Abstract
The utility model provides an electronic vision protector which is installed on legs of glasses for personal use and is composed of a shell, an infrared distance measurement element, a photoelectric pipe, a luminous diode, a power switch, a slight contact switch, a battery cover, a control circuit, a battery, etc., wherein, the control circuit comprises a distance measurement circuit, a photic measurement circuit and a delayed circuit. When a wearing person studies, if the distance of eyes and a book can not maintain about a foot, the prompt of a corresponding photic signal can be obtained in time when the person continuously read the book for more than an hour and rays are too strong or too weak. Thereby, the utility model helps to protect vision.
Description
This utility model relates to a kind of electronic eyesight protecting unit for individual's use.
Common on the market electronic visual protector has " look and protect desk lamp " and " look and protect writing case " two kinds now.The both has used a pair of feeler that is parallel to each other and stretches out to the front upper place; infrared emission tube is equipped with at a feeler top; the infrared receiver tube that the infrared beam that it sends is loaded on another feeler relative position receives; when infrared beam was blocked, protector will send sound warning signal.The feeler user head both sides that are placed in, and adjust to the appropriate location, just can help user to make eyes and books keep distance about a chi.But this adjustment is cumbersome, and the feeler that stretches out forward is also dangerous to user, and when using in public places such as classrooms, the alarm sound that sends can influence other people.Though the electronic eyesight protecting unit of some kind also has other defencive function,, have all that volume is big, price is expensive and problem such as use inconvenience as reminding in limited time and ambient light is too weak reminds etc.
The purpose of this utility model is: design little, in light weight, the easy to use and low-cost electronic eyesight protecting unit of a kind of volume.
Technical solution of the present utility model is: a kind of electronic eyesight protecting unit that uses for the individual on the eyeglasses temple arm that is installed on; form by shell, infrared distance measuring element, light emitting diode, control circuit, battery and on and off switch; it is characterized in that: the infrared distance measuring element is positioned at the front end face of electronic eyesight protecting unit; light emitting diode is positioned at the inboard of electronic eyesight protecting unit first half, and comprises range-measuring circuit in the control circuit.When user in when study, if can not keep suitable distance between eyes and books, light emitting diode just sends optical signal and reminds.
Can add light measuring circuit in control circuit of the present utility model, photometry element is positioned at the front end face of protector, and the reflection ray of books is surveyed when reading, when light too by force or when too weak, light emitting diode just sends optical signal and reminds.
Can in the system circuit of this utility model control, add delay circuit, when user in when study, if reading surpasses one hour continuously, light emitting diode just sends optical signal and reminds.
The utility model has the advantages that: the detection direction and the direction of visual lines of range finding element and photometry element are consistent, can obtain distance and intensity of illumination information more accurately, its detection accuracy is guaranteed by control circuit, does not need frequent adjustment, convenient and safety during use.The light alerting signal that light emitting diode sends is informed user by the surplus light of eyes, also can not influence other people in public places such as classrooms.By using integrated circuit and surface mounting technique to make, can increase function and reduce volume and weight.Because simple in structure, production cost is lower.
Talk an embodiment below in conjunction with accompanying drawing.
Fig. 1 is stereoscopic figure of the present utility model.
Fig. 2 is installed on state on the eyeglasses temple arm for this utility model.
Fig. 3 is control circuit figure of the present utility model.
The electronic eyesight protecting unit of in Fig. 1 and Fig. 2, describing; one cabinet 1 is arranged; in the ranging window 2 of shell front end face the infrared distance measurement element is housed; in the photometry window 5 of shell front end face photocell is housed; light emitting diode is contained in the inboard display window 3 that protrudes of glasses, also has on and off switch 4, touch switch 6, battery cover 7, internal control circuit and battery.
In the circuit that Fig. 3 describes, IC
1Model is HC800, D
1Be infrared light emitting diode, D
2Be infrared receiver diode, in order to reduce number of parts, D
1And D
2Can replace with infrared ray launches and receives pipe, should select the element of reflection coverage more than 40 centimetres for use.Work as D
1After the infrared ray of emission is reflected by books, if by D
2Receive IC
1Just control LED
1Luminous, by variable resistance W
1Circuit sensitivity is regulated, can be at user eye and books distance LED during less than 33 centimetres
1Just luminous.Circuit with identity function is used in electronics hand dryer, infrared switch and the active infra-red burglar alarm, can be used to replace.IC
2Model is F3SO5, D
3Be photodiode, D
3If change phototriode into, the sensitivity meeting improves a lot.Work as D
3When detecting intensity of illumination greater than 200 luxs or less than 150 luxs, IC
2Control LED respectively
2Or LED
3Luminous, can pass through variable resistance W
2And W
3Circuit sensitivity is regulated, and the circuit with identity function is used in the light measuring circuit of photographing unit.IC
3Be 555 time-base integrated circuits, this integrated circuit is widely used, and here, it is used in the restriction delay circuit of reading time.When user is read a book above one hour continuously, IC
3The control LED
4Luminous, click setting switch K (6 in the accompanying drawing 2), circuit just restarts work in limited time.
In order to make optical signal eye-catching, LED
1, LED
2, LED
3And LED
4Should select high brightness LED and flicker light emitting diode for use, and be distinguished with different colours.Battery uses button cell or light cell.If display window 3 and interior light emitting diode thereof and shell flexibly connect with flexible cord, just can be put in more showy position to display window 3 easily, but protector structure is complicated, manufacture difficulty increases.After protector is loaded onto sounding component and related circuit, just can remind with acoustical signal, in order not influence other people, should use earplug or lead flexible pipe, but user have sense of discomfort, it is also not too convenient to use.After loading onto attitude transducer and circuit, also can remind incorrect posture.
According to the practical situation and the personal like of each glasses, can be installed on vision protector the outside of the left side or the right mirror lower limb, display window is positioned at mirror lower limb upside or downside, and Fig. 2 is the situation that is loaded on the left side.On the mirror lower limb, select one and do not block ranging window 2 and photometry window 5, and see display window 3, also can not influence the position of glasses folding, with glue vision protector and mirror lower limb are cemented then with the surplus luminous energy of eyes.Can also be made of one vision protector and eyeglasses temple arm in actual applications, perhaps on the vision protector shell, load onto the fixture that can adapt to different glasses situations.
