Abstract

The invention belongs to the technical field of projectors and relates to a light shielding safety device. The device comprises a shell, a light source arranged in the shell and a reflecting prism arranged in the shell; a receding groove for light to pass through is formed in the shell; a shielding device is arranged in the shell; and the shielding device comprises an installation frame installed in the shell, a shielding plate used for shielding light and a driver used for driving the shielding plate to rotate, the driver is arranged on the installation frame, the shielding plate is installed on the driver, and when the driver drives the shielding plate to rotate to the reflecting prism, so that the light is shielded. With the light shielding safety device adopted, the situation that the eyes of a worker are injured by a projector can be reduced.

Description

technical field [0001] The present application relates to the technical field of projectors, and in particular to a light blocking safety device. Background technique [0002] At present, a projector, also known as a projector, is a device that can project images or videos onto a screen. The basic principle of a projector is to use optical components to enlarge the shape and outline of the workpiece, and then project it on the screen. It can be used The transmitted light can be used for profile measurement, and the reflected light can also be used to measure the surface shape of the closed hole. The projector is widely used in homes, offices, schools and entertainment places. [0003] When an existing projector is used, light is usually emitted by a light source, and after being refracted by a prism, the light is irradiated on an image display original to generate an image. [0004] In view of the above-mentioned related technologies, during the use of the projector, the li...
