| 英文摘要 | PURPOSE:To improve the reliability and to facilitate the maintenance for a semiconductor light emitting device by setting some of plural light emitting elements in the halt state and actuating other light emitting elements. CONSTITUTION:The laser diodes 1a and 1b having their optical axes orthogonal to each other are used together with the condenser lenses 2a and 2d which focus the laser beam LB, a polarizing plate 3, and an optical fiber 4. The diode 1a usually emits the light, thus the beam LB radiated from the diode 1a is condensed by the lens 2a and transmitted by the fiber 4 through the plate 3. While the diode 1b is kept under the halt state and does not emit the light. Thus it is possible to improve the reliability and the lifetime and to facilitate or eliminate the maintenance for a semiconductor light emitting device. |
