Both top lighting and bottom lighting functions are used. UV-resistant high-quality lamps are used, and the color temperature is 3300K. The relative content of ultraviolet light ≤ 20 μW / LM.
Cultural relics are controlled by exhibits that are particularly sensitive to light(embroidery, painting, paper items, painted pottery(stone), stained leather, animal specimens, etc.) ≤ 50 LX; Photo-sensitive exhibits(oil paintings, egg white paintings, non-stained leather, silver products, dental horns, ivory products, precious stone tools, bamboo and wood products, lacquer Ware, etc.) ≤ 150 LX; Exhibits that are not sensitive to light(other metal products, Stone artifacts, ceramics, rock specimens, glass products, enamel products, enamel, etc.) ≤ 300 LX. A variety of material exhibits in the same display cabinet or composite products, according to the light sensitive to the high grade of material selected illumination.
Set up rotation fine-tuning illuminance system
Using 93xiliefeilipu lighting lamps, it has the function of filtering infrared and ultraviolet rays.
