LED ceiling light, etc. {LED ceiling light}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LED ceiling, and more particularly, to an LED ceiling which can be applied to a room with a high ceiling.

In general, in consideration of problems such as high power consumption and short life span of existing light source means, illumination devices using LED as a light source have been developed. When the LED is used as a light source, the lifetime of the lighting device is remarkably increased compared to the conventional light source. Therefore, it is expected that the emission amount of waste can be remarkably reduced to prevent environmental pollution and contribute to energy saving by low power consumption have.

However, in order to use the LED as a light source without glare, the LED must have a structure capable of emitting light, and it is usually mounted on a ceiling for indoor lighting.

Conventionally, ceiling interior lighting has mostly a fluorescent lamp shape or a downlight type structure embedded in a ceiling.

For example, the registered patent 10-1141660 (Registered on Apr. 24, 2012, structure of ceiling embedded type downlight lighting apparatus) shows the structure of downlight installed in the ceiling.

Further, Japanese Patent Application No. 10906088 (June 29, 2009, Fluorescent type LED lighting apparatus) describes an LED illumination similar to a fluorescent lamp.

The feature of the conventional ceiling interior lighting is that the surrounding area of the ceiling is relatively dark because of the structure of diverging light downward.

In the case of large marts, the ceiling must be designed to be relatively high so that the merchandise can be loaded sufficiently, and the ceiling should be evenly distributed without looking dark. This is because lighting actually affects consumers' desire for consumption.

Accordingly, conventional ceiling-mounted indoor lighting may be suitable for use in a home or office with a relatively low ceiling, but is difficult to use in a large-sized high-ceiling market.

Hereinafter, the structure and operation of the LED ceiling according to the preferred embodiment of the present invention will be described in detail.

First, the lighting module unit 300 and the power module unit 200 may be integrally molded.

The lighting module unit 300 may have a cylindrical structure having a light outlet 310 on the bottom surface thereof and a power module unit 200 provided at a central portion of the lighting module unit 300 may communicate with the lighting module unit 300 .

The inner side of the power module 200 is a hexahedral space as viewed from the inside of the lighting module 300 and the upper inner bottom of the lighting module 300 around the inner space of the power module 200 Four substrates 330 are fixedly installed and power is supplied from a power supply unit 210 accommodated in the power module unit 200 to supply power to a plurality of LEDs mounted in the power supply unit 210. [

As described above, if the height of the mounting position of the board 330 and the mounting position of the power supply unit 210 are different from each other, heat conduction between the board 330 and the power supply unit 210 can be minimized.

That is, the heat generated during the operation of the LED is not transmitted to the power supply unit 210, and the heat generated from the power supply unit 210 does not affect the LED, 210) can be prevented from being shortened by heat.

The light emitted from the LED is emitted through the light outlet 310 and the light emitted through the light outlet 310 is emitted through the cover 400.

At this time, the shape of the cover part 400 is an elliptical shape so that 10 to 20% of the total light is distributed to the ceiling, and the remaining light is distributed to the indoor space.
