In recent years, compact fluorescent (CFL) market share expansion, T1? T9 straight, EMS, and special rare earth trichromatic fluorescent lamps, cold cathode fluorescent (CCFL) rear projection high-color fluorescent lamps, low voltage neon, special fluorescent lamps, health light, plant growth lights, electrodeless fluorescent join special rare earth trichromatic phosphors and rare earth phosphor demand appeared year after year of booming sales doubled and good momentum.
Manufacture of light rare earth phosphor with companies focus more on the intrinsic quality and rare earth phosphor powder of comprehensive utilization of technical indicators, from selection of raw materials, solid state reaction, combustion, sol method, gas phase, powder, mixed powder new techniques such as synthetic coating, in particular, the structure of the powder, crystal crystal morphology, particle size, size distribution, specific surface area, thermal stability, conductivity, light source according to the manufacturer's needs and close communication with each other, and gradually resolved Rare and non-rare earth phosphor, narrow band, broadband spectrum compatibility issues. According to different luminescence characteristics, physical and chemical properties, different size, different particle size distribution, for detailed sub-file; Phosphors prepared by different specifications of phosphor, and the optimal allocation of different fluorescent pigeon-holing, powder coated with processing, glass tubes coated with nano-material to block UV, anti-aging protection glass film Feifen, waste management recycling.
Over the years, our fluorescent method of production of cotton from the NOx into non-toxic powder coating is fully harmless green coating of water The new technology saves resources, energy, reduce pollution, protect the environment, widely used in compact fluorescent rare earth, rare earth straight fluorescent lamps, fluorescent ring, square lamps, shaped fluorescent lamp, cold cathode fluorescent lamps, low voltage neon, Electrodeless Fluorescent Lamps.
As the new technology, new materials, new processes, new equipment continue to emerge, to further explore the application of market and further promote the light rare earth trichromatic phosphors with the quality and yield improvement. Other related industries (glass tubes, filament, e-powder, solid-state mercury, etc.) to improve overall product quality.
4. Major R & D results
In recent years, with China in light rare earth trichromatic phosphor varieties, properties and applications have emerged in many scientific and technological achievements, many have achieved industrial production.
Yu Shi-Glass Products Co., Ltd. Development of Rare Earth Elements in the sodium doped lead-free glass tube of new products with independent intellectual property rights. Variety of Qi, specifications, and foreign sole discretion 2.5mm to 21mm, camber control 2 , visible light transmission, conductivity, physical and chemical properties, thermal processing performance and other technical indicators have reached the Philips, Toshiba, GE and other standards , in the peer are top quality and yield.
Beijing Nonferrous Metal Research Institute of National Engineering Research Center for Rare Earth Materials development and production of white LED phosphors account for half of the domestic market. Their new research and development of white LED red phosphor at low color temperature LED light-emitting efficiency and lower color rendering index problem. The product has in practical applications of high brightness, good color, color shift and low cost. They also research, development and production of the PDP powder, luminescent phosphor, etc. type.
Jiangmen Branch Hang Industrial Co., Ltd. a long-term with Fudan University, Zhongshan University and other research institutions to conduct extensive cooperation, development of new products with higher technology content. They produce light with rare earth trichromatic phosphors, in terms of quality, yield and cost-effective and so ranked country in the forefront, maintained long-term market position in the industry at competitive prices. They also recently launched a special white LED phosphor and rare earth full spectrum fluorescent lamps, cold cathode fluorescent lamp phosphor, non-polar fluorescent phosphor, special lamps and fluorescent T8, T5 lamps with rare earth trichromatic phosphors. Effectively solve the narrow-band spectrum of different systems, and broadband spectrum phosphors, rare earth, rare earth phosphor with non-compatible problem.
Fluorescent Materials Co., Ltd. Zhejiang crystal can be set for many years to develop and produce special lighting experience with rare earth phosphors, extensive cooperation with domestic and foreign enterprises, self-development production of UV lamps, low voltage neon, health lamps, plant growth and the use of phosphors for fluorescent lamps T8 fluorescent lamps in high-performance halogen powder mixed with rare earth elements.
LED Technology Co., Ltd. Dalian Lu Ming, research and development of photoluminescent material, has become the International Maritime Organization (IMO) Convention provides luminous safety signs specified products (capacity more than 25 vessels have to use luminescent Self Luminescent safety signs). They recently has developed a broadband white LED phosphor and UVLED phosphor, forming a fairly large-scale chip? Extension? Package? Finished one-stop assembly line.
Zhejiang Sunlight Group Co., Ltd., of Zhejiang Province three friends Electronics Co., Ltd., Foshan Electrical and Lighting Co., Ltd., Xiamen Topstar Lighting Co., Ltd. self-built light with rare earth trichromatic phosphors have achieved large-scale production plant. In which Xiamen Topstar Lighting Co., Ltd. developed high-brightness white LED with YAG: Ce3 + phosphor, specifications, electrical and a new breakthrough. Rainbow Fluorescent Materials Co., Ltd. Shaanxi to the scale of production management experience in TV powder, optimized advanced production technology, expanding the light rare earth trichromatic phosphors with economies of scale.
Particularly worth mentioning is that, with stable product quality and good market reputation, Shanghai Yuelong new materials Co., Ltd., Jiangmen City Branch Hang Industrial Co., Ltd., Hangzhou Daming fluorescent material Co., Ltd, Changshu Jiangnan Fluorescent Materials Co., Ltd., Jiangsu days Color Technology Material Co., Ltd., Wuxi Wei Fluorescent Materials Co., Ltd., Suzhou New Era Fluorescent Materials Co., Ltd., Shaanxi Rainbow Fluorescent Materials Co., Ltd. of Zhejiang Province, and three friends Electronics Co., Ltd. (Quzhou, China Lighting Co., Ltd.), Zhejiang Sunlight Group Co., Ltd., etc. , since 2006, light rare earth trichromatic phosphors with annual sales of more than 100 tons, a record high
