Abstract: Disclosed is a flat fluorescent lamp, including a back substrate, a front substrate made of a transparent material and mounted on the back substrate through a sealing member disposed therebetween, a plurality of partitions disposed between the back and front substrates to define a discharge channel therebetween, a fluorescent material layer coated along a surface of the discharge channel defined by the partitions, a plurality of electrodes disposed to both the back substrate and the front substrate to cause a dielectric barrier discharge, and a reflective layer to cover the entire back substrate and upper portions of the electrodes disposed to the back substrate.

Abstract: An apparatus for manufacturing a surface light source apparatus in which a light guide pattern portion is formed on a light guide panel includes a pattern design system to which data about a pattern to be formed on the light guide pattern is input. A control system is connected to the pattern design system and transmits a position signal matching a coordinate value of each pattern to be formed on the light guide panel. A header moving portion mechanically moves vertically and horizontally according to the position signal received from the control system. A laser system outputs a laser beam according to a pulse signal synchronized with a movement of the header moving portion. A lens portion allows a laser beam output from the laser system to pass the header moving portion and to be focused on a scanning surface of the light guide panel. A warp prevention unit prevents the light guide panel from warping due to a local heating by the laser beam.
