Abstract: A thermally conducting reflector is employed to serve as dual-use thermal conductor and light reflector for collimating a multi-chip LED array. The thermally conducting reflector consists of a heat sink, item, a reflector made of a thermally conducting and optically reflective material such as aluminum, item, a transparent cover, item, and lamp base that is electrically isolating, item and a common lighting electrical connector, item, illustrated as an Edison type screw base. The novelty in the present invention is how the items are structured to work together to dissipate heat.

Abstract: A light emitting diode (LED) retrofit downlight light module (DLM) having a housing with an LED downlighting module containing a lighting exit port and connected to a reflector and trim ring having an illumination outlet. The DLM is inserted into an access hole after the existing fixture has been removed. By inserting the DLM into the access hole, a retention device compresses on contact with the entry surface surrounding the hole perimeter. Subsequent to the pivot point of the retention device passing the first surface, the retention device begins to apply a frictional force to the hole perimeter, thereby retaining the DLM within the access hole, without need of tools during installation.
