At the same time as the development of LED light source technology, Professor of Shanghai Normal University and General Manager of Shanghai Hailong Optoelectronics Technology Co., Ltd. and his team are also constantly developing the patented technology of high-power spherical fluorescent lamps, making this kind of lamp become China. People invented and perfected the fluorescent lamp type for mature application, which was branded by the Chinese; and achieved the result that the experts were convinced and the customers loved in the long-term and large-scale industrial and mining applications. This spirit of persistent scientific research and practice deserves our lighting science and technology personnel to learn.
Fluorescent lamp technology still has strong vitality and broad application prospects. People can't help but ask: Why is this? Please read the paper "Innovative Development of Fluorescent Lamp Technology" to answer your questions!
Innovative development of fluorescent light technology
1. Fluorescent lamp technology is the basis for human invention of artificial light source
1.1 Fluorescent lamp spectrum is the light source closest to the natural light of the sun
In 1938, GE invented fluorescent lamps in the United States. It has been 80 years old. It analyzes the emission spectra of various light sources. The fluorescence spectrum is closest to the daylight spectrum, and it has excellent full-spectrum characteristics. In addition, fluorescent lamps are favored for their high luminous efficiency, light color choice, small heat radiation, long life and other characteristics, and soon become the mainstream of artificial lighting sources.
1.2 fluorescent lamps are still the largest artificial light source in the field of lighting
Fluorescent lamps always have a very high occupancy rate in artificial light sources. Among the total luminous fluxes produced by artificial light sources, the occupancy rate of fluorescent lamps is as high as 80% at present; there is still about 60% of the total.
In 2014, due to the rise of new light sources such as LEDs in China, the total output of China's fluorescent lamps was still 0.69 billion. In 2014, the total output of HID lamps (metal halide lamps, high pressure sodium lamps and high pressure mercury lamps) was 151 million.
In 2016, the total output of fluorescent lamps was 4.023 billion. In 2013, the annual output of rare earth energy-saving fluorescent lamps in China was 4.374 billion, accounting for about 1/3 of the world's total output. (The above data is for reference only)
Therefore, fluorescent lamps are still the largest artificial light source in the field of lighting in China and the world.
1.3 fluorescent lamps are traditional light sources with a long history
Looking back on the development history of fluorescent lamps for eight decades, fluorescent lamp products and technologies have been continuously improved, making traditional fluorescent lamp technology more and more perfect and mature. Mainly reflected in the following aspects:
â—‹ Use rare earth trichromatic phosphors instead of halogen powder to improve light efficiency, luminous flux maintenance rate and color rendering.
â—‹ Reduced lamp diameter, enhanced UV radiation inside the tube and improved light efficiency.
â—‹ Compact fluorescent lamps and thin tube diameter T8 and T5 straight tube fluorescent lamps have been successfully applied.
â—‹ Fluorescent lamp filament adopts three-spiral filament, main and auxiliary triple-helical filament, etc., and the matching electronic powder is improved.
â—‹ Start using amalgam (solid mercury) instead of liquid mercury, control the amount and recover mercury.
â—‹ Fluorescent lamps are driven by high frequency, and electronic ballasts are used to improve the performance of fluorescent lamps.
â—‹ The production process of fluorescent lamps is continuously improved and improved, and new processes such as water coating powder and Al protective film are applied, and automated production equipment is rapidly developed and applied.
â—‹ Fluorescent lamp standard system is increasingly perfect.
The traditional fluorescent lamp technology has been improved and improved by the above eight technologies, which not only retains the characteristics of traditional light sources and has unique advantages; the long history of the traditional fluorescent light source technology matures; we can objectively say that fluorescent lamp technology is experienced after time assessment and actual Apply an approved lighting source.
　
2. Short board exposed by fluorescent lamp technology during development and application
The advantages of fluorescent lamp technology in the development and application process are obvious. At the same time, there are various short plates exposed by technical performance indicators, application range and best cost performance. These three short plates hinder the development of fluorescent lighting and Competitive with other electric light sources. In particular, the rise of new light sources such as LEDs has made fluorescent lamp technology under severe pressure in the development and application process, and is gradually being marginalized. Some people even propose to completely replace and eliminate fluorescent lighting, which is really "awesome."
