Automotive LED headlights are more sensitive to temperature changes, if the junction temperature (LED PN junction temperature, PN junction is the LED light source) is higher, then the LED luminous performance will be reduced. Therefore, LED headlights have high requirements for heat dissipation, and good heat dissipation design is needed to ensure the temperature stability of LED components. Since the LED headlights have relatively high heat dissipation requirements, this puts higher requirements on the power inductance in the power module.

The application of power inductance in LED headlights requires low DC impedance, small package and large saturation current, among which low DC impedance of power inductance can reduce DC loss and improve energy conversion efficiency; Small package can increase the internal heat dissipation space of LED; The high saturation current can ensure the reliability of the power inductor.
