LED Injection Modules was used to display AD letters and night signages,not only take advantage in night time,but also in daytime.When night falls,LED lighting module brings it’s gorgeous lights,that makes visible for customers from distance ( out door LED module operating requirements,click << Key knowledge point of LED module
>>).
So how to use led sign module properly ?that’s also the way to ensure security and operating time .Currently used channel letter light source,usually input the voltage by regular settings ,normal types are DC12V 3LED,5LED,6LED,,needs putting out by constant voltage power driver.So pay attention to open and close the driver when installation,remember not connect 220V AC,or LED will be burnt.
Second is to use it properly ,don’t work overload ,load power ratio of switching power supply shoud be 1:0.8.If exceed 25 series ,it should be separated and connect,then parallel them with copper wire which is bigger than 1.5 SQMM.
Third,visibility between modules should be around 5m,to ensure the enough brightness.
Fourth,pay attention to voltage decreasing problem,try paralleling some return circuit,distribute voltage and current properly,avoid inconformity of brightness and burn the PCB because of too big single current.
