ELECTRICALLY ISOLATED AND THERMALLY RADIATED LED MODULE

摘要

An electrically isolated light-emitting display (LED) module efficiently transfers heat away from electronic components by thermally conducting the heat to the outside walls of an enclosure. An embodiment includes a plastic enclosure having thin plastic walls that define an opening, a plastic cover having a lens and configured to cover the opening, a power supply unit (PSU), a light-emitting diode (LED) operably connected to the PSU, and a thermally conducting potting material. The potting material is deposited into an interior volume of the plastic enclosure to cover the PSU, contact a back portion of the LED, and to thermally connect the PSU and the LED to the thin plastic walls of the plastic enclosure without covering a front portion of the LED.

1. An LED module assembly comprising:
a plastic enclosure having thin plastic walls providing an interior volume, and wherein a top portion of the walls defines an opening; a plastic cover comprising a lens and configured to cover the opening; a power supply unit (PSU) comprising electronic components connected to a PSU substrate, the PSU situated within the interior volume of the plastic enclosure; a light-emitting diode (LED) operably connected to the PSU and situated within the interior volume of the plastic enclosure such that the LED is aligned with the lens of the plastic cover; and a thermally conducting potting material deposited into the interior volume of the plastic enclosure such that it covers the PSU electronic components, contacts a back portion of the LED, and thermally connects the PSU, the PSU substrate and the LED to the thin plastic walls of the plastic enclosure without covering a front portion of the LED.
