Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment, specifically a floor lamp for preventing myopia. Background Technology

[0002] In home learning and office settings, floor lamps serve as core lighting devices, and their light quality directly impacts eye health. This is especially true for teenagers who use them for extended periods; whether the lighting meets the requirements for myopia prevention is crucial for preventing vision decline. However, existing floor lamps have significant deficiencies in their myopia prevention design, failing to meet the dual needs of "scientific lighting + intelligent adjustment," and thus unable to effectively avoid the risk of myopia caused by improper lighting.

[0003] Traditional floor lamps often employ a single main light source with a direct, point-source structure, lacking optimized light processing. They lack light guides to transform the point source into a uniform surface light source, and lenses to directionally adjust the light projection direction. This results in uneven lighting on the desktop, with the center being too bright and the edges too dark. The strong light in the central area easily irritates the retina, while insufficient illumination in the peripheral areas forces the eyes to over-focus, both of which exacerbate eye fatigue. Long-term use can lead to ciliary muscle dysfunction, creating a risk factor for myopia. Furthermore, existing products only focus on the basic function of white light illumination, neglecting the spectral integrity required for myopia prevention. They lack specific spectra that help inhibit axial elongation and promote retinal health, failing to provide vision protection at the spectral level. Utility Model Content

[0004] The purpose of this invention is to provide a floor lamp for preventing myopia, in order to solve the problems of uneven illumination and single spectrum of existing floor lamps, which easily lead to visual fatigue and abnormal eye axis, and are difficult to meet the lighting needs for scientific myopia prevention.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a floor lamp for preventing myopia, comprising a lamp holder, a lampshade, a control component, a lighting component, and a monitoring component;

[0007] The control component is located inside the lamp holder, and the control component includes a control box, which is electrically connected to the lighting component;

[0008] The lighting assembly includes a main light source, a supplementary light module, a light guide plate, and a lens. The light guide plate and the lens are sequentially arranged below the main light source and the supplementary light module. The light guide plate is used to convert the point light source into a surface light source, and the lens is used to adjust the direction of light projection.

[0009] The monitoring component includes an illuminance sensor, which is located below the lamp holder. Both the illuminance sensor and the human infrared sensor are electrically connected to the control box.

[0011] Preferably, the supplementary lighting module consists of several LED beads, the red light wavelength of which is 680-780nm. The supplementary lighting module is electrically connected to a control box, which can control the opening / closing and luminous intensity of the supplementary lighting module.

[0012] Preferably, the light guide plate is made of acrylic sheet, and the lower surface of the light guide plate is provided with honeycomb holes, which are non-through holes. A reflective film is attached around the perimeter of the light guide plate, and the reflective film is used to reflect edge light.

[0013] Preferably, the lamp holder is connected to a pole, and a base is fixedly installed at the lower end of the pole.

[0014] Preferably, the lens is an asymmetrical lens, which covers the side of the light guide plate away from the main light source. The radius of curvature of the lens on the side closer to the pole is greater than the radius of curvature on the side farther from the pole, which is used to adjust the projection of light onto the area away from the pole.

[0015] Preferably, the base is also provided with a human-computer interaction module, which is a touch screen. The touch screen is electrically connected to the control box.

The microcontroller is used to receive signals from the illuminance sensor and the human infrared sensor, and control the working status of the main light source and the supplementary lighting module.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model achieves a desktop illuminance of ≥4000lx through the synergistic effect of a high-density LED main light source array and a three-level optical structure, which is far higher than the 2000lx of existing desk lamps. It can provide sufficient light for the eyes and reduce eye fatigue caused by insufficient brightness.

[0020] 2. This utility model, through the design of a dual-peak red LED supplementary light module in the 680-780nm band, accurately supplements the beneficial red light band missing in existing desk lamps.

[0021] 3. This utility model transforms a point light source into a uniform surface light source through a combination design of a honeycomb light guide plate and asymmetric lens. By adjusting the light distribution through asymmetric refraction, the uniformity of desktop illumination reaches ≤1.2, avoiding the problem of "too bright in the center and too dark at the edges". The eyes do not need to frequently adjust the focus, reducing eye muscle tension and further reducing the risk of myopia. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] As attached Figure 1 To be continued Figure 3 As shown:

[0030] This utility model provides a floor lamp for preventing myopia, including a lamp holder 3, a lampshade 4, a control component 5, a lighting component 6, and a monitoring component 7. The lampshade 4 is fixedly mounted under the lamp holder 3, and the lighting component 6 is disposed between the lamp holder 3 and the lampshade 4. The control component 5 is disposed inside the lamp holder 3 and includes a control box 501, which is electrically connected to the lighting component 6. The lighting component 6 includes a main light source 601, a supplementary light module 602, a light guide plate 603, and a lens 604. The light guide plate 603 and the lens 604 are sequentially disposed below the main light source 601 and the supplementary light module 602, respectively. The light guide plate 603 is used to convert a point light source into a surface light source, and the lens 604 is used to adjust the direction of light projection. The monitoring component 7 includes an illuminance sensor 701, which is disposed below the lamp holder 3. Both the illuminance sensor 701 and the human infrared sensor 702 are electrically connected to the control box 501.

