Abstract: The invention relates to a lighting device (6) having a light mixing element (1) with a light inlet surface (2) and a light outlet surface (3); multiple light sources (5, 5'), the primary light (P) of which can be emitted onto the light inlet surface (2); a wavelength conversion device (8, 9) with a support (9) on which a luminescent volume (8) is arranged that can be illuminated by means of primary light (P) emitted from the light outlet surface (3); and at least one outcoupling optical unit (10) for shaping a useful light (P, S) emitted from the wavelength conversion device (8, 9), said outcoupling optical unit having at least one non-imaging safety region (11). The multiple light sources (5, 5') emit the primary light (P) at an angle (ß) onto the light inlet surface (2), and the at least one safety region (11) assumes a position on the outcoupling optical unit (10), said position corresponding to a region (M2) with a high intensity of the primary light (P) when the luminescent volume (8) is removed. The lighting device (6) can be used in particular on a vehicle lighting device, in particular a headlight.

Abstract: The lighting device (1, W) comprises at least one primary light source (2), a phosphor volume (4) spaced apart therefrom and serving for at least partly converting the primary light (P) into secondary light (S), at least one light sensor (5, 7) for detecting light (P, S) generated by means of the at least one primary light source (2), and an evaluation device (9) for determining a case of damage to the phosphor volume (4), wherein the lighting device (1, W) comprises at least one additional light source (Z1, Z2, Z3) for irradiating the phosphor volume (4) and is designed to operate the at least one additional light source (Z1, Z2, Z3), the at least one light sensor (5, 7) and the evaluation device (9) with primary light source (2) switched off. A method serves for determining a case of damage to a phosphor volume (4) of a lighting device (1, W), wherein the method comprises at least the following steps: irradiating a phosphor volume (4) only by means of the additional light source (Z1, Z2, Z3) and determining a case of damage to the phosphor volume (4) on the basis of sensor data of at least one light sensor (5, 7).
