Abstract

A lighting module for emitting mixed light comprises at least one first semiconductor element which emits unconverted red light, at least one second semiconductor element which emits converted greenish white light having a first conversion percentage, at least one third semiconductor element which emits greenish white light having a second conversion percentage that is smaller than the first conversion percentage, and at least one resistor element having a temperature-dependent electric resistance, the second semiconductor element being connected in parallel to the third semiconductor element.
