Description
Technical Field
The invention relates to the field of lamps, in particular to a myopia prevention and control eye-protection desk lamp and a control method.
Background
The desk lamp is small and exquisite, conveniently carries, and this electrical apparatus is mainly placed on desk or dining table for the usefulness of illumination, and the bright irradiation range of desk lamp is comparatively little and concentrated relatively. The desk lamp mainly has the decoration effect, the light of the whole room cannot be influenced, the effect is limited around the desk lamp, and the desk lamp is convenient to read, learn, work and save energy. With the increase of working and learning pressure of people, particularly the increase of heavy learning task and rising learning pressure of teenagers, students in middle and primary schools in the growth and development period learn by leaning on a desk lamp for a long time, often study for a long time to influence or damage the development and eyesight of the students, myopia problems are generally caused, the overall myopia incidence situation of the teenagers is severe, and the myopia problems in low-age groups are prominent. In primary and middle school stages, myopia rates increase rapidly with increasing grade. Once the myopia of the teenagers of the children is cured under the current medical and technical conditions, the myopia is most important to prevent the formation and development of the myopia, so that a plurality of eye-protecting desk lamps are present on the market.
The existing eye-protection desk lamp usually protects the eyesight by adjusting the sitting posture of a user or achieves the eye-protection function by adjusting the uniformity, brightness, stroboscopic degree and the like of lamplight, for example, patent CN107990188A discloses an eye-protection LED desk lamp, a milky semitransparent liquid is arranged in a hollow interlayer of a lamp cover, after the semitransparent liquid is added, the light emitted by a lamp bead is dispersed, the brightness of the lamp bead is reduced, and therefore, even if eyes directly look at a lamp body, the eyes cannot feel dazzling. However, these approaches have limited eye protection. Therefore, it is important to study a desk lamp that can achieve both illumination and direct eye protection.
Disclosure of Invention
The present invention is directed to overcoming at least one of the above-mentioned drawbacks (shortcomings) of the prior art, and providing a desk lamp and a control method for preventing and controlling myopia, which are used for protecting eyesight of a user of the desk lamp.
The invention aims to provide a myopia prevention and control eye-protection desk lamp, which comprises a lamp holder and a support rod, wherein one end of the support rod is connected with the lamp holder, the other end of the support rod is provided with an illumination light source, the support rod is provided with a far infrared light source, the irradiation surface of the far infrared light source faces the using side of the desk lamp, and the far infrared light source is movably connected with the support rod; the desk lamp further comprises a controller, wherein the controller is electrically connected with the illumination light source and the far infrared light source, and the controller is used for controlling the illumination light source and the far infrared light source to be alternatively turned on.
The lamp holder is used for stabilizing the supporting rod and the light source; the support rod is used for supporting the light source and connecting the light source to the base; the illumination light source is used for daily illumination, and the illumination face is downward; the far infrared light source is used for protecting the eyesight of a user, if the irradiation surface of the far infrared light source is downward, the far infrared light source which truly enters eyes of the user and acts on eye tissues is less, and the effect on the eyes is very limited, so that the irradiation surface of the far infrared light source faces towards the use side, and the user can receive more far infrared light sources; the far infrared light source can rotate relative to the support rod so as to adjust the angle of the irradiation surface of the far infrared light source relative to the support rod; the controller is used for controlling the on and off of the illumination light source and the far infrared light source, and when the illumination light source is on, the far infrared light source is off; conversely, when the far infrared light source is on, the illumination source is off.
The illumination light source emits illumination light beams, so that the desk lamp has a normal illumination function; the far infrared beam can promote the repair and regeneration of retina cells, and protect the vision from the tissue of the eye, so as to achieve better eye protection effect; the irradiation surface of the far infrared light source faces the use side, so that more far infrared light beams can directly enter eyes of a user, and the vision is protected; the far infrared light source can rotate relative to the support rod, and a user can adjust the angle of the far infrared light source relative to the support rod until the angle is right opposite to the eyes of the user, so that the users with different heights can fully utilize the far infrared light source to protect the eyes; the illumination light source and the far infrared light source are arranged separately, and are alternatively started, so that illumination and eye protection are not interfered with each other, the illumination effect and the eye protection effect of the desk lamp are guaranteed, meanwhile, the two light sources can be automatically switched through the controller, one of the two light sources is not required to be manually turned off, and the desk lamp is convenient to use.
Further, the bracing piece is including the last bracing piece and the lower bracing piece that slope set up, go up bracing piece and lower bracing piece and form and rotate the connection, the upper end of going up the bracing piece is close to the user side and the lower extreme is to keeping away from the user side slope, the upper end of lower bracing piece is kept away from the user side and the lower extreme is to the user side slope.
