Museums play the function of protecting and displaying cultural and natural heritage, carrying out social education and providing scientific research, and have become an integral and important part of people's social life and spiritual culture. On the one hand, we must consider how to provide content-rich exhibitions for the audience in a good visual light environment, on the other hand, we must consider how to more effectively protect the exhibits inside the museum display cases and minimize the damage of light radiation to cultural relics. Therefore, the use of museum display case lights and lanterns has become the museum lighting design, museum lighting design is facing an important issue. According to the rich experience accumulated by Lianyi Display, the museum applied to the lighting is mainly divided into the following three categories.

1. Environmental lighting system: is an important part of the museum exhibition hall environment design, environmental lighting to facilitate the safety of human activities and comfortable viewing atmosphere, can make the audience free and safe walking in the many museum display cases, and in the background of environmental lighting can let the audience soothe and relax to visit the exhibits. In people's lives, light is not only the condition of indoor lighting, but also is the expression of space form, to create the basic elements of the environment atmosphere. Most of the museum exhibition hall ceilings are installed with embedded LED ceiling lights, which will not destroy the perfect unity of the ceiling art because of the setting of the lamps. Its biggest feature is that it can maintain the overall unity and perfection of the architectural decoration, with the structural advantage of using light sources hidden inside the architectural decoration, LED light sources are not exposed and do not stimulate the eye skin.

2. The focus of the lighting system: also known as "task lighting", it is a directional lighting, providing lighting suitable for completion of special activities, such as reading, writing, doing games or craft labor. It creates a bright spot that draws our attention, tells us what to look at, or sets our point of view on an important element of the space or the center of activity. Inside museum pavilions, LED track lighting is generally used as focal point lighting to guide visitors to move their eyes and focus to the various exhibits displayed in the museum's exhibit cases.

3. The atmosphere of the lighting system: museum display cases inside the atmosphere of the lighting is the most direct impact on the exhibits of light, ultra-high color rendering index can make the exhibits of color restoration pure, saturated, transparent and refreshing, so that museum exhibits of cultural relics and art exhibits more pleasing to the eye, reproduce the history and art of the bright, comprehensive enhance the display effect of art. This type of lamps and lanterns generally use LED panel lights or LED spotlights, but also some applications to fiber optic lighting.

To sum up, as one of the important elements of the museum scene, the use of museum display case lighting and lighting applications should be highly compatible with the modern museum architectural style tone, in the process of displaying the theme to be integrated with the architectural space.
