放心咯,投影仪投射的光对墙面没有什么影响,如果担心的话,可以去网上买块幕布挂在墙上的。因为现在市场上的投影仪一般都是用光将图像投射到屏幕上的。里面都是高亮度的LED,不是光反射的,不仅对墙面没什么影响,对人的眼睛也不会有很大的影响哦。以前有人担心辐射,其实仅仅由光构成的图像。对人的影响也是可以忽略不计的,放心用吧。@font-face{font-family:"Times New Roman";}@font-face{font-family:"宋体";}@font-face{font-family:"Calibri";}p.MsoNormal{mso-style-name:正文;mso-style-parent:"";margin:0pt;margin-bottom:.0001pt;mso-pagination:none;text-align:justify;text-justify:inter-ideograph;font-family:Calibri;mso-fareast-font-family:宋体;mso-bidi-font-family:'Times New Roman';font-size:10.5000pt;mso-font-kerning:1.0000pt;}span.msoIns{mso-style-type:export-only;mso-style-name:"";text-decoration:underline;text-underline:single;color:blue;}span.msoDel{mso-style-type:export-only;mso-style-name:"";text-decoration:line-through;color:red;}@page{mso-page-border-surround-header:no; mso-page-border-surround-footer:no;}@page Section0{}div.Section0{page:Section0;}展开
