ABSTRACT:
A light-beam heating apparatus utilizes light energy effectively by having a light emitting portion of a radiating lamp coincide with a first focal point of an ellipsoidal reflecting mirror automatically and with high accuracy Light intensity and positional information at a light receiving end of an optical fiber are detected by means of a photodetector, a light intensity signal converted by a photoelectric converter is inputted to an arithmetic drive circuit, a drive mechanism of a radiating lamp fitting mechanism is actuated, the light emitting portion of the radiating lamp is moved in the X-axis direction, the Y-axis direction and the Z-axis direction successively in a direction that the light intensity increases, a central axis of a distribution of light condensed by an ellipsoidal reflecting mirror and a central part of the light receiving end of the optical fiber are made to always coincide with each other so as to utilize the light energy effectively. The light energy incident to the optical fiber is computed from a light intensity signal and a detected position, and a lamp current is controlled so as to make the error with respect to an indicated value of a command circuit smaller, thereby to stabilize the light radiation energy at a predetermined value.
