The US Department of Energy (DOE) recently released a test report on museum solid-state lighting (SSL), which is different from most previous reports based on specific LED luminaire details. The report also includes a library of 46 museums that use LED lighting. Long, director, lighting designer and other professionals surveyed. Although energy efficiency is an important factor in determining the use of solid-state lighting, when evaluating LED lighting, it also considers key factors such as lighting quality and the possibility of damage to artwork.
In the past few years, there have been a lot of reports about the museum's SSL project. With the continuous upgrading of LED products, solid-state lighting technology is clearly more and more suitable for such applications. As early as 2011, the Field Museum in Chicago, USA, actively adopted LED lighting.

Most of the respondents surveyed in the latest report believe that the most important reason for the decision to adopt LED lighting at the exhibition is its low potential damage to works of art. In the early days of white LEDs, there was a concern that powerful point sources and blue energy peaks could damage art works such as oil paintings. The Energy Agency also mentioned a report released by the UK in 2013, which speculated that LED lighting damaged Van Gogh's paintings, but it turned out that in actual tests, in the same color temperature (CCT), LEDs and traditional light sources The blue light contained is the same amount, and the energy consumption of LED release is less than the traditional light source above and below 450nm. Therefore, LED is less harmful to human health than other light sources. In addition, DOE pointed out that local museums have begun to adopt LED lighting, which is the most favorable proof that LED does not harm the goods.
In summary, the cost savings resulting from reduced energy and maintenance costs are the second factor in considering which lighting system to choose, but among other equally important factors, such as light color quality and color quality that matches the work. Ranked first.
When asked if they would use LEDs in the next show, 71% said yes, 32% said they have used LEDs in multiple exhibitions. Respondents said that the public gave high praise to LED lighting, and 97% of museum staff were very optimistic about LED lighting.
Of course, the survey also found that for museums, although LEDs generally outperform other options throughout the application cycle, high upfront costs are still widely used barriers; the bigger problem remains in the application process. Confusing different types of LED lighting products according to the characteristics of the matching, museum staff are also trying to keep up with the pace of LED changes, in addition, poor dimming performance and inconsistency is still a problem.
