The voltage versus current characteristics of an LED is similar to any diode. Current is approximately an exponential function of voltage according to the Shockley diode equation, and a small voltage change may result in a large change in current. If the voltage is below or equal to the threshold no current flows and the result is an unlit LED. If the voltage is too high, the current will exceed the maximum rating, overheating and potentially destroying the LED. NettetAbstract: An LED driver is the brain of an LED lighting system. It provides power conversion, load regulation, and downstream component protection. LED drivers are …

Nettet5. feb. 2024 · An LED light that is rated for constant voltage usually specifies the amount of input voltage it needs to operate correctly.
