Specifically, it is configured to be easily and reliably connected to and disconnected from the power line embedded in the ceiling or wall of the building, and relates to a power connection device for a lighting lamp for easy connection or repair of the light source or the replacement of the light source. will be.

The lighting is installed inside and outside the building to irradiate light to a desired space or point. In particular, the lighting lamps applied to buildings in recent years are mainly embedded in the rear of the ceiling or wall to make the interior space more beautiful to obtain an excellent interior interior effect.

The conventional configuration of such a lamp is electrically connected to a case which is embedded in a ceiling or a wall and is open to the space to which light is to be irradiated, a light source mounted on the inside of the case and a light source for irradiating light, and a power line embedded in the ceiling or a wall. It consists of connecting wires for connection.

In this case, a general fluorescent lamp, a halogen lamp, etc. may be used as the light source, but a light-emitting diode (LED) that emits light with a variety of colors with low electricity consumption is applied. In particular, in order to implement a light source by the LED, a plurality of LEDs are mounted on a printed circuit board, and various electric and electronic devices for converting external power into driving power of the LED are mounted on the printed circuit board.
