The Horn - Interview with Mr. Kong Linghua, General Manager of Zhongshan Greenman Optoelectronics Technology Co. Opportunity is everywhere, when your ability is limited to drive, you can only watch it slip away. If you can clearly recognize their own shortcomings, you can strive to add their own energy to create better opportunities. From the household appliances industry to the transition of the lighting industry, his transformation, as the Bible says, "When God closes this door, will certainly open another door for you", inadvertently opened the road of exploration of LED decorative lighting, which changed his life, but also the achievement of his career. He is our this issue of the "corner": Zhongshan City, Greenman Optoelectronics Technology Company Limited general manager Kong Linghua.
Into the business God opened another door
"When God closes this door, he will surely open another door for you." --The Bible
Kong Linghua, who graduated from Hubei University of Technology, majoring in polymer materials and engineering, has been working in other companies in the technical field before entering the lighting industry, engaging in areas related to refrigeration appliances. "In the field of refrigeration appliances, I am considered to be the first generation of technicians, when China was still a planned economy, household appliances must have a ticket to buy, while the refrigerator is used as a medical equipment for the storage of vaccines, medicines, and not for home use like now, for putting green vegetables, fruits." In conversation, Kong Linghua recalled to the reporter said that year's situation, the story is meticulous, better than a textbook.
In 1979, the State Council issued "on the expansion of state-owned industrial enterprises management autonomy of a number of provisions" and other five documents, marking the focus on the decentralization of the enterprise reform in the country officially began in 1993, clearly put forward the direction of the reform of state-owned enterprises is to establish a modern enterprise system, and further conversion of the state-owned enterprise business mechanism. Kong Linghua in the state-owned enterprises also encountered the problem of state-owned restructuring, forcing him to switch to the lighting industry, from household appliances to the lamp industry, from a standardized industry to a standardless industry, from the study of electronic appliances to the transition of components, into the lighting industry is pure chance, but just as the Bible says, "When God closes the door, he will surely open the door for you. But as the Bible says, "When God closes this door, he will surely open another door for you." Unexpectedly, this door has unexpectedly become the road to the decorative lighting business of Kong Linghua, which has changed his life.
Exploration, overcome obstacles, step by step
"No one knows beforehand how much power he has, until he has tried. --Goethe
Beginning in the industry, remedial knowledge of optics
From household appliances to lamps, Kong Linghua can be said to be familiar with, in his view, "at that time, household appliances is a strict standard specification, which involves a lot of safety issues, such as: can not be electrocuted, fire prevention and so on. Hard indicators, while the lamp industry does not, light bulbs, energy-saving lamps, tubes, as a component, they appear to be relatively simple," Kong Linghua explained.
From the beginning of the millet bubble, incandescent lamps, although the lamps do not have such a strict standard regulations as household appliances, but after entering the industry, Kong Linghua must make up for the knowledge of optics, with the enthusiasm and persistence of the lamp industry, through self-learning, to understand what is the spectra, brightness, illuminance, lumens, and other technical parameters, which has become the Kong Linghua later opened the "LED decorative lighting". This has become the key to open the field of "LED decorative lighting".
The transition to an unfamiliar field, as well as later for the scientific research of the obsessive attempts, his success, just as Goethe said, "no one knows in advance how much power he really has, until after he has tried to know.
First founded LED energy-saving ideas
"LED devices are probably from 1997 into the field of decorative lighting in China, despite the slow development, but the market can still be found in the LED traces of the earliest batch of LED companies have now been withdrawn from the market, which is a company called 'Fung Guan 's enterprise, at that time is to do color-changing bubble, color-changing tube, which is China's early more famous LED device manufacturers." Kong Linghua added, LED just started as a digital and text display technology is used in large quantities in the home and office equipment, plays the role of indication and display, and only later from the transition from by the display lamp to the field of decorative lighting.
