It is the dark sensor, you can say. it detects the difference of illumination in the shadow & in the normal light and turn its circuit ON & OFF.
it is made by joining many small circuits. each small circuit contains:
1) two LEDs
2) two npn c1383 transistors
3) one resistance of 1K
4) one resistance of 10K
5) one variable resistor 0-20K (to adjust the sensitivity)
6) one LDR
you can see more pics on my "Facebook" account.
