Abstract
A kitchen unit (200), for example an extraction hood, has a task lighting system (100) for illuminating an operative area (210) below the kitchen unit, the task lighting system comprising:—at least a plurality of fixed lighting elements (110) configured to generate, on the operative area, corresponding fixed elementary light spots (270) and macro light spots (280) by the union of the elementary light spots; and—a control unit (115) configured to receive a spot position signal indicative of a desired position of a macro light spot and to selectively activate, based on the spot position signal, the lighting elements to generate a macro light spot with said desired position.
Claims15
Kitchen unit (200) having a task lighting system (100) for illuminating an operative area (210), the task lighting system being characterized in that it comprises:
- at least a plurality of fixed lighting elements (110) configured to generate, on the operative area, corresponding fixed elementary light spots (270) and macro light spots (280) by the union of the elementary light spots;
- and
- a control unit (115) configured to receive a spot position signal indicative of a desired position of a macro light spot and to selectively activate, based on the spot position signal, the lighting elements to generate a macro light spot with said desired position.
Kitchen unit according to any of the preceding claims, further comprising an input interface (135) configured to receive commands from a user and to generate corresponding signals for the control unit including at least said spot position signal.
Kitchen unit according to any of the preceding claims, wherein the control unit is further configured to set light features of a macro light spot by setting light features of the activated lighting elements.
Kitchen unit according to any of the preceding claims, wherein the control unit comprises a plurality of drivers (125j) configured to selectively enable/disable electric power delivery to corresponding lighting elements or groups of lighting elements to selectively activate/deactivate lighting elements or groups of lighting elements.
Kitchen unit according to any of the preceding claims, wherein each lighting element comprises at least an electric light source (240) and an optical element (245).
Kitchen unit according to any of the preceding claims, wherein the lighting elements of a plurality are arranged according to a matrix.
Kitchen unit according to any of the preceding claims, wherein the task lighting system comprises at least two lighting units (105) each comprising a plurality of lighting elements, said lighting units being positioned on different parts of the kitchen unit to illuminate adjacent portions of the operative area.
Kitchen unit according to any of the preceding claims, wherein the kitchen unit is a kitchen air extractor hood (200) and wherein the operative area is an area under the extractor hood.
Method for illuminating an operative area below a kitchen unit, the kitchen unit being provided with at least a plurality of fixed lighting elements configured to generate, on the operative area, corresponding fixed elementary light spots and macro light spots by the union of the elementary light spots, the method being characterized in that it comprises the step of selectively activating, based on a spot position command indicative of a desired position of a macro light spot, the lighting elements to generate a macro light spot with said desired position.
