The design includes two parts of strong and weak electricity design. Among them, including: power distribution system design, lighting system design, socket system design and lighting protection and grounding system design; weak design include: the design of cable television system, fire fighting system. Lighting design by environmental and efficiency standards, including illumination calculation, the choice of lamps, lighting line, socket wire cross-sectional area and the choice of wire laying method. Socket system design according to the high-grade residential standards. Outlet circuit and lighting back to the routing of different branch power supply socket is installed, the general height is 0.3 meters, air-conditioning outlet height of 1.8 meters, damp places should be equipped with moisture-proof, splash-proof socket type grounding system using TN - C - S system. Lightning protection system design in roof installed lightning and lightning with a combination of air-termination system. Weak current system including fire system, cable TV, telephone communication system, broadband network system. All the design to meet user requirements. For the third type of building lightning protection building. Keywords: lighting design，power supply syst
