| 摘要 |
<p>The invention concerns a device for transmitting a light beam to zones of a surface, comprising a first mirror (10) arranged in the path of a light beam (11) derived from a first light source (9), directed perpendicularly to said surface (3) and deflecting said beam parallel to said surface; means (13) for pivoting said first mirror along an axis perpendicular to said surface, the rotating beam (14) derived from said second mirror performing a rotary scan; second mirrors (15) distributed around and spaced apart from said first mirror (10), on the path of the light beam (14), and deflecting said beam towards said surface; and means (17) for pivoting said second mirrors (15) along an axis parallel to said surface. By actuating the means pivoting said first mirror (10) and the means pivoting said second mirrors (15), the beams (20) derived from said second mirrors describe beams (22) selectively scanning said zones (2). The invention is useful for heating soldering zones of electronic components.</p> |
