TECHNOLOGY<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
This sale is for your choice of 20mm, 16mm or 10mm COPPER PCBs. These are bare stars no LEDs are included.
Available emitter foot prints:
Cree XML, XML2
Cree XPG, XPG2, XPG3, Nichia 219
Cree XHP50
Cree XHP70
These
copper core PCBs significantly boost the performance of LEDs. The
direct thermal path technology makes it possible to drive the emitter
much harder than factory specification.
The
emitter is soldered DIRECTLY to the copper heat pad. . These are high
quality, and preform well above standard aluminum MCPCBs. Boards that
simply use copper for the base and retain use of the crystal substrate
layer in the center will not give you the same performance.
Using
these stars in combination with PROPER heat sinking emitters can be
driven to significantly higher than rated capacity. Output Gains are
seen even at DOUBLE the rated drive current of emitters. Output
increases are also achieved at some standard currents. Output graphs
compare standard MCPCB with copper MCPCB in controlled test (graphs
thanks to BLF member Match).
