The self-study　area is　a　typical　and　mostly-used　space　in　the　library,　therefore　the　light　environment in this　room　directly　affects　students’　learning　efficiency　and　physical　health.　Field　measurements　and　questionnaire　surveys　were　conducted　on　the　light　environment.　The　results　showed　that　the　average　illuminance　of　the　artificial　light　environment　could　not　meet　the　standard,　while　the　average　illuminance　of　the　natural　daylighting　and　mixed　light　environment　far　exceeded　the　standard,　but　the　uniformity　was　poor.　Aiming　at　the　above　problems,　ECOTECT　and　DIALux　were,　respectively,　used　to　study　the　effect　of　different　shading　forms　and　indoor　light　environment　under　different　shading　and　lighting　schemes.　The　results　confirmed　that　among　the　three　shading　methods　of　the　horizontal　device,　vertical　device,　and　sun-shading　blind,　the　effect　of　sun-shading　blind　shading　is　the　best,　and　the　environmental　quality　is　optimal　with　the　uniform　arrangement　of　LED　lamps.　In　addition,　control　recommendations　combining　natural　daylighting　with　artificial　lighting　are　proposed.　©　2020,　Springer　Nature　Singapore　Pte　Ltd.
