This invention refers to a high efficient fluorescent light emission structure, having a large emissive surface, using an electric discharge inside a low pressure noble gases and mercury enclosure. and application of this structure to produce fluorescent lamps for domestic, industrial and public lighting or for LCD screens any shape or size. The problem to be solved: to enhance the efficiency of the light structures; Solution : is done by the small cross-section of the electric discharge and the great surface of the exposed fluorescent material. The light emitting structure uses as electric discharging space the vacuumed, communicative pores, holes and interstices among a grained, glassy, transparent layer coated with/or containing fluorescent material inside an air-tide enclosure sealed between thin, glassy, transparent sheets covered with/ or containing fluorescent material. The thickness of the porous, grained layer is kept by some protuberances, ribs, nervures or undulations of the external sheets or by the porous, grained middle layer itself. A fluorescent lamp using such a structure is made by external glass (12) sheets, having some (13) protuberances or nervures, coated with/or containing fluorescent (14) material, sealing the vacuumed, porous, middle (15) layer made by glass fibers or grains coated with/or containing fluorescent material Some cold (16) electrodes are made by wire, tin or vacuum deposed metal. A reflective (20) layer.is deposed on the back of the rear sheet.
