A method for manufacturing a light controlling structure, generally referred to as a microlens or microlens array. The method including providing a bundle of optically transparent members; cutting the bundle of optically transparent members to form at least one sheet of optically transparent member segments; and heating the at least one end of the at least one sheet of optically transparent member segments to form lens surfaces thereon.

L'invention porte sur un procédé de fabrication d'une structure régulatrice de lumière, appelée généralement mini-lentille ou matrice de mini-lentilles. Le procédé consiste à former un faisceau d'éléments optiquement transparents; découper le faisceau d'éléments optiquement transparent de façon à former au moins une feuille de segments d'éléments optiquement transparents et chauffer au moins l'extrémité d'au moins une feuille de segments optiquement transparents de façon à former sur celle-ci des surfaces de lentilles.
