Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and more specifically, to a negative ion eye-protecting lamp that can inhibit myopia and relieve eye fatigue. Background Technology

[0002] Light is the only medium through which the eyes distinguish all things and perceive the world. For millions of years, humans have evolved into their current form under sunlight and in forests. With the development of cities, most people are now far removed from sunlight and forests, spending long periods of time indoors and relying on artificial light to distinguish things, resulting in increasingly serious vision problems such as myopia and dry eyes. Choosing suitable eye-protecting lamps can effectively reduce eye fatigue and improve visual comfort, thereby protecting visual health while meeting lighting needs.

[0003] Currently, eye-protection lamp technology is shifting from traditional blue LED technology to full-spectrum lighting technology, and is being combined with ion technology to create eye-protection lamps that combine negative ion technology with full-spectrum technology. There are multiple reasons behind this trend. The popularity of negative ion technology is mainly due to the negative ion generator producing negative ions, which increase blood oxygen concentration, eliminate free radicals in the body, and thus relieve fatigue.

[0004] However, despite the undeniable potential of negative ion technology in improving indoor environmental quality and promoting human health, we still face a series of challenges and considerations when applying it to the specific area of ​​relieving eye fatigue.

[0005] Firstly, regarding the effect of negative ion technology on relieving eye fatigue, although some studies have indicated that negative oxygen ions may have a certain relaxing effect on the human body, including relieving tension and fatigue, the mechanism by which they affect the local microcirculation of the eyes and the activity of retinal cells has not yet been fully scientifically verified.

[0006] Secondly, regarding the design and optimization of negative ion generators, the high-voltage generator, as the core component for generating negative ions, directly affects the generation efficiency and concentration of negative ions. Theoretically, increasing the number of high-voltage generators or improving their power can indeed increase the generation speed and concentration of negative ions, but this also leads to increased energy consumption, larger equipment size, and higher costs. Especially when considering integrating negative ion technology into everyday consumer products such as eye-protection lamps, how to control costs while ensuring effectiveness has become a pressing technical challenge.

[0007] In view of this, we propose a negative oxygen ion eye-protecting lamp that can inhibit myopia and relieve eye fatigue. Summary of the Invention

[0008] The purpose of this invention is to provide a negative ion eye-protecting lamp that can inhibit myopia and relieve eye fatigue, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A negative ion eye-protecting lamp that can inhibit myopia and relieve eye fatigue includes an eye-protecting lamp body, a lamp post, and a negative ion generator. The eye-protecting lamp body is used to emit full-spectrum light; the negative ion generator is installed at the connection between the eye-protecting lamp body and the lamp post, and the concentration of negative ions produced by the negative ion generator is 5000-50000 ions / cm³. 3 .

[0011] As a further aspect of the present invention: the negative oxygen ion generator includes a shell, and a power supply and several high-voltage generators are provided inside the shell. The power supply is used to supply power to the high-voltage generators, and the high-voltage generators are used to generate a high-voltage electric field.

[0012] As a further aspect of the present invention: the output end of the high voltage generator is provided with a discharge electrode for ionizing air molecules to generate negative oxygen ions, and the outer casing is provided with a plurality of release ports for discharging negative oxygen ions on the side near the discharge electrode.

[0013] As a further aspect of the present invention: a main through hole is provided at the center of the release port, and a plurality of auxiliary through holes are arranged in a ring around the main through hole with the main through hole as the center. The diameter of the main through hole is 3 to 5 cm, and the diameter of the auxiliary through holes is 1 to 2 cm.

[0014] As a further aspect of the present invention, the output voltage of the high voltage generator is -3000 to -3500V.

