  "textContent": "A lighting device () comprising a light guide () and LED packages () having two or more spatially separated LED chips (,,) is described. The LED packages () generate two or more light outputs at two or more separate wavelengths which are optically coupled into the light guide (). A portion of the two or more light outputs exit the light guide () via a light output surface (). Wavelength dependent modification features () are arranged to modify the intensity of at least one of the two or more light outputs to provide the lighting device () with a homogeneous colour light output. The LED packages () may comprise RGB LED packages, and the wavelength dependent modification features () are arranged to provide a homogeneous white light output. This provides a lighting device () capable of providing low intensity light levels over a large surface area which are thinner and cheaper to produce than those devices known in the art.",
