mounting the led 12 on a metal core printed circuit board pcb 18 the pcb 18 is directly mounted to the metal host light fixture to transfer the heat to the fixture and then to the ambient environment through radiation and convection methods this technique eliminates the need for any other special heat sinking device referring to fig3 5 the led board 18 includes a first top surface 13 and a second bottom surface 15 and is circular in shape generally the led board is small in diameter and is configured to easily mount within an existing spotlight or reading light type fixture as can be seen in fig1 and 7 the led board 18 is configured to be substantially the same size as the electronics board 16 the led board 18 has four threaded holes 20 which are used to attach the led lamp module 10 to the host fixture there are two other holes 22 in the center of the led board 18 to channel power leads through the base of the host fixture to the electronics board 16 two additional threaded holes 24 are provided to mount the electronics boards 16 the led board 18 has an aluminum backing 21 or coating on the second bottom surface that mates with the host fixture 26 to transfer heat from the led 12 as shown more clearly in fig7 the led 12 is mounted to the first surface 13 of the led board 18 and the secondary optical element 14 is placed e g epoxied over the led 12 an exemplary optical element is an l 2 optics.
