indoor brightness strength regardless of

in household, indoor space by using function different also have different requirements for illumination intensity. Ancient kanyu study puts forward the principle of 'Ming room is dark hall', meaning that the brightness of the space such as sitting room, study, restaurant is better than such as bedroom, kitchen space, and compare this design lighting accords with people's life.
