Light emitting/receiving module
P8212
Integrated light emitting/receiving elements for automobile VICS
P8212 is a light emitting/receiving module consisting of an LED array and a photodiode in the same small package. The width of
this module is minimized so that automobile antennas can be designed thin. A lens is also fitted onto the photodiode to increase
the amount of input light. Although the lens makes the photodiode directivity narrow, this problem was solved by separating the
photodiode optical axis from the LED axis to match the light emitting and receiving areas required for VICS.
