FIELD: electricity.
SUBSTANCE: lighting device in this invention includes multiple point sources 32 of light and a conducting pattern 34. Each of point sources 32 of light includes two electrodes 33a, 33b, having different polarities, and point sources 32 of light are set in multiple matrices 40 of light sources, every of which includes a predetermined number of point sources 32 of light, and excitation energy is sent to each matrix 40 of light sources. Adjacent matrices 40 of light sources are made up so that a point source 32 of light of one of adjacent matrices 40 of light sources is opposite to a point source 32 of light of the other one from adjacent matrices 40 of light sources, with each of electrodes 33a, 33a, opposite one to another. Opposite electrodes 33a, 33a are arranged so that they have identical polarity and are connected with the same conducting pattern 34.
EFFECT: in a lighting device sources of light are arranged evenly and closely between each other, in order to improve brightness of lighting and achieve heterogeneous distribution of lighting brightness.