From the beginning of the color-changing bubble, the development of color-changing tubes, and then evolved to the current "guardrail tube", color-changing guardrail tube at that time is extremely rare. "At the beginning of the application is relatively narrow, the price is also relatively high, a one-meter length of the guardrail tube, the price is as high as 1,800 yuan, more expensive than the TV, the profit margin is also very large, but there is a market, there is a profit at the same time, the disadvantages of it slowly emerged, which is one of the key points that I want to talk about later." Kong recalled.
In 2003, Kong Linghua set up Zhongshan Greenman Optoelectronics Co., Ltd., although the market has appeared on the LED device products, but people have not formed the concept of LED, millet bubble, incandescent lamps or more prevalent lamps and lanterns at the time of the product, in the case of bad light, taking into account the small children's backpacks to cross the road safety issues, some people in the backpacks mounted on a small millet bubble to facilitate the walk, but the millet bubble power consumption is very large, but it is also very easy to use. But millet bubble power consumption is very large, this time, Kong Linghua thought, why not use LED, then encountered such a problem, the market did not form the concept of LED, how to promote?
Electricity shortage LED promotion opportunity
In 2004, China's "power shortage" problem, caused the attention of the whole society. Pulling the power limit area from the previous 21 provinces and regions increased to 24, many areas from seasonal power shortages to year-round power shortages, the analysis pointed out that the rapid development of energy-consuming industries to tighten the string of power shortages. This became the opportunity and booster for Kong Linghua's career development.
2003 to 2004, Greenman was founded, based on the opportunity of the electricity shortage, in the two-year promotion period, Kong Linghua took his products through Beijing, Nanjing, Shanghai, Tianjin and other major cities, in response to the government's call at the time, to energy saving as a selling point, "At that time, a hand with a traditional millet bubble, a hand with LED products, left a Electroplating meter, right a projector, so walk through the north and south of China, with the meter for different products test, obviously, a turn fast, a turn slow, who save electricity, who consume electricity, a look clear, but also some people think we are selling meter" Kong Linghua recalled laughing. This process, we slowly have a certain understanding of LED products, the promotion effect is still quite good.
With the deepening of the promotion work, the information received by consumers slowly increased, but also to the Greenman created the opportunity for rapid development, business doubled every day, from the internal researchers, sales staff, to the end of the use of the user, there is a significant increase. In addition to this, a number of competing manufacturers have emerged, and as the market expands, problems are slowly emerging.
Development The invention of LED Guardrail Pipe Plugs
"That which is otherwise hopeless, boldly attempted, often succeeds." --Shakespeare
Cause of the water LED guardrail tube
The 2004 electricity shortage crisis, to China's energy-saving lighting market has brought a new opportunity, but also increased the expansion of the market, attracting many businesses into this industry, small factories around the world such as the emergence of the problem also came up!
The market has been growing for a long time.
The market has no standardized criteria to follow, counterfeit products abound, product quality varies, homogenization is serious, the price competition has also increasingly become a competitive means of merchants competing for the market, how to stand out among the many manufacturers, appears to be critical. Good opportunity plus a good product, in theory, should open up another new opportunity, but unfortunately at that time in the market circulation of generic products disadvantages also followed slowly highlighted.
LED guardrail tube, then extremely popular products, due to its low energy consumption, colorful, and highly favored by the market, in the domestic multiple national highways, roads have installed applications, the use of good results, with the expansion of the use of the scope and frequency of increase, its waterproofing problem is also increasingly prominent. Water problems caused by short circuits, circuit board fire, power plugs abound in the case of combustion, despite the powerful, colorful, but gradually let users lose confidence.
In 2005, although engineers engaged in this area of technical research also realized the problem of waterproof, but there is no effective technical means to make up for this defect. To this end, some people try to play a hole in the lamp above the wire inserted into the wire, and then coated in the edge of the wire sealant, the hole sealed, hoping to play a role in waterproof, but in the wire a pull, the glue is easy to fall off, and at the same time, after the hole, the tube wall was damaged, in the sun for a long time, under the sun, it will be naturally cracked, and finally there will be a problem into the water. "At that time, despite the high profits in this field, the profits were eaten up by the maintenance costs, which also led to a lot of people losing confidence in this product," Kong said.
