lamp is only partially relevant.
Table 7 shows the design goals for this project.

We used Cree’s Product Characterization Tool (PCT) tool to determine the drive current for the design. Figure 1 shows basic electrical data
and optical output from the PCT. We estimated 90% optical efciency, 88% driver efciency and a solder-point temperature (T
SP
) of 70°C.
Figure 1:
The PCT output shows that, at 400mA, a single XLamp CXA1512 LED produces the desired lumen output and efcacy.
Proper thermal management is a key component of any successful LED-based lamp or luminaire design. Operating at 17W of power in
this retail track light design, the XLamp CXA1512 LED requires a heat sink to dissipate this thermal load. The heat sink in this design must
