Product Binning and Labeling
Purpose of Product Binning
In the manufacturing of semiconductor products, there is a variation of performance around the average values given in the technical data sheets.
For this reason, Philips Lumileds bins the LED components for luminous flux, color and forward voltage (V_f).
Decoding Product Bin Labeling
LUXEON C emitters are labeled using a four digit alphanumeric code (CAT code) depicting the bin values for emitters packaged on a single reel.
At this time LUXEON C is binned for color and luminous flux. All emitters packaged within a reel are of the same 2-variable bin combination. Using
these codes, it is possible to determine the optimum mixing and matching of products for consistency in a given application. Reels are labeled with
a four digit alphanumeric CAT code following the format below.
ABCD
A, B and C = Color bin (84A, 85A, etc.)
D=
Flux bin (7 or 8)
Although several bins are outlined, product availability in a particular bin varies by production run and by product performance.