This paper carefully analyzes the shortcomings in the development and application of fluorescent lamp technology, and proposes a "go to short board".
2.1 Fluorescent lamp technical performance indicators exposed short board
The main defects and limitations of fluorescent lamp performance indicators are shown in the following three aspects:
2.1.1 Fluorescent lamp single lamp source power is small
Common fluorescent lamp single lamp source power: straight tube type: 4w ~ 110w, compact type: 5w ~ 105w.
Single light flux: <10000Lm.
2.1.2 Fluorescent light source life is not long enough
The general fluorescent lamp source life is 6000 ~ 8000h;
The service life of the supporting electronic township is generally about 3 years, which is quite different from the long-life light source.
2.1.3 Fluorescent light source will have mercury pollution during production and use, which is difficult to recycle and handle.
In the current situation of increasing environmental protection requirements, the further promotion and application of fluorescent lamps have been affected.
2.2 Fluorescent lamp technology is suitable for short plates exposed in the application range;
"Fluorescent lighting" is used in the field of lighting, and there are still defects and application limitations, especially in the field of industrial lighting and more clearly magnified its defects.
2.2.1 "Fluorescent lighting" generally applies to a height of only 3 to 6 m indoors. If the height of the plant is more than 10m, it is difficult to meet the design and use requirements.
2.2.2 “Fluorescent lighting†lacks high-transparency flat-panel lighting fixtures, which greatly affects its application.
2.2.3 “Fluorescent lighting†is very sensitive to the ambient temperature and is generally not suitable for use in high temperature environments.
2.3 Fluorescent lamp technology to achieve the best cost-effective exposure of the short board
High-quality fluorescent lighting equipment has good performance and high price, and the cost performance of equipment is not high.
The performance of high-quality high-transmission spherical fluorescent lamps and matching lamps is recognized as good, but expensive, greatly limiting and affecting the application of high-transmission spherical fluorescent lamps in the field of lighting.
In recent years, fluorescent lighting has to face the continuous development of LED light sources and the rapid rise of various emerging light sources, and to adapt to the further improvement of lighting performance indicators, energy saving levels and environmental protection requirements. Low cost performance is also one of the reasons for the declining dominant position of traditional "fluorescent lighting".
3. Two major technological innovations in fluorescent lamp technology
While fully affirming the advantages of traditional fluorescent lamps, we must also objectively notice the shortcomings of "fluorescent lighting" itself, its short board.
In the past ten years, the two major technological innovations of fluorescent lamp technology have enabled the fluorescent lamp technology to continue to innovate and develop in the process of “compensating for the short boardâ€; and through self-improvement through supplementing the shortcomings, the fluorescent lighting can be reborn and developed. !
3.1 The first major technological revolution in fluorescent lamp technology.
It has been almost 30 years since 1974. The development of fluorescent lamps relies on three major technological innovations: rare earth trichromatic phosphors, compact and thin-tube fluorescent lamps and fluorescent electronic ballasts. With these three technological innovations, people completed the first technological revolution of fluorescent lamps.
3.1.1 Rare earth trichromatic phosphors are an important milestone in the first technological revolution of fluorescent lamps
The application of rare earth trichromatic phosphors has greatly improved the performance of fluorescent lighting:
T5 fluorescent lighting effect has been increased to about 104Lm/w;
The color rendering index Ra is increased to 80 or more, and the special use color rendering index Ra can be as high as 95 to 99;
The luminous efficiency is high, the thermal stability is improved, the light attenuation is slow, the luminous flux maintenance rate is improved, and the life span can reach more than 10,000 hours, and the performance indexes of the fluorescent lamps are comprehensively improved.
3.1.2 The successful development of compact and thin-tube fluorescent lamps is another major key to the development of fluorescent lamps.
The thinner the diameter of the fluorescent tube, the higher the UV radiation in the tube, and the higher the light efficiency of the lamp.
In 1938, the T12 (tube diameter 38mm) fluorescent lighting effect was about 50Lm/W.
In 1978, the fluorescent light effect of T8 (pipe diameter 26mm) was about 60Lm/W.
In 1995, the general T5 (16mm diameter) commercial fluorescent lighting effect has reached about 90Lm/W.
There are also fluorescent tubes with thinner diameters such as T4, T3, T2, etc.
