How to choose lighting in exhibition design and construction.

In the design and construction of exhibitions, designers generally use integral lighting or mixed lighting. In the form of lighting, exhibition design and construction are similar to room decoration, which are basically divided into three kinds of lighting: centralized light source, auxiliary light source and general light source, which are indispensable and should be used alternately. The light brightness ratio is about 5:3: 1. Centralized light source, the light of centralized light source is direct light, which illuminates a limited area with concentrated direct light, so that visitors can see the exhibits on display more clearly. The shape of the lampshade and the position of the lamp determine the size of the light beam. Therefore, direct-lit lamps are usually equipped with a cover or cooling holes. Moreover, the lampshade is an opaque lamp, and spotlights, track lights and work lights are all common in exhibition construction. Auxiliary light source, centralized light source is very strong. If the eyes are in this environment for a long time, it is easy to feel tired. Therefore, auxiliary light sources are needed in the exhibition construction to make the eyes of staff and visitors feel comfortable. The lighting of the auxiliary light source belongs to diffuse light, and the light it spreads to all corners of the booth is the same. Generally speaking, a lamp with scattered light uses direct light.

Lighting source, usually located on the ceiling of the exhibition hall, is a floodlight source. It is usually the main light of the whole exhibition hall, also called background light. It can raise the indoor light source to a certain brightness and provide the same light for the whole exhibition hall, so there will be no obvious shadow, and there is no serious contrast between the place where the light shines and the place where it does not. But because it must be used with other light. So it shouldn't be very bright. Compared with other light sources in the home, it has the lowest brightness. In short, this set of "5: 3: 1 golden rule of light intensity", the so-called "5", refers to the spotlight with the strongest brightness, such as a projection lamp. "3" refers to the auxiliary light source that gives people a soft feeling. "1" is the most basic lighting source in the whole exhibition hall.
