<P>PROBLEM TO BE SOLVED: To provide a technique related to a two terminal LED light-emitting device that can realize the compactification and cost reduction of a light-emitting device by realizing reduction in the number of parts. <P>SOLUTION: An LED light-emitting device 10 to which an alternating current serving as a drive current is supplied via a pair of terminals 101 and 102 includes first and second LED elements 1031 and 1032 different from each other in light-emitting wavelength range. A plurality of parallel LED element groups 103 are further connected in series that are formed by connecting, by reverse poles and in parallel, the first and second LED elements 1031 and 1032 each of which are made up of one or more LED elements. <P>COPYRIGHT: (C)2012,JPO&INPIT |
