Abstract
A gas injection port structure for a flat fluorescent lap (FFL) is provided. The FFL has a flat lower plate and an upper plate that form a channel therebetween, and at least one gas injection port in communication with the channel. The gas injection port may be formed at a predetermined position on the upper plate so that a height of the gas injection port is level with or lower than a height of the channel. The gas injection port may contain a mercury getter and a sealing material having a passage formed therethrough so that mercury vapor may be injected into the channel and then the channel sealed. The gas injection port minimizes a thickness of the FFL, and improves durability of the FFL.
Claims20
A gas injection structure for a flat fluorescent lamp (FFL), the FFL having a lower plate, an upper plate, and a channel formed therebetween, the structure comprising:
- a gas injection port provided at a first predetermined position on the upper plate;
- a mercury vapor diffusing port provided at a second predetermined position on the upper plate, to a side of the gas injection port;
- a mercury vapor diffusing pipe having an open end and a closed end, the open end being inserted into the mercury vapor diffusing port, the mercury vapor diffusing pipe having a mercury getter provided therein;
- and
- a connection passage that connects the mercury vapor diffusing port to the gas injection port.
An injection structure for a flat fluorescent lamp (FFL), the FFL having a lower plate, an upper plate, and a channel formed therebetween, the structure comprising:
- a first port connected to a first portion of the channel, wherein the first port is in communication with an interior of the channel;
- a first pipe configured to be inserted into the first port such that the first port and the first pipe are aligned along the same central axis;
- and
- sealing material provided in the first port between an end of the first pipe and an entrance into the channel, the sealing material having a passage extending therethrough.
