In the use of LED panel lights, we often encounter that LED panel lights are not bright, the packaging companies, enterprise applications, and units and individuals, are likely to encounter, this is the people in the industry say that the phenomenon of dead lights .
The dead lights of LED panel lights are the key to affect product quality, reliability, how to reduce and eliminate dead lights, improve product quality and reliability, are the key issue for packaged enterprise that need to be resolved. Here is some analysis and reason below:
First , LED panel lights caused excessive leakage current PN junction failure, the LED lights point is not lit, which generally does not affect other LED lights working;
Second, the internal LED panel lights connecting leads disconnected, causing death arising from non-current through the LED lights, this situation will affect the normal operation of other LED lights, the reason is due to low voltage LED lights ( red, yellow, orange LED work voltage 1.8V-2.2V, blue, green and white LED operating voltage 2.8-3.2V), are generally required to join with series and parallel, in order to adapt to different operating voltage, the greater series of LED lights more influence, as long as one LED lights inside the connection open, the series circuit will cause a whole string of LED lamp that is not lit, it is visible to see that this case is serious than the first case.
