Whether it's the dawn of the sun, or the light from firewood, it allows us to orient ourselves and see the vivid colors in the night as it illuminates the darkness. In modern times, the lighting has been significantly improved. We now have the power of electric light to get rid of the dark and invisible world. Lighting can be used not only to enable people to see but also to create different evironments. We can use combinations of light and different colors to enliven areas such as residential living rooms, meeting rooms, commercial areas, etc., creating a special atmosphere. For example, in many restaurant, the dining area are designed with a mix of warm light and romantic colors to create a comfortable dinner atmosphere. Making proper use of lighting can not only make the environment more beautiful and comfortable, but also enhance security. In addition to lighting, adding other auxiliary means to enhance visibility will also make space more secure. In conclusion, lighting is not only a necessary part of human life, but also a kind of art.
