Zusammenfassung:	A manufacturing method of a LED (20) having multi-layer optical lenses (30) comprises the following steps: providing a LED wafer (21) (S10); forming an inner protective layer (31) covering the wafer (21) and its lead point (S20); forming an outer protective layer (32) covering the inner protective layer (31) (S30); wherein both the inner and outer protective layer (31,33) are optical gel, and the hardness of the inner protective layer (31) is higher than that of the outer protective layer (32). A LED having multi-layer optical lenses (30) comprises: an LED wafer (21), at least an inner protective layer (31) covering the wafer (21) and its lead point, an outer protective layer (32) covering the inner protective layer (31), and the hardness of the inner protective layer (31) is higher than that of the outer protective layer (32). Procédé de fabrication d'une DEL (20) comportant des lentilles optiques multicouches (30) comprenant les étapes consistant à : fournir une tranche de DEL (21) (S10); former une couche
