Abstract
A table lamp capable of correcting the sitting posture of a student comprises a table lamp body and a sitting posture reminding device, wherein the sitting posture reminding device comprises a transformer, a rectifier bridge, a human body proximity sensor and an alarm, a primary side coil of the transformer is connected with a table lamp power supply, a secondary side coil of the transformer is connected with an alternating current input end of the rectifier bridge, the output end of the rectifier bridge is connected with a power supply terminal of the human body proximity sensor, and the alarm is connected with the output end of the rectifier bridge through a normally opened contact of the human body proximity sensor. According to the table lamp capable of correcting the sitting posture of the student, the human body proximity sensor is utilized to monitor the distance between the head of the student and a book in real time, when the distance is discovered to be near, alarming signals are given out to the student through the alarm, and the student is reminded to timely adjust the sitting posture. Therefore, the harm to the human body of the student caused by the bad sitting posture is thoroughly avoided, and healthy growth of the student is guaranteed.
Description
Technical field
The utility model relates to a kind of students in middle and primary schools' of being applicable to desk lamp, can in time remind the student to keep correct sitting posture, belongs to lighting technical field.
Background technology
Most of students can not keep correct sitting posture for a long time in learning process, the distance of head distance books is often less than 20cm, and this can cause very major injury to the health that the student is growing, and are to cause the major reason that student eyesight descends and cervical vertebra distorts.Although teacher and the head of a family have taked many kinds of measures to correct student's sitting posture, but there is not a kind of measure can make the student thoroughly break away from the harm of incorrect sitting-pose, therefore, how to make the student remain correct sitting posture in learning process, be the difficult problem that parents of student and school teacher face always.
The utility model content
The purpose of this utility model is the drawback for prior art, and a kind of desk lamp of correcting sitting posture of student is provided, and thoroughly eliminates incorrect sitting-pose to student's harm, guarantees the SH growth.
Problem described in the utility model realizes with following technical proposals:
A kind of desk lamp of correcting sitting posture of student, comprise desk lamp and sitting posture reminder in the formation, described sitting posture reminder comprises transformer, rectifier bridge, human body proximity sensor and alarm, and the primary coil of described transformer connects the desk lamp power supply, and its secondary coil connects the ac input end of rectifier bridge; The power supply terminal of the output termination human body proximity sensor of described rectifier bridge; Described alarm connects the output of rectifier bridge through the normally opened contact of human body proximity sensor.
The above-mentioned desk lamp of correcting sitting posture of student, described human body proximity sensor adopts microwave detector, and its model is YTMW8631.
The above-mentioned desk lamp of correcting sitting posture of student, the output of described rectifier bridge are also and be connected to filter capacitor.
The above-mentioned desk lamp of correcting sitting posture of student, described alarm are warning lamp, buzzer or audible-visual annunciator.
The above-mentioned desk lamp of correcting sitting posture of student, described alarm are installed on the lamp stand of desk lamp, and other parts of sitting posture reminder are installed in the lamp socket of desk lamp.
The utility model utilizes the distance of human body proximity sensor Real-Time Monitoring student's head and books, when finding close together, send alarm signal by alarm to the student, remind the student in time to adjust sitting posture, the harm of so just thoroughly having avoided incorrect sitting-pose that student's health is caused, thus guarantee the SH growth.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is outline drawing of the present utility model;
Fig. 2 is electrical schematic diagram of the present utility model.
Each list of reference numerals is among the figure: 1, lamp holder, 2, lamp stand, 3, lamp socket, T, transformer, ZQ, rectifier bridge, K1, desk lamp switch, K2, sitting posture reminder switch, C, filter capacitor, HS, human body proximity sensor, L1, illuminating lamp, L2, warning lamp.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model has been installed the sitting posture reminder that is made of human body proximity sensor HS, transformer T, rectifier bridge ZQ, filter capacitor C and alarm (alarm among the figure is warning lamp L2) on the basis of traditional desk lamp, utilize sitting posture reminder to remind the student to keep correct sitting posture.
Human body proximity sensor HS adopts microwave detector YTMW8631, and microwave remote sensor YTMW8631 is with microwave and the concentrated one that is used in of infrared detection technique.In control range, when only having the detector of two kinds of alarm techniques all to produce alarm signal, output alarm signal.It can keep the microwave detector reliability strong, collect again with the irrelevant advantage of thermal source that passive infrared detector need not to throw light on and brightness requirement, the characteristics that can move round the clock, greatly reduce the rate of false alarm of detector.The rate of false alarm of this compound alarm detector is more than one percent of single technology microwave alarm rate of false alarm.This sensor is the noncontact detector, not affected by temperature, humidity, noise, air-flow, dust, light etc., be fit to adverse circumstances, be widely used in the places such as automatically-controlled door control switch, safety and protection system, the picture recording control system of ATM ATM, various body of wall, glass, ATM, safety cabinet, storehouse door and window, train automatic signal.This sensor bulk is small and exquisite, can be installed in the lamp socket of desk lamp.Its major parameter is as follows:
1. microwave effective angle 360 is spent;
2. operating voltage: DC12V;
3. operating current: static 22 mA of starting state 28mA trigger maximum current: 50mA;
4. coverage: 10cm---300cm (being to be placed on the iron sheet during test);
5. output signal: normally-open normally-close;
6. environment temperature :-10 degree are to+60 degree;
7. radius of investigation: 0--5 rice is adjustable;
8. triggering output time: 2-180 second.
Action principle of the present utility model:
Referring to Fig. 2, the illuminating lamp L1 of desk lamp is electrically connected with the city through desk lamp switch K1, the civil power of alternating current 220V becomes the 12V direct current successively after transformer T step-down, rectifier bridge ZQ rectification, filter capacitor C filtering, this voltage is added on the human body proximity sensor HS, makes human body proximity sensor HS be in running status.The distance that keeps flat the books of assigned position on the table when student's head distance is during greater than setting value, and the normally opened contact of human body proximity sensor HS inside is in off-state, and alarm (being warning lamp L2 among Fig. 2) is not worked; When the distance of student's head distance books during less than preset value, the normally opened contact of human body proximity sensor HS inside is closed, and alarm sends alarm signal, reminds student's correcting sitting postures.
Alarm among Fig. 2 is warning lamp L2, also can adopt buzzer or audible-visual annunciator during implementation.Transformer T among Fig. 2 is connected with power supply by sitting posture reminder K switch 2, and sitting posture reminder still can normally move under the state that desk lamp is closed.Also transformer T directly can be attempted by on the illuminating lamp L1 of desk lamp, sitting posture reminder and desk lamp are moved simultaneously.
