技术领域Technical Field
本申请涉及了台灯照明领域，具体涉及了一种全色仿生护眼台灯及其照明方法。The present application relates to the field of desk lamp lighting, and in particular to a full-color bionic eye-protection desk lamp and a lighting method thereof.
背景技术Background technique
台灯作为一种独立光源照明电器，已经被广泛的用于人们的生活中。台灯一般指放在桌子上用的有底座的电灯，主要用于阅读、学习、工作等目的的照明。As an independent light source lighting appliance, table lamps have been widely used in people's lives. Table lamps generally refer to electric lamps with bases placed on tables, mainly used for lighting purposes such as reading, studying, and working.
人眼是在自然光照环境下形成和进化的，视觉对自然光的适应性是无可取代的。眼睛看纯蓝光时，眼睛不自然的会睁大点看，使蓝光的成像落在视网膜上；眼睛看纯红光时，眼睛不自然的会眯一点看，使红光的成像落在视网膜上。普通的人工照明光谱中存在红光光谱缺少，且蓝光光谱量过高的问题，长时间的用眼后，不仅能伤害到视网膜黄斑区，还会很容易引起“眼疲劳”，形成近视。强化照明光谱中红光光谱以及减弱蓝光光谱对降低眼睛疲劳和预防近视具有十分重要的意义。The human eye was formed and evolved under natural lighting conditions, and the adaptability of vision to natural light is irreplaceable. When the eyes look at pure blue light, the eyes will open wider unnaturally, so that the image of the blue light falls on the retina; when the eyes look at pure red light, the eyes will squint unnaturally, so that the image of the red light falls on the retina. There is a lack of red light spectrum and too much blue light spectrum in the ordinary artificial lighting spectrum. After long-term use of the eyes, it can not only damage the retinal macular area, but also easily cause "eye fatigue" and form myopia. Strengthening the red light spectrum in the lighting spectrum and weakening the blue light spectrum are of great significance in reducing eye fatigue and preventing myopia.
再有，当人眼在看书或写字时，往往会“聚精会神”或“目不转睛”的盯着被视物体，这样，久视后，眼睛长时间固焦，眼睛易疲劳，尤其是在发光光色中，缺失红光光谱时，眼睛久视物体，容易导致眼轴变长，产生近视。Furthermore, when people are reading or writing, they tend to "concentrate" or "stare intently" at the object being viewed. In this way, after looking for a long time, the eyes will be focused for a long time and the eyes will easily become tired, especially when the red light spectrum is missing in the luminous light color. Looking at the object for a long time can easily lead to the elongation of the eye axis and cause myopia.
因此，研发出一种结构简单，便于收纳且能够很好的实现符合视觉习性可调眼轴方法来实现保护眼睛、减缓眼睛疲劳、减轻或预防近视的台灯及其照明方法具有十分重要的意义。Therefore, it is of great significance to develop a desk lamp and a lighting method thereof which has a simple structure, is easy to store and can well realize an adjustable eye axis method in accordance with visual habits to protect the eyes, relieve eye fatigue, and reduce or prevent myopia.
技术问题technical problem

The present application provides a full-color bionic eye protection desk lamp and a lighting method thereof. The desk lamp provided by the present application has a simple structure and is easy to store. At the same time, the lighting method of the desk lamp provides independent dimming bionic visual control, which turns static light into dynamic light. The spectrum remains unchanged when the brightness changes and does not cause visual adaptation, so that the eyes blink and the eyeballs focus and reset autonomously, thereby realizing active adjustment of the eye axis in accordance with visual habits, while achieving the effect of protecting the eyes, reducing eye fatigue, and alleviating or preventing myopia.

