Red LED
Small emission spot, red LED using current confined chip
L7868 series
L7868/-02 are red LEDs with a microball lens bonded to the current-confined structure chip surface. L7868-01 uses the same structure LED chip
with no microball lens and provides a smaller emission spot of
150 m. L7868-02 uses a glass lens window for even narrower directivity (beam
spread).
