공항 외곽 보안시스템의 적정운영을 위한 조명설계

Abstract

Security lighting is installed to enhance the security of people and property. To achieve this objective, it is designed to allow guards to search a large area, either by direct visual surveillance or, indirectly, by closed-circuit television(CCTV) surveillance. The basic principles of security lighting is to provide enough light over the secure area so that anyone moving in or around it can be seen easily. Most CCTV camera manufacturers specify a minimum illuminance needed for their cameras to produce a clear picture. These illuminances are usually given for sodium lamp, and proper illuminance will be required for LED light source. The designer of area lighting should consider a choice of the number of poles, the number of luminaires attached to each pole, the wattage and type of lamp to be used and the mounting height of the luminaires. This paper describes illuminance analysis for adaptable operation of fence security systems through the actual measurement of illuminance by mock-up, and illuminance design to obtain proper illuminance value to keep brightness able to confirm objects considering characteristics of CCTV monitor by simulation.