In the early 1980s, rare earth trichromatic phosphors were used, and compact fluorescent lamps were born, which reduced the volume of fluorescent lamps. A large number of compact fluorescent lamps replaced incandescent lamps, which once became the world trend. China is still a big country in the production of compact fluorescent lamps. In 2011, China's output accounted for 80% of global production.
3.1.3 High-frequency excitation of fluorescent lamps, the application of electronic ballasts improves the performance of fluorescent lamps
The lighter the diameter of the tube of the fluorescent lamp, the higher the ignition voltage. The T5 fluorescent lamp must use a matching high frequency ballast. In the 1970s, the development of fluorescent high-frequency electronic ballasts was successful, and the high-energy voltage was generated to ignite the fluorescent lamps.
In the 1980s, the popular electronic ballasts for fluorescent lamps used more flow-through electronic ballasts. The power factor was only about 0.9, and the 3rd and 5th harmonics exceeded the standard. The lamp current crest factor is >1.7, and the ballast efficiency is about 0.9. Electronic ballasts are not reliable and safe, and the damage rate is relatively high. (Generally good product life is only 3 years).
Therefore, the performance indicators and service life of high-frequency electronic ballasts need to be further improved. 　
3.2 The second major technological revolution in fluorescent lamp technology.
In the nearly 20 years from 1999 to 2016, fluorescent lamp technology pioneered the second major technological revolution, and achieved four technological innovations to further improve the performance of fluorescent lighting.
It mainly includes the following four aspects:
1. The structure of the compact fluorescent lamp, once again innovative design;
2. Successfully develop high quality long life electronic ballasts;
3. The fluorescent lamp adopts amalgam (solid mercury) instead of fully implementing liquid mercury, and the solid mercury enters the practical stage;
4. Invented the innovative mode of centralized power supply for fluorescent lamps, which made fluorescent lamp technology reborn in the development of innovation.
3.2.1 Compact fluorescent lamp structure is a major technological innovation, and a high-transmission spherical (flat-plate) fluorescent lamp has been successfully developed.
In the 1970s, the compact fluorescent lamp mainly realized the use of a thin tube and a plurality of tubes for bending and folding, which made the volume compact, and has a U shape, a ∠shape and a spiral shape.
But in the 1970s, compact fluorescent lamps brought two problems at the same time:
First, the light inside the tube of the compact fluorescent lamp cannot be unobstructed, the light transmittance of the lamp is reduced, and the light output is reduced, which is usually reduced by about 30%.
In order to overcome the above two shortcomings, Professor Ge Wei and Ge Wei led the R&D team to innovate the structure of the traditional compact fluorescent lamp, and developed a high-transmission spherical fluorescent lamp and a high-transmission flat fluorescent lamp. The "Fluorescent Lighting" performance index, the emergence of compact high-transmission fluorescent lamps, has brought new breakthroughs in fluorescent lamp technology.
Figure 1 and Figure 2 are high-transmission spherical (flat-plate) fluorescent lamps, 4U energy-saving lamps, spiral fluorescent lamps, compact conventional flat-line lamps, and light-emitting ratio of lamps
Figure 1 Comparison of the high light transmission spherical (flat) fluorescent lamp and the traditional flat row lamp exit surface
Compact high-transmission flat-panel tube exit surface Compact traditional flat-line tube exit surface
Figure 2 Comparison of the exit surface of a high-transmission flat fluorescent lamp and a compact flat fluorescent lamp
The high-transmission spherical (flat-plate) fluorescent lamp tube exit surface accounts for about 80%;
The traditional energy-saving lamp tube exit surface accounts for about 50%, and the light output is reduced by 30%.
Fig.3 Relationship between space temperature and luminous flux output in fluorescent lamp tube
Experiments have shown that the light output of a high-transmission spherical fluorescent lamp or a high-transparent flat fluorescent lamp of the same power can be increased by about 50% compared with that of a conventional compact fluorescent lamp or a compact flat fluorescent lamp.
