In fact, the lighting of the museum is very particular, unlike the commercial space like a specialty store. Most lamps are not very popular in commercial spaces such as specialty stores. Under the illumination of light, the reflection of the product is beautiful and thorough, and the effect is quite good. However, they are not suitable for museums.
However, the display cases in the museum are all dark. First, to protect cultural relics, there are not only ultraviolet rays, but also infrared rays, which are too strong to affect cultural relics. Second, highlight products, so that exhibits and space have brightness contrast. When the space is in a dark environment, our pupils will be dilated, and at this time we are very sensitive to light.
Many large display cases are cultural relics and the implementation standards are very strict. In the Code for Lighting and Design of Museums, we see the concept that the Lux standard of exhibits that are particularly sensitive to light is less than or equal to 50lx, that is, the light emitted by 50 candles within the range of 1 square meter.
But in reality, most of them will exceed the standard, because it is too dark and the people's viewing experience is extremely poor.
On the one hand, 50Lux takes into account the sensitivity of cultural relics to light. On the other hand, under the illumination of 50Lux, people can't distinguish colors with naked eyes, so 50Lux is a balance between cultural relics protection and appreciation.
This is a common problem in large museums. Most museums in China are dimly lit and the light position is not good. This is a professional problem,
At least distinguish which cultural relics need dark light and which ones don't.
It is obviously unreasonable to use all the dark light across the board.
Of course, some museums are also experimenting with natural light, such as Suzhou Museum in China, Notre Dame Cathedral Museum in Italy and Metropolitan Museum of Art in the United States.

Although natural light has the highest degree of color reduction, the damage to cultural relics caused by a large number of ultraviolet rays it carries is irreversible, and the damage to cultural relics such as paintings and silk is even more devastating.

The reduction of ultraviolet band of led light source is loved by most museums. In the era of more and more advanced technology, if the color rendering of natural light is 100, then the LED has reached 95, and different light sources have their own advantages and disadvantages. Museums can evaluate lighting according to different exhibition hall environments and different cultural relics.
With the development of the times, museums will become brighter and brighter, and exert their greatest value on the premise of protecting cultural relics. In the past, when museums focused on preservation, the lighting emphasized identification, so we could see it clearly. For the purpose of education and promotion, the lighting should meet the purpose of appreciation, observation and research, and the corresponding lighting needs to be improved.
Museums bear the essence of culture and history, and a museum is a history of materialized development. To some extent, understanding the past and present of a place begins with the museum.
