Description

Multifunctional desk lamp with sitting posture prompting and myopia preventing functions

Technical Field

The invention relates to a multifunctional desk lamp for students to write, which is mainly responsible for myopia and sitting posture of children. According to survey and display, the myopia rate of China is as high as 90%, and the problems that the eyesight is damaged by electronic products and the sitting posture is very influenced are solved. The posture of reading and writing and the distance from the book table have deeper influence on the vision.

The function of desk lamp is write in the extension can have the night-light function, makes things convenient for the illumination needs at night, increases the time-recorder function, is convenient for accomplish the task in the regulation time, can set for the time suggestion rest in addition, and the prevention is near-sighted, convenient study.

Background

The correct writing posture is: straight body, head right, arm open, foot open. The body is sitting upright. The two shoulders are placed flat, the waist and the back are naturally straightened and slightly lean forward, and the chest is left and right along a fist from the table: the head is forward and slightly forward, and the distance between eyes and the paper surface is kept about one ruler; the two arms are naturally opened leftwards and rightwards, the small arm is flatly placed on a table top, the left hand presses paper, the right hand holds the pen, the pen holder is slightly inclined to the right side and is not right in front of the nose bridge, and the pen point falls right in front of the nose bridge; two feet are naturally placed on the ground and have the same width as the shoulders.

The correct writing posture can not only ensure free writing, give full play to writing skills and improve writing level, but also promote the normal development of teenagers, prevent diseases such as myopia, spinal curvature and the like, and is beneficial to health. This is also the most basic requirement for writing.

Most children do not have the control to keep the distance and the posture, and the sitting posture prompting is very important. The multifunctional desk lamp for prompting sitting postures and preventing myopia is designed based on the idea.

Disclosure of Invention

Detailed Description

The desk lamp can be selected by a function switch D: the night lamp (3) and the desk lamp (1) are used in a functional mode, or the power of the desk lamp (2) is turned off; the timer function can be selected by the function switch F;

1. when the function of the desk lamp (1) is selected for use, the writing desk lamp sitting posture prompt can be carried out, when the posture and the distance from the desk lamp are smaller than the set value of the distance sensor (C) during reading and writing, the alarm prompt is carried out, when the posture and the distance from the desk lamp are larger than the set value of the distance sensor (C), the alarm is removed, and the alarm prompt distance of the distance sensor (C) is adjustable;

The alarm prompt can be selected by an alarm selection switch (E): sound (1), light (3) and switch (2). 1. A horn (N) warning prompt is broadcasted in a voice circulation mode; 2. at night, a colorful light warning LED (K) can be selected to flash a warning prompt.

2. When the function of the night lamp (3) is selected: the desk lamp enters a night lamp mode, when a human body approaches the desk lamp at night, an LED lamp panel (G) of the desk lamp can be automatically lightened, and the desk lamp is turned off after a period of time delay; and the LED lamp panel (G) of the desk lamp is continuously lighted until the human body is delayed to be extinguished after leaving. The human body induction approaching distance and the time delay are controlled by the human body sensor (B) and are adjustable.

3. The timer function: the timer has a power switch (F), has a selection button of 'minute (M)', 'second (S)', and 'time measurement start/stop (ST/SP)', turns on the power switch (F), and displays the timer (L) on an LED. The time can be counted up and down, the accumulated time can be displayed by an LED screen, or the remaining time can be displayed. The time countdown can be set, and when the timing is finished, the buzzer (M) buzzes to give an alarm to prompt, so that the task within the specified time can be completed conveniently; and to prevent myopia, a reminder rest time may be set.

Setting a positive timing: 1. pressing the key "START/STOP (ST/SP)" to START timing; 2. any key press stops timing while "min (m)" "sec(s)", is pressed to zero.

Countdown setting: 1. setting according to MIN (M) time [ minutes ], and setting according to SEC (S) time [ seconds ]; 2. pressing the key "START/STOP (ST/SP)" to count down and START; 3. when the set time is 60 seconds, a buzzer prompts; 4. the countdown stops when any key is pressed, and the "min (m)" "sec(s)", is reset to zero.

4. The brightness adjusting function: the current flowing through the LED lamp panel (G) can be adjusted and controlled through the brightness adjusting switch (H), and the brightness of the LED lamp panel (F) is controlled.

The purpose of the technology is realized as follows:

Switching on a power supply, switching on a switch (D) to select the functions of the desk lamp, and switching off 1 desk lamp, 2 night lamp and 3;

When the desk lamp is in a function, the position of the switch (D) 1 is switched on, and by adjusting the proper distance between the desk lamp and a human body, when the sitting posture of the human body is incorrect and the front lying phenomenon occurs, the distance sensor (C) sends out a warning control signal to warn and alarm; the warning mode can select voice warning and light flashing warning through a switch (E), when the switch (E) is at the position 1, the voice warning is carried out, a voice module (I) controls a loudspeaker (N) to work, and the voice repeated reminding of sitting posture is carried out; when the switch (E) is at the position 3, the light flicker warning is carried out, the warning module (J) controls the warning lamp LED (K) to work, and the light flicker warning is carried out.

During the night-light function, switch (D) 3 position switch-on, human being close distance of human body is responded to in human body sensor (B), when human body gets into human body sensor (B) and sets for the distance within range, human body sensor (B) control LED lamp plate (G) switch-on, and the desk lamp is lighted, leaves the perception distance scope that human body sensor (B) set for until the human body to control LED lamp plate (G) time delay and extinguish, perception distance and time delay are adjustable.

When the desk lamp is in a switched-on state, the brightness of the desk lamp can be adjusted by adjusting the knob through the brightness adjusting switch (H).

The timer function is controlled by a switch (F), the switch (F) is switched on, two modes of forward timing and reverse countdown can be selected, and a buzzing prompt tone is provided.
