Abstract

The present application relates to the technical field of projectors, in particular to a light-shielding safety device, which includes a housing, a light source disposed in the housing, and a reflective prism disposed in the housing. A shielding device is provided in the body, and the shielding device includes a mounting frame installed in the housing, a shielding plate for shielding light, and a driver for driving the shielding plate to rotate. The driver is arranged on the mounting frame, and the shielding plate is installed on the driver. When the driver drives the baffle plate to rotate to the reflective prism, the light is blocked. The present application has an effect of being able to reduce the occurrence of situations where the projector causes damage to the eyes of workers.

Description

technical field [0001] The present application relates to the technical field of projectors, and in particular, to a light shielding safety device. Background technique [0002] At present, the projector, also known as the projector, is a device that can project images or videos onto the screen. The basic principle of the projector is to use optical components to enlarge the shape and outline of the workpiece, and then project it onto the screen. Transmitted light can be used for profile measurement, and reflected light can also be used to measure the surface shape of non-through holes. Projectors are widely used in homes, offices, schools and entertainment places. [0003] When an existing projector is used, usually a light source emits light, which is refracted by a prism to irradiate the light on the original image display element, thereby generating an image. [0004] In view of the above-mentioned related technologies, during the use of the projector, the light from th...
