FIELD: physics.
SUBSTANCE: invention relates to a light sensor device comprising a substrate (18), a first light sensitive area (14, 15), and a second light sensitive area (12, 13), a first optical filter device (22) assigned to said first area (14) and adapted to filter the visible light spectrum and a second optical filter device (24) assigned to said second area (12) and adapted to filter the non-visible light spectrum, preferably infrared light spectrum. Said first and second light sensitive areas (12, 14) are made on the same substrate (18) adjacent to each other to form a single integrated sensor component. An infrared light-emitting diode is placed on the substrate (18) to transmit information and/or said signals through infrared light. The invention also relates to a lamp, having such a light sensor device (10).
EFFECT: invention provides design of a light sensor which is compact, relatively cheap and easy to assemble.
