Reported to contain a SemiLEDs die on flexible copper substrate and the subject of much controversy and feuding between Nichia and Seoul Semiconductor, this device has indeed a very interesting die.
MuAnalysis has used a large variety of analytical techniques including electron microscopy with photochemical delineation and EDX to probe the technology of this LED lamp and reveal its secrets. Protection circuitry, process sequence and epi-stack are described in detail supported by plenty of photos, tables and graphs.
