The appearance of "rocket launcher" initiated the research, innovation and development of high-power and ultra-high-power energy-saving lamps in China, and promoted the innovation of energy-saving lamps with electric light sources. It also puts forward a new topic for the supporting project of high power factor and high power electronic ballast in China.
1997, the power factor of electronic ballasts in China has not exceeded 0.93, and the input power is still lower than the matching level of fluorescent lamps. The T 12/60W straight fluorescent lamp introduced by foreign "Jianian" company has just come out, and there is no fluorescent lamp electric light source product above 60W in the world. At that time, the inductive ballast could not start the 4U 85W high-power energy-saving lamp.
Mr. Xian, the boss and sales manager of "Huaxing", asked me if I could design a high-power electronic ballast with three 4U/85W high-power energy-saving lamps and a street lamp with three 85W high-power energy-saving lamps designed by Huaxing at that time.
I was in Nanhai, Guangdong Province for technical cooperation with Polaroid Company, and went to Huaxing with Huang Jiajie, the general manager of the company, to discuss the implementation of the project with Mr. Xian, two responsible persons of Huaxing.
At that time, the electric light source tube of 4U-type 85W fluorescent lamp had just come out, and the starting characteristics, tube voltage, lamp resistance and other photoelectric parameters of the tube were still in the exploration stage. Therefore, it is difficult to match the starting characteristics and technical parameters of high power factor electronic ballast with the lamp and make it. After that, I went directly to Zhaoqing City to discuss the implementation plan with General Manager Shi of Suihua Company, a subsidiary of Fenghua Group, and asked General Manager Shi to cooperate with me to complete my product design.
1999 in may, the first domestic 4U/85W energy-saving lamp with three 260W electronic ballasts with high power factor was manufactured. The power factor measured by Huaxing is 0.995; The crest coefficient is1.45; The third harmonic content is 5.3%; The total content of current harmonics is less than 8%; The input power is 260W. The basic technical parameters such as lamp current, lamp voltage, lamp voltage and lamp resistance of 4U/85W high-power energy-saving lamp are determined, which provides a basis for the technical development of high-power fluorescent lamps in China.
At that time, four 4U/85W electronic ballasts with high power factor were made for Huaxing Optoelectronics and handed over to Mr. Xian. And went to Huatai Optoelectronics, another unit in Nanhai, to provide samples to Mr. Yan and Mr. Yan Guowen of Huatai, which promoted the development transformation and production orientation of Huatai Optoelectronics to high-power 4U lamps.
1999 10 "Huaxing optoelectronics" exhibited the world's first 260W high power factor sample at the Hong Kong International Light Show, equipped with three 4U/85W ultra-high power energy-saving lamps, which caused quite a stir in the electric light source industry at home and abroad.
In the same month of the same year, Huatai Optoelectronics, another household electric light source manufacturer in the South China Sea, which was suggested by me to produce super-power energy-saving lamps with new electric light sources, exhibited a sample of 280W high-power factor electronic ballast I provided to Huatai Optoelectronics at the first International Light Expo in Guzhen, Guangdong, China, and participated in the "Light Expo". And successfully transferred three double H-type 95W compact energy-saving lamps in the world's first grid lamp panel. The input power is 280W and the power factor is 0.995.
At that time, the grid lamp panel was named "Rare Earth Tricolor Grid Lamp King" by Huatai Optoelectronics. At the lantern festival, it was strongly concerned by foreign businessmen who came to visit the Canton Fair. It has aroused great interest in the same industry at home and abroad. Therefore, Huatai Optoelectronic and Huaxing Optoelectronic have achieved certain corporate popularity in the electric light source industry at home and abroad. (Huatai Optoelectronics has also moved towards a virtuous circle of enterprises since then? This has aroused strong repercussions in the development and production of high-power energy-saving lamps and fluorescent lamps in China electric light source industry.
Up to now, the domestic high-power 3U, 4U, 5U, 6U and 8U models are all 36W ~ 65W；; 85W~200W ultra-high power rare earth tricolor energy-saving electric light source and high power factor ultra-high power integrated and split energy-saving lamps have opened the prelude to comprehensive development, production and manufacturing. ...
High-power and ultra-high-power integrated energy-saving lamps, split-type energy-saving lamps and spiral integrated fluorescent lamps are also developing towards the product design direction of high power factor and low crest factor at 220V voltage and 1 10V voltage. ...
At present, the important domestic manufacturers of lamps are: First, Jiangxi Guiya spiral, 3U, 4U and 5U, which came from behind; The second is the capillaries of Zhejiang high-power manufacturers; The third is 4U and 5U in Guangdong Nanhai; Four, Jiangsu part of the energy-saving electric light source production enterprises.