3.2.2 High-performance, long-life electronic ballast developed successfully
Before the 1990s, the half-bridge and flow-by-flow electronic ballasts exposed many defects in practical applications. Until the 1990s, the composite pump circuit electronic ballast and active filter circuit were invented. Improve the technical performance indicators of fluorescent electronic ballasts: power factor ≥ 0.99, lamp current crest factor ≤ 1.4, lumen coefficient ≥ 0.9, as well as filament preheating, anti-electromagnetic interference and various anomaly protection, intelligent control and performance standards All of them have reached a high level, and the high-performance, long-life electronic ballasts that can be guaranteed for six years have been successfully developed and passed the national 3C mandatory standards.
Researchers such as Yang Changgen, Bao Jinxiong, Chen Huizhen and Ge Wei analyzed the problems of electronic ballasts in the eighty and ninety generations of the last century, half-bridge and flow-by-flow circuits, including electronic ballasts for composite ballast electronic ballasts. In order to achieve long life and improve reliability, several important technological innovations have been realized:
1 Reducing the operating temperature of electronic ballast heating components is the core of extending the life of electronic ballasts. The high operating temperature of the heating components can seriously affect the reliability and service life of the electronic ballast. For the main heating components in the ballast, analyze the impact on the life of the whole machine and determine the weight factor value. It provides a basis for redesigning the design of long-life, high-reliability fluorescent electronic ballasts, bringing electronic ballasts to a whole new level. The average temperature of the heating element in the long-life, high-reliability electronic ballast is about 20 °C lower than that of the composite pump electronic ballast, and the life can be more than doubled.
2 Further reducing the long-life, high-reliability fluorescent lamp electronic ballast's own power consumption, has achieved the ballast rated power of 8% or less, and the electrical efficiency is as high as 92 to 95%. The power of a single long-life, high-reliability fluorescent electronic ballast has reached 220w/only, with constant power output characteristics. The design focuses on the long-life, high-reliability fluorescent electronic ballast's own protection, and the output and input have multiple protection circuits to ensure safety and reliability.
3 Long-life, high-reliability fluorescent electronic ballasts have been used for more than six years.
4 Long-life, high-reliability fluorescent electronic ballasts and high-transmission spherical fluorescent lamp switches impact 650,000 laboratory data. A life of 50,000 hours of fluorescent lamp installations will be an achievable goal.
In the second major technological revolution of fluorescent lamp technology, the development of long-life, high-reliability fluorescent electronic ballasts has been successful, and it is another innovative breakthrough in fluorescent lighting technology and application.
3.2.3 Amalgam (solid mercury) high-power fluorescent lamps successfully promoted and used
Traditional fluorescent lamps are produced and used in the process of liquid mercury. They have certain pollution to the environment and become a fatal shortcoming of traditional fluorescent lamps. Mercury is a toxic and harmful heavy metal element. If it exceeds the limit requirement, it will pollute the environment and endanger human health. However, the principle of illumination of fluorescent lamps determines that the lamps of fluorescent lamps must contain a small amount of mercury vapor. Therefore, in the past 20 years of fluorescent lamp development, special attention has been paid to the realization of low-mercury, micro-mercury technology and the use of amalgam (solid mercury) technology.
The temperature range required for mercury vapor pressure is strictly required. The increase in mercury vapor pressure increases the light effect of the fluorescent lamp and the light output decreases. If mercury and amalgam alloys are synthesized in different proportions, the optimum mercury vapor pressure at the corresponding temperature can be obtained, thereby obtaining maximum luminous efficiency and stable light output.
Shanghai Aotong Optoelectronics Technology Co., Ltd. firstly used high-transmission spherical fluorescent light source to replace liquid mercury with amalgam (solid mercury), which effectively controlled the amount and pollution of mercury. Amalgam (solid mercury) high-power high-transmission spherical fluorescent lamps are put into practical use.
In China, the application of amalgam (solid mercury) has mainly focused on the following two aspects in recent years:
(1) The output of fluorescent lamps in China is about 6 billion. According to the industry standard issued in China in 2008, the mercury content of compact fluorescent lamps should not exceed 5 mg/head; the mercury content of straight fluorescent lamps should not exceed 10 mg/head. In 2010, the European Union RollS issued a directive in 2010 that the mercury content of compact fluorescent lamps of less than 30w from 2013 should not exceed 2.5mg/head. We have now developed a 180w compact fluorescent lamp with a mercury content of 1.5mg/head. The compact fluorescent lamp of less than 65w contains no more than 1.0mg/m of mercury. The amount of mercury in the fluorescent lamp is effectively controlled.
