Embodiment Construction

[0045] see figure 1 and figure 2 Shown are the functional block diagram and schematic diagram of the first preferred embodiment of the eye protection device of the present invention, respectively. The eye protection device 1 can be applied to an optical instrument 2, and the optical instrument 2 can be an optical instrument that can emit a strong light beam such as a projector, a laser pointer, or a measuring device; in this embodiment, the optical instrument 2 will use a projection machine as an example.

[0046] The optical instrument 2 has a visible light source 21 and a scanning mirror component 22 . The visible light source 21 can emit at least one visible light beam 3, and the visible light source 21 and the scanning mirror element 22 are optically coupled (optically coupled), which means that the scanning mirror element 22 is positioned at the light of the visible light beam 3 emitted by the visible light source 21. Therefore, the visible light beam 3 emitted by the...

Abstract

A device and method, which are utilized in an optical apparatus, for protecting eyes are disclosed. The optical apparatus includes a scanning-mirror component and a visible light source which is optically coupled to the scanning-mirror component. The optical apparatus emits a visible light beam to the scanning-mirror component by using the visible light source. The scanning-mirror component then reflects the visible light beam to emit the visible light beam to a scanning region. The device and the method for protecting eyes can determine at least one eye region in the scanning region, and then make the optical apparatus stop emitting the visible light beam at least within the eye region.

Description

technical field [0001] The present invention relates to an eye protection device and method, in particular to an eye protection device and method for optical instruments. Background technique [0002] Some optical instruments, such as optical instruments for measurement or optical equipment for projection, emit a bright beam of light to a specific area. If the user's eyes accidentally enter the specific area, the user's eyes may be uncomfortable or even injured due to being irradiated by the light beam. If the light beam is a laser beam, it is more likely to cause blindness to the user. [0003] In view of this, it is an urgent problem to be solved in the industry to provide an eye protection device or method applicable to optical instruments so as to protect users' eyes from being injured by the strong light of the optical instruments. Contents of the invention [0004] The main purpose of the present invention is to provide an eye protection device and method, which ca...
