摘要： The invention provides a lighting device (100) comprising: —a first solid state light source (10), configured to provide UV radiation (11) having a wavelength selected from the range of 380-420 nm; —a second solid state light source (20), configured to provide blue light (21) having a wavelength selected from the range of 440-470 nm; —a wavelength converter element (200), wherein the wavelength converter element (200) comprises: —a first luminescent material (210), configured to provide upon excitation with the blue light (21) of the second solid state light source (20) first luminescent material light (211) having a wavelength selected from the green and yellow wavelength range, and wherein the first luminescent material excitability for UV radiation (11) is lower than for blue light (21); and —a second luminescent material (220), configured to provide upon excitation with the blue light (21) of the second solid state light source (20) second luminescent material light (221) having a wavelength selected from the orange and red wavelength range, and wherein the second luminescent material excitability for UV radiation (11) is lower than for blue light (21).
