Abstract

An LED lighting device (5) comprises first and second LEDs (6 8) arranged to respectively emit first and second beams (7 9) of white light having first and second different respective colour temperatures and a beam splitter (10) arranged to split the first and second light beams (7 9) respectively into a first reflected portion of the first and second beams (11 3) and a second transmitted portion of the first and second beams (12 14). The LED s (6 8) and the beam splitter (10) are arranged spatially such that the transmitted portion of the first beam (12) and the reflected portion of the second beam (13) overlap into a first resulting beam (15) of intermediate colour temperature between the first and second colour temperatures and the reflected portion of the first beam (11) and the transmitted portion of the second beam (14) overlap into a second resulting beam (16) of the same intermediate colour temperature.