The upper end of the upper supporting rod is connected with the illumination light source, the lower end of the upper supporting rod is connected with the lower supporting rod, the upper end of the lower supporting rod is connected with the upper supporting rod, and the lower end of the lower supporting rod is connected with the base. The joint of the two support rods is in rotary connection so as to realize the height and position adjustment of the illumination light source, thereby adjusting the illumination area of the illumination light beam until the illumination brightness required by a user is reached; meanwhile, the relative position adjustment of the illumination light source and the far infrared light source can be realized through the arrangement of the rotary connection, if the height of a user is higher, when the far infrared light source is used, the relative position of the two light sources can be adjusted, so that the sight of the user cannot be blocked by the illumination light source, the mutual influence of the two light sources is further reduced, and the applicability of the desk lamp is improved.
The inclined arrangement of the upper support rod and the lower support rod enables the two support rods to form a V shape with an opening facing the use side. When the far infrared light source is used, the far infrared light source is usually required to irradiate obliquely upwards, if the lower support rod is vertical or the upper end of the lower support rod is inclined to the using side, and when the far infrared light source is rotationally adjusted, the upper edge of the far infrared light source is clamped by the lower support rod, so that the angle adjustment of the light source is limited. Therefore, the upper end of the lower supporting rod is inclined away from the use side, namely an included angle space is formed between the lower supporting rod and the vertical direction, so that the angle adjustment of the far infrared light source in the inclined upper direction is facilitated. The upper end of the upper supporting rod is inclined towards the using direction, so that the irradiation surface of the illumination light source can extend out of the upper side of the lower supporting rod, and more illumination light can be directly irradiated on the using area of the desk lamp placing platform instead of the supporting rod.
Further, a lamp housing is arranged on the far infrared light source, a rotary switch is arranged between the lamp housing and the lower support rod, the rotary switch is electrically connected with the controller, and the lamp housing is in rotary connection with the lower support rod through the rotary switch.
The lamp housing is used for protecting far infrared light sources and playing a role in dust prevention. The rotary switch is arranged between the lamp shell and the lower support rod, and sends an instruction to the controller through the rotary lamp shell, so that the far infrared light source is turned on and off, and the control switch of the far infrared light source is not required to be arranged on the desk lamp, so that the whole desk lamp is more concise and attractive. The rotary switch can be a knob switch as long as the lamp shell can be rotated to control the on and off of the far infrared light source, or the rotary switch can be a combination of the rotating shaft assembly and the micro switch.
Further, the shape of the lamp shell is matched with that of the lower support rod, and when the far infrared light source is closed, the lower support rod is overlapped with the lamp shell to form a whole.
The shape of the lamp housing is matched with that of the lower support rod, for example, when the shape of the lower support rod is cuboid, the shape of the lamp housing is cuboid. Because the shape matches, when far infrared light source closed, the lamp body just rotates to the front that can block the bracing piece, so realize when need not to use far infrared light source, the lamp body can overlap with the lower bracing piece, can not stretch out the left and right sides of lower bracing piece, reduces the impaired probability of collision, prolongs its life, makes the desk lamp whole more pleasing to the eye simultaneously.
Further, the irradiation surface is in a long strip shape, the length of the irradiation surface is 8-14 cm, the width of the irradiation surface is 2-5 cm, and when the far infrared light source is started, the long side of the irradiation surface is in a horizontal state.
The size of the irradiation surface is matched with the length and width of eyes of a human body, the extension parts of the two sides of the lower support rod can be long when the length is too long, the irradiation surface is easy to collide and damage, meanwhile, far infrared light absorbed by the eyes is limited, and the irradiation surface is too long or too wide, so that the far infrared light is wasted. When the far infrared light source is started, the long side of the irradiation surface is in a horizontal state, namely the long strip irradiation surface is in a transverse state, so that the position and the shape of the eyes of a human body are met, more far infrared light sources can directly enter the eyes of a user, and the utilization rate of the far infrared light sources and the eye protection effect are improved.
Further, a timer is arranged in the controller, a face recognition system and a distance measuring system are arranged on the supporting rod, the face recognition system is used for detecting the eye looking position of a user, the distance measuring system is used for detecting the distance between the user and the far infrared light source, and the timer, the face recognition system, the distance measuring system and the far infrared light source are electrically connected.
The timer is used for controlling the irradiation time of the far infrared light source, and based on the relation between the far infrared light and eye tissues according to the biological principle, a user can set the irradiation time by himself, so that the eyes can be protected more effectively.
