    • The invention describes a lighting circuit (1) comprising a primary set (11, 13) of light-emitting diodes (110, 130) of a first color and a secondary set (12) of light-emitting diodes (120) of a further color; wherein a temperature-dependent reduction in light output of the primary set (11, 13) of light-emitting diodes (110, 130) is greater than a temperature-dependent reduction in light output of the secondary set (12) of light-emitting diodes (120); and a flux ratio fixing arrangement realized to maintain an essentially constant ratio between the light output of the primary set (11, 13) and the light output of the secondary set (12) during a temperature-dependent overall reduction in light output of the light-emitting diodes (110, 120, 130) of the lighting circuit (1). The invention also describes a lighting arrangement (4, 4′) for illuminating objects (40, 41) with light of a predefined color point, which lighting arrangement (4, 4′) comprises at least one such lighting circuit (1), wherein the light-emitting diode sets (11, 12, 13) of a lighting circuit (1) are chosen to emit, in combination, light of the predefined color point at an initial temperature, and wherein the flux ratio fixing arrangement of the lighting circuit (1) is realized to maintain that color point at a temperature higher that the initial temperature.
