Normally, LED special power (DC 12V) have several 12V output terminals, we should be balanced each terminal load whenusing it, lest big loaded terminal fever severe then caused premature oxidation and damage. Note the lead in point of power supply should better choose the whole LED central position. Ensure the whole LED brightness even, and prevent local LED fever bad then accelerated attenuation, the power supply and LED source should be polish and deburring to protect the power cable.
Switching power supply and LED light source attachment distance should be satisfied the following requirements:
The greatest distance of 318 number line diameter should be 8 meters, WQP line diameter, according to the actual engineering situation to determine switch power types.
Example:
1, an engineering need use white three LEDs shining module X = 500, check the value of white three LEDs shining module power is WMP = 0.24W.
2, calculation shining module general power loss value in engineering WQP = WMP * X = 0.24 * 500 = 120W.
3, matching the power supply should consider 80% of effective power consumption, namely the switch power of power project need to use is equal to or greater than the total power of 150 W.
According to the actual situation you can choose one 150W or three 50W power supply.
