Flat lamp for emitting lights to a surface area and liquid crystal display using the same
View Patent ↗A flat lamp for emitting light to a surface area of a liquid crystal display device includes a bottom having a channel uniformly crossing an entire surface of the bottom, an arc-discharging gas is disposed within the channel, a cover disposed upon an upper junction surface of the bottom, the cover is coated with a fluorescent material, and an electric field generating means for generating an electric field, wherein the electric field generating means is placed along opposing lateral sides of the channel.
1. A flat lamp, comprising:
a bottom having a single channel including a plurality of bends uniformly crossing an entire surface thereof;
an arc-discharging gas within the channel;
a cover disposed upon an upper junction surface of the bottom, the cover coated with a fluorescent material; and
an electric field generating means for generating an electric field, wherein the electric field generating means is placed along opposing lateral sides of the channel, wherein the bottom and the cover are round shaped.
2. The flat lamp according to claim 1 , wherein the channel has a volute shape elongated from an open surface along a circumferential surface of the bottom toward a center of the bottom.
3. The flat lamp according to claim 1 , wherein the electric field generating means includes wires.
4. The flat lamp according to claim 3 , wherein grooves of a predetermined depth are formed at both of the opposing lateral sides of the channel.
5. The flat lamp according to claim 1 , wherein the electric field generating means includes at least two films, wherein each of the at least two films is formed upon the opposing lateral sides of the channel.
6. The flat lamp according to claim 1 , wherein the cover is one formed of at least a glass material, a heat-resistant resin, a metal and an oxide.
7. The flat lamp according to claim 1 , wherein the electric field generating means includes a cathode and an anode, a first distance between the cathode and the anode being constant.