At this point, the domestic energy-saving electric light sources have basically formed the pattern of north and south. It has promoted the vigorous development of rare earth tricolor high-power and super-power energy-saving lamps in China. It has promoted the implementation of "Green Lighting Project" in China. As the origin of high-power energy-saving lamps in Guangdong Province, how to make this project bigger and stronger, do a good job in the development of enterprises, make the products of enterprises go up in grade and scale, occupy a certain market share, and implement a strong alliance instead of fighting alone is an urgent problem to be solved in front of enterprises in the electric light source industry in Guangdong Province. )
Development of high-power energy-saving lamps in China (2) 2008-08-0512:11
The development of high-power and ultra-high-power energy-saving lamps in China has started from the north and the south, and should be standardized, industrialized and serialized in the future. At present, there is no quality and safety inspection organization at home and abroad to implement inspection standards for energy-saving lamps with input power exceeding 65W and grid lamps with input power exceeding1.20 W. Therefore, it is urgent to establish quality and safety inspection standards for enterprises and industries.
I suggest that domestic lamp manufacturers set the lamp size according to the following length specifications:
Capillary tube of 4U energy-saving lamp: tube diameter 17mm. Suggested lengths are: 40W 1 10 mm, 55W 130 mm, 65W 160 mm, 85W2 10 mm, 105W235 mm.
Capillary tube of 5U energy-saving lamp: tube diameter 17mm. Suggested lengths are: 65w135mm, 85w180mm,120mm,150mm.
Capillary of spiral fluorescent lamp: pipe diameter 17mm. The outer diameter of the lamp is 80mm and100 mm; Suggestions: 45W3.5 laps, 55W4 laps, 65W4.5 laps, 85W5.5 laps, 105W6.5 laps, 120W7.5 laps. The distance between the pipes is 5 mm -6 mm.
Capillary tube of ultra-high power spiral fluorescent lamp: diameter 22mm. The outer diameter of the lamp is 160mm. Suggestions: 85W3.5 rpm, 105W4 rpm, 120W4.5 rpm, 160W6 rpm, 200W7 rpm, 235W8 rpm, 265W9 rpm, and the lamp distance is 9mm-11.
Straight tube of single H-type fluorescent lamp: pipe diameter 17mm. Suggested lengths are: 55W5 10/0mm, 85W550,105W850mm. ..
Straight tube of double H fluorescent lamp: pipe diameter 17mm. The suggested length is: 85W480 mm, 105W5 10 mm, 120W530mm.
Straight tube of trihydrogen fluorescent lamp: 22mm in diameter. Suggested lengths are: 120 width 480mm, 150 width 5 10/0mm, 180 width 530mm and 200 width 600mm.
Straight pipe of Sih fluorescent lamp: 22mm in diameter. Suggested lengths are: 150 width 480mm, 180 width 5 10/0mm, 200 width 530mm, 235 width 560mm, 265 width 600mm and 300 width 660mm. It is suggested that such enterprise or inter-industry quality implementation standards should be formulated to promote the standardized industrial production of electric light source industries and enterprises in China. ...
The development of rare earth tricolor high-power and ultra-high-power energy-saving lamps, lamps and brackets in China is very gratifying. However, there are still a few enterprises that focus on making "junk goods" with low-power energy-saving lamps. The nominal input power is 105W, and the measured input power is only 60W. The price tag is only 55 yuan/piece, which is not enough for the normal cost of raw materials. This will damage quality and safety; Harm the interests of consumers; Harm the market; "Garbage" enterprises that harm national dignity should be self-disciplined! The government should formulate relevant measures to remove these "junk" enterprises from the manufacturing industry by compulsory legal means! Give a green light to build China's own national brand products in a down-to-earth manner. ...
Of course, the development of health enterprises in China has also made great progress. In the true sense, the number of enterprises whose input power, third harmonic, total current harmonic content, peak coefficient and lumen coefficient meet the standards is gradually increasing. Nidis technical team is committed to optimizing advanced technologies at home and abroad. Designed high-power, ultra-high power integrated energy-saving lamps, split energy-saving lamps, ultra-high power and high power factor electronic ballasts.
Nexis lighting technology team is self-disciplined to build China people's own brand. Has joined hands with energy-saving lamp production equipment factory. The world's first 30m-long semi-automatic aging test production line is designed, which can be used for 18W~400W ultra-high power and high power factor electronic ballasts to carry out 65℃ high temperature, 260V high voltage, surge impact and on-off tests. The appearance of these semi-automatic aging test production lines with complete functions and aging technical means ensures the quality performance and aging test of product components, whole lamp products and electronic ballasts. The product quality has been verified in the real sense! In order to standardize the aging test of product quality in electric light source industry, advanced production technology experience and advanced production aging test equipment are provided. ...
