Abstract
Today’s classroom lamps are mostly aluminium-plated grille lamps with plastics, and most of the grids are regular rectangles or squares. According to the standard, the common grid is optimized. By increasing the shading angle of C0°-180° and reducing the shading angle of C90°-270°, it can reduce the glare and achieve the classroom light environment while achieving good light extraction efficiency. In this paper, through mathematical model analysis, I use SOLIDWORKS, tracepro, DIALux for modelling, ray tracing and classroom light environment simulation, it is verified that the grid designed in this paper has a great improvement in glare control compared with common grids.
