Lighting device with thermal coupling element made of thermally conductive plastic

摘要

The lamp (1) has multiple light emitting diodes (LEDs) (16) arranged on a board in a hermetically sealed plastic housing, and a coupling element (10) is made of a thermally conductive plastic that is compatible with the plastic of the housing. The thermal coupling element is installed in an area adjacent to a heat sink to dissipate the heat generated by the LEDs. A heat sink (12) is formed in communication with the outside air. The heat-conductive plastic material is provided as a thermoplastic material, which is comprised of thermally conductive filler.
