Description

A connecting structure for CCFL illuminating apparatus

The present invention relates to a connection structure of a lighting device for a cold cathode fluorescent lamp, and more particularly, to a connection structure of a lighting device for a cold cathode fluorescent lamp that can be easily connected, that is, connected to a plurality of cold cathode fluorescent lamp lighting device. It is about.

In general, Cold Cathode Fluorescent Lamps (CCFLs) are used in backlights of liquid crystal displays and the like, and the demand for them is increasing with the spread of information equipment.

These cold cathode fluorescent lamps are lit on the same principle as the hot cathode fluorescent lamps, which are commonly known to us, while the hot cathode fluorescent lamps are illuminated by electron emission by heat, whereas the cold cathode fluorescent lamps are electrons by the electric field applied to the electrodes. There is an advantage that no heat is generated by lighting as emission.

Therefore, the cold cathode fluorescent lamps have been installed in places where food is liable to deteriorate when not only a liquid crystal display device but also an advertisement device, and heat is applied, thereby preventing food deterioration and improving food advertising effect.

However, since such a conventional cold cathode fluorescent lamp lighting device is manufactured as a single unit of a certain size, when connecting and using a plurality of lighting devices, each of the lighting devices as a separate connection means to be connected after use. Therefore, the work is very cumbersome and uncomfortable, the workability is lowered, and when the connected lighting device is dismantled and reused, there is a problem that the lighting device is damaged due to the difficulty of dismantling and the compatibility is inferior.

Accordingly, the present invention has been devised to solve the problems of the prior art as described above, while easily improving the connection structure of the lighting device for cold cathode fluorescent lamps and unifying the connection structure and simply connecting a plurality of lighting devices By connecting and using, the connection and dismantling of the lighting device is easy, and the workability is improved, and the lighting device is separated without damage due to the simple dismantling operation, thus providing the connection structure of the lighting device for the cold cathode fluorescent lamp. Its purpose is to.
