Abstract
The utility model discloses a table lamp capable of monitoring sitting postures of students, and relates to a table lamp for the students, which aims to solve the problem that the students can lie on a table surface after learning for a long time. The table lamp comprises a table lamp body, an infrared ray emission device, an infrared ray receiving device, a left frame, a right frame and a voice alarming device, wherein the lower end of the left frame is arranged on the left side of a lamp holder of the table lamp body; the lower end of the right frame is arranged on the right side of the lamp holder of the table lamp body; the infrared ray emission device is arranged at the top end of the left frame; the infrared ray receiving device is arranged at the top end of the right frame; the infrared ray receiving device is arranged opposite to the infrared ray emission device and is used for receiving infrared ray signals; both the left frame and the right frame are inclined towards one side, so that a connecting line between the infrared ray receiving device and the infrared ray emission device is deviated from the table lamp body; and a control signal output end of the infrared ray receiving device is connected with a signal input end of the voice alarming device.
Description
Technical field
The utility model relates to the desk lamp that a kind of student uses, and is specifically related to a kind of desk lamp of monitoring sitting posture of student.
Background technology
After the time that the student learns under desk lamp is long, can be owing to reasons such as fatigues, sitting posture no longer keeps rectifying state, can lie prone to desktop unconsciously.Lie prone and learn that on the table a lot of harms are arranged, the most important thing is and to cause myopia because closely read.The sitting posture of therefore supervising the student is extremely important, is starved of a kind of device that can monitor sitting posture of student automatically.
The utility model content
The purpose of the utility model provides a kind of desk lamp that can monitor sitting posture of student, lies prone to the problem of desktop to solve the long-time indoctrination session of student.It comprises desk lamp body 1; It also comprises infrared transmitting device 2, infrared receiver 3, left frame 4, left side frame 5 and phonetic alarm device 6; The lower end of left frame 4 is installed in the left side of the lamp socket 1-1 of desk lamp body 1; The lower end of left side frame 5 is installed in the right side of the lamp socket 1-1 of desk lamp body 1; Infrared transmitting device 2 is installed in the top of left frame 4, and infrared receiver 3 is installed in the top of left side frame 5, and infrared receiver 3 is oppositely arranged to receive its infrared signal with infrared transmitting device 2; Left frame 4 and left side frame 5 are all to the position that lopsidedness overhangs and makes the line between infrared receiver 3 and the infrared transmitting device 2 depart from desk lamp body 1, and the control signal output of infrared receiver 3 connects the signal input part of phonetic alarm device 6.
The student is when using the desk lamp of the utility model; Let infrared transmitting device 2 and infrared receiver 3 be positioned at the front side end of health, when the positive forward lean of sitting posture of student, the infrared ray that will cut off between infrared transmitting device 2 and the infrared receiver 3 receives relation; Infrared receiver 3 promptly sends enable signal; Phonetic alarm device 6 carries out auditory tone cues, makes the student sit back original state, lies prone to the problem of desktop thereby solved the long-time indoctrination session of student.
Description of drawings
Fig. 1 is the structural representation of the utility model, and Fig. 2 is the left side view of Fig. 1, and Fig. 3 is the electrical block diagram of the utility model embodiment two.
The specific embodiment
The specific embodiment one: specify this embodiment below in conjunction with Fig. 1, Fig. 2.This embodiment comprises desk lamp body 1; It also comprises infrared transmitting device 2, infrared receiver 3, left frame 4, left side frame 5 and phonetic alarm device 6; The lower end of left frame 4 is installed in the left side of the lamp socket 1-1 of desk lamp body 1; The lower end of left side frame 5 is installed in the right side of the lamp socket 1-1 of desk lamp body 1; Infrared transmitting device 2 is installed in the top of left frame 4, and infrared receiver 3 is installed in the top of left side frame 5, and infrared receiver 3 is oppositely arranged to receive its infrared signal with infrared transmitting device 2; Left frame 4 and left side frame 5 are all to the position that lopsidedness overhangs and makes the line between infrared receiver 3 and the infrared transmitting device 2 depart from desk lamp body 1, and the control signal output of infrared receiver 3 connects the signal input part of phonetic alarm device 6.Infrared transmitting device 2, infrared receiver 3 etc. adopt infrared ray correlation alarm just can.
The specific embodiment two: specify this embodiment below in conjunction with Fig. 1 and Fig. 3.The special character of this embodiment is: it also comprises lighting voltage adjustment circuit 7 and state switching circuit 8; Lighting voltage adjustment circuit 7 is connected on the power line 1-2 of desk lamp body 1; The signal output part of state switching circuit 8 is connected on the controlled terminal of voltage-regulating circuit 7, and the signal input part of state switching circuit 8 is connected on the control signal output of infrared receiver 3.
Lighting voltage adjustment circuit 7 can be selected digital rheostat for use; It is connected on the power line 1-1 of desk lamp body 1; After the output state of infrared ray receiving system 3 changed, the state switching circuit 8 corresponding states that switch to conducting or shutoff made digital rheostat be adjusted to corresponding resistance; Thereby change the illumination (illuminance strengthens suddenly or weakens) of desk lamp body 1 illuminator, inform that from another angle the student should sit right sitting position.Lighting voltage adjustment circuit 7 also can select for use the different resistance of two resistances as two parallel circuits; Utilize the conducting and the shutoff of triode; Switch two parallel circuits, thereby in the power supply of desk lamp, seal in different resistances, to change the different illumination of illuminating lamp.
