Improved overload protection for a light emitting diode driver

According to an example embodiment, a driver apparatus for driving one or more light emitting diodes is provided. The driver apparatus comprises a power converter portion for converting operating power supplied to the driver apparatus into a driving current for light emitting diodes, the power converter portion comprising one or more power converter stages, a control portion for issuing control signals to control the power converter portion, a current monitoring portion for providing a current measurement signal indicative of a current in a certain power converter stage of the power converter portion, and a temperature monitoring portion for providing a temperature measurement signal indicative of ambient temperature of the driver apparatus, wherein the control portion is configured to issue, in response to the current measurement signal indicating a current exceeding a threshold value, one or more control signals for limiting the output power of said certain power converter stage and to set the threshold value based on the temperature measurement signal. Moreover, a computer program for controlling operation of the driver apparatus is provided.
