The Importance of Lighting to Museum Exhibits

Museum exhibits are important cultural relics for studying ancient and modern civilizations, and every detail is of immeasurable value. In order to truly restore the materials, colors, techniques and textures of the exhibits, lighting plays a vital role in museum showcases. Through multi-level, contrasting and orderly lighting configuration, the historical status and artistic value of cultural relics are accurately reproduced, which reflects the core competitiveness of museum curation and is also the core task of museum lighting. However, if the lighting restoration quality is different, the color temperature selection is deviated, and the lighting arrangement is improper, it will cause problems such as color cast, blur, and dimness in the appearance and color of the cultural relics when they are reflected in the eyes of the audience, thus causing a large amount of distortion of the original visual information.

DG believes in museum lighting design that the accurate presentation of lighting is particularly important for displaying the colors and details of exhibits. The following are several important lighting factors that are crucial to the design and lighting quality of museum showcases:

1. High color rendering lighting: 

Museum lighting is a cross-project between technology and history, art, aesthetics, physiology and psychology. The color rendering of light directly affects the hue and saturation of the colors of the exhibits. Lighting with a high color rendering index can more truly restore the original appearance and color of historical relics. In places where colored fabrics and multi-color exhibits are displayed, which require high color discrimination, a light source with a general color rendering index (Ra) of not less than 90 should be used; for places with average color discrimination requirements, a general color rendering index of not less than 90 can be used. A light source of 80% is used as the lighting source. As the requirements for lighting quality increase, the IES-TM30 light quality evaluation method released by the International Illuminating Association can be adopted, and the Fletcher index Rf and color gamut index Rg can be introduced to more comprehensively meet the museum's needs for highly restored displays.

2. Color temperature selection:

In museum lighting design, the presentation of exhibit colors and materials is particularly important. Color temperature directly affects the audience's perception of space and environment, as well as their understanding and recognition of cultural relics and artworks. Cultural relic exhibits of different materials, types, and colors all have the most suitable color temperature. Therefore, when choosing showcase lighting, DG usually chooses adjustable lighting so that different exhibits can choose different lighting. The choice of lighting color temperature needs to be determined based on the characteristics of the exhibits and the theme of the exhibition, rather than simply adopting the color temperature of the environment when the artist was creating. Choosing the right color temperature can shape the atmosphere of the scene and allow the audience to better understand the essence of the exhibits.

3. Precise light distribution from multiple angles: 

Exhibits are arranged in different forms, requiring lighting configurations of different angles and light types to highlight the details of the exhibits and make them lifelike. In museum and art gallery exhibitions, exhibits come in various shapes and sizes, and usually require a variety of angles and light types such as extremely narrow beam, narrow beam, flood light, large flood light, oval flood light, wall wash, etc. When DG chooses museum lighting fixtures, it should flexibly adapt to different exhibits. According to the exhibition needs of different exhibits, use lights from different angles to achieve the best display effect, better outline the details of the exhibits, and make the exhibits lifelike. When lighting vertical wall exhibits, attention should be paid to the matching relationship between the exhibits and the light pattern. Unless specially designed, small exhibits should not use light patterns with too large angles, which will cause the light spot to be too large and the exhibition wall around the exhibit to be too bright, limiting the It enhances the audience's appreciation of the work; for large-scale exhibits, if the beam angle used is too small, the illumination on the frame will be uneven, which will also prevent the audience from fully understanding the essence of the work.

4. Display effect and light projection angle and height: 

The installation position of the lamps directly affects the exhibition effect. Reasonable lighting angle and height can present the best display effect. Different lighting angles (front, side, top, back, 45-degree side) will present different effects. The installation height of the lamp also affects the size and intensity of the light spot projected on the exhibits. Therefore, when arranging lighting, it is necessary to consider the characteristics of the exhibits and choose the appropriate lighting angle and height to achieve the best display effect.

To sum up, the role of lighting in museum showcases is crucial. Through high color rendering lighting, appropriate color temperature selection, multi-angle precise light distribution and appropriate showcase lighting, museums can better display precious cultural relics and allow audiences to fully appreciate the charm of culture and art. As a professional showcase manufacturer, DG Display Showcase is well aware of the importance of museum showcase lighting in the protection and display of cultural relics. During our manufacturing process, every link is carefully designed and strictly controlled to ensure that the quality and functionality of the showcases can best meet customer needs.
