摘要：

In this paper, a new method of measuring transient thermal impedance of power LEDs and radial power is proposed. The idea of the method is described, and the measurement setup realizing this method is presented. The measurement error of the proposed method is analyzed, and some results of measurements realized with the use of the proposed method are presented and discussed. Selected results of measurements are compared with the measurements results realized with other methods described in the literature.
