The interior must give people a bright feeling, so the lighting in the living room should be sufficient, and the darkness will affect the career development. The choice of lamps and lanterns on the ceiling of the living room is very important. It is best to use circular chandeliers or ceiling lamps, because circular means to do things satisfactorily. Some living rooms lack sunshine, the interior is dark and unknown, and it is easy to be depressed for a long time. In this case, it is best to hide the fluorescent lamp in the wooden trough on the four sides of the ceiling to supplement the light, so that the light refracts from the ceiling and is soft and not dazzling. The light emitted by fluorescent lamps is closest to sunlight and is most suitable for living rooms lacking natural light.
