Claim 8:
9. A linear lighting device according to claim 1, wherein the interior surface comprises:
a first interior surface and a second interior surface;
the first interior surface being configured such that the second light, reflected by the first interior surface of the cavity and subsequently having impinged upon the surface of the optical module and transmitted through the optical module, is light for which at least 3% of the total luminous flux is in the wavelength range between 400-470 nm, and
the second interior surface being configured such that the second light, reflected by the second interior surface of the cavity and subsequently having impinged upon the surface of the optical module and transmitted through the optical module, is light for which a percentage of the total luminous flux in the wavelength range 400-470 nm is higher than the percentage of the total luminous flux in the wavelength range 400-470 nm of the second light reflected by the first interior surface, by the second interior surface of the cavity having at least one of a reflectivity for light in the wavelength range 400-470 nm which is higher than a reflectivity for light in the wavelength range 400-470 nm of the first interior surface, and a reflectivity for light in the wavelength range 470-650 nm which is lower than a reflectivity for light in the wavelength range 470-650 nm of the first interior surface.