步骤3、重复所述步骤1～所述步骤2的步骤，进行循环照明；其中所述步骤1中，照明时间合计量为15s～20s，所述步骤2中，照明时间合计量为15s～20s。整个照明过程中，通过调节照明色温值变化和亮度变化的配合，在色温渐变过程中，在特定时间内完成高亮度至低亮度的切换和低亮度到高亮度的切换，把静态光变为动态光，同时能避免视觉的自适应，通过针对性调整了照明光源和照明过程中的光源亮度和色温的同时变化，在优异的光源照明下，仿生态变化亮度，实现“重置”人眼的主动调节眼轴功能，让人不自觉的眨眼，且主动调节眼轴符合视觉习性，从而可达到保护眼睛、减缓眼睛疲劳、减轻或预防近视的效果。Step 3, repeating the steps of step 1 to step 2 to perform cyclic lighting; wherein in step 1, the total lighting time is 15s to 20s, and in step 2, the total lighting time is 15s to 20s. During the entire lighting process, by adjusting the coordination of lighting color temperature value change and brightness change, in the process of color temperature gradient change, the switching from high brightness to low brightness and from low brightness to high brightness is completed within a specific time, and static light is changed into dynamic light, while visual adaptation can be avoided. By specifically adjusting the lighting source and the simultaneous changes of the light source brightness and color temperature during the lighting process, under the lighting of excellent light sources, the brightness changes in an ecological way, and the active adjustment of the eye axis function of the human eye is achieved, which makes people blink unconsciously, and the active adjustment of the eye axis is in line with visual habits, thereby protecting the eyes, alleviating eye fatigue, and reducing or preventing myopia.
进一步的，所述步骤1中，照明光源从最高色温值渐变至最低色温值的时间为10s～13s。例如，10s；11s；12s；13s。Furthermore, in step 1, the time for the illumination light source to gradually change from the highest color temperature value to the lowest color temperature value is 10s to 13s, for example, 10s; 11s; 12s; 13s.
进一步的，所述步骤2中，照明光源从最低色温值渐变至最高色温值的时间为10s～13s。例如，10s；11s；12s；13s。Furthermore, in step 2, the time for the illumination light source to gradually change from the lowest color temperature value to the highest color temperature value is 10s to 13s, for example, 10s; 11s; 12s; 13s.
进一步的，所述步骤1中，照明亮度从100％亮度值在0.8s～1.0s内，降至25％～45％的亮度值，保持照明3.5s～5s。研究发现，高亮度值降为低亮度值的时间，以及低亮度值的照明时间均为实现人不自觉眨眼，主动调节眼轴的关键性因素，并在低亮度值的合理选择范围的协同作用下，可有效提高用眼的舒适度，缓解眼疲劳，保护眼睛，实现减轻或预防近视的效果。其中，过快的将高亮度值调至低亮度值，会对人眼产生自适应效果，人眼来不及调节眼轴，因为人视觉在明暗光线变化或切换下，视觉的自适应时间长度或视觉对外界感观的自适应条件反射，会导致眼轴不会产生变化，无法实现主动调节眼轴，难以实现缓解眼疲劳，并实现减轻或预防近视的效果。但是过慢的将高亮度值调至低亮度值，也无法起到静态光到动态光的转变的效果，缓解眼疲劳的效果会明显变差，无法实现良好的护眼功效。所述步骤1中，高亮度值降为低亮度值的时间可以是0.8s；0.9s；1s。所述步骤1中，低亮度值的照明时间，可以是3.5s，4s，4.5s，5s。Furthermore, in step 1, the lighting brightness is reduced from 100% brightness value to 25% to 45% brightness value within 0.8s to 1.0s, and the lighting is maintained for 3.5s to 5s. Studies have found that the time when the high brightness value is reduced to the low brightness value, and the lighting time of the low brightness value are both key factors for realizing people's unconscious blinking and actively adjusting the eye axis, and under the synergistic effect of the reasonable selection range of the low brightness value, it can effectively improve the comfort of the eyes, relieve eye fatigue, protect the eyes, and achieve the effect of reducing or preventing myopia. Among them, adjusting the high brightness value to the low brightness value too quickly will produce an adaptive effect on the human eye, and the human eye will not have time to adjust the eye axis, because the adaptive time length of the vision or the adaptive conditioned reflex of the vision to the external sense under the change or switching of light and dark light will cause the eye axis to not change, and it is impossible to achieve active adjustment of the eye axis, and it is difficult to achieve the effect of relieving eye fatigue and reducing or preventing myopia. However, if the high brightness value is adjusted to the low brightness value too slowly, the effect of converting from static light to dynamic light cannot be achieved, the effect of relieving eye fatigue will be significantly worse, and good eye protection effect cannot be achieved. In step 1, the time for the high brightness value to drop to the low brightness value can be 0.8s; 0.9s; 1s. In step 1, the lighting time of the low brightness value can be 3.5s, 4s, 4.5s, 5s.
