<P>PROBLEM TO BE SOLVED: To provide a light emitting device in which light emitting elements can be mounted with high density while fixing the direction. <P>SOLUTION: A light emitting device 10 comprises a substrate 11 excellent in heat dissipation properties, a plurality of light emitting elements 12 mounted on the surface 11a of the substrate 11, and wiring for connecting all light emitting elements 12 on the substrate 11 in series. The plurality of light emitting elements 12 are arranged in a plurality of parallel rows 13 on the surface 11a of the substrate 11, while fixing the direction of the positive and negative electrodes of each light emitting element 12. The light emitting elements 12 in the same row 13 are connected in series by connecting the adjoining light emitting elements 12 in series through surface wiring 14 provided on the surface 11a of the substrate 11. The high potential side terminal of a low potential side row is connected with the low potential side terminal of a high potential side row between the rows 13 and 13 through backside wiring 15 provided on the backside 11b of the substrate 11, and through wiring 16 connected with the surface wiring 14 through a through hole 17 at the opposite ends of the backside wiring 15. <P>COPYRIGHT: (C)2008,JPO&INPIT |