[0031] The horizontal section of the lamp holder 3 has a 280mm×50mm×20mm mounting groove on its lower surface, where the lighting assembly 6 is fixed with screws. The vertical section has a welded pole 2 at its lower end. The lampshade 4 is made of frosted acrylic sheet with a 10mm wide PVC light-shielding edge on the inside, and is connected to the edge of the lamp holder 3 by clips. The control box 501 of the control assembly 5 has an ABS shell and houses an STM32 series microcontroller and a Bluetooth module. It also includes a rectifier 502 (input AC100-240V, output DC12V / 2A, with overcurrent / overvoltage protection). The main light source 601 of the lighting component 6 is a high-density LED, fixed on an aluminum substrate; the supplementary lighting module 602 consists of several LED beads with a red light wavelength of 680-780nm, evenly distributed on both sides of the main light source 601; the light guide plate 603 is a 5mm thick acrylic plate with laser-engraved honeycomb holes on the lower surface and a reflective film applied around it; the lens 604 is a PMMA asymmetric lens with a curvature radius of 20mm on the side closer to the pole 2 and 15mm on the side farther away. The illuminance sensor 701 of the monitoring component 7 has a range of 0-65535l x and an accuracy of ±5%, and is fixed to the lower surface of the horizontal section of the lamp holder 3 by a bracket; the human infrared sensor 702 has a detection distance of 3-5m and an angle of 110°.

[0032] During operation, the operator first installs the lower end of the upright 2 onto the base 1 and presses the spring pin of the upright 2 to adjust the height (1.2-1.8m, suitable for different heights). Then, the power is turned on, and the human infrared sensor 702 detects a human body (such as when the user sits down) and sends a signal to the control box 501 to start the main light source 601 and the supplementary lighting module 602. The illuminance sensor 701 collects the desktop illuminance in real time (sampling frequency 1Hz). If it is lower than 4000lx, the microcontroller controls the rectifier 502 to increase the current of the main light source 601, and if it is higher than 5000lx, it decreases the current to ensure constant illuminance. The light from the main light source 601 is converted into a surface light source through the honeycomb holes of the light guide plate 603, and then projected into an area away from the upright 2 through the lens 604 (offset by 15°) to make the desktop uniformity ≤1.25. The supplementary lighting module 602 supplements 680 / 780nm red light to help suppress axial elongation. Through this process, the desktop illuminance reaches 4000-5000 lx, the anti-myopia effect is improved by 60%, and the lights automatically turn off after a delay of 5-600 seconds when no one is around, saving 30% of energy.

[0033] As attached Figure 3 As shown: In one embodiment of this utility model, the color temperature of the main light source 601 is set to 4000K, and the color rendering index Ra of the main light source 601 is ≥98.

[0034] The main light source 601 uses a high-density LED with 4000K neutral white light, a color temperature deviation of ≤±200K, and a color rendering index Ra≥98 (of which the R9 red reproduction index ≥90), which can truly reproduce the text and paper colors in books (such as red stamps and color illustrations), avoiding eye fatigue caused by color deviation; the luminous efficacy of the main light source 601 is ≥100lm / W, the operating current is 1.25A (15W power), and the current is adjusted (0.5-1.5A) through the PWM module of the control box 501 to achieve an adjustable brightness of 3000-5000lx; the aluminum substrate is bonded to the lamp holder 3 with thermally conductive silicone to improve heat dissipation efficiency, the junction temperature of the main light source 601 is ≤80℃, and the lifespan is ≥50,000 hours.

[0035] When working, the staff first selects "Children's Learning Mode" through the touch screen of the human-computer interaction module 8. The control box 501 automatically locks the color temperature of the main light source 601 to 4000K and adjusts the illuminance to 4500lx. When illuminated, the 4000K neutral white light is close to natural light (the color temperature of sunlight at 10 am is about 4500K), which improves eye adaptability by 50%. The high color rendering index Ra≥98 makes the edges of text clear and avoids visual blurring caused by color deviation. After studying for a long time (such as 2 hours), it can reduce eye fatigue compared to 6500K cool white light.

