Abstract

A flexible and illuminating film structure wherein the flexible and illuminating film structure (10) comprises a flexible single polymer foil (100); a flexible electrically conductive pattern layer (102) with contact areas (104) for components on a first side (106) of the polymer foil (100); at least one cavity (108) which extends though the polymer foil (100) from a second side (110) to the contact areas (104) of the conductive pattern layer (102) on the first side (106) and overlaps with at least one contact area (104); at least one non-organic light emitting diode flip-chip (112) in the at least one cavity (108) and electrically coupled with the contact areas (104); and a first flexible shielding foil (114) layered on the second side (110) of the polymer foil (100).

Description

technical field [0001] The present invention relates to lighting film structures. Background technique [0002] Organic LEDs or OLEDs offer the possibility of producing relatively thin lighting films which can in principle be flexible. However, organic materials require very good protection against ambient oxygen and moisture in order to have a sufficiently long life expectancy from a practical point of view. That's why OLEDs are enclosed between two glass plates, which results in a loss of thinness and flexibility. [0003] During the manufacture of SMD (Surface Mount Device) LEDs (Light Emitting Diodes), components and even bare chips can be bonded on the surface of a polymer substrate for relatively thin lighting that is somewhat flexible structure. The overall thickness of the structure is primarily determined by the sum of the thickness of the LED device and the thickness of the polymer substrate(s). This total thickness leads to an absolute limit on the flexibility...
