The objects of cultural heritage, such as paintings, textiles, and jewellery, are damaged by the environmental factors over the me. The restoration of these objects, which aims at revealing the original visual appearance, is highly resource demanding task that is often associated with destructive physical impact. The idea of the Project HeriLED is to investigate the possibility of recreating the original appearance of an damaged object using a lighting device having appropriate spectral power distribution that is comprised of light-emitting diodes (LEDs), when the assumed original visual appearance is available from an undamaged fragment (e.g. back side of the tapestry). The result of the project will be applied knowledge as follows: the mathematical methods, algorithms of colour rendition and image reconstruction, and an innovative lighting device prototype, which allow for checking the colour accuracy of the visual restoration for selected cultural heritage objects. The content of the HeriLED Project is in line with the global trends of the research, development and applications of intelligent solid-state lighting and maintains the excellence of the Lithuanian solid-state lighting school.
