  • Solid state light emitter die having a heat spreader between a plurality lead frame
    Patent number: 10910540
    Abstract: A solid state light emitter package (200), a lamp, a luminaire and a method of manufacturing the solid state light emitter package are provided. The solid state light emitter package comprising a solid state light emitter die (230), a first and second lead frame (210, 220), an electrical insulating material (242, 244), a thermal element (250) and a bridging element (260). The first and second lead frame are electrically isolated from each other and provide power to said die. Said die is at least partially provided on the first lead frame. The thermal element is in between the first and second lead frame and is electrically isolated by the electrical insulating material from said lead frames. The thermal element is at least one of a heat absorber or a heat spreader. The bridging element bridges the electrical insulating material and the thermal element and provides an electrical connection between said die and the second lead frame.
