  "description_excerpt": "The present invention relates generally to luminaires. More specifically, the invention relates to a light emitting diode (LED) module that is used in a recessed luminaire.\n\nLEDs offer benefits over incandescent and fluorescent lights as sources of illumination. Such benefits include high energy efficiency and longevity. To produce a given output of light, LEDs consume less electricity than incandescent or fluorescent lights. Additionally, on average, LEDs last longer than incandescent or fluorescent lights before failing.\n\nThe level of light a typical LED outputs depends upon the amount of electrical current supplied to the LED and upon the operating temperature of the LED. That is, the intensity of light emitted by the LED changes according to electrical current and LED temperature. Operating temperature also impacts the usable lifetime of LEDs.\n\nAs a byproduct of converting electricity into light, LEDs generate heat and raise the operating temperature, resulting in efficiency degradation and premature failure. Typically, a heat management system, such as a heat sink, is used in conjunction with the LEDs to facilitate maintenance of proper LED operating temperatures. Conventional LED-based recessed luminaires include a housing and a conventional LED module that is coupled within the housing. The conventional LED module includes a heat sink, a fastening device for facilitating coupling between the conventional LED module and the housing, and one or more LEDs. The housing includes a cavity formed therein and an opening at one end.",
