metal plate 710, And a pressing protrusion 730 formed so as to protrude in the direction of the protrusion 730.

The pressing protrusion 730 is formed by cutting two portions and protruding an inner portion of the pressing protrusion 730 in a direction in which the LED module is disposed.

The pressing protrusion 730, which is the pressing portion of the second embodiment, is formed by protruding the inner portion convexly, so that the pressing protrusion 730 can be inserted into the LED insertion groove 120 irrespective of the insertion direction.

According to the present invention configured as above, the LED module 600 (not shown) is inserted into the LED insertion groove 120 formed in the longitudinal direction of the unit frame 110 before the illumination frame 100 is formed by coupling the unit frames 110 together. ) Is inserted from one side.

Thereafter, the module pressing member 700 is inserted and positioned at the rear side of the LED module 600. At this time, the module pressing member formed with the pressing piece 720 of the first embodiment inserts while inserting the pressing piece 720 while confirming the oblique direction.

When the module pressing member 700 is inserted into the LED insertion groove 120, the pressing portion (pressing piece, pressing protrusion) presses the rear surface of the substrate of the LED module 600, .

Accordingly, the light irradiated when the LED is emitted is correctly incident on the side surface of the light guide plate 200, and the incident light is uniformly diffused over the entire area of the light guide plate 200, and then the surface illumination is provided.
