Talking of heating problem, we might think of the quality of the led strip lights, in fact this is simply not the truth. Although led light is cold light illuminator, it’s referring to through 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 inside the led strips industry, most factories facing it.
Exclusion the heating problem of LED itself, how you can solve any additional heating due to processing technology and improper circuit design? To obtain 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 must connect for usage, while how long for each and every led strip, it’s associated with circuit width and copper foil thickness. Because a way of measuring current strength is involving the circuit cross-sectional area, thus if ignoring this factor in wiring, as soon as the connection length exceeds the current, led industrial lighting will be heated as a consequence of overcurrent, and therefore broke the wiring board and at the same time minimize the led lifespan.
Because Led strips are series parallel circuit, when short circuit occur in one list of loop, it is going to cause other led strips in the same line voltage rise, and led lights become brighter, thus create more extra heat. The most obvious situation happens in 5050 led strip. As for led strip 5050, anyone chip has short circuit dexnpky31 the loop will result in other led light current rise twice higher, from 20mA to 40 mA, thus heat will be increased fast and burn on the wiring board. This challenge is difficult that can be found because short circuit would not change the 12 volt led lights normal illumination. When inspection, if just focus on if the illumination yet not the brightness, or forget about the outer inspection, by simply electrometric measurement, this problem can be ignored.
