Illumination Technology Research Of Comprehensive Test Target Lane For Shoot

With people's health principle rising continuously and the optical technique, electric technique and computer technique development, target lane illuminating technique causes more and more extensive research aiming at health, economy energy and environmental protection.The lighting of target lane is function illuminating. It is requested to provide comfortable and pleased vision environment for the shooter. So the design of the vision environment should pay attention to illuminating physical parameter, also need value the interaction that the person feeling and illuminating effect. How degree shooter accepting vision environment and the reciprocity between people and environment are analyzed. From person's eye, this text analyzes some rules of target lane illumination and environment design. Solid foundation is established for the good lighting quality of target lane.The good lighting quality requests not only illumination but also uniformity. It requests to has high color rendering property, color temperature and needs low glare index. By the best illumination experiment during close quarters, it make sure that the best illumination to satisfy the person's vision in the close scope ranges from 1500 lx to 2000 lx. Within the scope of 100m, the atmosphere attenuation has little influence on the visual effect, so the most appropriate illumination ascertains 20001x at 100m. Taking this as basis, the illumination of the target district and excess area is computed respectively at different shot bit. By the best illumination experiment during remote quarters, the accuracy of the result is validated.For making the target district acquire high illumination Uniformity, a kind of wide-angle lamps and lanterns designed, which makes the reflect ray repair with the direct ray and ensures fold illumination distribute symmetrically. Aiming at the problem of the target district requesting higher illumination uniformity, the author puts forward the quasi-sine type particle swarm optimization. QSPSO is applied to design the lighting of target district, and the optimized layout of the lamp-house makes the target district illumination attain 0.9. Because the transitional area of target lane requests low illumination uniformity, the paper adopts DIALux to distribute the light source of the transitional area in order to reduce workload and shorten design time. The equal illumination chart and three-dimensional effect picture of the transitional area are educed. The author carries through a great deal of market investigation, the chose light source satisfies the request of color rendering property and color temperature. After the target lane finished, this paper tested the glare index and brightness distributing with the method that the digital camera with the fish glasses head and software combine. Then the author makes use of a numerical luminometer to measure echo-coefficient of the wall around it and illumination of the target district. All measured results satisfy the design index request.
