  • Patent number: 7931386
    Abstract: A flexible lighting strip includes an insulated flexible electrical power cord and spaced apart modules connected therewith. Each module includes a circuit board with a cavity, indentation, or opening and an encasing overmolding defining a fastener-receiving slot or opening aligned with the cavity, indentation, or opening of the circuit board. Power cord conductors are separated at the connection with each module to define a gap receiving a portion of the circuit board. A separate tiedown is secured to the power cord. Conductive elements receiving electrical power from the power cord and delivering electrical power to the circuit board include an insulation-displacing portion and a recess receiving at least a portion of the power cord and including a retaining barb or hook. An adhesive tape or strip is disposed over at least one overmolding opening to prevent water ingress to the circuit board.

  • Patent number: 7687288
    Abstract: A method of manufacturing a lighting module comprises: mounting one or more light emitting diode (LED) packages on a circuit board to define a lighting unit; and injection overmolding the entire lighting unit except the one or more LED packages using a single type of overmolding material. A lighting module comprises: one or more LED packages mounted on a circuit board; and an injection overmolding sealing the circuit board, the injection overmolding not having openings corresponding to piece holding pins, the injection overmolding not covering at least a light emitting portion of the one or more LED packages.

  • Patent number: 7633055
    Abstract: An optoelectronic device assembly includes a circuit board and an optoelectronic device disposed on the circuit board and electrically connected with the circuit board. An annular gasket is disposed on the circuit board and surrounds the optoelectronic device. A sealant is disposed over and seals at least a portion of the circuit board and also covers at least an outer annular portion of the annular gasket. The sealant is not disposed over the optoelectronic device. In a method, an optoelectronic device is disposed on a circuit board, the disposing including electrically connecting the optoelectronic device with the circuit board. An annular gasket is disposed on the circuit board to surround the optoelectronic device. The circuit board is sealed with a sealant that also covers at least an outer annular portion of the annular gasket, but does not cover the optoelectronic device.
