Energy-saving light switch life increased to more than 300,000 times

Fluorescent energy saving lamp is the common name of our common energy-saving lamps and fluorescent lamps. It is a kind of light source that emits light through phosphors and belongs to cold light. Due to the low working temperature, the conversion rate of light energy is high and the energy-saving effect is achieved.

Li Liqun embarked on the road to research and development of energy-saving lamps, entirely because of an accident. In 2009, a friend's energy-saving lamp production line was put into operation in Guangdong, and in order to open up the market, he proposed a marketing strategy that will be replaced within one year. In this way, the sale of energy-saving lamps of friends was really opened, and the sales volume soared. However, what everyone can't think of is that by the end of the year, a friend has lost money. The reason is that the recovery rate of energy-saving lamps actually exceeded 20%, so a friend found her and hoped to help solve the problem of prolonging the lifespan of the energy-saving light switch.

It turned out that whether for world-class brands or domestic self-owned brands, fluorescent energy-saving lamps can withstand 4000 times the switch, the equivalent of 8000 hours of work, is a qualified energy-saving lamps. Take a 13W energy-saving lamp as an example, the current market price is between 25-30 yuan. Therefore, despite the fact that energy-saving lamps perform well in power saving, the imbalance between high selling prices and low service life has been the crux of the promotion of energy-saving lamps. As an environmental management engineer, Li Liqun has always had an environmental protection account in mind: Taking 13W energy-saving lamps as an example, each 13W energy-saving lamp consumes 5 milligrams of mercury, and in 2011, the number of energy-saving fluorescent lamps produced in China was 6 billion. Consumes more than 6 tons of mercury. “In less than two years, this 6 tons of mercury will be basically discharged without treatment. Year after year, it will not only cause great damage to water and soil, but also cause harm to human health.” Li Liqun told reporters The initial starting point for the research and development of high-life long-term energy-saving lamps is to reduce the burden on the living environment as much as possible.

However, it is easier said than done in the world to break through a problem that many world-class brands cannot solve. Li Liqun and her technical team have discovered through research that the direct cause of the impact on the life of energy-saving lamps is that the fluorescence of the fluorescent lamp at the start of the electronic powder on the surface of the filament is detonated. During each start-up process, due to the impact of the current, the electron powder is devolatilized by the surface current of the current and adhered near the lamp cap. When the lamp head gets darker and darker, it means less and less electron powder is left after being detonated. When the lamp head is black to a certain extent, the life span of the energy-saving lamp will come to an end. "Inhibiting the electron powder from being detonated is the key to improving the life span of energy-saving lamps." Li Liqun said. In order to concentrate on her studies, she quit her job in Guangdong and returned to Nanning, where she purchased a large number of reference books and collected common brands and varieties of energy-saving lamps on the market for analysis. After two years of research and development, the company has exhausted 500,000 yuan of funds raised by itself. After experiencing numerous failures, in 2011, Li Liqun and her technical team finally unveiled the mystery of "suppressing electronic powder from being evacuated." Breaking through this world problem, the conventional switch life of energy-saving lamps has reached more than 300,000 times, and the working life has reached 60,000 hours. Currently, the energy-saving lamps on the market generally have a switching life of 8,000-10,000 times and a working life of 8,000 hours. They have been extended by 30 times and 8 times, respectively, breaking the limit that energy-saving lamps are not suitable for use in electronic remote control switches, allowing lighting on corridors to be replaced for two years or longer.

Voice-activated lights can use energy-saving lamps In February 2012, Li Liqun established its own company, while improving the "suppression of electronic powder was detonated" technology, while preparing for the preparation of high-life long-term energy-saving lamp product development and availability of preparations.

