<p><P>PROBLEM TO BE SOLVED: To provide a light emitting module which can properly increase the amount emitted light by a simple construction. <P>SOLUTION: The light emitting module A has an electric circuit which is constituted so that a current flows periodically to an LED2 by repeatedly producing ON/OFF performance in a plurality of transistors Tr1, Tr2. A transistor having a constitution, wherein a base electrode connection part of a first conductivity type and a diffusion region of a second conductivity type are subjected to pn junction, is used for the transistors Tr1, Tr2. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
