How to use multiple LDR to trigger a led?



Whats the best way to use multiple LDRs to power up an LED? Currently I’m using one LDR which turns on an LED when it senses light. But now I want to use three LDRs (at different locations) to trigger the same LED. The LED should turn on when any of the three LDRs sense light. Thanks in advance!enter image description here
