The security light may comprise at least one lamp head with a light source, an inner lens, a filter frame element, an outer lens, an exchangeable mechanical color filter, a locking mechanism, and a sealing mechanism. ## Claims ### Claim 1 A security light, comprising: at least one lamp head having a peripheral edge, the peripheral edge of the at least one lamp head surrounding a light source; an inner lens mountable over and retained on the peripheral edge of the at least one lamp head; a filter frame element positioned between the inner lens and an outer lens and having a filter frame element opening along one side; wherein the outer lens retains the filter frame element in position against the inner lens and mounts to the at least one lamp head positioning the filter frame element between the outer lens and the inner lens; the outer lens having an outer lens opening in substantial alignment with the filter frame element opening; a mechanical color filter slidable through the filter frame element opening and surrounded by the filter frame element; a locking mechanism between the outer lens and the at least one lamp head to structurally retain the outer lens, the filter frame element, and the inner lens on the at least one lamp head; and a sealing mechanism at the filter frame element opening. ### Claim 2 (depends on 1) The security light of claim 1 wherein the inner lens has an inner lens projection. ### Claim 3 (depends on 2) The security light of claim 2, wherein the peripheral edge of the at least one lamp head includes a first channel formed by a first vertical lip element and a second vertical lip element for receiving the inner lens projection. ### Claim 4 (depends on 3) The security light of claim 3, wherein a height of the first vertical lip element is larger than that of the second vertical lip element. ### Claim 5 (depends on 1) The security light of claim 1, wherein a thickness of the mechanical color filter is larger than that of the filter frame element opening along the one side of the filter frame element. ### Claim 6 (depends on 1) The security light of claim 1, wherein the sealing mechanism includes one or more pliable gasket elements at the filter frame element opening along the one side of the filter frame element. ### Claim 7 (depends on 1) The security light of claim 1, wherein the locking mechanism includes a slot and a protrusion, the slot is formed on one of the peripheral edge of the at least one lamp head and a periphery of the outer lens, and the protrusion is formed on the other one of the peripheral edge of the at least one lamp head and the periphery of the outer lens. ### Claim 8 (depends on 7) The security light of claim 7, wherein the slot and the protrusion include a plurality of slots and a plurality of protrusions. ### Claim 9 (depends on 8) The security light of claim 8, wherein the plurality of protrusions include a plurality of elastic body locks and the plurality of slots include a plurality of lock receiving openings. ### Claim 10 (depends on 1) The security light of claim 1, wherein the outer lens further comprises a continuous circumferential flange and/or internal channel substantially surrounding the filter frame element to retain the filter frame element within the outer lens. ### Claim 11 (depends on 10) The security light of claim 10, wherein the continuous circumferential flange of the outer lens and a first vertical lip element of the peripheral edge of the at least one lamp head form a second channel for receiving a filter frame projection. ### Claim 12 (depends on 11) The security light of claim 11, wherein the continuous circumferential flange further comprises a second opening in alignment with a location of the filter frame element opening along the one side of the filter frame element. ### Claim 13 (depends on 12) The security light of claim 12, wherein the mechanical color filter further comprises an extension portion that extends a distance from the second opening on the continuous circumferential flange of the outer lens. ### Claim 14 (depends on 1) The security light of claim 1, wherein the light source includes a plurality of LEDs. ### Claim 15 (depends on 1) The security light of claim 1, wherein the mechanical color filter serves as a light diffuser. ### Claim 16 A security light, comprising: at least one lamp head having a peripheral edge, the peripheral edge of the at least one lamp head surrounding a light source; an inner lens mountable over and retained on the peripheral edge of the at least one lamp head; an outer lens having an opening along one side; a mechanical color filter slidable through the opening along the one side of the outer lens and positioned between the inner lens and the outer lens and surrounded by a gasket ring; and a locking mechanism between the outer lens and the at least one lamp head to structurally retain the outer lens, the mechanical color filter, and the inner lens on the at least one lamp head, wherein the outer lens retains the gasket ring in position against the inner lens and mounts to the at least one lamp head positioning the gasket ring between the outer lens and the inner lens. ### Claim 17 (depends on 16) The security light of claim 16, further comprising an opening filling gasket coupled with the opening along the one side of the outer lens. ### Claim 18 (depends on 16) The security light of claim 16, the mechanical color filter further comprising a gasket strip at a side approximate the opening along the one side of the outer lens. ### Claim 19 A security light, comprising: at least one lamp head having a peripheral edge, the peripheral edge of the at least one lamp head surrounding a light source; an inner lens mountable over and retained on the peripheral edge of the at least one lamp head; a pliable filter frame element positioned between the inner lens and an outer lens and having a filter frame element opening along one side; wherein the outer lens retains the pliable filter frame element in position against the inner lens and mounts to the at least one lamp head positioning the pliable filter frame element between the outer lens and the inner lens, the outer lens has a continuous circumferential flange substantially surrounding the pliable filter frame element to retain the pliable filter frame element within the outer lens and a second opening in alignment with a location of the filter frame element opening along the one side of the pliable filter frame element; a mechanical color filter slidable through the filter frame element opening along the one side of the pliable filter frame element and the aligned second opening on the continuous circumferential flange of the outer lens, and positioned between the inner lens and the outer lens and surrounded by the pliable filter frame element, the mechanical color filter having an extension portion that extends a distance from the second opening on the continuous circumferential flange of the outer lens; and a locking mechanism between the outer lens and the at least one lamp head to structurally retain the outer lens, the pliable filter frame element, and the inner lens on the at least one lamp head. ### Claim 20 (depends on 19) The security light of claim 19, wherein the peripheral edge of the at least one lamp head includes a first channel formed by a first vertical lip element and a second vertical lip element for receiving an inner lens projection, and a second channel formed by the continuous circumferential flange of the outer lens and the first vertical lip element of the peripheral edge of the at least one lamp head for receiving a filter frame projection.