"I want to make the best energy-saving lamps." Perhaps because of the relationship between environmental protection and technology research and development for many years, Li Liqun has an unusual attachment to quality requirements. She said that although most of the energy-saving lamp boxes on the market today are marked with the "pure tricolor" logo, many are not using pure trichromatic powder in order to reduce costs, but some are halogen powder or halogen powder and tricolor. Powder mix powder. This is because the price of the halogen powder is about RMB 120/Kg, and the selling price of the Class A tricolor rare earth phosphor is RMB 1600/Kg. Because of the halogen powder and the mixed powder, the light efficiency, color rendering, luminous flux maintenance, etc. are far inferior to the pure trichromatic powder. We usually distinguish between halogen powder lamps and three-color energy-saving lamps. The simplest is to The lighted three-color light shines on the palm of one's hand, and the palm of the hand is ruddy; the light on the palm of the hand is light blue and has no blood. "An energy-saving lamp needs to use about 2g of phosphor. The cost of phosphors for inferior energy-saving lamps is almost negligible, while the investment for a single brand of energy-saving lamps requires about 3 yuan." Li Liqun told reporters that she insisted that Products use Class A phosphors and the best electronic accessories to maximize the life of energy-saving lamps.

From the second half of 2012, Li Liqun's company began to market its products tentatively in small quantities in a free-to-use manner. “At first, no one believed that energy-saving lamps could have such a long service life. Some electricians of property companies think that we are just empty gimmicks. No one believes that the voice-activated lights in corridors can use energy-saving lamps.” Li Liqun Said that voice-activated lights due to frequent switching, many well-known brands of energy-saving lamps will be reminded in the outer box does not apply to voice-activated lights or remote lights. However, Li Liqun’s energy-saving lamps do the opposite, specifically on the outer packaging box: apply to remote control lights, voice-activated lights. Li Liqun firmly believes that a good lamp will "speak". She used the oldest method: comparative testing. In the trial area, one residential building all uses her energy-saving lamps, while the other two residential buildings use other brands of energy-saving lamps. From last year's trial in July last year, Li Liqun's energy-saving lamps are not bad, and other residential buildings are generally two months or even a month to change lights.

Fortunately, the product slowly gained market recognition. In the promotion, many enterprises in Shenzhen, Guangdong Province have already tried and feedback is good. Some companies have started to place orders.

Persevering in the heart of environmental protection dreams and Li Liqun together, the people around him are easily infected by her environmental awareness. Every time you go out to eat, you will pack the rest of your meals and go home; you will be categorized as rubbish; you will also have several techniques for dealing with heavy metal pollution... “We must do our best to use what we have learned. The environmental protection business of the country fulfills the responsibility of an environmental engineer.” With such a spirit of support, Li Liqun is firmly on the road to the development of high-life long-term energy-saving lamps. "Each of the 13W energy-saving lamps needs to consume 5 mg of mercury, consume 1 kwh of electricity, and other materials and energy. If the country promotes this technology, the life of fluorescent lamps will be extended at least 10 times, the country will lose 6 billion per year A fluorescent lamp, which will play a big role in protecting the environment,” Li Liqun said.

However, Li Liqun also has the same distress as many entrepreneurs: insufficient funds. For a tiny company with a core patented technology, how to get more financial support is what she thinks most often every day. Li Liqun has his own regrets: Since she is not aware of the various requirements for applying for a patent, her technology that could have applied for a patent for invention has only been applied for as a utility model patent. This has greatly affected the current collateral for her loans. “When it was the most difficult time, I once wanted to transfer the patent out once and for all, why it was so hard. But at this time, I always felt like I had to sell my own child and I didn’t know if the person who bought it would It is good, and my other wishes will not be fulfilled after the sale.” Li Liqun’s other desire is to establish a recycling and harmless treatment line for energy-saving lamps after the company has grown. “The cost of recycling and decontaminating an energy-saving lamp is a dollar. It requires strong financial support and it is entirely public welfare. I hope that I will have the opportunity to do this in the future,” Li Liqun said.

Although the process of entrepreneurship is very hard and difficult, Li Liqun still does not forget his responsibility to society. After she plans to celebrate the Lunar New Year in the Snake Year, she will fund a six-story secondary school to transform the light source. By then, all of the school's light sources will be replaced by Li Liqun's high-lifetime energy-saving lamps. “I want to let children learn in the softest light, but also to establish environmental awareness from their childhood. This is a corporate social responsibility.”
