Abstract

Operating parameters of power LEDs are strongly coupled and are mutually dependent. There have been lots of attempts to provide with different kinds of multi-domain LED models with different complexity. This paper gives an overview of recently published models and suggests a practical approach in which the forward current is split into two parts in a straightforward manner. One current component is derived from the LED's measured radiant flux directly, the other component is calculated as the difference of the net forward current and this current component associated with light emission. Parameters of the proposed model can be identified by usual means. The paper proposes an AC measurement technique to validate the full implementation of the model.
