FIELD: construction.

SUBSTANCE: invention relates to a light building board for interior finishing. The board contains upper (2) and lower (3) coating layers, and a middle layer (4) disposed between them. The light building board (1) with upper (1a), lower (1b) and multiple narrow (1c) sides contains the upper (2) and lower (3) coating layers, and the middle layer (4) disposed between them. One of the coating layers (2, 3) comprises a woody material, and the middle layer (4) has a cardboard honeycomb structure. On one of the narrow sides (1c) of the part, the end edges (5, 6) of the layers (3,4) located under the upper coating layer (2), at least by certain areas, are dislocated backward relative to the end edge (7) of the upper coating layer (2) towards the middle of the part. The end edges (5, 6) of the layers (3, 4) located under the upper coating layer (2), have respectively a coating (9d), which (9d) is formed by a profile (11) containing integrated light-emitting diodes (10a) and having an overhang (11b) directed towards the middle of the light building board (1), by means of which the profile (11) is fixed in the light building board (1). A polymer is the coating material, and the middle layer (4) doesn't have any spacer.

EFFECT: creation of the light building board, providing highlighting of its environment.