The face recognition system detects whether eyes of a user face the far infrared light source or not, the distance measuring system detects whether the distance between the user and the far infrared light source accords with a preset value or not, and the eyes of the user face the position and the distance between the user and the far infrared light source control the starting and stopping of the timer timing. Further, when the face recognition system detects that the user looks at the far infrared light source and the distance measurement system detects that the distance between the user and the far infrared light source is within a preset value, the timer starts to count; when eyes of a user do not look at the far infrared light source or the distance between the user and the far infrared light source exceeds a preset value, the timer stops timing until both conditions meet the preset value, and the timing is continued.
When the distance between the user and the far infrared light source is too far, or the eyes of the user look at other places in the eye-protection health-care time meter, the irradiation time of the far infrared light beam is shortened, the far infrared radiation flux entering eyes of a human body is reduced, and the eye-protection effect is reduced. Through face identification system and ranging system's setting, guaranteed that far infrared light source just opens when the user sees far infrared light source and with its distance in the default, so the user can receive sufficient radiant flux when doing far infrared phototherapy eyes, and then guaranteed eye protection effect.
Further, the detection ends of the face recognition system and the ranging system are arranged on the lower support rod, and the lamp housing shields the detection ends when the far infrared light source is closed.
Because the far infrared light source is arranged on the lower supporting rod, the detection ends of the face recognition system and the distance measurement system are arranged on the lower supporting rod, so that the measurement and judgment of whether the eyes of a user look at the far infrared light source or not and the distance between eyes and the far infrared light source are facilitated; when the far infrared light source is closed, the lamp housing shields the detection end and can protect the detection end, so that the maintenance cost is reduced, and the dustproof effect is achieved.
Further, the wavelength of the far infrared light source is 650-750 nm, and the irradiation illuminance of the far infrared light source is 2.0uw/cm 2-2.4 uw/cm2.
Further, the illumination light source is a full spectrum light source, the illumination surface of the illumination light source is circular, the edge of the illumination surface close to the use side is higher than or flush with the edge far from the use side, and the included angle between the illumination surface and the horizontal plane is 0-30 degrees.
The illumination light source is a full spectrum light source, so that the full spectrum light source is close to natural light, a natural and real lamplight environment can be created for a user during illumination, meanwhile, the damage of blue light to eyes can be reduced by lamplight emitted by the full spectrum light source, and strobe is avoided. So that the fatigue of eyes is reduced, and eyes can be protected when a user uses the desk lamp to illuminate.
When the edge of the illumination light source close to the use side is higher than the edge far from the use side, the irradiation surface faces the use side; at this time, the proper included angle between the irradiation surface and the horizontal plane can avoid the problem that the illumination light source directly irradiates into eyes of a user to cause light dazzling. When the two edges are level, the illumination surface is in a horizontal state, and the illumination light source directly irradiates against the desk lamp placing platform. At this time, the angle between the irradiated surface and the horizontal plane is 0 °.
Another object of the present invention is to provide a control method of a myopia prevention and control eye protection desk lamp, based on the desk lamp described in the claims, the control method comprising the following steps:
s1, starting an illumination light source, and accumulating the duration of the illumination light source to be T1; when T1 reaches a preset value, giving an alarm;
s2, starting a far infrared light source within a preset warning time T2, immediately ending the warning, and re-clearing 0 by T1, if the far infrared light source is not started within the T2, ending the warning after the T2 is ended, and re-clearing 0 by T1;
s3, starting a far infrared light source, stopping an illumination light source, detecting a protection countdown T4, and if the protection countdown T4 is not within the protection range of the protection countdown T4, starting countdown for a preset one-time health care time T3;
s4, detecting the distance and the face direction of the user and the far infrared light source, continuously counting down T3 when the distance and the face direction of the user meet preset conditions, stopping counting down T3 when the distance and/or the face direction of the user do not meet preset conditions, and giving out a warning;
and S5, after the countdown of the T3 is finished, the far infrared light automatically stops, and the protection countdown T4 is entered.
When the duration T1 of the illumination light source reaches a preset value, an alarm is sent to remind a user to carry out eye phototherapy, so that periodic rest and eye protection are realized, the problem that the user forgets to rest to cause excessive eye use is avoided, the alarm can last for a short period of time T2, and the user is prevented from missing the alarm. The health care time T3 is the duration of the turn-on of the far infrared light source; the detection protection countdown T4 is the shortest time interval for starting the far infrared light source twice, is less than the duration of T1, and can be successfully started only when the far infrared light source is started and the time from the last phototherapy is more than T4, so that the eye phototherapy is prevented from being excessively damaged. When the distance between the user and the far infrared light source and the face orientation meet preset conditions, the T3 starts counting down, and the phototherapy effectiveness of the far infrared light source is ensured.
