Talking of heating problem, we may think about excellence of the flexible led strip, but actually this is simply not the truth. Although led light is cold light illuminator, it’s speaking about from the theory of led illuminating, this doesn’t signify led wouldn’t create heat. Heating theory of LED is complicated to clarify. Here let’s target the main two heating problems in the led strips industry, most factories facing it.
Exclusion the heating problem of LED itself, the best way to solve any additional heating caused by processing technology and improper circuit design? To find the answers, let’s firstly know the main two reasons causing LED strips heating.
This most common used voltage of led strips are LED Strip 12V and led strip 24v. LED strip 12V is three strings of multiple parallel connection structure and led strip 24V is six strings. Because Led strips need to connect to be used, while how much time for each and every led strip, it’s related to circuit width and copper foil thickness. Because a measure of current strength is related to the circuit cross-sectional area, thus if ignoring this factor in wiring, when the connection length exceeds the current, super bright led strip lights is going to be heated because of overcurrent, and thus broke the wiring board and at the same time lessen the led lifespan.
Because Led strips are series parallel circuit, when short circuit occur in one set of loop, it would cause other led strips with the same line voltage rise, and led lights become brighter, thus create more extra heat. The most apparent situation occur in 5050 led strip. Regarding led strip 5050, anyone chip has short circuit dexnpky31 the loop can cause other led light current rise twice higher, from 20mA to 40 mA, thus heat will probably be increased fast and burn on the wiring board. This issue is tough to be found because short circuit would not affect the 12 volt led lights normal illumination. When inspection, if just take note of if the illumination however, not the brightness, or overlook the outer inspection, by simply electrometric measurement, this issue could be ignored.
