#89998 - Finding light source position?



Excuse me for unstructured sentences!
I search the posts to find my answer
but i don't find it.
I need to find light source position such as sun
at any time.
One of my idea is half sphere with many LDR(Light Depended Resistor)
in a fix position and special cover,
so only straight rays can pass through cover
another is
A robot with 2 step motor
when the first is rotating 360 degrees,the second increasing one degree
and the first rotating 360 degrees again until
the second reaches to 90 degrees.

I know second way is more difficult than one.
Do you think to this subject before
or
Would you have any good idea?
Thanks for your times

Mehdi
