Light type adjusting screw rod is installed in the second lens lamp group, and screw head is abutted with the second radiator by step 2, the body of rod
It is threaded through in the adjusting through-hole, threaded portion is threadedly coupled with screw hole is adjusted；
Step 3, be powered the first light source mould group and second light source mould group lighted in double lens lamp group, so that first light source mould group
The light issued with second light source mould group is projected respectively to light type detection screen；
Step 4 detects the real-time light information on camera acquisition light type detection screen by light type, and real-time light is believed
Breath is transferred to master control computer；
Step 5, master control computer match the real-time light information received with preset lighting programmers, if matching at
Function is then exported and is successfully instructed, and is then removed light type adjusting screw rod and is tightened each fixed screw, and Dimming operation is completed；If
With failure, master control computer calculates error, then starts light type adjusting motor and to twist screw rod forward or reverse, twists screw rod and drive
Light type adjusting screw rod forward or reverse, and then drive the second lens lamp group be moved to designated position so that the first lens lamp group and
The dead line of second lens lamp group keeps certain registration, then removes light type adjusting screw rod and twists each fixed screw
Tightly, Dimming operation is completed；
Step 6 extinguishes the first light source mould group and second light source mould group in double lens lamp group and removes double lens lamp group.
