    • A bendable light emitting diode (LED) array in accordance with the present invention includes heat spreaders, dielectric material disposed above each heat spreader, and a bendable electrical interconnection layer disposed above these heat spreaders and electrically insulated from these heat spreaders by the dielectric material. At least one via passes through the dielectric material above each heat spreader, and at least one LED die is disposed above each via. The bendable electrical interconnection layer may be a lead frame comprising metal pathways that electrically interconnect some or all LED dice in series, in parallel, in anti-parallel, or in some combination of these configurations. Each via contains a thermally conductive material in thermal contact with the corresponding heat spreader below it and in thermal contact with the corresponding LED die above it. The LED dice may be thermally and electrically coupled to submounts disposed above corresponding heat spreaders in some embodiments.
    • 根据本发明的可弯曲发光二极管(LED)阵列包括散热器,设置在每个散热器上方的电介质材料,以及设置在这些散热器上方的可弯曲电互连层,并且通过电介质材料与这些散热器电绝缘。 至少一个通孔穿过每个散热器上方的电介质材料,并且至少一个LED管芯设置在每个通孔上方。 可弯曲的电互连层可以是包括金属通路的引线框架,该金属通路将一些或所有LED骰子串联,并联,反并联或以这些配置的某种组合串联连接。 每个通孔都包含与其下方相应的散热器热接触的导热材料,并与其上方的相应的LED管芯热接触。 在一些实施例中,LED骰子可以热和电耦合到设置在相应的散热器上方的底座。

    • Method and apparatus are provided for thermally coupling one or more electronic devices to a heatsink. The apparatus comprises a heatsink having a substantially planar upper surface, a wiring board (PWB) with a through-hole for receiving the device such that a principal face thereof is in thermal contact with the heatsink, its electrical leads are captured between at least a portion of the wiring board and the heatsink, and a top of the device protrudes through the PWB. The method comprises placing the device in the through-hole with its base exposed on and protruding from the underside of the PWB, attaching its electrical leads to contacts on the wiring board and pressing the PWB toward the heatsink with the leads captured there between. An electrically insulating thermally conducting layer is desirably placed between the wiring board and the heatsink.
    • 提供了用于将一个或多个电子装置热耦合到散热器的方法和装置。 该装置包括具有基本平面的上表面的散热器,具有用于接收该装置的通孔的布线板(PWB),使得其主面与散热器热接触,其电引线至少被捕获在 部分布线板和散热器,并且设备的顶部突出穿过PWB。 该方法包括将设备放置在通孔中,其基座暴露在PWB的下侧并从PWB的下侧突出,将其电引线连接到接线板上的触点上,并将PWB朝向散热器与其间捕获的引线相压。 电绝缘导热层优选放置在布线板和散热片之间。