进一步的，所述步骤2中，照明亮度从100％亮度值在0.8s～1.0s内，降至25％～45％的亮度值，保持照明3.5s～5s。研究发现，高亮度值降为低亮度值的时间，以及低亮度值的照明时间均为实现人不自觉眨眼，主动调节眼轴的关键性因素，并在低亮度值的合理选择范围的协同作用下，可有效提高用眼的舒适度，缓解眼疲劳，保护眼睛，实现减轻或预防近视的效果。其中，过快的将高亮度值调至低亮度值，会对人眼产生自适应效果，人眼来不及调节眼轴，因为人视觉在明暗光线变化或切换下，视觉的自适应时间长度或视觉对外界感观的自适应条件反射，会导致眼轴不会产生变化，无法实现主动调节眼轴，难以实现缓解眼疲劳，并实现减轻或预防近视的效果。但是过慢的将高亮度值调至低亮度值，也无法起到静态光到动态光的转变的效果，缓解眼疲劳的效果会明显变差，无法实现良好的护眼功效。所述步骤2中，高亮度值降为低亮度值的时间可以是0.8s；0.9s；1s。所述步骤2中，低亮度值的照明时间，可以是3.5s，4s，4.5s，5s。Further, in step 2, the lighting brightness is reduced from 100% brightness value to 25% to 45% brightness value within 0.8s to 1.0s, and the lighting is maintained for 3.5s to 5s. Studies have found that the time when the high brightness value is reduced to the low brightness value, and the lighting time of the low brightness value are both key factors for realizing people's unconscious blinking and actively adjusting the eye axis, and under the synergistic effect of the reasonable selection range of the low brightness value, it can effectively improve the comfort of the eyes, relieve eye fatigue, protect the eyes, and achieve the effect of reducing or preventing myopia. Among them, adjusting the high brightness value to the low brightness value too quickly will produce an adaptive effect on the human eye, and the human eye will not have time to adjust the eye axis, because the adaptive time length of the vision or the adaptive conditioned reflex of the vision to the external sense under the change or switching of light and dark light will cause the eye axis to not change, and it is impossible to achieve active adjustment of the eye axis, and it is difficult to achieve the effect of relieving eye fatigue and reducing or preventing myopia. However, if the high brightness value is adjusted to the low brightness value too slowly, the effect of converting static light to dynamic light cannot be achieved, the effect of relieving eye fatigue will be significantly worse, and good eye protection effect cannot be achieved. In step 2, the time for the high brightness value to drop to the low brightness value can be 0.8s; 0.9s; 1s. In step 2, the lighting time of the low brightness value can be 3.5s, 4s, 4.5s, 5s.
