Abstract:
In a surface light source capable of uniformizing a luminance, a body includes a plurality of partition walls, and a gas passage. The partition walls divide an inner space that has a discharge gas into a plurality of discharge spaces that are isolated from each other. The gas passage is formed on each of the partition walls to provide a discharge gas to each of the discharge spaces. The gas passage is formed to be inclined with respect to a lengthwise direction of the discharge space. An electrode that is disposed on the body supplies the discharge voltage to the discharge gas.
Abstract:
An electric double layer capacitor and a method for manufacturing the same, in which one or more projections are formed on an inner bottom surface of a lower case, which is a concave container made of ceramic, in a the process of sequentially stacking a lower electrode, a separator, and an upper electrode in the lower case and covering the lower case with a sealing plate. It is possible to eliminate the process of injecting a bonding liquid and strongly connect the lower electrode and the upper electrode to the lower case and the sealing plate, respectively, by means of the projections, thus preventing the occurrence of a short circuit and reducing the equivalent series resistance.

The second film may include a second heat-resistant resin. The flexible substrate may further include an intermediate material between the first film and the second film. The intermediate material may be applied to an outer part of the first film and may adhere the first film to the second film.
Abstract:
There is provided a surface light source device comprising: a light source body including a plurality of discharge spaces therein, a first electrode and a second electrode applying a first voltage into the discharge spaces and arranged parallel to each other, and a third electrode applying a second voltage into the discharge spaces and facing the first and second electrodes and arranged in a direction of crossing the first and second electrodes. In accordance with the present invention, the discharge firing voltage and sustain voltage of the surface light source device can be lowered by applying the first and second voltage to the electrodes. Further, it is possible to divisionally drive the surface light source device by sequentially and/or selectively applying a voltage to divided parts of each electrode.
Abstract:
A surface light source device includes a lamp body, a space dividing member, a discharge gas supplying member and a voltage applying part. The lamp body includes a flat shaped space and a fluorescent layer disposed in the flat shaped space to convert an invisible light into a visible light. The space dividing member divides the flat shaped space into a plurality of discharge spaces. The discharge gas supplying member is disposed to pass through the space dividing member and is fixed to the space dividing member, and supplies the discharge spaces with a discharge gas that generates the invisible light. The voltage applying part applies a discharge voltage to the discharge gas. Therefore, the lifetime of the surface light source device generating a planar light is increased, and the luminance of the light becomes uniform so that the display quality of an image is improved.
Abstract:
A surface light source device includes a first substrate, a second substrate and an electrode. The first and second substrate defines a discharge space into which a discharge gas is injected. The electrode applies a voltage to the discharge gas. Any one of the first and second substrates includes a sodalime glass. The sodalime glass includes an ion-exchanging layer containing potassium ions that are ion-exchanged for sodium ions. Since the surface light source device does not have the sodium ions, a discoloring of the surface light source device due to an elution of the sodium ions may be prevented. Further, the sodalime glass may have an enhanced strength.
Abstract:
A surface light source device includes a light source body having an inner space into which a discharge gas is injected, and an electrode for applying a voltage to the discharge gas. The light source body includes partition walls dividing the inner space into a plurality of discharge spaces. The partition walls have a width for suppressing formation of a parasite capacitance through which a current flows therein.
Abstract:
A surface light source device includes a light source body having an internal space into which a discharge gas is injected, and an electrode for applying a voltage to the discharge gas. Partition walls are arranged in the internal space to divide the internal space into a plurality of discharge spaces. To reduce areas of the partition walls, a groove is formed at a side face of each partition wall. Thus, each partition wall has a reduced area so that the partition walls may not act as dark fields of the surface light source device.
