With the vigorous development of museum industry in China, more and more museum exhibitions put forward higher requirements for professional museum lighting technology and products. In museum lighting design, we should uphold the concept of "safety", "revivification" and "comfort", and apply more modern optics, electronics and intelligent technology. In the basic principle of better protection of cultural relics, through the rational use of light and shadow changes, we can create a living, vibrant, realistic and overall optimized lighting effect to present and revivify the historical and cultural details and artistic attainments of the exhibits, and provide a comfortable and high-quality environment for viewers to experience the sights. Good lighting makes the cultural relics in the museum alive.