(2) China has begun to recycle scrap fluorescent products, strengthen the treatment of mercury-fixing wastes, and effectively control mercury pollution, greatly reducing environmental hazards.
The second major technological revolution of fluorescent lamp technology has effectively controlled the mercury consumption and mercury pollution of fluorescent lamps, and also paid attention to the treatment of mercury-fixing wastes, effectively preventing environmental risks. Fluorescent lamps have become a new generation of green products that are both energy-saving and environmentally friendly.
3.2.4 High-performance fluorescent lamp centralized power supply innovation mode was successfully developed
In 2016, Prof. Ge Wei and Yang Changgen, Bao Jinxiong and other technicians developed a successful patent, a high-transmission spherical fluorescent lamp centralized power supply innovation mode, and fluorescent lighting technology and application added a major achievement.
High-transmission spherical fluorescent lamp is a comprehensive light source with good performance in the field of fluorescent lamps. It has a compact high-transmission spherical structure, high power, high luminous efficiency, high light utilization efficiency, uniform spherical illumination, high color rendering index, stable color temperature and consistency. More than ten advantages, such as good life, long life, high efficiency and good adaptability to lamps.
However, when the application of high-transmission spherical fluorescent lamps is widely promoted, the main bottleneck is that the manufacturing process of high-transmission spherical fluorescent lamps is complicated and the performance requirements of products are high, resulting in expensive products, and the “demand side†is difficult to accept. Very limited.
The “supply side†reform of high-transmission spherical fluorescent lamps adopts a centralized power supply innovation model, which mainly solves the bottleneck of high price in the promotion and application of “demand sideâ€. It can greatly reduce the engineering cost of lighting equipment, and can meet the market demand for deepening industrial lighting energy-saving renovation in the industrial lighting field.
At the same time, through the technological innovation of the centralized power supply innovation mode, the safety, reliability and longer service life of the high-transmission spherical fluorescent lamp are further improved, and the product quality is further improved.
1 High-transmission spherical fluorescent lamp adopts centralized power supply mode design idea:
The original AC (low frequency)-DC-AC (high frequency) electronic ballast is divided into two parts:
(1). Power supply: AC (low frequency) - DC
(2). Driver: DC-AC (high frequency)
The schematic diagram of the centralized power supply innovation mode is as follows

Figure 3 is a schematic diagram of four products for innovative electric mode.
1 The high-transmission spherical fluorescent lamp adopts the centralized power supply innovation mode with four characteristics:
With three primary color fluorescent lighting quality advantages: good comfort, good color rendering, close to natural light.

4.3.1 Industrial lighting
Although the energy-saving retrofit of industrial lighting in China has been implemented many times, the current status of industrial lighting is still a large number of high-energy-consumption electric light sources. The incomplete statistical results of the relevant industrial lighting lamps are as follows:
Quartz metal halide lamp occupies about the amount of light: 60 ~ 70%
High-pressure sodium lamp, high-pressure mercury lamp, energy-saving lamp, incandescent lamp, etc. occupies about 20~25%
High light transmission spherical fluorescent lamp, electrodeless fluorescent lamp and LED lamp occupying the lamp amount: 5~10%
At present, in the field of industrial lighting, there are 60 to 70% of high-energy light sources still in use. If “fluorescent lighting†is used instead, there is a huge potential of saving 40-60%!
Current fluorescent lighting is used to deepen the feasibility of industrial lighting energy-saving renovation:
Fluorescent lighting has passed the second major technological revolution of fluorescent lamp technology, and the new generation of industrial lighting fluorescent lamps represented by high-transmission spherical fluorescent lamps has gradually matured into technology, achieving technical upgrading to meet industrial lighting requirements, high power, high luminous flux and long The energy-saving fluorescent lamp lighting technology bottleneck has been broken: the high-transmission spherical fluorescent lamp adopts the centralized power supply innovation mode, which mainly solves the bottleneck of high price in the promotion and application of the “demand sideâ€, and the production cost is greatly reduced, and the cost performance of the product is comprehensively improved. . In order to cooperate with the deepening of industrial lighting energy-saving renovation, various preparations have been made and good conditions have been created. "Fluorescent lighting" has created a new situation in the field of industrial lighting.

