Description

[0001] The present invention relates to a flat type LED lamp assembly,

The present invention relates to a flat LED lamp assembly, and more particularly, to a flat LED lamp assembly capable of improving luminous efficiency while improving workability.

Conventional lighting apparatuses use incandescent lamps or fluorescent lamps as light sources, resulting in low luminous intensity, low uniformity of light transmission, and relatively poor illumination quality. On the other hand, light emitting devices such as light emitting diodes (LEDs) and organic light emitting diodes (OLEDs) are smaller in size than conventional light sources, and can be made extremely thin, Is directly converted to light energy, so power consumption is low and efficiency is very high.

In general, an illumination device using such a light emitting diode has been developed. In general, a flat panel illumination device using a light emitting diode has a light guide plate having a diffusion plate adhered on the bottom, a light emitting diode having a plurality of light emitting diodes The light emitted from the light emitting diode module flows into the side of the light guide plate, and then the light is emitted.

However, since the conventional flat panel lighting assembly is manufactured in a set size, if the mounting holes formed in the ceiling are formed larger than the set size, troubles such as blocking the remaining empty space with the finishing material occur after the flat panel lighting assembly is installed.

Further, in the flat panel lighting assembly, since the side length of the light guide plate and the length of the light emitting device module have a size of several tens of centimeters or more, it is difficult to closely adhere the dozens of light emitting devices placed in the light emitting device module to the side surface of the light pipe. If the light emitting device is not in close contact with the side surface of the light guide plate and a gap is formed at a predetermined interval, the light emitted from the light emitting device is not reflected by the side surface of the light guide plate and flows into the light guide plate. A problem arises.

That is, when the light having passed through the resin molding the LED lamp of the light source unit having a relatively high density enters the low-density air layer, the light is totally reflected at the interface, and the light incident on the light guide plate is reduced. There is a problem that the light efficiency is lowered and the luminance is lowered.