[0015] As a further aspect of the present invention: a control device for controlling the start-up of the eye-protection lamp body and the negative ion generator is provided on one side of the lamp post, and a base is fixed at the end of the lamp post away from the negative ion generator.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This negative ion eye-protecting lamp, which can inhibit myopia and relieve eye fatigue, incorporates a negative ion generator at the connection between the lamp body and the lamp post. The generator produces negative ions at a concentration of 5000–50000 ions / cm³. 3 The negative oxygen ions can stimulate the body to secrete more dopamine, increase blood flow density in the fundus and the activity of retinal cells, increase the thickness of the choroid, and thus improve visual comfort, thereby inhibiting myopia and relieving eye fatigue.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1 As shown, this embodiment provides a negative ion eye-protection lamp that can suppress myopia and relieve eye fatigue. It includes an eye-protection lamp body 10, a lamp post 20, and a negative ion generator 30. Considering that full-spectrum light is more effective in protecting the eyes than light excited by blue light chips, the eye-protection lamp body 10 is used to emit full-spectrum light. For ease of circuit control and aesthetic appeal, the negative ion generator 30 is installed at the connection between the eye-protection lamp body 10 and the lamp post 20. A control device 40 is provided on one side of the lamp post 20. The control device 40 controls the eye-protection lamp body 10 and the negative ion generator 30, and adjusts the rate at which the negative ion generator 30 generates negative ions and the brightness of the eye-protection lamp body 10. A base is fixed to the end of the lamp post 20 away from the negative ion generator 30. The concentration of negative ions produced by the negative ion generator 30 is 5000–50000 ions / cm³. 3 .

[0025] like Figure 2 As shown, the negative ion generator 30 is further disclosed: the negative ion generator 30 includes a housing 31, and a power supply 32 and several high-voltage generators 33 are provided inside the housing 31. The power supply 32 is connected to the input terminal of the high-voltage generators 33 and is used to supply power to the high-voltage generators 33. The high-voltage generators 33 convert low-voltage DC power into high-voltage AC power, thereby generating a high-voltage electric field for subsequent components to release negative ions.

[0026] The output end of the high voltage generator 33 is provided with a discharge electrode 34. In this embodiment, the discharge electrode 34 is a metal needle made of metal materials such as tungsten and copper. The high voltage generator 33 conducts a high voltage electric field to generate a large electric field concentration, thereby accelerating the gathering of free electrons in the air towards the metal needle and ionizing the air molecules to form negative oxygen ions with negative charges.

[0027] To facilitate the release of negative oxygen ions, a release port 35 is provided on the side of the outer shell 31 near the discharge electrode 34.

[0028] To enhance the diffusion effect of negative oxygen ions, a main through-hole is located at the center of the release port 35. Surrounding the main through-hole are several auxiliary through-holes arranged in a ring around it. The main through-hole has a diameter of 3-5 cm, and the auxiliary through-holes have a diameter of 1-2 cm. The main through-hole allows free airflow, reducing air resistance and enabling negative ions to be released more smoothly into the air. Simultaneously, the larger through-hole increases the release area of ​​negative ions, improving release efficiency; while the auxiliary through-holes assist in diffusion. These smaller through-holes allow negative ions to form a wider distribution range during release, preventing excessive concentration in localized areas and thus improving the uniformity of negative ions in the air.

[0029] It should be further noted that the output voltage of the high voltage generator 33 is -3000 to -3500V.

[0030] In the above embodiments, an experiment was conducted on the negative ion eye-protecting lamp that can inhibit myopia and relieve eye fatigue at a light source color temperature of 3850K. The experimental procedure is as follows:

[0031] Eighty people of the same age group were randomly selected and randomly assigned to four groups (A, B, C, and D), with 20 people in each group. The average illuminance was 500 Lux, and the concentration of negative oxygen ions in the air was less than 100 ions / cm³. 3 In the test environment, all four groups used this eye-protection lamp, which can inhibit myopia and relieve eye fatigue. The lamp was placed 1 meter away from the test subjects, and the concentration of the negative ion emitter was adjusted. Group A used this eye-protection lamp with a negative ion concentration of 0; Group B used a lamp with a negative ion concentration of 1000-2000 ions / cm³. 3 This eye-protection lamp; Group C uses a negative oxygen ion concentration of 5000-50000 ions / cm³. ω This eye-protection lamp; Group D uses negative oxygen ion concentration of 50,000-100,000 ions / cm³. ω This eye-protecting lamp.

[0032] Test process:

[0033] S1. Close your eyes and rest for 20 minutes;

[0034] S2, Basic Eye Health Indicators Test;

[0035] S3. Simulate the product's usage environment and tasks;

[0036] S4. Eye health index test after experience.

[0037] The task in step S3 is as follows: Use the WST-168CF air negative ion detector to test the indoor environment. When the negative oxygen ion concentration required for the experiment is reached, the personnel enter the laboratory to perform a 45-minute visual task. The task content is in line with the cultural ability and work habits of the test subjects, ensuring that the workload of each test subject remains relatively constant during the test, with no significant differences.

