Description

Lighting fixture integrated recessed LED lighting device

The present invention relates to a recessed lighting device installed in the ceiling plate by drilling a hole therein. As the light emitting diode (LED) is used as a light source, the service life is longer and energy consumption is higher than that of a conventional lighting device. The present invention relates to a luminaire integrated recessed LED lighting device. In addition, the present invention improves the structure of the mounting mechanism of the LED lighting apparatus supported around the hole of the ceiling plate, the surface of the ceiling plate (toward the interior side to hide the gap (gap) between the LED lighting device and the hole) ) The size of the finishing cover to be installed on the side can be reduced, and the LED lighting device is easily installed by connecting the finishing cover and the main body with a string, and there is no risk of losing the finishing cover.
