How to decrease the voltage dropping

How to decrease the voltage dropping, You can use the below 3 methods: 
a.  Increase the thickness of Copper Layer to make the current transmit 
    quicker or bigger to improve the voltage dropping.
b. Using the electric way to boost the voltage at each section or boost 
    the current at each section, we are using constant current Triode and 
    constant current IC to improve the voltage dropping or make the 
    beginning and end of strips at the same brightness output.
c. Recommend the higher voltage input version instead of lower voltage 
    input version. 24VDC LED strips will definitely better than the 12VDC 
    strips at 5 meters running.
