<P>PROBLEM TO BE SOLVED: To provide a high output and highly efficient light emitting diode and light emitting diode lamp which are excellent in moisture resistance. <P>SOLUTION: The light emitting diode includes a DBR reflection layer and a light emitting part upon a substrate in this order. The light emitting part comprises: an active layer having a lamination structure of a well layer and a barrier layer, consisting of a composition formula (Al<SB POS="POST">X1</SB>Ga<SB POS="POST">1-X1</SB>)As(0≥X1≥1); and first and second cladding layers, consisting of a composition formula (Al<SB POS="POST">X2</SB>Ga<SB POS="POST">1-X2</SB>)<SB POS="POST">Y</SB>In<SB POS="POST">1-Y</SB>P;0≥X2≥1,0<Y≥1), which sandwich the active layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
