Abstract (en)
[origin: WO2009109387A1] The invention relates to a light, in particular for obtaining a light that is similar to daylight, comprising a board (12) that houses a plurality of LED-illuminating means wherein at least one white LED and at least one coloured LED (22, 23, 24) are provided as LED illuminating means. In order to obtain a uniform spectral characteristic that can be compared to sunlight in the visible range, the light comprises a predetermined number of coloured and white LEDs (16, 17, 18, 21, 22), the colour and white LEDs (16, 17, 18, 21, 22) being combined in a predetermined manner and a predetermined power control system is associated with each LED (16, 17, 18, 21, 22).
