Zusammenfassung: | An LED light fixture including a mounting surface which supports a circuit board with at least one LED light source spaced thereon, and an optical member which has a back side having a groove facing the mounting surface and surrounding the circuit board. The groove is filled with a resilient in-situ-formed compressible gasket material sealingly engaged with the mounting surface to environmentally seal the circuit board. The mounting surface may be of a heat-sink structure. The in-situ-formed gasket has an inner edge and a plurality of inward projections spaced therealong. Each inward projection extends inwardly to a position facing the circuit board and presses the circuit board against the mounting surface, thereby facilitating heat transfer away from the circuit board. |
