Abstract: What is green lighting? There is no consensus at present. Therefore, this paper first defines the basic principle of green lighting as energy saving and meets the standard, and then on the basis of current lighting, proposes new technologies and new concepts such as illuminance compliance indicator, reference intelligent dimmer and its reading and writing area, aiming to form A new generation of lighting fixtures with the basic characteristics of "illumination level indication function + reference intelligent dimming function".
I. Problems raised <br> Electrical lighting For more than 100 years, the predecessors have made significant progress in research on the principle of illumination, luminescent materials, working frequency of light sources and their production processes, and have achieved today's brilliance. However, from the basic principles of green lighting, there are some common and neglected problems in current lighting fixtures. This project only explores four points, in order to form a new generation of lighting fixtures that meet the basic principles of green lighting - energy saving and compliance. Here is a brief analysis.
1 Light source aging problem. Is your learning environment illuminating? In fact, from the physical point of view, any (small-power cold/hot) light source produced by any material or any process during the lighting process will age for a long time and the brightness will decrease. Therefore, any luminaire, even if the illuminance is up to standard at the factory, it is impossible to reach the standard after using the illuminance for a long time, even though the lamp is not bad. This incurs the user to learn in an environment where the lights are not bad and the illumination is not up to standard. How can this not cause excessive fatigue of the visual nerves, low learning efficiency, deeper myopia or myopia! It can be seen that it is not enough to solve the problem of aging of the light source only from the aspects of light source materials and processes. To this end, we have also proposed the "learning environment illuminance compliance indicator + reference intelligent dimmer" from the perspective of luminaire circuit design: that is, during the illumination process, the illuminance compliance indicator always monitors and prompts the learning environment ( That is, the synthetic illuminance of the natural lighting environment + artificial lighting environment complies with the GB/CIE lighting standard, so that the luminaire in the illumination process, in the sense of illuminance compliance, always conforms to the basic principle of green lighting - energy saving and compliance, avoiding The illuminance does not meet the standard of myopia caused by myopia.
2 Read and write area issues. In the study table lamp involving thousands of households, the illuminance of the table lamp before the acceptance of this group of patents is small, about 35cm × 30cm, the middle of the workbook, the illuminance on the next book is not up to standard. To this end, the project defines the reading and writing area (RW) of the desk lamp as: a rectangular area about 50cm × 42cm in front of the desk lamp, in which the illuminance should meet the GB or CIE lighting standards, avoiding the illumination on the adjacent books. To achieve the myopia caused by this external cause.
3 lens aging problem. Why is the degree of wearing glasses getting deeper and deeper? I have consulted ophthalmologists many times. The answer is “more glasses.†In fact, from the physical point of view, any lens will naturally age after a long time. The longer the time, the more severe the aging, the lower the light transmittance, the effect The less luminous flux on the macula of the eyeball, the instinct of reading and writing is instinctive, and the degree of myopia is deepened. To this end, we proposed: "illuminance compliance indicator + reference intelligent proximity dimmer", designed to achieve the standard of illumination, when the head is less than the standard reading and writing distance of 30cm, the lamp source is intelligently brightened. In order to compensate for the reduction of the luminous flux acting on the macula of the eye caused by the natural aging of the lens, it is possible to avoid the myopia deepening caused by the aging of the lens and the reluctance to spend more glasses.
4 Matching problems between lighting and ambient brightness. Looking at our classrooms and offices, we can see that the environment near the windows is brighter and darker than the windows. Therefore, in order to meet the basic principle of green lighting - energy saving and compliance, the light near the window should be darker; away from the window, it should be brighter, that is, the lighting and ambient brightness should match each other. However, the reality is: the national, global classrooms, laboratories, reading rooms, reading halls, offices, shopping malls, streets, highways, the lighting and the brightness of the environment match? Or not matching or matching too bad! To this end, we propose a benchmark intelligent dimming method: that is, based on the GB/CIE lighting standard, if the ambient illuminance of the environment + light is greater than the GB/CIE lighting standard, the brightness of the light is reduced without power consumption so that the synthetic illuminance is consistent. GB/CIE lighting standard; on the contrary, the brightness of the light is increased without power consumption, so that the synthetic illumination meets the GB/CIE lighting standard, and the adjustment range is 2% to 100% of the lamp power, so that the illumination and the ambient brightness are illuminated. In the standard sense, it always matches, so the benchmark intelligent dimming technology is also called the benchmark intelligent lighting-environment brightness matching technology. The benchmark intelligent dimming method proposed by us basically adjusts the brightness of the lamp power by maximizing the ambient brightness around each lamp under the premise of lighting compliance, so it is about 15% to 30% more energy-efficient than similar lamps. The lamp life is extended by at least 30%, and the color rendering coefficient is higher, which is in line with the basic principle of green lighting.
In summary, based on the above four concepts and their corresponding three patents, a new generation of lighting fixtures with the basic features of illuminance compliance indication + reference intelligent dimming function can be formed, thereby overcoming the inability of current lighting fixtures to overcome. The above four common and neglected problems make it conform to the basic principles of green lighting and save energy and meet the standard while extending the life of the lamp.
Second, the performance of the prototype project Introduction <br> this project can be used for all standard and in need of green illumination lighting applications, such as shopping malls, offices, classrooms, laboratories, libraries, reading rooms, street lights, solar lights, and so on. The three performance prototypes we have made: the learning environment illuminance compliance indicator (black), the benchmark intelligent dimming learning desk lamp, and the benchmark intelligent proximity dimming learning desk lamp, just to verify the rationality of the above four concepts and their corresponding three The feasibility of the patent. The invention is used for studying table lamps, and aims to solve the myopia caused by the aging of the light source, the lamp is not bad, and the illumination is not up to standard, instead of saving energy, although it itself is energy-saving. For convenience, the learning environment illuminance indicator has been built into the new generation of lighting fixtures. Of course, it can also be produced independently to detect whether the illumination of the user's learning environment is up to standard. The brief introduction is as follows.
