It relates to a flat lamp using the LED to prevent glare.

Fluorescent lamps or incandescent lamps are commonly used as lamps. However, fluorescent lamps generate less heat and are more efficient than incandescent lamps, and thus, many fluorescent lamps are mainly used for lighting, and most offices use such fluorescent lamps. However, fluorescent lamps have a disadvantage of low illuminance and low energy efficiency, so they have recently used light emitting diodes (hereinafter referred to as "LEDs") as relatively high illumination and lower power consumption than these lamps (hereinafter, "LED lamps"). Is commonly used.

An LED lamp typically includes an LED substrate having a plurality of LEDs installed thereon and a circuit pattern formed thereon for supplying power to the LED, a housing supporting the LED substrate, and a power supply for supplying power to the LED. There are various LED lamps, but among the technologies that can be used to replace fluorescent lamps, it is made in the shape of a circular rod configured to detach the existing fluorescent lamps in the case. Patent Document 1 of the "LED fluorescent lamp using the LED module", Patent Document 2 "LED lighting lamps that can be used in fluorescent lamp sockets having a ballast", and the like, and are constituted in the form of a flat plate include "illumination devices using light emitting diodes" of Patent Document 3, and "SMPS separate type LED luminaires" of Patent Document 4.

However, the conventional LED lamps can lower the power consumption and increase the illuminance. However, in the case of Patent Documents 1 and 2, when replacing the fluorescent lamps installed in the existing office, the LED lamps are formed after blocking the portion where the fluorescent lamps are installed and forming a hole again. Since it must be installed, a lot of time and money was consumed in the work. In addition, in the case of a flat LED lamp may be installed in place of the fluorescent light installed in the existing office, it is also necessary to install or modify the existing fluorescent lamp installation after the installation or to install a separate fixing means again. There were many difficulties.

Moreover, such LED lamps generate a lot of heat in the LEDs and circuits, and there is a problem in that the components are not easily released due to heat, and a single LED substrate is composed of a single LED substrate. If damaged, the whole had to be replaced, so there was a problem that the maintenance was expensive.

In addition, even if the LED substrate is divided into a plurality of configurations, such as Patent Document 4, by installing a power supply for supplying power to each LED substrate, the overall structure is not only complicated, but also requires a lot of manufacturing costs and is heavy and suspended from the ceiling. If it falls by its own weight, it may damage itself or injure another object or person.

In addition, in the conventional flat LED lamps, electric wires connected between the power supply and the LED substrate are connected to the rear surface of the housing, that is, the surface facing the ceiling. There was a problem that occurred, there was a problem that the glare caused by the direct light emitted from the LED.

Since each LED lit when viewed from the outside is displayed in the form of a checkerboard on the diffuser plate 52 so that it cannot be a surface light having roughness when viewed from the outside, the distance between the diffuser plate 52 and the LED substrate 1 is at least 40 mm. It is preferable to hold | maintain abnormally.

In addition, the connecting means for connecting the housing 3 is formed on one side of the cover 5, the connecting means is an elastic connecting plate provided in a portion corresponding to the cover fixing hole 33 formed in the housing ( 53). As shown in FIGS. 1 and 2, the cover fixing hole 33 and the elastic connecting plate 53 are provided in plural, and the elastic connecting plate 53 has an intermediate portion bent outward to form a latching part. And, the engaging portion can be elastically narrowed or unfolded to be fixed to the fixing hole by unfolding in the state fitted in the cover fixing hole (33).

On the other hand, the LED lamp according to the present invention heat-dissipated the housing 3 in order to more quickly and efficiently release the heat generated in the LED and the circuit. In addition, heat dissipation coating was also performed on the back surface of the LED substrate 1 to increase the heat dissipation efficiency of the LED substrate 1 itself.

Various materials or methods may be used as the heat radiation coating. In one embodiment, when the composite binder resin, in which nano-sized inorganic thermal filler particles are highly dispersed in a thermally conductive functional resin, is coated on the LED substrate 1, the heat generated from the LED and the circuit may be reduced. As it is converted into vibration energy, it is released to the outside by the thermal diffusion effect of the thermal conductive functional resin. The inorganic filler is any one of alumina (Al 2 O 3 ), aluminum nitrite (AlN), boron nitride (BN), graphene (graphene), graphene oxide, carbon nanotubes, carbon fiber, silicon carbide, artificial diamond The heat conductive functional resin may be used, such as polycarbonate, polypropylene, siloxane polymer.

In addition, the illumination lamp of the present invention was further provided with a reflection sheet (3a) so that the light generated from the LED is reflected to the front to increase the illuminance. The reflective sheet 3a may be installed on the entire bottom surface of the housing 3, but the vertical front surface of the LED substrate 1 may be installed only on the inclined surface of the edge instead of being installed since the light emitted from the LED is radiated in a straight line. (See Fig. 1)

The flat lamp using the LED according to the present invention configured as described above is already inserted into the fluorescent lamp installation seat formed on the ceiling, and then through the housing to tighten the fixing screw, etc. to fix the structure such as a frame or plate installed on the ceiling cover ( 5) can be installed in combination.
