Abstract

In an independent control system for object color using spectrum control and a method for independent control of object color using the same, the independent control system includes a lighting device and a control device. The lighting device provides lighting light having a predetermined lighting spectrum to a space where objects are located. The control device controls the lighting spectrum of the lighting light based on the reflection characteristics of each of the objects. In this case, each of the objects in the space is displayed as reflected light of a specific color according to the lighting spectrum of the lighting light.

Description

Independent control system for object color using spectral control and independent control method for object color using the same The present invention relates to an independent object color control system using spectrum control and an independent object color control method using the same. More specifically, it relates to an independent object color control system using spectrum control that independently controls the colors of multiple objects located in a space and displays them to a user by utilizing smart lighting that controls the spectrum in various ways, and an independent object color control method using the same. Recently, driven by diverse consumer needs and technological advancements, technology is being developed that enables products to change color actively. For example, Korean Patent Publication No. 10-2022-0094196 discloses a technology in which a three-dimensional object comprising a light-transmitting substrate and an electrophoretic medium is fabricated and the color of the object changes. In addition, Japanese Registered Patent No. 6319922 discloses a product that changes color by stacking optical structures, and U.S. Published Patent No. 2024-0151995 discloses a technology that changes the color of an object by changing the object's temperature, pressure, voltage, bending, viewing angle, etc. As described above, although technologies for actively varying product colors are being developed in various ways, products developed to date are limited to designing the structure of the product itself or designing the product's inherent characteristics to vary as factors influencing the display color. Accordingly, complex design and manufacturing processes are required to produce color-changing products, and there is a limitation in that it is difficult to change the color of existing products that do not have such a structure. Furthermore, when multiple objects exist in a specific space, there is an increasing need for technology to vary the display colors of each object, but the technology to implement this is still underdeveloped.
