The invention relates to copying light conditions from one location and pasting into or providing similar light conditions to another location in a lighting system. A light detector () is provided which comprises a first sensor () configured to receive a first light directly from a first light source () and measure first light attributes of the first light, and a second sensor () configured to receive the first light influenced by reflections from surfaces () and measure second light attributes of the first light. Processing means () are adapted to process perceivable light attributes at the first location () from the first light attributes and the second light attributes, and in conjunction with the specification of the second light source () to control the second light source () to provide the second light having light attributes at the second location () that substantially match the perceivable light attributes at the first location (), whereby the illumination at the first location () may be copied and pasted to the second location ().

System and method for performing an illumination copy and paste operation in a lighting system

Controlling a lighting system, which comprises a controller (), lighting units (), and a sensing device. Each lighting unit comprises a lighting source () and a modulated light source (). A single light source may be used to function as both the lighting source and the modulated light source. Each modulated light source emits uniquely modulated light. A radiation pattern of each modulated light source coincides substantially with a radiation pattern of a lighting source of the same lighting unit. The sensing device is suitable to sense modulated light in a viewing area. Lighting units from which the sensing device senses modulated light are identified from the modulation of that modulated light. The sensing device measures the intensity of the modulated light from the identified lighting unit. The lighting sources are controlled dependent on control data which comprises measuring values of measured light intensities.
