Embodiment Construction

[0014] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the drawings in the embodiments of the present invention.

[0015] See figure 1 , figure 1 It is a functional schematic diagram of the projection device of the present invention.

[0016] The projection device 10 includes a startup module 11, a control center 12, a warning module 13, a projection module 14 and a data transmission module 15. Among them, the startup module 11, the warning module 13, the projection module 14, and the data transmission module 15 are electrically connected to the control center 12, respectively.

[0017] The start-up module 11 is used to receive an operation control instruction to start or close the projection device input by an external user, and output a corresponding start signal or a close signal to the control center 12 according to the input operation. Specifically, when the startup module 11 receives the startup operatio...

Abstract

A projection device, the projection device comprising a projection module used for emitting a projection light and performing image projection display. The projection module at least comprises a projection lens used for emitting the projection light; the projection device also projects a warning word by means of the project lens or displays the warning word by means of an electronic screen disposed on the projection device, wherein the warning word is used for reminding a user not to be in an area where the projection light is located.

Description

Technical field [0001] The present invention relates to the field of projection technology, in particular to a projection device with a safety warning function. Background technique [0002] The existing projection module is a display device for generating large-size images. The imaging principle of the projection equipment is to convert the illumination beam generated by the light source into an image beam through a light valve, and then convert the image beam into a projection beam through a projection lens, and project it onto the screen or wall. In order to achieve a better projection effect, the brightness of the light emitted by the projection device from the projection lens is relatively high, especially for the projection device that uses a laser as the light source. If the user is in the area of ​​the light emitted by the projection lens and looks directly at the projection lens, It is likely to cause damage to the user's eyes. It can be seen that promptly warning the ...
