Abstract

LED, is one of the major next generation lamps that, is currently used as a point light source and a surface light source. However, the absence of lighting continuity and hot-spot, which is the biggest shortcoming of LEDs, hindered the production of painting sensation and emotional (or dimensional) lighting of high-end images. Therefore, this work aims to expand and develop the application of future LEDs by supplementing the disadvantages of the current LEDs and presenting their alternatives. The concept and structure of the line light source (LLS), the possible commercialization of the light guide film (LGF), and the LGF applications are proposed by introducing a new conceptual light source using LGF instead of the existing point light source and surface light source. If the basic light performance and reliability are met by LLS, it can be applied for automotive exterior, interior lamp, and building indoor interior.
