Abstract

The utility model discloses an energy-saving myopia prevention desk lamp which comprises a lamp holder, a lamp pole and a lampshade provided with a bulb, wherein the lamp pole is fixed on the lamp holder; the lampshade is mountedat the upper end of the lamp pole; a manual switch is arranged on the lamp holder; a metal flexible hose is fixed on the lamp holder; a photoelectric switch is fixed at the upper end of the metal flexible hose; the manual switch, the photoelectric switch and the bulb are connected to form an illuminating circuit. During the use, a probe of the photoelectric switch is adjusted to a proper position, when a user lowers the head or bends down to an unreasonable degree and the probe of the photoelectric switch cannot detect the existence of the user, the photoelectric switch transmits a turnoff signal, the energy-saving myopia prevention desk lamp is automatically turned off, and the lamp is automatically turned on after a sitting posture of the user is corrected, so that an effect of correcting the sitting posture to prevent myopia is achieved. In a similar way, when the user leaves and forgets to turn off the lamp, the lamp can be automatically turned off, and an energy-saving effect also can be achieved. Moreover, by adoption of the metal flexible hose, the position of the probe of the photoelectric switch can be optionally adjusted according to the stature of the user.

Description

Myopia prevention energy-saving desk lamp

Technical field

The utility model relates to a kind of desk lamp, is specifically related to a kind of myopia prevention energy-saving desk lamp.

Background technology

At present the teen-age rate of myopia of China occupies highly always, becomes the key factor that affect physique of the nation people, the generation of myopia and lighting environment, sitting posture and with being accustomed to etc. having substantial connection, and from these several respects, starting with is pre-myopic-preventing Main Means.The design principle of most of myopia prevention energy-saving desk lamps is to improve light source in the market, the means such as frequency conversion, LED direct current light-emitting component are luminous as adopted, coating fluorescent powder.Teenager always bows one's head gradually unconsciously and bending when study, makes the distance of eyes and books more and more nearer, and this is the main cause that causes hypometropia, and yet there are no report by the pre-myopic-preventing desk lamp correcting faulty sitting posture.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of energy-conserving and environment-protective, thereby pre-myopic-preventing myopia prevention energy-saving desk lamp can correct faulty sitting posture.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: myopia prevention energy-saving desk lamp, it comprises lamp socket, lamp stand and the lampshade that bulb is installed, lamp stand is fixed on lamp socket, lampshade is arranged on the upper end of lamp stand, and lamp socket is provided with hand switch, it is characterized in that: on lamp socket, be fixed with a metal sizing flexible pipe, the upper end of metal sizing flexible pipe is fixed with an optoelectronic switch, hand switch, optoelectronic switch and the bulb formation lighting circuit that joins.

The myopia prevention energy-saving desk lamp that the utility model provides has increased optoelectronic switch, during use, the probe of optoelectronic switch is adjusted to suitable position, both normal reading was apart from (books and eyes should be 30-35 centimetres), when user bows or bends over to reach probe that irrational degree causes optoelectronic switch and can't detect existing of user, optoelectronic switch sends pass modulating signal, myopia prevention energy-saving desk lamp is closed automatically, after user corrects faulty sitting posture, the probe of optoelectronic switch detects user's existence and just automatically turns on light, thereby reach the pre-myopic-preventing effect that corrects faulty sitting posture, with should user leaving, forget while turning off the light and also can automatically turn off the light and reach energy-conservation effect, and the utility model has adopted metal sizing flexible pipe, can regulate arbitrarily the position of probe of optoelectronic switch to meet different users's demand according to user's stature like this, the utility model also has simple in structure, novel in design, with low cost, the advantage that market prospects are wide.

As optimization of the present utility model, described optoelectronic switch is photoelectricity delay switch.When sending, optoelectronic switch closes after modulating signal, delay circuit is started working thereupon, can guarantee that like this user occurs that sitting posture is bad or away from keyboard within certain reasonably time time, myopia prevention energy-saving desk lamp can not turned off the light, can prevent like this light flash frequent injury human eye, reduce switch access times to increase its service life simultaneously.

As optimization of the present utility model, described optoelectronic switch is also integrated with phonation circuit.When the probe of optoelectronic switch, user's sitting posture to be detected bad or send prompt tone while leaving.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model one embodiment.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the circuit diagram of the utility model one embodiment.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described:

Referring to Fig. 1, Fig. 2

The myopia prevention energy-saving desk lamp that the utility model provides, the lampshade 3(bulb that it comprises lamp socket 1, lamp stand 2 and bulb is installed is in lampshade 3, do not illustrate), lamp stand 2 is fixed on lamp socket 1, lampshade 3 is arranged on the upper end of lamp stand 2, and lamp socket 1 is provided with hand switch 6, is fixed with a metal sizing flexible pipe 4 on lamp socket 1, the upper end of metal sizing flexible pipe 4 is fixed with a photoelectricity delay switch 5, and photoelectricity delay switch 5 is integrated with phonation circuit.

Referring to Fig. 3

Hand switch 6, photoelectricity delay switch 5 and the bulb 7 formation lighting circuit that joins.

In conjunction with Fig. 1, Fig. 2, Fig. 3 is visible, during use after closed hand switch 6, photoelectricity delay switch 5 starts working, user only need to be according to self stature, the probe of photoelectricity delay switch 5 51 is adjusted to suitable position, both normal reading was apart from (books and eyes should be 30-35 centimetres), after turning on light when user bows one's head and bending reaches probe 51 that abnormal distance causes photoelectricity delay switch 5 and can't detect existing of user, photoelectricity delay switch 5 sends and closes modulating signal and send prompt tone, the delay circuit of photoelectricity delay switch 5 (time is adjustable) is started working thereupon, if user fails timely correcting sitting postures in setting-up time, electric delay switch 5 disconnects, automatically turn off the light, thereby reach the pre-myopic-preventing object of correcting sitting postures, with should user leaving, forget while turning off the light, can automatically turn off the light in time and point out equally, play energy-conservation effect.And work as user's correcting sitting postures or get back to before lamp, the probe 51 of the photoelectricity delay switch 5 on myopia prevention energy-saving desk lamp detects user's existence automatically, and electric delay switch 5 is connected, and myopia prevention energy-saving desk lamp can be turned on light at once automatically.

The utility model optoelectronic switch can be optic fiber photoelectric switch etc., as the commercially available model photoelectricity delay switch that is cnz-gdcfds.

Be to be understood that example as herein described and embodiment are only in order to illustrate, those skilled in the art can make various modifications or variation according to it, all belong to protection domain of the present utility model.
