Shaving or hair trimming device |
| 摘要 |
A device for projecting an elongate optical image (7) onto a surface (5) is disclosed. The device has an optical element (8) with a reflective surface (11) configured to reflect a beam of light emitted by a light source (9) so that the beam of light (12) converges in a first plane (X-Y) and diverges in a second plane (Y-Z), the first plane being at right angles to the second plane. |
