Zusammenfassung:	The utility model relates to an improved structure of a baffle-board, which is provided with at least an arc-shaped board sheet as a main body. A recess is formed in board sheet close to the central position to allow a light source to be placed; the recess is provided with a bottom part and inclination parts on two sides of the bottom parts; the board sheet is provided with the inclination parts and arc-shaped parts extending from two sides of the bottom part; the exterior angle of the included angle of the bottom part and the inclination part is 35 DEG to 40 DEG, so that part of light rays from the light source is reflected through the inclination part to form reflection rays which irradiate the range of irradiation required below the light source, and light concentration is conducted to improve illumination intensity, so as to increase the utilization rate and the efficiency of the light source.
