Museum Lighting and Color Rendering Properties of LED Light Sources(<Special Issue>Museum Lighting Renovation through LEDs)

Abstract

Recently ， the performance ofLED light sources has been irnproved significantly ， therefore those has been used even for museurn lighting where has very severe color rendering properties ． When considering the applicatien of LED light sources to museum lighting ， we have a couple of questions， about whether Ra ， Ri calculated by CIEIJIS color rendering method can properly evaluate color appearance ofobjects illuminated by LED lighting or not ． The new coler rendering valuation method now discussed in CIE is outlined ．

Novel optical applications inspired by the Morpho butterfly’s coloration: technology transfer from reflection to transmission

“…© 2022 The Japan Society of Applied Physics like a skylight for this purpose, requires large equipment related to the building structure, and is also affected by weather conditions, so there is currently no appropriate diffused lighting for many situations. In the end, for the purpose of exhibition in a wide space, efforts are continued to devise light sources, especially LEDs, 47,48) but the aforementioned problems are not yet solved.…”