Try LED guardrail tube plug R & D
LED guardrail tube problems also plagued the development of Greenman, then in Wuxi, Wuhan, Beijing, there are a number of projects under construction, are similarly encountered in the water problem, in 2006, the LED guardrail tube problem is not solved, in the crowd thought it was hopeless, Kong Linghua made a bold attempt to do a lot of things, including the wire tube, circuit boards, the wire tube, the circuit boards, the circuit boards, the circuit boards, the circuit boards, the circuit boards, the circuit boards, the circuit boards, the circuit boards. Including the line pipe, circuit boards are blocked, in the outside of the lamp coated with glue, but after a long time in the sun, the paint will fade, aging, into pulp, affecting the lamps and lanterns out of the light, as a result, the problem is back to the guardrail tube waterproofing problem.
In the process of trying, Kong Linghua did not eat less, but also made a variety of attempts, whether it is from the guardrail tube external adhesive, or internal adhesive, the same did not solve the problem, at this time, Kong Linghua would like to think that the LED guardrail tube into the water at the root of the problem is in the lamp interface, if the waterproofing of the lamp interface is solved, whether it is possible to solve the whole problem? Based on this starting point, bold attempts, often get unexpected success, and Kong Linghua has proved it. Kong Linghua later designed a sealing plug for LED lamps, the design of the plug body edge of the width of the groove is set to be slightly wider than the wall thickness of the LED tube, to facilitate the filling of sealant in the groove, so that the sealing effect of the plug is better; Secondly, in the fixed groove is equipped with a fixed plug body along the side of the signal line and power line through the outlet hole, filling sealant, it is easy to exit the hole with the gap between the wire sealing so that The electronic components inside the lamp will not be oxidized to ensure that the service life grows.
This way, it basically solves the problem of LED guardrail tube into the water, the same year, Greenman in Longyan City, Fujian Province, Shanghang County, a bridge project above the application of this technology, coincidentally, after the completion of the installation, just after the flash floods, everyone believes that this batch of guardrail tube will be scrapped, the results are surprising, after the flood all the guardrail tube are normal light, this success not only inspired the This success not only inspired Kong Linghua, but also caused repercussions in the industry.
Deep plowing LED guardrail tube upgrading
With the successful development of LED guardrail tube plug, the problem of water in the guardrail tube is also basically solved, at this time, there is a new problem - the adhesion of the glue. Subsequently, in order to get rid of the glue is not resistant to the problem of adhesion, Kong Linghua invented the second generation of the whole structure of waterproof LED contour lamp, including a lamp and the end of the end of the lamp at the end of the end cover, in the end of the cover is equipped with power supply line through the threading holes, in addition to lamp connecting ring, the lamp sealing ring, the wire sealing ring and wire sealing ring pressure block. After the combination assembly, it will achieve the purpose of waterproof without any adhesive, which abandons the role of glue on top of the LED contour light.
The third generation of highly waterproof contour light, including a bar-shaped lamp base, lampshade, set in the lamp base and lampshade light bar and lampshade plug at both ends, the light bar consists of a circuit device, light-transparent sealant layer and insulating layer, which light-transparent sealant layer is infused in the circuit device is easy to short-circuit on the metal surface. The use of molten sealant to seal the entire circuit device all easy to short-circuit the metal surface, can play a completely waterproof purpose.
