The present embodiment desk lamp also includes warning device 5 and control device 7.Warning device is alarmed to send cue
Device is audio alarm device, it is preferable that using buzzer or loudspeaker, by sending alarm sound or playing advance typing
The mode of voice, corrected faulty sitting posture so as to send cue prompting user.
Control device respectively with the first sensor, second sensor, the first infrared distance measurement module, the second infrared distance measurement
Module, warning device are electrically connected with, for obtaining the first sensor, second sensor, the first infrared distance measurement module, second
The data and the body posture data of calculating user that infrared distance measurement module is detected, and to control the warning device to send
Cue.
The first infrared distance measurement module drive connection has the first actuating unit 23, and first actuating unit is used to drive
First infrared distance measurement module rotates in perpendicular；The second infrared distance measurement module drive connection has the second engine
Structure, second actuating unit 33 are used to drive second infrared distance measurement module to rotate in perpendicular；Described first is dynamic
The control device is electrically connected in force mechanisms, the second actuating unit.First actuating unit and the second actuating unit include
Numerical-control motor.
As the further optimization to the present embodiment, in addition to uniformly several indicator lamps 6 on the base, use
To indicate the illumination scope of operation center position of the lamp body, the indicator lamp is electrically connected with the control device.
As the further optimization to the present embodiment, in addition to the man-machine interaction unit being electrically connected with the control device
8, to export user's attitude data, intensity of illumination data and the default illumination intensity value of input.The man-machine interaction unit is also
Including the key group to input and to show the LCD display of user's body posture data.
In the operating condition, when user carries out operation using desk lamp of the present invention, first sensor and second sensor
Work, the rotational angle data of support and lamp stand are detected, and sent to control device；Control device is for support, lamp stand
Rotational angle data and lamp stand, support its length data are calculated, and calculate the scope and plane of illumination central point of plane of illumination
Position.Now, the indicator lamp that the plane of illumination center is corresponded on base starts, and sends corresponding illumination and points out illumination center
Position.
The first infrared distance measurement module is rotated under the effect of the first actuating unit simultaneously, does not stop to change infrared sensing measurement
Direction, so as to detect the distance A1 and user's body of the head most distant point of user and the first infrared distance measurement module
With the distance A2 of the first infrared distance measurement module, and A1 and A2 are sent to control device.
Meanwhile second infrared distance measurement module rotated under the effect of the second actuating unit, do not stop to change infrared sensing measurement side
To so as to detect the distance of the illumination scope of operation, if occurring work body in the illumination scope of operation, the second infrared distance measurement module is felt
Deviation occurs in the distance that should be arrived, and can calculate the height B of work body according to this deviation, and the second infrared distance measurement module can be with
Detect the near distance spot on user head and the distance C of the second infrared distance measurement module.
According to A1, A2 and stent length, holder pivots angle, pole lengths and lamp stand rotational angle data, can push away
Calculate user's operation posture whether specification.And according to B and C can extrapolate user's head distance work body upper surface it
Between distance, judge user whether too close to work body.And according to A1, A2, B, C and stent length, holder pivots angle
Degree, pole lengths and lamp stand rotational angle data, control device can set up the attitude data model of user, and send to people
Machine interactive interface, the attitude data of user is shown, form intuitively data message and send to LCD display.Further,
User's operation posture normative model, and default certain error range can be preset in control device, detection is calculated
User's actual job attitude mode compared with default user's operation posture normative model, so as to judge user's
Whether operation posture and user head meet specification with work body distance, facilitate warning device to remind user to pay attention to operation appearance
State.
Specifically, the near distance spot on the user head be infrared distance measurement module in mensuration distance, user from
A bit of infrared distance measurement module recently；Accordingly, the most distant point on the user head is that infrared distance measurement module is determining
In distance, user it is farthest from infrared distance measurement module a bit.In the present embodiment, what the first infrared distance measurement module was determined makes
The near distance spot on the user head that the most distant point on user head is determined with the second infrared distance measurement module is approximately phase
Same point.
Specifically, if the operation posture of user is incorrect, i.e., the body of user as shown in Figure 2 is excessively bent, and first
Infrared sensing range finder module detects user's body the first infrared sensing of distance range finder module too far, and user head and the
One infrared sensing range finder module distance belongs to specification distance, you can judges that the operation posture of user is lack of standardization, body is excessively askew
Song, control device control warning device send cue, prompt user to be corrected.Similarly, when user head excessively
During close to work body, the second infrared distance measurement module is according to the work body height B and user head the near distance spot of detection and the
Distance C between two infrared distance measurement modules, and compared with preset distance, you can judge user head and the spacing of work body
From excessively near, warning device will send cue.
By detecting the distance between user head and the first infrared module data, user head and the second infrared mould
The distance between the distance between block data, user's body and the first infrared module data, the second infrared module and work body
Range data, support, the length data of lamp stand between surface, and the data that each sensor is detected, control device can calculate
Go out the attitude data of user, so as to judge whether user's posture meets specification, reach the purpose of correction user's posture, survey
Amount is accurate, and human body will not be damaged, and being generally applicable to student, white collar etc. needs the crowd of long working.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