4.3.2 School classroom lighting
The current situation of classroom lighting in the country, most of the classroom lighting has not reached the "national standard". In the past 30 years, China has repeatedly formulated classroom lighting design standards, and the actual non-compliance is still widespread.
The first time was in 1986, in the "Standards for Lighting and Lighting in Primary and Secondary Schools" (GBJ99-86), the illumination requirements of classroom desks reached 150Lx; the blackboard required to reach 200Lx.
The second time was the release of the new "Architectural Lighting Design Standards" in 2004. The classroom desk illumination requirements reached 300Lx; the blackboard illumination requirements reached 500Lx.
The third time is in the "Standards for Lighting and Lighting Sanitation in Primary and Secondary Schools" GBJ7793-2010 in 2010. As the actual situation is still not up to standard, it is re-emphasizing that the illumination requirements of classroom desks reach 300Lx; the illumination requirements of blackboards reach 500Lx.
The fourth time is the release of the new "Architectural Lighting Design Standards" in 2013. The standard stipulates that the classroom desk illumination requirements should reach 300Lx; the blackboard illumination requirements should reach 500Lx.
For a long time, the lighting conditions of classrooms in China are relatively backward, and the illumination of the desks and the illumination of the blackboard are generally lower than the illumination values ​​stipulated by the national standards. Students are learning in low light for a long time. It is bound to cause visual fatigue, poor visual environment in the classroom, and low illumination is one of the important reasons for students' low vision and the formation of students' myopia.
The country has repeatedly asked for and set clear standards for school classroom lighting. What causes so many school classroom lighting that it still does not meet the “national standards�
One of the important reasons is that school classroom lighting fixtures are highly demanding, including lighting comfort, energy saving and safety and reliability, and products that meet the requirements in all aspects are rarely seen. The high-transparency flat-panel lighting fixture is equipped with a centralized power supply innovation mode, which is a compact high-transmission flat fluorescent lamp specially designed for school classroom lighting.
寛 U-shaped high-transmission flat fluorescent lamp and flat fluorescent lamp are shown in Figure 4 and Figure 5.
Figure 4寛U-shaped high-transmission flat fluorescent lamp tube Figure 5寛U-shaped high-transmission flat fluorescent lamp
It adopts 90w寛U-shaped high-transmission flat fluorescent lamp. As the classroom desk lighting of the school classroom lighting configuration school, the illumination can reach the “national standard†requirement of 300-500Lx.
4.3.3 Office lighting, commercial lighting, road lighting...
The high-transmission flat fluorescent lamp system, like the high-transmission spherical fluorescent lamp system, can better adapt to the application of fluorescent lamp technology in various lighting fields. It is especially suitable for industrial lighting, office lighting, commercial lighting, road lighting and warehouse, logistics lighting, etc. It has a very high cost performance, is an excellent lighting product in the field of lighting, and is a lighting product with strong competitive advantages.
The traditional fluorescent lamp technology, combined with continuous technological innovation, will greatly enhance the competitive advantage of fluorescent lamp technology, and has a wide application prospect, which has made the traditional fluorescent lamp technology new.

1. National GB5034-2014 "Architectural Lighting Design Standards" clearly states: For indoor spaces such as offices, LED light is not recommended as a light source.
According to the US Department of Energy report, LED light sources will need to become one of the mainstream products in indoor lighting applications by 2020.
National GB5034-2014 "Architectural Lighting Design Standards" pointed out: At present, LED lamps are used in the field of industrial lighting, the products are not yet mature, and there are still many serious heat, poor color consistency, poor interchangeability, serious color drift and photobiosafety. The field is also controversial. National "Architectural Lighting Design Standards"
It is recommended that the three-primary fluorescent lamp has high luminous efficiency, long life and good color rendering, and can save about 30% of the illumination power than the LED lamp.
2. The lighting quality has obvious advantages, the lighting environment is comfortable and the light pollution is small.
3. The overall life of the centralized power supply + driver is longer than the overall life of the LED lamp, and it is easy to implement standardization.
4. The price advantage of light source and matching lamps is obvious, only 1/3~1/2 of LED lamps, lighting engineering is low, the weight of lamps is 1/4~1/3 of LED lamps, easy to install and maintain, safe and reliable.
