Abstract

This paper introduces digital wallpaper demonstrator manufacturing based on flexible PET substrate with R2R printed conductive tracks and surface-mounted LEDs assembled on printed substrate on R2R assembly line. Heat management of applied LEDs simulated using Lighting Design Calculator (LDC) and simulated results compared to measurement results. Very good consistency between simulated and characterized results achieved with red Luxeon Color Line 3535L surface-mounted LEDs. In addition, measured junction temperatures of LEDs were about 80°C with 60mA operational driving current when laboratory temperature was 25°C. Such a reasonable low junction temperature for LEDs suggests long operational lifetime for components in wallpaper application.