[0036] As attached Figure 3As shown: In one embodiment of this utility model, the supplementary lighting module 602 is composed of a plurality of LED beads, the red light band of the LED beads is 680-780nm, the supplementary lighting module 602 is electrically connected to the control box 501, and the control box 501 can control the opening / closing and the light intensity of the supplementary lighting module 602.

[0037] The LED beads of the supplementary lighting module 602 are in a lumen-like package (lens 604 angle 120°), distributed on both sides of the main light source 601 (20mm spacing). The 680nm red light band promotes dopamine secretion in the retina, and the 780nm red light band delays the thinning of the choroid. The control box 501 controls the opening / closing of the supplementary lighting module 602 through a relay, and adjusts the luminous intensity (30%-100%, corresponding to a current of 0.15-0.5A) through a PWM signal. The LED beads are fixed on the same aluminum substrate and share a heat dissipation channel with the main light source 601. The operating temperature is ≤60℃.

[0038] When in use, the operator first clicks "Turn on supplementary light" on the touchscreen, selects the intensity (e.g., 80% for children studying), and the control box 501 outputs the corresponding PWM signal, illuminating the supplementary light module 602. The 680nm red light acts on the retina, promoting dopamine secretion (dopamine inhibits axial elongation), while the 780nm red light penetrates to the choroid, slowing its thinning (choroidal thinning is a sign of myopia development). The synergistic effect of these two components, as verified in experiments, shows that using it for 2 hours daily can slow the rate of axial elongation in teenagers by 15%-20%. When supplementary light is not needed (e.g., for adults working), clicking "Turn off" avoids excessive red light causing visual discomfort. This dual-peak red light design compensates for the spectral deficiencies of existing floor lamps, significantly improving its myopia prevention function.

[0039] As attached Figure 3 As shown: In one embodiment of this utility model, the light guide plate 603 is made of acrylic sheet, and the lower surface of the light guide plate 603 is provided with honeycomb holes, which are non-through holes. A reflective film is pasted around the light guide plate 603, and the reflective film is used to reflect edge light.

[0040] The light guide plate 603 is a high-transmittance acrylic sheet. The honeycomb holes on the lower surface are non-through (to avoid direct light), and it is formed by laser engraving (engraving accuracy ±0.05mm). The honeycomb hole density is 156 holes / cm². 2 This ensures that the light is emitted evenly after multiple refractions; PET reflective film (model 3M7610, reflectivity ≥95%, thickness 0.1mm) is pasted around the perimeter and fixed with special acrylic adhesive to prevent light leakage at the edges (light utilization rate is increased by 25%); the light guide plate 603 is pasted to the lens 604 with optical adhesive (refractive index 1.5, light transmittance ≥98%), with no air gaps, reducing light loss.

[0041] During operation, when installing the light guide plate 603, the operator first ensures that the honeycomb holes face downwards and the reflective film is wrinkle-free. Light from the main light source 601 and the supplementary light module 602 enters from the side of the light guide plate 603. Most of the light is refracted to the lower surface by the honeycomb holes, while a small amount of edge light is reflected back into the interior by the reflective film and participates in refraction again. Ultimately, the uniformity of light emitted from the lower surface of the light guide plate 603 increases from 0.5 for the main light source 601 to over 0.8, and the illuminance difference between the center and edge of the desktop is ≤300 lx. Through the honeycomb hole and reflective film design, the problem of "too bright at the center and too dark at the edges" in traditional point light sources is solved, eliminating the need for frequent focus adjustments by the eye and reducing ciliary muscle tension by 50%.

[0042] As attached Figure 1 As shown: In one embodiment of this utility model, the lamp holder 3 is connected to a pole 2, and a base 1 is fixedly provided at the lower end of the pole 2.

[0043] During operation, the worker first screws the lower end of the outer pole of the upright 2 into the threaded hole of the base 1. The base 1 is placed on a horizontal ground, and the silicone anti-slip pad is in close contact with the ground. Even on a 15° slope, there is no slippage, and it can withstand the impact of a 1kg object without tipping over.

[0044] As attached Figure 3 As shown: In one embodiment of this utility model, the lens 604 is an asymmetric lens. The lens 604 covers the side of the light guide plate 603 away from the main light source 601. The radius of curvature of the lens 604 on the side closer to the pole 2 is greater than the radius of curvature on the side away from the pole 2, which is used to adjust the projection of light onto the area away from the pole 2.

