Abstract: The curriculum design in illuminating engineering course is one of the important practical teaching parts for building electricity and intelligence major. At present, AutoCAD software is widely used to teach and guide students to complete the illuminating design work in many universities in China. Actually, the lighting space provided by lamps and buildings belongs to three-dimension space, while the electrical lighting construction drawing designed by AutoCAD belongs to two-dimension space, so some lighting characteristic information is missing in lighting design and lighting evaluation. Although students can effectively complete the two-dimensional construction drawings, they cannot intuitively and completely understand on design concept, and even design unreasonable lighting schemes. The introduction of DIALux, a 3D lighting design software, into curriculum engineering course design can form a new course design scheme, so that students can better understand the theoretical knowledge and design process of electrical lighting through designing lighting 3D model. Then they can design a more scientific and reasonable electrical lighting scheme. The new design scheme has been applied in undergraduate students of building electrical and intelligent major and achieved a good teaching effect.
