Abstract：

In　this　paper,　a　new　light-pipe　system　with　a　conic　concentrator　has　been　designed　and　made.　Through　measuring　lighting　performance　of　three　new　systems　in　three　typical　weathers　in　summer,　the　luminous　flux　and　indoor　illumination　distribution　have　been　obtained.　Comparing　with　the　results　of　the　unchanged　light-pipe　in　summer,　it　comes　to　the　conclusion　that　the　lighting　effects　of　the　new　system　are　better　than　that　of　the　original　system.
