| titleOfInvention |
Light-emitting diode, light-emitting diode lamp, and illumination device |
| abstract |
The invention provides a light-emitting diode, a light-emitting diode lamp, and an illumination device which emit infrared light with both high-speed response and high output performance. The invention relates to a light-emitting diode including a light-emitting portion which has an active layer of a quantum well structure, in which a well layer made of a compound semiconductor having a composition formula (In X1 Ga 1-X1 )As (0≦X1≦1) and a barrier layer made of a compound semiconductor having a composition formula (Al X2 Ga 1-X2 )As (0≦X2≦1) are alternately laminated, and a first clad layer and a second clad layer sandwiching the active layer, an electric current diffusion layer which is formed on the light-emitting portion, and a functional substrate which is bonded to the electric current diffusion layer, a light-emitting diode lamp, and an illumination device. The first and second clad layers are made of a compound semiconductor having a composition formula (Al X3 Ga 1-X3 ) Y1 In 1-Y1 P (0≦X3≦1, 0<Y1≦1), and when a single well layer and a single barrier layer form a single paired layer, the number of paired layers is equal to or smaller than 5. |