A, benchmark intelligent dimming learning desk lamp (blue)
1. Design purpose: To ensure that the learning environment meets the GB/CIE lighting standard and overcome the myopia caused by the illuminance caused by the aging of the light source.
2. Applicable people: children and adolescents.
3. There are two new functions: (that is, the function that the current learning desk lamp does not have)
(1) Illumination compliance indicator function learning environment illuminance compliance indicator, during the use of learning desk lamp, always monitor and prompt its reading and writing area RW: illuminance within 50cm × 42cm meets GB/CIE lighting standards, thus monitoring and Make sure the lighting is always up to standard in the sense.
(2) The reference intelligent dimming function has a learning desk lamp that learns the illumination illuminance compliance indication function. Although it can solve the old problem of myopia caused by the natural aging lamp of the light source and the illumination is not up to standard in the sense of monitoring and prompting, However, it will lead to the elimination or reuse of the lamp for illuminance. To this end, our original patented technology reference intelligent dimmer was enabled to form a learning desk lamp with "learning environment illumination level indication function + reference intelligent dimming function". It is worth noting that the traditional dimming technology has two characteristics: First, it feels the light and dimming of the environment. Obviously, this is contrary to the lighting industry standards. Secondly, the traditional dimming technology uses the voltage division method or the angle adjustment method (that is, controls the conduction angle of the triac) to dim, so it is impossible to make continuous dimming without power consumption, and at the same time, the light source must be lowered. The color rendering coefficient, deteriorating the quality of the light source. Our proposed benchmark intelligent dimming technology is a typical power-free, uninterrupted, dimming technology based on GB/CIE lighting standards. Therefore, as long as we adopt our patented technology and use a large number of lamps, such as 24 watts to 27 watts of H tubes, the standard intelligent dimming can be achieved simply by using GB or CIE lighting standards, thus greatly reducing the number of lamps. The lamp that was eliminated because the lighting was not up to standard has overcome the problem that the lamp power of the traditional learning lamp can not be overcome is too large; the light source is aging, and the old problem of eye disease or myopia caused by the contradiction is not met. .

2. Applicable people: people with glasses.
3, there are two new features: (that is, the function that traditional learning lamps do not have)
(1) Illumination compliance indication function During the use of the reference intelligent proximity dimming learning desk lamp, the function of the learning environment illumination compliance indicator is to always monitor and prompt whether the illumination of the read/write area conforms to the GB/CIE illumination standard.
(2) When the reading distance of the reference intelligent proximity dimming function is greater than 30cm, the learning desk lamp works in the GB/CIE standard lighting state; when the visual object is blurred, the neck forward is close to or less than the standard reading distance, the brightness of the light increases, until the light The maximum brightness of the tube compensates for the luminous flux acting on the macula of the eyeball, which is reduced by the aging of the lens and the decrease of the light transmittance, thereby overcoming the common and neglected problem of deepening the degree of myopia caused by the aging of the lens.

V. Conclusion and discussion 1. About green lighting. The time to promote green lighting is not short, however, what is green lighting? There is currently no consensus. Some experts say that "green lighting is ultimately energy saving." Of course, this is a statement. The author believes that: (1) Green lighting should contain at least three elements: one is to meet the standard, the other is energy conservation, and the third is environmental protection; (2) the basic principle of green lighting is energy saving and compliance; (3) the minimum principle of green lighting is lighting. Meet the standard. This is the starting point and destination of a new generation of lighting fixtures based on the basic characteristics of “illumination level indication function + reference intelligent dimming functionâ€.
2. About our work. According to the basic principles of green lighting and its current lighting technology, this paper proposes and solves the above four problems, thus forming a new generation of lighting fixtures with the basic characteristics of “illumination level indication function + reference intelligent dimming functionâ€. Rather than a smart dimming lighting control system. However, its structure is simple. For example, the lighting of the workshop or classroom using the coefficient method or the specific power method is a self-contained reference intelligent dimming lighting control system. Each lamp is matched with the brightness of its environment (including the lamp) in real time. Therefore, in the sense of the lighting standard, the basic principle of green lighting is always consistent with energy saving and compliance. Compared with the current domestic and international intelligent lighting control system based on “Scene Preset†[1-3], the equipment is simpler, the light source and the environment are more closely matched, which is more energy-saving, more cost-effective and more reliable. Applicable to all occasions with lighting standards, such as shopping malls, offices, classrooms, laboratories, highways, learning lamps and so on.
3. Copyright issues. The author has 8 patents, the first innovator and founder of "Initial Change, Variable Structure, Quasi-Chaotic Algorithm" and "Cumulative Transformation of Dense Signal Sorting", "Anti-Jamming Theory and Method" (Monograph) A book that knows that the key to innovation is to ask questions; the second is to solve problems. It is gratifying that after the authorization of this group of patents, there are already four (more online) learning lamps in Chengdu Light City, which are said to have the function of indicating the illuminance of the learning environment. It is obvious that the above-mentioned problems raised by us have practical value. We bought two of them and the test results! This kind of use and not cited, obviously hurts the user, but also hurts himself: lack of academic ethics, but also violates copyright law, how can it become a big device! If you contact us, we will deal with it rationally to develop this new technology, because the life of science lies in the application.
