US Patent 10436425 Flexible solid-state illumination devices and method of making the same

A flexible illumination device having a layered sheet-form configuration and including a bottom flexible sheet or mesh of a rigid material, a two-dimensional array of light emitting diodes (LEDs) mounted to the bottom flexible sheet or mesh, and a top flexible sheet formed by an optically transmissive material having a relatively low Young's modulus and hermetically encapsulating the array of LEDs. The LEDs may be further associated with rigid substrates (submounts) attached to the bottom flexible sheet or mesh.
