In general, the lighting device is a kind of electrical and electronic products that convert the electrical energy into light energy and use it in real life.

Such a lighting device is provided with a light source that is a representative example of incandescent and fluorescent lamps, and includes a reflector used to reflect the light emitted from the light source or to improve the illuminance.

Therefore, the light source emits light by supplying electricity in a state of accommodating them in a housing, and the reflecting lamp reflects and irradiates light, thereby effectively illuminating a dark place.

On the other hand, the light source installed in such a lighting device that emits light is mainly used incandescent or fluorescent lamps as described above, but the lifespan is usually about 1.500 ~ 5,000 hours, so the unpleasant light source must be replaced. there was.

This inconvenience is not a problem in places where there are not a lot of lighting devices, but in the case of a large number of lighting devices such as large underground parking lots, when the light source that is at the end of its life is replaced by hand, it is necessary to secure enough professional management personnel. In addition, the occurrence of replacement costs is considerable, which is a big problem.

In order to solve this problem, a Cold Cathode Fluorescent Lamp (CCFL) has been proposed, which is disclosed in KR 20-0240207 2001.10.12. [Document 2] KR 20-0379059 2005.03.17.

Furthermore, KR 10-2005-0116573 2005.12.13 discloses a proposal to use an external electrode fluorescent lamp ("EEFL") as a general light source.

That is, the cold cathode fluorescent lamp according to the [Document 1], [Document 2] or the external electrode fluorescent lamp according to [Document 3] is less heat generation than conventional incandescent lamps or fluorescent lamps and can reduce power consumption by 90% to 20%.
