Multimedia Classroom Natural Lighting Glare Research and Lighting Optimization Design

: At present, multimedia teaching has become the main teaching method, but most multimedia classrooms due to natural lighting caused by the glare problem, resulting in classroom lighting effect is not ideal. In order to understand the relationship between glare and natural lighting and provide reference for the improvement of the light environment of multimedia classrooms, this article selects a typical classroom in a university in Henan as the research object. Based on the natural lighting glare index (DGI), the paper studies the influence degree of natural lighting glare of multimedia classrooms, and uses DALI software simulation to dynamically simulate and analyze the improvement of the light environment of multimedia classrooms from the perspective of shading from the side windows of buildings, then obtains the lighting design scheme with the least affected by glare, which provides reference for the lighting design of multimedia classrooms and teaching buildings.
