Fig. 3 is a hardware circuit block diagram of the head-down detection motherboard, which is divided into two parts, wherein one part is 4 laser diodes located on the emission support column 21, the other part is a slave processor 401, a power circuit 402, an NRF wireless communication module 403 and 4 infrared receivers located on the receiving support column 22, the laser diodes are connected with the slave processor 401 through a pluggable connection line, the NRF wireless communication module 403 and the 4 infrared receivers are respectively electrically connected with the slave processor 401, and the power circuit 402 supplies power to the circuits.

In this embodiment, the bow detection mainboard utilizes NRF wireless communication module to realize wireless communication with the desk lamp mainboard, and receive the button command that the desk lamp mainboard sent, thereby the luminous and corresponding infrared receiver of laser diode that the activation corresponds, if the user bow, then blocked infrared receiver, follow processor 401 this moment and convey trigger signal to the desk lamp main part through NRF wireless communication, the time of timer is opened to the host processor 301 of desk lamp, if exceed 6 seconds and still receive the bow detection signal, then self-closing light, and send out the pronunciation and remind: "desk lamp has been closed, please note sitting posture". If the user is just after sitting and raising his head, the main processor 301 resumes turning on the light. The user can keep a good sitting posture and a good head-up posture all the time. Of course, if the user does not want to use the function, the power switch of the head lowering detection main board can be turned off, or the power switch can be turned off by adopting the mobile phone APP for remote control.

In this embodiment, the user can press the keys to select one of 3 modes, i.e., automatic, manual and night light, as required.

In the automatic mode, the intelligent desk lamp can automatically adjust the brightness of the desk lamp according to the light intensity of the surrounding environment, according to the calibrated relation, the darker the light is, the brighter the desk lamp is, otherwise, the brighter the light is, the darker the desk lamp is; according to the colour temperature of current ambient temperature automatically regulated desk lamp, the temperature is higher, and the colour temperature is lower, gives other people the most comfortable lighting environment, protects eyesight, better carry out work study.

And in the manual mode, the brightness and the color temperature of the desk lamp are manually adjusted according to personal preferences and actual conditions.

Under the night lamp mode, desk lamp luminance ratio is lower, and is fixed can not adjust, and no matter there is nobody around, the desk lamp always can not close, and has closed the low head and detected the function, can use as the night light.

In this embodiment, through human infrared induction module 304, specifically whether someone around the desk lamp is responded to for pyroelectric infrared sensor, when detecting nobody around, after 60 seconds of delay, detect nobody's desk lamp meeting self-closing once more, when someone the desk lamp will open automatically, effectively reduce the electric energy waste.

In this embodiment, the height of the laser diode is set to form four low head detection alarm thresholds, which are 20cm, 25cm, 30cm and 35cm respectively. When the head of the person is lower than the selected alarm threshold, the desk lamp immediately reminds by voice: "your sitting posture is out of alignment, please raise head and put up chest! "; if the head-down posture is kept continuously, the desk lamp is automatically turned off after 6 seconds, and the lamp is turned on immediately after the sitting posture is adjusted and the head is raised. The aim is to ensure that users, particularly middle and primary school students, keep good sitting posture habit all the time, thoroughly solve the problem that parents take trouble in learning for children, eliminate myopia in a bud state, and solve diseases such as cervical vertebra and lumbar vertebra caused by long-term incorrect sitting posture. This function may be manually turned off if it is not desired in a particular situation.

In the embodiment, the desk lamp is provided with the corresponding voice reminding and broadcasting entries under the conditions of switching on and off the lamp, switching modes and unequal sitting postures, the sense of familiarity is highlighted compared with an audible and visual alarm of a buzzer, and the current desk lamp condition can be known in time.

In this embodiment, open bluetooth function and desk lamp through the cell-phone and pair and open "intelligent desk lamp" cell-phone APP of independently designing, use APP can set for desk lamp mode, bright go out, luminance and colour temperature at the range about 10 meters, to parents' learning condition that want remote control child to correct the position of sitting and play very big convenience.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
