Research And Design Of Hybrid Illumination System For Indoor Lighting

The topic for the domestic natural light combination lighting system conducted in-depth research, and on this basis, based on non-imaging optics theory and design of a new type of natural light combination of illumination optical system, while based on wireless sensor networks for LED intelligent control, natural light and LED artificial light mixed light interior lighting systems. The system can more adequately based on the use of natural light, lighting control provides constant illumination. The main contents are as follows:(1) The system of domestic natural light, natural light and the associated condenser design. Analysis of the characteristics of natural light and solar elevation angle environment, azimuth calculations, as well as the basic principles of non-imaging optics. For mixed light interior lighting system for the overall design.(2) Design a complete system of natural light received light. Including the design of the plane received light board, the establishment of a condenser model, Trace-pro software simulation to analyze the light collection efficiency, the impact of space and focal point of the incident angle of divergence characteristics. TIR lens design based on free-form surface meshing methods and LED lens. And a coupling element designed to connect the condenser with the spectral separation means between the light guide fiber.(3) Design with LED light control algorithm to achieve the face of constant illumination control. Research and Zigbee wireless sensor network technology, folly understand its technical features and protocol stacks. Select a chip solution, and implement the protocol stack on the Z-stack overall development, data transmission and networking.(4) For the environment of an office, the illumination proposal for natural illumination, LED illumination and hybrid illumination was design used the three optical system above. The proposal was simulated and analyzed via DIAlux and can meet the illumination requirements of the state ’building lightingdesign standard.
