It is well known that there have been many changes in our daily life as well as our residential culture since the beginning of the spread of lighting.

On the other hand, it is also true that such lighting is not only to illuminate the environment, but also to change the interior decoration, such as to enhance the atmosphere of the room to the fullest.

In particular, as a genre of architectural culture these days, the role of lighting is one of the biggest elements in creating the atmosphere of the interior, and its functions and roles have been expanded to show various lighting that can create the atmosphere of the interior. .

Such lightings are used to convert electrical energy into light energy to identify objects even in dark places, and to create interior decoration or cozy atmosphere in recent years. Such lightings are manufactured in various forms. In the related art, lighting fixtures using incandescent lamps or fluorescent lamps have been mainly used.

The incandescent lamp is inexpensive to manufacture, but a lot of heat is generated in the conversion of electrical energy into light energy, which has recently been refrained from use. Fluorescent lamps have high energy conversion efficiency compared to incandescent lamps, resulting in low power consumption, but many hours of lighting. This is a problem that takes a short lifespan.
