The Palace Museum is the largest museum in Taipei, Taiwan, and an institution of ancient Chinese art history and Sinology. Reports with TEA (Themed Entertainment Association) and AECOM (Architecture, Engineering, Consulting, Operations and Maintenance) show that the Palace Museum is the sixth-highest museum in the world in 2016.
However, as a professional manufacturer of lighting measuring instruments, we hope to take you on a tour of the Palace Museum from the perspective of viewing historical artifacts, but from the perspective of lighting applications and lighting spectrum.
So this time, we collected nearly 100 pieces of lighting information on various historical relics in the Palace Museum through the illuminated passport-handheld smart spectrometer. This information includes the most famous jade cabbage and meat-shaped stone in the Qing Dynasty, as well as many historic celadon, bronze, calligraphy and ink paintings.
