The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments in order to understand the invention.

1 , 2 and 3;

The invention provides a smart table lamp with a face distance measurement and a low beam reminding function, which is connected from bottom to top. The lamp holder 10, the lamp post 20 and the lamp cap 30 are provided with a main control circuit board 40. The main control circuit board 40 is provided with a main controller 401, and the lamp head 30 is provided with an LED lamp. 50;

The improvement of the present invention further includes a first distance detector 60 disposed at the front end of the base 30 for measuring the distance between the user's face and the base 30, and a front distance detector 60 disposed in front of the light pole 20. a second distance detector 70 for measuring the distance between the user's face and the lamp holder 10 at the lower end, and a pico projector 80 for projecting and outputting warning characters disposed at the upper end of the lamp post 20;

The first distance detector 60, the second distance detector 70, and the pico projector 80 are respectively connected to the main controller 401, and the light emitting direction of the pico projector 80 is opposite to the lamp holder 10. Front end;

The distance between the user's face detected by the first distance detector 60 and the base 30 and/or the user's face detected by the second distance detector 70 and the socket 10 The first distance detector 60 and/or the second distance detector 70 generate a sensing signal and transmit the sensing signal to the main controller 401 when the distance between the distances is not within the set threshold range. The main controller 401 controls the pico projector 80 to output and output an alert text according to the sensing signal.

As such, the present invention is placed on a tabletop or the like in a specific use. When the user reads or learns by using the present invention, if the user's face is close to the base 30, that is, the eye is too close to the base 30, then the eye is too close to the base 30. The first distance detector 60 generates a sensing signal and transmits the sensing signal to the main controller 401, and the main controller 401 controls the pico projector 80 according to the sensing signal. The warning output is a warning text such as "the eyes are too close to the lamp head 30, and the strong light may damage the eyes"; if the user's face is close to the lamp holder 10, that is, the eyes are too close to the book placed on the platform such as the desktop, then The second distance detector 70 generates an inductive signal and transmits the sensing signal to the main controller 401, and the main controller 401 controls the pico projector 80 according to the sensing signal. The warning output is “warning eyes too close to the book, and reading at a close distance may damage the eyes”.

In this way, the present invention has a face distance measurement and a low beam reminding function, so that the user can be urged to use the present invention healthily, and the method of outputting the warning text is more appropriate and more humanized than the traditional way of outputting the sound alarm. Therefore, the user is not disturbed to the user or scared to the user by the sudden sound of the alarm sound when the user reads the book, so that the present invention is more effective.

Further, in the specific implementation of the present invention, the main control circuit board 40 is further provided with a voice alarm module 402 for outputting a voice alarm, and the voice alarm module 402 is connected to the main controller 401;

The voice recognition module 404 is connected between the voice collection module 403 and the main controller 401, and the light control module 405 is connected between the main controller 401 and the LED lamp 50.

Thus, the present invention also has a voice control function, that is, after the user issues a voice command, the switch of the LED lamp 50 and the brightness of the LED lamp 50 can be voice-controlled, so that the remote control is turned on, off, and brightness is brightened. Or the brightness is dimmed, so that the manual control is omitted. Further, the invention is more intelligent and more convenient when used, so that the user can have a good user experience, and also makes it suitable for elderly people with limited mobility. Use at night for the night.

Here, it should be noted that when the voice control of the LED lamp 50 is required to be turned on, the corresponding voice command may be “on”, “on” or “on”, etc.; when the voice lamp is required to be turned off, the LED lamp 50 is turned off. The corresponding voice command may be “extinguished”, “off” or “good night”, etc.; when the brightness of the LED lamp 50 is required to be voice-controlled, the corresponding voice command may be “brighter” or “brightened”. Or "re-bright" or the like; when the brightness of the LED lamp 50 is required to be dimmed, the corresponding voice command may be "dark", "dark" or "re-dark", etc.;

Moreover, in the embodiment of the present invention, in the specific implementation, the main control circuit board 40 is further provided with a storage module 406 for storing user voice commands, and the storage module 406 is connected to the main controller 401. .

The control module 406 can pre-store the relevant voice command of the user, and after the user sends out the same voice command again, the user collects the voice signal through the voice recognition module 403 and recognizes it by using the voice recognition module 404. The voice command sent by the user is compared with the voice command pre-stored by the storage module 406. When the comparison result is within a preset comparison approximation range, the voice recognition module 404 identifies the success, so that Subsequent control of the LED lamp 50 is performed by corresponding voice commands.

Further, in the embodiment of the present invention, the upper end surface of the socket 10 is provided with a touch slide switch 90 for manually adjusting the brightness of the LED lamp 50, the touch slide switch 90 and the main control The units 401 are connected.
