Abstract

A flexible lighting element is provided, comprising: a first flexible substrate; first and second conductive elements located on the first flexible substrate; a light-emitting element having a positive contact and a negative contact, the positive and negative contacts both being on a first side of the light-emitting element, the light-emitting element being configured to emit light having a selected narrow range of wavelengths; a first conductive connector electrically connecting the first conductive element to the positive contact; a second conductive connector electrically connecting the second conductive element to the negative contact; a second flexible substrate located adjacent to a second surface of the light-emitting element; and an affixing layer located between the first flexible substrate and the second flexible substrate.
