Abstract
In an embodiment a light emitting device includes a light source, a switching element having an input capacitance associated therewith, the switching element being configured to control a current flow to the light source in accordance with a charging of the input capacitance, a voltage control element coupled with the switching element and having a voltage supply node, the voltage control element having a second capacitance associated therewith, wherein the voltage control element and an input of the switching element are coupled to one another such that the voltage control element and the input of the switching element form a capacitive voltage divider and a driving element configured to provide a driving voltage at the voltage supply node, the driving voltage being greater than a maximum allowable input voltage of the switching element, wherein a relationship between the input capacitance and the second capacitance is in accordance with a relationship between the driving voltage and the maximum allowable input voltage.
