Said base features such configuration and characteristics as to provide, together with two retaining rings and a deformable core hitch, for a high degree of protection against penetration of solid bodies and liquids and for a high thermal dissipation towards the external environment. ## Claims ### Claim at position 1 1-16. (canceled) ### Claim 17 A LED lamp for large environments, comprising a LED-holder base, on the lower surface of which there is present at least one seat for at least one LED light source, said base being integrally connected, on the upper side, to a heat sink and, on the lower side, to a focusing lens, characterized in that it comprises an upper retaining ring and a lower retaining ring, accommodated in an upper seat and a lower seat, respectively, which upper seat and lower seat are cut on the upper surface and on the lower surface respectively of said base, so as to be interposed between said base and said heat sink and said focusing lens respectively. ### Claim 18 (depends on 17) The LED Lamp according to claim 17, characterized in that the upper surface of said base includes a core hitch seat that accommodates an at least partially deformable core hitch, internally to which electrical cables pass through to supply power to said LED light source. ### Claim 19 (depends on 18) The LED Lamp according to claim 18, characterized in that said lower seat for the lower retaining ring circumscribes and perimetrically delimits the area occupied by said at least one LED light source. ### Claim 20 (depends on 19) The LED Lamp according to claim 19, characterized in that said upper seat for the upper retaining ring circumscribes and perimetrically delimits the seat of the core hitch. ### Claim 21 (depends on 20) The LED Lamp according to claim 20, characterized in that it comprises a power supply unit for supplying power to at least one LED light source located above said heat sink and integrally connected thereto; said power supply unit being in turn connected to anchoring means of the LED lamp. ### Claim 22 (depends on 21) The LED Lamp according to claim 21, characterized in that between said power supply unit and said heat sink there are interposed one or several metal spacers. ### Claim 23 (depends on 22) The LED Lamp according to claim 22, characterized in that a plurality of projecting fins extend from the upper surface of said heat sink. ### Claim 24 (depends on 23) The LED Lamp according to claim 23, characterized in that said base is made from aluminum-based metal alloy. ### Claim 25 (depends on 21) The LED Lamp according to claim 21, characterized in that said base is made from aluminum-based metal alloy. ### Claim 26 (depends on 17) The LED Lamp according to claim 17, characterized in that said lower seat for the lower retaining ring circumscribes and perimetrically delimits the area occupied by said at least one LED light source. ### Claim 27 (depends on 26) The LED lamp according to claim 26, characterized in that said upper and lower retaining rings are made from silicone. ### Claim 28 (depends on 17) The LED lamp according to claim 17, characterized in that it comprises at least one slot adjacent to the side edge of one of said at least one seat for at least one LED light source. ### Claim 29 (depends on 17) The LED lamp according to claim 17, characterized in that said LED light source is a COB (Chip-On-Board) LED. ### Claim 30 (depends on 17) The LED lamp according to claim 17, characterized in that said base is disc-shaped. ### Claim 31 (depends on 17) The LED lamp according to claim 17, characterized in that said base features a thickness of approximately 15 millimeters. ### Claim 32 (depends on 18) The LED lamp according to claim 18, characterized in that the power for said LED light source is supplied by at least one cable which crosses said base in a feed through which is coated by an insulating material. ### Claim 33 (depends on 32) The LED lamp according to claim 32, characterized in that said insulating material is a polyimmide film. ### Claim 34 (depends on 18) The LED lamp according to claim 18, characterized in that said upper seat for the upper retaining ring circumscribes and perimetrically delimits the seat of the core hitch. ### Claim 35 (depends on 34) The LED lamp according to claim 34, characterized in that said core hitch is made from EPDM (Ethylene-Propylene Diene Monomer).
