Title:
METHOD FOR ADJUSTING COLOR TEMPERATURE OF SURFACE LIGHT-EMITTING ILLUMINATION DEVICE AND PRINTING DEVICE FOR PRODUCING SURFACE LIGHT-EMITTING ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/045910
Kind Code:
A1
Abstract:
The present invention enables the easy correction of the color temperature of a surface light-emitting illumination device. A surface light-emitting illumination device is produced comprising: a light guide plate; a light source that radiates light to the inside of the light guide plate; and a light reflecting plate and/or a light diffusion plate disposed in contact with the light guide plate. The color temperature of the light-emitting surface of the produced surface light-emitting illumination device is measured, and when the measured color temperature is not the necessary color temperature, an ink for coloring the light reflecting plate and/or the light diffusion plate is selected, the selected ink is used to perform coloring printing of the light reflecting plate and/or the light diffusion plate by means of an inkjet printer, and the color temperature of the light-emitting surface of the surface light-emitting illumination device using the coloring printed light reflecting plate and/or light diffusion plate is measured. The coloring printing correction of the light reflecting plate and/or the light diffusion plate is repeated until the measured color temperature of the light-emitting surface of the surface light-emitting illumination device is within an allowed range.