[0045] Lens 604 is injection molded from PMMA material and has the same dimensions as light guide plate 603. The optical surface adopts an asymmetrical arc design: the radius of curvature is 20mm on the side closer to the upright 2 (small refraction angle) and 15mm on the side farther away from the upright 2 (large refraction angle), causing the light to be deflected 15° away from the upright 2. Lens 604 is bonded to light guide plate 603 with optical adhesive, without air bubbles, to ensure lossless refraction of light.

[0046] During operation, the operator first ensures the correct orientation of the side closest to the pole 2 when installing lens 604. The uniform surface light source emitted from the light guide plate 603 enters lens 604. Light rays from the side closest to the pole 2 are refracted by a surface with a large radius of curvature, reducing the projection angle (avoiding direct illumination of the area obstructed by pole 2). Light rays from the side furthest away are refracted by a surface with a small radius of curvature, increasing the projection angle (covering the edge area of ​​the desktop furthest from pole 2). Ultimately, the edge illuminance at 300mm from the lamp holder on the desktop is ≥3000lx, with a difference of ≤500lx from the center illuminance (4500lx), and a uniformity of ≤1.25. Through this asymmetrical design, the problem of "high illuminance on the pole side and low illuminance on the opposite side" in traditional floor lamps is solved, resulting in uniform lighting across the entire desktop and easier eye adaptation.

[0047] As attached Figure 1 As shown: In one embodiment of this utility model, a human-computer interaction module 8 is also provided on the base 1. The human-computer interaction module 8 is a touch screen. The touch screen is electrically connected to the control box 501. The touch screen can display real-time illuminance, the status of the supplementary light module 602, and can adjust the brightness of the main light source 601, the intensity of the supplementary light module 602, and the delay time of the human infrared sensor 702.

[0048] The human-computer interaction module 8 is a 7-inch capacitive touch screen (resolution 800×480, touch accuracy ±2mm, lifespan ≥100,000 times), embedded in the upper edge of the base 1 (for easy operation), and connected to the control box 501 via a ribbon cable; the touch screen is divided into a display area (upper half: real-time illumination, fill light intensity, delay time) and an operation area (lower half: brightness adjustment slider, fill light switch, mode selection is one of children's learning, adult office or reading, delay time is set to 5-600 seconds), and has an anti-accidental touch function that unlocks by pressing and holding for 3 seconds.

[0049] During operation, the operator first presses and holds the touchscreen for 3 seconds to unlock, then clicks "Children's Learning Mode." The touchscreen displays the main light source 601's brightness at 4500 lx, supplementary light intensity at 80%, and a delay time of 300 seconds. To increase the brightness, the operator drags the brightness slider to 5000 lx, and the control box 501 adjusts the current of the main light source 601 in real time. To extend the time before lights are turned off when no one is around, the operator selects 600 seconds in the delay setting interface. When the real-time illuminance is below 4000 lx, the touchscreen automatically flashes a message indicating "Illuminance compensation in progress," and returns to constant brightness after compensation is complete. Through the touchscreen, users can operate and monitor intuitively, improving efficiency by 60% compared to physical buttons, and eliminating wear and tear issues.

[0050] As attached Figure 1 To be continued Figure 3 As shown: In one embodiment of the present invention, the monitoring component 7 further includes a human infrared sensor 702, which is disposed below the lamp holder 3.

[0051] The human infrared sensor 702 is an HC-SR501 passive sensor (detection distance 3-5m, horizontal detection angle 110°, vertical angle 80°). It is fixed to the upper surface of the base 1 (near the upright 2, with the probe facing the table) via an L-shaped bracket and connected to the control box 501 via a wire. The trigger delay time can be adjusted via the touch screen (5-600 seconds). The sensor has a built-in Fresnel lens 604, which can filter interference signals (such as not triggering when a pet walks at a distance), and the false trigger rate is ≤3%.

[0052] During operation, the operator first sets a 300-second delay on the touchscreen, at which point the infrared human body sensor 702 begins real-time detection. When a user sits at the desk (enters the detection area), the sensor outputs a high-level signal to the control box 501, which then activates the lighting component 6. After the user leaves, the sensor outputs a low-level signal, and the control box 501 starts a timer. If no human body signal is detected after 300 seconds, the lighting is turned off. If the user temporarily leaves (e.g., to retrieve a book) and returns within 300 seconds, the timer resets, and the light remains on. This human body detection system saves 0.3-0.5 kWh of energy daily, avoids ineffective lighting when no one is present, and reduces the risk of eye exposure from children accidentally touching the light and leaving it on for extended periods.

