Shenzhen Hoion Lighting Co.,Ltd | Updated: May 07, 2015

Ripple of influence LED lifetime depends on the size and number of each line. Branch number LED the same cases, larger ripple LED lifespan shorter; ripple the same cases, branch number LED more ripple effect on LED the smaller, longer life.

For example: power supply output voltage of 12V, sharp Crest-500Mv peak, each branch LED number is 4

1, without a ripple under the condition of each LED to withstand voltage of 12 ÷ 4 tablets =3V

Each LED after 2 and superimposed ripple withstand voltage (12V ÷ 0.5V) ÷ 4 tablets =3.12V
