LED strip lights are typically available in 12V and 24V specifications. The 12V category adopts a 3-series multiple parallel design while the 24V variant employs a 6-series multiple parallel system. The maximum length of the strip that can be connected is dictated by the circuit’s width and the copper foil thickness in the design as LED strips are meant for connected usage.
The current capacity per unit area is linked to the circuit’s cross-sectional area. Overlooking this aspect during wiring may cause the strip to overheat when the connected length surpasses the circuit’s current capacity. This not only damages the circuit board but also cuts short the LEDs’ life expectancy.
Given that LED strips are designed in series and parallel configurations, a short circuit in one circuit group will raise the voltage of the other LEDs in the same group, leading to heightened brightness and heat production.
Taking 5050 light strips as a case in point, a short circuit in any single chip circuit will cause the current of the short-circuited LED to double, from 20mA to 40mA. While the LED’s brightness will soar, so will the heat produced. In extreme instances, the circuit board may burn out within minutes.
Yet, this problem is often overlooked as it’s relatively disguised. If the testing personnel concentrate solely on whether the LED is illuminating and neglect to check for abnormal brightness or skip visual inspection in favor of electrical tests, such issues are frequently missed. This is a common reason why many LED strip light producers face customer complaints about overheating but struggle to identify the root cause.
