Abstract
Provided are an apparatus and a method for manufacturing a flat fluorescent lamp. The fluorescent lamp includes a plurality of discharge channels, a gas inlet connecting to the discharge channels, and an exhaust pipe connecting to the gas inlet. The process for manufacturing the fluorescent lamp includes exhausting air from the discharge channels through the exhaust pipe, diffusing a mercury vapor within the discharge channels, blocking a passage between the gas inlet and the most outer channel, and removing the gas inlet and the exhaust pipe.
Claims22
A method for manufacturing a flat fluorescent lamp having a plurality of discharge channels, comprising:
- forming. a first substrate comprising the discharge channels, an gas inlet formed on the same surface as the discharge channels, connecting to the discharge channels, an exhaust pipe connecting to the gas inlet and connection paths connecting the discharge channels each other;
- attaching the first substrate to a second substrate opposing to the fist substrate;
- exhausting gases existing within the discharge channels;
- supplying an inert gas and a mercury vapor into the discharge channels;
- sealing the discharge channels;
- and
- removing the gas inlet and the exhaust pipe.
A flat fluorescent lamp comprising:
- a plurality of discharge channels formed on the same plane;
- a slender passage connecting to each of the discharge channels;
- a groove formed on the same plane as the discharge channels, connecting to one of the most outer discharge channels;
- a sealant sealing the discharge channels from outside by stopping the groove;
- and
- a plurality of electrodes formed on both of ends of the fluorescent lamp.
An apparatus for manufacturing a fluorescent lamp, comprising:
- a furnace;
- a fluorescent lamp, which is put in the furnace, having a plurality of discharge channels, an exhaust pipe through which air is exhausted from the plurality of discharge channels, and an gas inlet through which a gas is supplied within the discharge channels;
- a support unit supporting the fluorescent lamp;
- a mercury vapor getter pipe, which connects to a side of the gas inlet, having a mercury getter containing mercury vapor;
- an exhaust outlet through which air is exhausted from the plurality of discharge channels to keep the plurality of discharge channels in vacuum;
- a heater, which is provided within the furnace, inducing generation of the mercury vapor by heating the mercury vapor getter to supply the mercury vapor within the inside of the discharge channel;
- and
- a transfer unit transferring the support unit from one legion to other legion within the furnace.
