Kind Code:
A1
Abstract:
A lighting device is disclosed. The lighting device, according to the present invention, comprises: a light guide plate having a plurality of cutting grooves on the rear surface thereof and having an insertion slot opened toward the rear surface; a lighting unit having a lamp for emitting light to the inside of the light guide plate and inserted into the insertion slot; a cable connected to the lighting unit to supply electricity to the lamp; and a reflective sheet sealing the insertion slot and coupled to the rear surface of the light guide plate, wherein a sealing groove, which extends toward the edge of the light guide plate from the insertion slot and on which the cable is placed, is formed on the light guide plate, a first sealing protrusion, through which the cable passes and blocking the space between the insertion slot and the sealing groove, is coupled to the sealing groove, and the sealing groove and the first sealing protrusion are shielded by the reflective sheet. According to the present invention, relatively effective sealing can be achieved by coupling the first sealing protrusion, through which the cable suitably passes, onto the sealing groove extending from the insertion slot to block the inflow of humidity toward the lighting unit while filling the outside of the first sealing protrusion with silicon.