进一步的，所述步骤1中，亮度值在0.8s～1.0s内，上升至100％亮度值。研究发现，低亮度值降为高亮度值的时间，以及高亮度值的照明时间均为实现人不自觉眨眼，主动调节眼轴的关键性因素，是可有效提高用眼的舒适度，缓解眼疲劳，保护眼睛，实现减轻或预防近视的必要条件。其中，过快的将低亮度值调至高亮度值，会对人眼产生自适应效果，人眼来不及调节眼轴，因为人视觉在明暗光线变化或切换下，视觉的自适应时间长度或视觉对外界感观的自适应条件反射，会导致眼轴不会产生变化，无法实现主动调节眼轴，难 以实现缓解眼疲劳，并实现减轻或预防近视的效果。但是过慢的将低亮度值调至高亮度值，也无法起到静态光到动态光的转变的效果，缓解眼疲劳的效果会明显变差，无法实现良好的护眼功效。例如，所述步骤1，低亮度值升为高亮度值的时间可以是0.8s；0.9s；1s。Furthermore, in step 1, the brightness value rises to 100% brightness value within 0.8s to 1.0s. Studies have found that the time for a low brightness value to drop to a high brightness value, and the lighting time of a high brightness value are key factors in achieving unconscious blinking and active adjustment of the eye axis, and are necessary conditions for effectively improving eye comfort, relieving eye fatigue, protecting the eyes, and reducing or preventing myopia. Among them, adjusting the low brightness value to a high brightness value too quickly will have an adaptive effect on the human eye, and the human eye will not have time to adjust the eye axis. Because of the changes or switching of light and dark, the adaptive time length of vision or the adaptive conditioned reflex of vision to the external sense will cause the eye axis to not change, and active adjustment of the eye axis cannot be achieved, which makes it difficult to adjust the eye axis. In order to relieve eye fatigue and reduce or prevent myopia. However, if the low brightness value is adjusted to the high brightness value too slowly, it will not achieve the effect of converting static light to dynamic light, and the effect of relieving eye fatigue will be significantly worse, and good eye protection effect cannot be achieved. For example, in step 1, the time from the low brightness value to the high brightness value can be 0.8s; 0.9s; 1s.
进一步的，所述步骤2中，亮度值在0.8s～1.0s内，上升至100％亮度值。研究发现，低亮度值降为高亮度值的时间，以及高亮度值的照明时间均为实现人不自觉眨眼，主动调节眼轴的关键性因素，是可有效提高用眼的舒适度，缓解眼疲劳，保护眼睛，实现减轻或预防近视的必要条件。其中，过快的将低亮度值调至高亮度值，会对人眼产生自适应效果，人眼来不及调节眼轴，因为人视觉在明暗光线变化或切换下，视觉的自适应时间长度或视觉对外界感观的自适应条件反射，会导致眼轴不会产生变化，无法实现主动调节眼轴，难以实现缓解眼疲劳，并实现减轻或预防近视的效果。但是过慢的将低亮度值调至高亮度值，也无法起到静态光到动态光的转变的效果，缓解眼疲劳的效果会明显变差，无法实现良好的护眼功效。例如，所述步骤2，低亮度值升为高亮度值的时间可以是0.8s；0.9s；1s。Further, in step 2, the brightness value rises to 100% brightness value within 0.8s to 1.0s. Studies have found that the time from the low brightness value to the high brightness value and the lighting time of the high brightness value are key factors for realizing unconscious blinking and actively adjusting the eye axis, which can effectively improve the comfort of eye use, relieve eye fatigue, protect the eyes, and achieve the necessary conditions for reducing or preventing myopia. Among them, adjusting the low brightness value to the high brightness value too quickly will produce an adaptive effect on the human eye, and the human eye will not have time to adjust the eye axis, because the adaptive time length of the vision or the adaptive conditioned reflex of the vision to the external sense under the change or switching of light and dark light will cause the eye axis to not change, and it is impossible to actively adjust the eye axis, and it is difficult to achieve the effect of relieving eye fatigue and reducing or preventing myopia. However, adjusting the low brightness value to the high brightness value too slowly will not have the effect of converting static light to dynamic light, and the effect of relieving eye fatigue will be significantly worse, and good eye protection effect cannot be achieved. For example, in step 2, the time for the low brightness value to increase to the high brightness value may be 0.8s; 0.9s; or 1s.
进一步的，所述步骤1中，整个亮度值变化的时间合计量为16s～20s，所述步骤2中，整个亮度值变化的时间合计量为为16s～20s。研究发现，即使满足亮度转换过程中的切换时间，整个亮度调节过程中的总时间也是影响护眼效果的关键性因素，整个亮度调节过程中的时间不易过长，也不易过短，否则会明显降低用眼舒适度，对近视的减轻或预防较差。例如，照明时间合计量为16s；17s；18s；19s；20s。Furthermore, in step 1, the total time of the entire brightness value change is 16s to 20s, and in step 2, the total time of the entire brightness value change is 16s to 20s. Studies have found that even if the switching time in the brightness conversion process is met, the total time of the entire brightness adjustment process is also a key factor affecting the eye protection effect. The time of the entire brightness adjustment process should not be too long or too short, otherwise it will significantly reduce the comfort of the eyes, and the reduction or prevention of myopia will be poor. For example, the total lighting time is 16s; 17s; 18s; 19s; 20s.
