Patent number: 8692450Abstract: A surface light source apparatus with dual-side emitting light includes at least a cathode wire structure, a transparent anode structure, a fluorescent layer and a low-pressure gas layer. The transparent anode structure is a surface structure, wherein the cathode wire structure and the transparent anode structure are parallel to each other. The fluorescent layer is located between the cathode wire structure and the transparent anode structure. The low-pressure gas layer fills the space between the cathode wire structure and the transparent anode structure and functions to induce the cathode evenly emitting electrons. The electron mean free path of the low-pressure gas layer allows at least a sufficient number of electrons to directly impact the fluorescent layer under an operation voltage.Type: GrantFiled: September 2, 2011Date of Patent: April 8, 2014Assignee: Industrial Technology Research InstituteInventors: Yi-Ping Lin, Shih-Pu Chen, Jung-Yu Li, Lian-Yi Cho