Thinking The Pros and Cons of Modern Decorative Lighting
"Man was created to think." -- Pascal
Decorative lighting, also known as atmospheric lighting, is mainly through some color and dynamic changes, as well as intelligent lighting control systems, etc., in the case of basic lighting, plus some lighting to decorate, so that the environment to add atmosphere. Decorative lighting can produce a variety of effects and atmospheres, giving people different visual enjoyment. In Kong Linghua's view, decorative lighting can be divided into two blocks: one is holiday decoration, one is architectural decoration, and architectural decorative lighting is different from the general lighting, it is artistic, functional requirements are higher, often in some traditional festivals, such as National Day, Spring Festival, Lantern Festival used to set the mood, which not only need to consider the functionality of the practicality of the combination of the intrinsic demands of the local culture.
From the realization of the means of view, the emergence of LED breaks the traditional light source design methods and ideas, so that the decorative lighting more energy-saving and environmentally friendly, humane, intelligent. How to better combine the local culture, retain the original texture of the building design, the use of local cultural characteristics of the lamps to set off, is Kong Linghua recently are thinking about the problem.
1, how to retain the building's own texture design?
Without destroying the structure of the building on the premise of architectural lighting design, on the one hand, to increase the stability of the product, on the other hand, through the product of simple assembly methods, minimize the destruction of the wall on the surface of the building;
2, how to take into account the building landscape during the day and at night the same?
Through the research and development or the use of decorative modeling of the structure of the lamps and lanterns, so that it becomes part of the building decoration during the day, and at night it is good to set off the cultural atmosphere of the building itself;
3, how to better protect the building?
When negotiating with the construction unit or the owner of the cooperation, it is recommended to try to use corrosion-resistant materials, in the absence of alternative products, please try to ensure that there will be no rust. In the past, when installing lamps and lanterns, may be one meter to play a hole, according to the size of the lamps and lanterns, use, try to increase the distance.
Kong hopes to influence his peers in the industry by advocating a concept that will become a rule and standard.
Outlook 2013 reshuffle will be a little bigger
After the melee between 2007 and 2009, from 2010 onwards, China's lighting industry is basically divided into which is the mainstream manufacturers, which are non-mainstream manufacturers. "Every era, every industry will have the status quo of elimination, in 2005 and 2006, also suffered the same business closure status quo, I think the reshuffle status quo is normal, just 2013 will be a little more intense." Kong Linghua said.
The market downturn, corporate chaos, production capacity is much higher than the market expected, on the one hand, some of the larger outdoor projects, such as municipal construction projects, not only need a strong support team, but also need to be strong public relations capabilities, this area is not a general company can be attacked into.
On the other hand, the real estate industry suffered a blow, used as indoor lighting fixtures do not have interchangeability, in the case of non-interchangeability, in addition to the new house needs to use the new lamps and lanterns, generally the old house is full of fluorescent lamps and incandescent lamps, coupled with the average consumer does not have the ability to electrician, do not know how to replace the installation, which causes problems for the promotion of LED lamps and lanterns, it can be said that, cannot Into tens of thousands of households, are not a good product.
Reporter's note "no can't do, only can't think of"
In recent years, the lighting industry in the national policy to promote, as if playing estrogen, showing jumping growth, with the emergence of the LED fourth-generation light source, giving the lighting industry a new opportunity to develop, almost no one will question the development prospects of LED. LED's development prospects, from the LED light source itself has the advantage of a large amount of capital investment in all walks of life, which is undoubtedly the stars, just, how to combine the advantages of LED light source different occasions, the field of play to the extreme, to improve its cost-effective, which may be the next thing we should do.
When chatting with Mr. Kong, I feel that he is quite easy-going and steady, and his words reveal a variety of ideas and expectations for the field of LED decorative lighting, which makes the editor more convinced that the emergence of LED light source, giving the lighting industry unlimited possibilities, it seems that "there is nothing that can't be done, only can't be thought of," in the lighting industry in China, the process of the editor, the editor, the editor, the editor, the editor, the editor, the editor and the editor, the editor and the editor, and the editor, the editor. In the process of the lighting industry with China, the editor is quite looking forward to the innovative application of LED light source, to different areas of the innovation storm, but also look forward to Greenman in the field of LED decorative lighting to create more possibilities.
