In order to improve not only the underground environment but also the indoor environment in urban buildings to a human-friendly environment, and to minimize greenhouse gas emissions by reducing the cost of food materials from rural to urban areas, there is a movement to build plant cultivation in the city center.

In addition, in recent years, the cultivation of the open field is increasing due to extreme weather, such as heavy rains, large typhoons, droughts, etc., and much attention has been focused on an environment in which crops can be reliably grown regardless of climate change.

Therefore, there is a demand for creating an environment in which plants can stably grow even in the face of changing climate changes such as temperature, precipitation, and solar radiation.

In particular, it is urgent to create a light environment in which plants can stably grow even in a space that is absolutely lacking in natural light such as an underground space in a city center. By supplementing with supplementary lighting while using sunlight as a basic technology, technology for controlling the amount of light required for plant growth is required in spaces such as building interior spaces and underground spaces in urban areas.
