PORTABLE LASER PROJECTOR WITH AN EYE PROTECTION DEVICE AND METHOD FOR PROTECTING AGAINST LASER LIGHT

摘要

The present invention relates to a portable laser projector equipped with an eye protection device for protection from laser light generated by projection means, the eye protection device comprising a micromechanical acceleration sensor for detecting a gravitational acceleration component, the detected It is designed to generate an orientation signal based on the gravitational acceleration component, and to control the projection means according to the generated orientation signal. Further, the present invention relates to a method for protecting from laser light generated by a portable laser projector, wherein the laser projector uses laser light emitted by the projection means of the laser projector within an open angle range around the main projection direction. Is designed to generate a projected image, and in the first method step, a gravitational acceleration component is detected, and in a second method step, an orientation signal is generated according to the orientation angle between the main projection direction and the horizontal plane and according to the detected gravitational acceleration component, In the third method step, the projection means is controlled based on the generated orientation signal.
