PURPOSE: To enable transmission of the maximum quantity of light to an optical fiber cable, by providing a header having a forward mounting surface including a front edge portion extending perpendicularly to a longitudinal axis and a rear alignment edge portion extending rearward at a predetermined compensation angle from the front edge portion, and a light-emitting device for emitting light along the longitudinal axis of the header. CONSTITUTION: A mounting stage 22 of a metal header 12 of a light-emitting apparatus 10 has a mounting plane 24 substantially parallel to a longitudinal axial line 21 of a core bar 14. The mounting plane 24 includes a front edge portion 23 extending perpendicularly to the longitudinal axial line 21 of the header 12. A rear alignment edge surface 25 extends rearward at a predetermined compensation angle 'a' from the front edge portion 23. A light-emitting diode 30 is mounted on the mounting plane 24 in such a manner that a light-emitting surface 34 thereof is linearly aligned with the rear alignment edge portion 25. The angle 'a' is predetermined to correct the angle of light emitted by the angle-stripe light-emitting diode so that the light emitted from the light-emitting apparatus 10 is substantially along the longitudinal axial line 21 indicated by an arrow 32. By accurately mounting the light-emitting diode, the maximum quantity of light may be transmitted to an optical fiber cable. |
