FIELD: lighting.
SUBSTANCE: invention relates to automotive lighting device with led chips. Lighting fixture contains lighting module, formed by light-emitting unit containing light sources-led chips able to emit optical radiation to obtain distributed beam. Inside illumination device has optical part, by means of which part of emitted light radiation can be displaced so that projected image from light-emitting unit can be obtained outside distributed beam. Projected image from light-emitting unit comprises such amount of lit surfaces, which corresponds to number of light sources located in light-emitter.
EFFECT: reliable detection of failure of light sources (separate light-emitting diodes) is achieved.
