We verified the component dimensions to ensure a correct fit. 2. we attached the CXA2530 LeD to the heat sink with a small amount of thermally conductive compound.12 Thermally conductive epoxy can also be used.13 3. we fed the driver output wires through the heat sink and, following the recommendations in Cree’s Soldering and Handling Application Note for the CXA family of LeDs14, soldered them onto the CXA2530 LeD. 4. We tested the connection by applying power to the LED and verified that the LeD lit up. 5. we placed a plastic alignment ring15 over the LeD and positioned the ring so the LeD was centered on the heat sink. 6. we secured the plastic alignment ring to the heat sink with screws. 7. we secured each end of the driver to the heat sink with a bracket and screw. 8. we fed the driver input wires through the center hole in the screw-in base. 9. we screwed the base to the heat sink, enclosing the driver. 10. We placed the reflector in the heat sink so the opening aligned with the LeD. 11. We placed the cover glass on the reflector and screwed the front optic cover ring to the heat sink to secure the cover glass and the reflector to the heat sink. 12. we attached the track adaptor bracket to the lamp assembly with decorative screws. 13. we connected the driver input wires to the track adaptor. 14. We performed final testing. 12 Dow Corning Thermally Conductive Compound, TC-5026, www.dowcorning.com/content/publishedlit/11-1689a-01.pdf 13 refer to Cree’s Chemical Compatibility application note for compounds that are safe to use with Cree LeDs.