[0038] The eye health indicators tested in steps S2 and S4 include: fundus blood flow density, choroidal thickness, and dopamine concentration.

[0039] The change in fundus blood flow density was measured using OCTA before and after the visual task, ΔFBD = FBD. 后 -FBD 前 ΔFBD represents the change in fundus blood flow density; FBD 后 The fundus blood flow density value after visual tasks; FBD 前 The fundus blood flow density value before visual tasks;

[0040] The change in choroid thickness was measured using an optical interferometry (OCT) scanner.

[0041] The steps for testing dopamine concentration are as follows:

[0042] a) A one-step sandwich enzyme-linked immunosorbent assay (ELISA) with double antibodies was used. The sample, standard, and HRP-labeled detection antibody were added sequentially to the microwells pre-coated with dopamine (DA) capture antibody. After incubation and thorough washing, the sample was developed with the substrate TMB. TMB was converted to blue under the catalysis of peroxidase, and then to yellow under the action of acid. The intensity of the color was positively correlated with the human DA in the sample. The absorbance (OD value) was measured at a wavelength of 450 nm using an ELISA reader, and the sample concentration was calculated.

[0043] b) Collect the retinal pigment epithelial cell culture medium, centrifuge at 1000×g for 20 minutes, and collect the supernatant;

[0044] c) Remove the kit 1 hour in advance and allow it to equilibrate to room temperature. Remove the required strips and set up standard and sample wells. Add 50 μL of different concentrations of standard to each standard well. The standard concentrations are: 120 nmol / L, 60 nmol / L, 30 nmol / L, 15 nmol / L, 7.5 nmol / L, and 3.75 nmol / L, respectively. Add 50 μL of the sample to be tested to each sample well; do not add any sample to the blank wells.

[0045] d) Except for the blank wells, add 100 μL of horseradish peroxidase (HRP) labeled detection antibody to each of the standard and sample wells, seal the reaction wells with sealing film, and incubate at 37°C for 60 min.

[0046] e) Discard the liquid, pat dry on absorbent paper, fill each well with washing liquid, let stand for 1 minute, shake off the washing liquid, pat dry on absorbent paper, and repeat this washing process 5 times.

[0047] f) Add 50 μL each of the substrate TMB-tetramethylbenzidine (3,3',5,5'-Tetramethylbenzidine) and H2O2 solution to each well, and incubate at 37°C in the dark for 15 min;

[0048] g) Add 50 μL of HCl stop solution to each well. Within 15 min, measure the OD value of each well at a wavelength of 450 nm using an ELISA reader.

[0049] h) Plot a standard curve in Excel with the OD value of the measured standard on the x-axis and the concentration value of the standard on the y-axis, and obtain a linear regression equation. Substitute the OD value of the sample into the equation to calculate the concentration of the sample.

[0050] The data for each experimental group are shown in Table 1:

[0051] Table 1

[0052]

[0053]

[0054]

[0055]

[0056] The data from each experimental group in Table 1 were statistically analyzed and averaged to obtain the range of variation and the mean variation, as shown in Table 2.

[0057] Table 2

[0058]

[0059] Table 2 shows that the experimental variable was the concentration of negative oxygen ions. After 45 minutes of product experience, the subjects' fundus blood flow density, choroidal thickness, and dopamine concentration all showed some improvement. The experimental results indicate that the concentration of negative oxygen ions in group C was between 5000 and 50000 ions / cm³. 3 The improvement values ​​of the above three indicators were all higher than those of Experiment A (negative oxygen ion concentration of 0) and Experiment B (negative oxygen ion concentration of 1000-2000 ions / cm³). 3 The concentration should be high, exceeding 50,000 negative oxygen ions / cm³. 3 At that time (i.e., experimental group D), the improvement in fundus blood flow density, choroidal thickness and dopamine concentration tended to level off;

[0060] In summary, negative oxygen ions can be used to increase the secretion of dopamine in the body, improve retinal blood flow density and retinal cell activity, increase choroidal thickness, and thus improve visual comfort, thereby inhibiting myopia and relieving eye strain. Furthermore, when the concentration of negative oxygen ions is between 5000 and 50000 ions / cm³, this effect is particularly pronounced. 3 At the same time, it can fully exert the beneficial effects of negative oxygen ions on organisms, and achieve a relatively ideal state in terms of cost control.