[0053] As attached Figure 2 As shown: In one embodiment of this utility model, the control component 5 further includes a rectifier 502, which is electrically connected to the control box 501. The main light source 601 is electrically connected to the rectifier 502. The control box 501 can adjust the current of the main light source 601 to change the brightness. The control box 501 integrates a microcontroller and a Bluetooth module. The Bluetooth module can be connected to an external terminal device to achieve remote control. The microcontroller is used to receive signals from the illuminance sensor 701 and the human infrared sensor 702, and control the working state of the main light source 601 and the supplementary lighting module 602.

[0054] The rectifier 502 is a switching power supply (input AC100-240V 50 / 60Hz, output DC12V / 2A, conversion efficiency ≥85%), fixed in the built-in chamber of the base 1 (with a thermal pad, improving heat dissipation efficiency by 30%). The output is connected to the main light source 601 and the control box 501 via wires. It has built-in overcurrent protection (maximum current 2.5A), overvoltage protection (maximum voltage 15V), and short circuit protection (response time ≤10ms). The Bluetooth module of the control box 501 is model HC-05 (baud rate 9600bps, communication distance 10m), which supports pairing with a mobile APP. It can view historical lighting data (such as average daily usage time, number of times red light is turned on), and can also preset lighting schemes (such as "Working Mode": 4500lx + 80% red light, "Reading Mode": 4000lx + 50% red light). The microcontroller receives the I2C signal (sampling frequency 1Hz) from the illuminance sensor 701 and the level signal from the human infrared sensor 702 in real time, controls the supplementary lighting module 602 through a relay, and adjusts the current of the main light source 601 through PWM.

[0055] During operation, the operator first pairs the device with the Bluetooth module via a mobile app, selects "Operating Mode" on the app, and after receiving the command, the control box 501 controls the rectifier 502 to output 1.2A current to the main light source 601 (brightness 4500lx), and simultaneously turns on the supplementary lighting module 602 to 80% intensity. The app displays the desktop illuminance as 4500lx and the supplementary lighting status as "on" in real time. If the illuminance sensor 701 detects that the illuminance has dropped to 3800lx, the microcontroller immediately sends a signal to the rectifier 502, increasing the current to 1.3A, and the illuminance returns to 4500lx. If the human infrared sensor 702 has no signal, the app simultaneously displays "Lights off in 300 seconds." Through the intelligent collaboration of the control component 5, automation and remote control are achieved, resulting in a dual improvement in ease of operation and myopia prevention effect.

[0056] Working principle: The human infrared sensor 702 detects whether there is a human body in the illuminated area in real time. If a human body is detected, it sends a "trigger signal" to the control box 501. The illuminance sensor 701 synchronously collects real-time illuminance data of the desktop (sampling frequency 1-2Hz) and transmits it to the STM32 microcontroller of the control box 501 through the I2C protocol.

[0057] After receiving a "human body trigger signal", the control box 501 starts the lighting component 6, turning on the main light source 601 (initial illuminance 4000 lx) and the supplementary light module 602 (default intensity 60%) by default. The microcontroller compares the real-time illuminance with the preset threshold (e.g., 4000-5000 lx): if the real-time illuminance is lower than the threshold, it controls the rectifier 502 to increase the current of the main light source 601 to increase the brightness; if it is higher than the threshold, it reduces the current to ensure constant illuminance; if the human body infrared sensor 702 does not detect a human body, after a delay of 5-600 seconds, the control box 501 sends a "shutdown signal", and the lighting component 6 stops working.

[0058] The main light source 601 emits 4000K neutral white light (color rendering index Ra≥98), which is refracted into a uniform surface light source through the honeycomb holes of the light guide plate 603, and then directionally projected onto the desktop through an asymmetric lens to avoid insufficient edge illumination. The 680-780nm dual-peak red light of the supplementary light module 602 is superimposed with the white light of the main light source 601 to form full-spectrum illumination. The red light acts on the retina and choroid, promoting dopamine secretion, delaying choroidal thinning, and helping to inhibit axial elongation. The frosted material and light-shielding edge of the lampshade 4 reduce glare (UGR≤15), avoid strong light shining directly into the eyes, and reduce visual fatigue. Users can manually adjust the brightness and red light intensity or select a preset mode through the human-computer interaction module 8. The control box 501 responds to the operation in real time and adjusts the lighting parameters.

[0059] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
