The utility model discloses a porous light guide assembly which comprises a plate-shaped assembly body, the plate-shaped assembly body is a transparent light guide plate, a plurality of key installation holes are formed in the transparent light guide plate, and optical incident planes are arranged on the outer walls of the upper side and the lower side of the transparent light guide plate in an inward concave mode. The light of the optical incident surface is directly irradiated by the transparent light guide plate and is reflected and scattered by the key mounting hole, so that the key mounting hole uniformly emits light. The porous light guide assembly has the advantages of being good in light uniformity, low in manufacturing cost and long in standby time. 本实用新型公开了一种多孔导光组件，包括板状组件本体，所述板状组件本体为透明导光板，所述透明导光板内置有若干按键安装孔，所述透明导光板的上下两侧外壁均内凹式设有光学入射面，光学入射面的光线通过透明导光板的直射和按键安装孔的反射、散射实现按键安装孔的均匀发光。本实用新型多孔导光组件具有光线均匀性好、制造成本低和待机时间长的特点。
