| 英文摘要 | A luminescent device having a luminescent element, an optical fiber for taking up the light emitted from the luminescent element, and a package accommodating the illuminant element and receiving an end portion of the optical fiber. The optical fiber is fixed at a portion near the tip thereof by a first fixing material such that its optical coupling end opposes the light emitting region of the luminescent element, while the remainder part of the portion of the optical fiber in the package is surrounded and held by a second fixing material. By virtue of the second fixing, it is possible to avoid breakage or other defects of the fiber attributable to the difference in the thermal expansion coefficient between the core portion of the optical fiber made of quartz and a jacket of the optical fiber covering the core line portion, thus attaining a higher reliability of the illuminant device. The second fixing material also prevents water from coming into the package along the optical fiber, thereby ensuring a greater moisture-proof property of the device. |
