 First, what is skin effect

MR16 

Called skin effect skin effect, when an alternating current through the conductor, the current will be focused on the conductor surface flow, this phenomenon is called the skin effect. Skin effect is electromagnetic, vortex study (eddy current) terminology. This phenomenon is energized ferromagnetic material, ferromagnetic material near unpowered, the ferromagnetic material is not energized in the opposite direction of the magnetic field generated on the surface, with the cutting magnetic field lines will generate a current, this current is called the vortex current, this phenomenon is that the skin effect.

Second, the principle of the skin effect

The skin effect is a current or voltage with high frequency of conduction electrons in the conductor, the conductor will be gathered to the total surface, not evenly distributed throughout the cross-sectional area of ​​the conductor. Skin effect increases the effective resistance of the  LED Flexi conductor. The higher the frequency, the skin effect is more significant. When a high frequency current through the wires, the wire can be considered current is only a thin layer on the surface flows, which is equivalent to the wire cross-section decreases,
