Adaptive luminous intensity distribution of LED luminaires

A luminaire with a light emitting surface comprising an array of light sources, the luminaire further comprising:

• a LED driver, the array of light sources being connected in series with the LED driver;
• a light output tuning unit connected to a certain set of light sources within the array and being able to tune a light output of said certain set of light sources;
• an interface adapted to be operated during an installation or commissioning of the luminaire before normal operation of the luminaire, the interface adapted for receiving configuration information at least comprising dimming information;
• and
• a control unit, for fixing the tuning unit according to the received configuration information during normal operation of the luminaire;
• wherein the light emitting surface is a planar surface forming said light emitting surface, said certain set of light sources is on at least one edge of the planar surface and
• wherein said array of light sources is rectangular and is connected to the LED driver and the light output tuning unit comprises a dimming circuit adapted to dim said certain set of light sources, said dimming circuit including at least one shunt switch adapted to shunt said certain set of light sources off from or on to the LED driver, wherein said certain set of light sources are at two connecting edges of the array, the dimming circuit includes two shunt switches, wherein one of the two shunt switches is in parallel with said certain set of light sources and adapted to bypass or not bypass said certain set of lights sources from the driver and the other one of the two shunt switches is in parallel with a subset of said certain set of light sources that are placed in one of the two connecting edges.
