LIGHTING APPARATUS

摘要

The invention relates to a lighting apparatus for lighting a room with a light having a predetermined spectrum of wavelengths. The lighting apparatus comprises a plurality of positions to place light-emitting diodes and a plurality of light-emitting diodes. The light-emitting diodes are placed at the positions of the housing. A first subset of the plurality of light-emitting diodes emits light of a first colour and a second subset of the plurality of light-emitting diodes emits light of a second colour. The spectrum of the first colour is closer to the spectrum of the predetermined spectrum than the spectrum of the second colour to the predetermined spectrum. The light-emitting diodes of the first subset are placed such that at outer positions of the apparatus and the light-emitting diodes of the second subset are placed at the inner positions of the apparatus.
