1、无锡职业技术学院毕业设计说明书（英文翻译）英文250Whighpressuresodiumlampelectronicballastinductanceballastsandcomparativeanalysisofperformanceandenergy-saving高压钠灯属于高强度气体放电灯，其发展始于1955年High-pressuresodiumlampisahighintensitygasdischargelamp,anditsdevelopmentbeganin1955.现在，高压钠灯寿命高达10000小时，光效高于100lm/W。Now,high-pressure
2、sodiumlamplifeofupto10,000hours,lightefficiencyishigherthan100lm/W.高压钠灯工作时发出金白色光，它具有发光效率高、耗电少、寿命长、透雾能力强等优点。High-pressuresodiumlampworkissuedgoldwhitelight,ithasahighluminousefficiency,lowpowerconsumption,longlife,transparentfogabilityandsoon.广泛用于道路、高速公路、机场、码头、车站、广场、工矿企业、公园等场地照明。Iswidelyusedin
