In the design of the exhibition hall, the artistry and expressiveness of light can be used to render the theme of the display, so that the values and other deep-seated meanings carried by the exhibits can be more deeply recognized by visitors. So how to do a good job in lighting design in the exhibition hall design? Lighting is the most direct way for the audience to enter the art space arranged by the designer.
In general, the lighting design of the exhibition hall is based on the concept of combining daylight and artificial lighting, and the two complement each other. In the lighting design of the exhibition hall, there are three forms of lighting: direct lighting mode, indirect lighting mode, and diffuse lighting mode. These three kinds of lighting are the more commonly used modes in the lighting design of domestic exhibition halls.
The direct illumination mode is mainly to directly irradiate the light on the hypothetical working surface after emitting the light through the lamp, this mode has obvious chiaroscuro, and the light and shadow effect produced by the light has a good setting effect, but the high-intensity light brightness is easy to produce the influence of glare.
The indirect lighting mode is to use the indirect light generated by some shading light sources to irradiate, creating some of the atmosphere required by the exhibition hall and making it more designed.
Diffuse lighting mode is a kind of light that is shot out through the upper mouth of the lampshade and reflected by the flat top, while the light is diffused by a translucent lampshade on both sides, and the light is diffused from the grille at the lower part. The other is to use a shelter to enclose the entire package of the light source to produce diffuse light. This model is gentle and has a gentle gentlemanly demeanor.
Secondly, the lighting in the display process is divided into several forms such as basic lighting, accent lighting, auxiliary lighting, and hierarchical lighting according to its function.
Basic lighting, also known as general lighting or overall lighting, is the basic lighting system that should be found in exhibition spaces or other public spaces, and its function is to allow people to see indoor facilities and passages clearly, and to be able to effectively identify objects.
Accent lighting has a positive effect on the irradiation of key products, thereby enhancing the sense of hierarchy of space; For example, in the important display section of the exhibition hall, you can refer to the sense of space and order created by the lighting in the window design; In the exhibition space, auxiliary light sources are usually needed to enhance the sense of hierarchy of the space and enrich the spatial language, and it is often necessary to use auxiliary lighting (auxiliary side and rear lighting) to cooperate with the key lighting, so that the key exhibits have reflective areas and shadows, so as to highlight them.
Hierarchical lighting is used to distinguish the relationship between the placement of primary and secondary objects. Three-dimensional, multi-angle lighting brings the audience an all-round experience, and the brilliant colors echo the spatial interaction, leaving a deep impression. The use of light sources of different colors in different exhibition areas allows the audience to feel the layering of the exhibition area when entering different exhibition areas, and this three-dimensional lighting also brings all-round spatial interactivity.
Different display themes require different light environments, and designers need to use rich imagination and different lighting effects to shape different themes and achieve different visual effects.
Museum lighting design often uses a combination of basic lighting and local accent lighting. For example, for three-dimensional exhibits, the details are outlined through a combination of directional lighting and diffuse lighting; For some large-scale three-dimensional exhibits, directional lighting and reflective lighting are used to project from both sides, causing different degrees of shadows and highlighting the three-dimensional effect.
Expression of light and color.
Color is inseparable from the light source, and there is no color without light, so the relationship between light and color is also inseparable when designing the exhibition hall.
The warmth and coldness of the light color can set off the theme, create an atmosphere, and have a strong sense of involvement. Therefore, the cultural atmosphere corresponding to different types of exhibition halls, the brightness and temperature of the exhibition hall lighting should also be different.
Generally, light with low color temperature makes people feel pleasant at lower illumination, and overstimulation at high illumination; Light with high color temperature feels dull and dim in low illumination, while pleasant in high illumination. 
For example, most of the museums have low illumination, with dark space materials and warm lighting, bringing the audience into a quiet and comfortable atmosphere.
The science and technology museum should mainly display scientific phenomena and express the sense of science and technology. The light is neutral white, the illumination is moderately high, and the light color is appropriately blue in the area where the sense of science and technology is emphasized.
Different colors and lights can play an incredible role in setting off the atmosphere, and it is necessary to effectively control the color and light of the exhibition to achieve the artistic effect of harmony between color and light.
When the display content is different and the exhibit attributes are different, the lighting design scheme must be changed accordingly so as not to cause the overall visual environment to be out of balance, so as to achieve the best effect.
