First, an art gallery is analyzed to determine the appropriate color temperature, color rendering index, etc.
Color temperature
The paintings displayed in the art gallery are mainly divided into traditional Chinese painting and oil painting. Because of the style and tone, traditional Chinese painting can use a warm color adjusting temperature of 2700k-3200k; For oil painting, since there is no style and color, the medium color temperature of 4000k-3200k can be used.
Color rendering index
In the art gallery, there are paintings with high requirements for color, so no matter for traditional Chinese painting or oil painting, the color rendering index should use high color rendering lamps with RA greater than 90.
Secondly, it is the control of illumination in the art gallery. In contrast, the ratio of illumination between ambient light ① and display light ② is 1:3 or 1:4. If the illumination of ambient light is 100 lux, the illumination of display light is about 300-400 lux. In terms of uniformity, the ratio of illuminance to illuminance shall not be less than 0.7, and the ratio of super large pictures shall not be less than 0.3.

Ambient light: It is usually only used for lighting in the space, not for lighting the exhibits.
Display light: the light that only illuminates the exhibits, not the space.
The arrangement of ambient light is mostly the ceiling lamps that are hoisted, ceiling mounted or embedded, and the ambient light is mostly the diffuse reflective lamps with large angle; The layout of display light is mostly rail type lamps, including rail type wall washing lamps and rail type spotlights.
Generally speaking, if the floor height is within four meters and the irradiation distance is 2-3 meters, 10W power lamps shall be used; If the floor height is within six meters and the irradiation distance is 4-5 meters, the lamps with a power of about 20W shall be used.
In another case, if the display light is used more frequently, and the reflected light can make the ambient illumination meet the requirements, then the ambient light can not be used.
The installation of lamps shall follow the corresponding principles. The lighting in the art gallery is similar to the lighting of exhibition boards, which can be arranged according to the principle of installing the lighting of exhibition boards. The ambient light is arranged at a distance from the wall, and the installation distance is the floor height multiplied by 0.38.
In addition, the layout of ambient light also needs to pay attention to some special situations. Sometimes the exhibits in the art gallery are mounted. Such exhibits are prone to secondary imaging problems. In case of such problems, the following layout methods can be used.
