The design technology LED PCB board

We have some advice for layout designer of LED PCB board.
①In design, the ground layer and power layer were separated and echo has a layer.There are has been a decrease in inductance between the ground layer and power layer.

②reduce the segmentation of ground layer and power layer, this will reduce the inductance and Increase the stable for LED PCB circuit.
③Shorten the connect wire length between the drive circuit and LED,this also will Reduce the inductance of conductor.

④ 10 uF Tantalum Capacitor and 0.1uF monolithic ceramic capacitor be located close to LED drive signal source. This will reduce noise and increase led response time.