进一步的，100％的亮度值不低于600Lux，25％～45％的亮度值不大于400Lux。选择合适的亮度，可以增加人的舒适度，缓解眼部的疲劳。优选地，100％的亮度值不低于800Lux，25％～45％的亮度值不大于300Lux。更优选地，100％的亮度值不低于800Lux，25％～45％的亮度值为150～300Lux。Furthermore, the brightness value of 100% is not less than 600 Lux, and the brightness value of 25% to 45% is not greater than 400 Lux. Selecting the appropriate brightness can increase people's comfort and relieve eye fatigue. Preferably, the brightness value of 100% is not less than 800 Lux, and the brightness value of 25% to 45% is not greater than 300 Lux. More preferably, the brightness value of 100% is not less than 800 Lux, and the brightness value of 25% to 45% is 150 to 300 Lux.
进一步的，最高色温值≤高色温光源组的色温值，最低色温值≥低色温光源组的色温值。Furthermore, the highest color temperature value is ≤ the color temperature value of the high color temperature light source group, and the lowest color temperature value is ≥ the color temperature value of the low color temperature light source group.
进一步的，最高色温值与最低色温值的差值≤3000K。当最高色温值和最低色温值相差较大时，照明过程中，可有效保证人眼的舒适度，缓解眼部的疲劳，达到减轻或预防近视的效果。Furthermore, the difference between the highest color temperature value and the lowest color temperature value is ≤3000 K. When the highest color temperature value and the lowest color temperature value differ greatly, the comfort of human eyes can be effectively guaranteed during the lighting process, eye fatigue can be relieved, and the effect of reducing or preventing myopia can be achieved.

从表2的测试结果来看，实施例2-4采用本申请的技术方案，缓解眼疲劳性得分可达9.7分，中高度近视以及轻度近视眼睛的治疗有效率达到了100％，最高可降低200度，通过针对性调整了照明光源和照明过程中的光源亮度值变化方法，在优异的光源照明下，仿生态变化亮度，实现“重置”人眼的主动调节眼轴功能，让人不自觉的眨眼，且主动调节眼轴符合视觉习性，从而可达到保护眼睛、减缓眼睛疲劳以及减轻或预防近视的效果。对比例1-对比例2未采用本申请的全色仿生光源，缓解眼疲劳的效果明显降低，有部分眼睛还会产生度数升高的现象，无法实现良好的减轻或预防近视的效果。仅采用常规的照明光源和常规的照明方式，眼睛度数均会不同程度的升高，出现非近视眼睛转为近视眼的情况，技术效果差。From the test results of Table 2, Example 2-4 adopts the technical solution of the present application, and the score of relieving eye fatigue can reach 9.7 points. The treatment efficiency of moderate and high myopia and mild myopia eyes reaches 100%, and the maximum can be reduced by 200 degrees. By adjusting the illumination source and the method of changing the brightness value of the light source during the illumination process, the brightness is changed by mimicking ecology under the illumination of excellent light sources, and the active adjustment of the eye axis function of the human eye is realized to "reset" and make people blink unconsciously. The active adjustment of the eye axis conforms to the visual habits, so as to achieve the effect of protecting the eyes, relieving eye fatigue, and reducing or preventing myopia. Comparative Examples 1-Comparative Examples 2 do not adopt the full-color bionic light source of the present application, and the effect of relieving eye fatigue is significantly reduced. Some eyes will also produce the phenomenon of increased degree, and it is impossible to achieve a good effect of reducing or preventing myopia. Only conventional illumination sources and conventional lighting methods are used, and the degree of the eyes will increase to varying degrees, and non-myopic eyes will turn into myopic eyes, and the technical effect is poor.
