As I understand, you want your screen to turn off when the lid is closed and back again after opening the lid?

Under root privilege:

#sysctl hw.acpi.reset_video=1

Now close the lid and open it again, the light should be back.

For permanent setting:

# echo "hw.acpi.reset_video=1" >> /etc/sysctl.conf
