The utility model provides a technical scheme that above-mentioned technical problem adopted does: a side light-emitting panel lamp comprises a frame body, a light source plate, a detachable back plate, reflective paper, a light guide plate and a diffusion plate, wherein the light source plate is annularly fixed on the inner wall of the periphery of the frame body; the lower end edge of the inner wall of the frame body is outwards provided with a check ring which is distributed annularly, the upper side of the check ring is upwards provided with a first limit ring and a second limit ring which are distributed annularly and concentrically, the first limit ring is arranged at the inner side of the second limit ring, the first flexible sealing ring is embedded between the first limit ring and the second limit ring, and the lower plane edge of the diffusion plate is tightly pressed at the upper side of the first flexible sealing ring; the upper end of the frame body is provided with annularly distributed sinking grooves, and the second flexible sealing ring is embedded in the sinking grooves; the edge of the lower plane of the back plate is tightly pressed on the upper side of the second flexible sealing ring, the EVA cushion is arranged between the reflective paper and the back plate, the EVA cushion, the reflective paper, the light guide plate and the diffusion plate are tightly pressed and attached to each other.

Preferably, the inner side edge of the retainer ring is also outwards provided with a limit ring which is distributed in the circumferential direction, and the lower plane of the diffusion plate is attached to the upper end face of the limit ring.

Compared with the prior art, the utility model has the advantages of: the utility model realizes flexible sealing by means of the first flexible sealing ring and the diffusion plate to prevent water from entering the frame body from the diffusion plate, realizes flexible sealing by means of the second flexible sealing ring and the back plate to prevent water from entering the frame body from the back plate, and compresses tightly by means of the EVA cushion pads, can achieve waterproof effect without glue pouring, simplifies production steps, reduces labor cost, effectively avoids scrapping of the light guide plate and the light source plate, and further reduces production cost; in addition, the design of detachable construction for it is comparatively convenient to maintain.