The current high-power, ultra-high-power integrated and split energy-saving lamps; Mainly divided into "spiral type, 3U type, 4U type, 5U type, 6U type and 8U type; Single H type and double H type. These varieties basically have perfect equipment, supporting production detection means and production capacity in a certain range in China. This will have a great impact on the production of high-quality energy-saving lamps and the provision of high-quality semi-finished lamps with electric light sources in China. ...
Single H and double H of lamps, desk lamps and brackets developed simultaneously in China; 18W~ 100W rare earth tricolor lamps also meet the requirements for mass production.
The models and diameters of rare earth tricolor fluorescent lamps and energy-saving lamps with the above electric light sources are basically close. At present, the shortcomings are: there is no unified performance, technology, parameter standard and parameter standard of lamp reference length in all enterprises. There is a problem of establishing standards for enterprises and industries. In order to solve the problem of standard parameters of lamp reference length, I put forward suggestions to domestic manufacturers of electric light sources to standardize the specifications of lamp reference length. Hope to discuss with domestic electric light source manufacturers ...
At present, there are quite a number of electric light source manufacturers, and the consistency of products is generally poor. The quality of the lamp tube is unstable and the special equipment is not perfect. The detection means are incomplete, the production technology is immature, and the production technology is not enough to pass the cottage-style small, scattered, poor and chaotic production conditions.
Here, I suggest that the manufacturers of electric light source tubes use solid mercury when manufacturing tubes, so as to grasp the consistency of products. Adopt high-quality rare earth tricolor phosphor to improve the light efficiency of the lamp. When the water coating process is adopted, the lamp must be coated to prolong the attenuation of lamp life caused by the interpenetration between lamp glass and fluorescent powder, and ensure the delay of lamp attenuation time and the service life of the whole lamp. ...
What should be emphasized here is the manufacturing technology of filament and the production technology of filament emission material electronic powder. The key technology of filament manufacturing and the production technology of filament electronic powder directly affect the product quality and service life of fluorescent lamps. Key production technology of filament, design and manufacture of ultra-high power and high power factor electronic ballast, powder coating technology of filament electronic powder; Welcome domestic and foreign manufacturers of whole lamps and lamps to have technical discussions and exchanges with me.

Another point that needs to be emphasized is that the filament used for energy-saving lamps and fluorescent lamps in China does not belong to cold cathode. The matching of electronic ballast and fluorescent lamp and the implementation of preheating and soft start technology are very important to the filament life and the whole lamp life!
It is suggested that the preheating and soft start time of high-power and ultra-high-power fluorescent lamps and energy-saving lamps should be about 0.8 seconds ~ 1.2 seconds, and the crest factor of electronic ballast should be below 1.6.
Some people say that after foreign standards are formulated, we will formulate domestic quality implementation standards with reference, and then formulate and implement national standards. I think this statement is not accurate enough! It should be pointed out that after so many years of reform and opening up and economic infrastructure construction, China has made a qualitative leap in economy and science and technology compared with 20 years ago. What we do is not lower than the technical level of advanced foreign countries!
High-power and ultra-high-power energy-saving lamps are the first technology of China people in the world electric light source lighting industry! For our own innovative products, innovative enterprises in China, integrated lighting manufacturing enterprises in China, domestic quality and technical supervision bureau, and relevant experts engaged in ultra-high-power energy-saving lamps, we should formulate implementation standards for quality inspection. And foreign enterprises should carry out quality inspection according to the implementation standards of quality inspection formulated by China, and get the relevant product quality certification certificate issued by China!
Therefore, it can also break the technical monopoly and technical barriers of foreign electric light source lighting industry and promote the foreign trade of high-power and ultra-high-power energy-saving lamps in China ... for the people of China! Fight for China's national industry and brand! ……
It should also be noted that there should be a transitional period of digestion at this stage, which I believe will not be too long.
In my opinion, the future development of high-power and ultra-high-power energy-saving lamps should be developed to high-quality products with high power factor, low crest factor, reduced electromagnetic interference, radio frequency interference and conducted interference, reduced temperature rise and prolonged lamp life.
The development of technology should be in the direction of photoelectric conversion solar energy technology; It is developing in the direction of light control, remote control, induction, stepless dimming, group control and intelligent automatic control series products.
By raising technical barriers, those "junk" enterprises that make "junk" products will be eliminated in time! Those "junk" products will also exit the historical stage from the market. Soon people will get a healthy, optimized and high-quality product market. I believe that Zhongmin will definitely create first-class products and first-class enterprises in product and technical after-sales service! Create China people's own national brand!
