In 2012, many companies expect that Guangya Exhibition will bring about a good improvement and make more orders, but basically, many companies are disappointed. In the second half of the year, many LED manufacturing companies still have no choice but to do the worst in the overall external environment. Do you also look to the Light Fair or "Jin 9 Silver Ten" to make a good breakthrough to achieve a certain breakthrough? However, for many LED manufacturing companies, the greater the disappointment, the greater the hope. It is undeniable that most of the company's days are not very good, a realistic survival problem is the LED lighting industry is in the shuffle stage.
In fact, LED lamps and lanterns are the most comprehensive and simplest products in the industry. This also results in lamps that can be simple or complex. Simplicity is because: It is a combination of some hardware products, there is no technical content, can meet the basic characteristics of lamps, and the safety performance is reliable, and the product is a design without a design concept. The complexity is the highly integrated integration of optics, electronic engineering, mechanical structures, chemistry, and thermal sciences. It is not easy for a LED company to solve it comprehensively. In particular, the characteristics of LEDs are better than those of conventional lamps. If thermal, optical and electronic processing are not good, LED lamps should not be said to exert their advantages. Even the most basic lighting requirements are difficult to achieve.
First, the rational era of LED lighting has come Since the elimination of the incandescent light roadmap was announced, the LED lighting sector has become a hot spot in the market. In the short-term interest and an instinctive living environment, many home-based workshops and some short-sighted manufacturers use the public’s support. The blind spot that LED lighting knows not enough, produces some so-called LED lamps, shoddy work; Dispelled the idea that some are willing to try the LED lamp people, has spent more than ten times of the price that the traditional lamp buys LED lamp, can say to only use a lamp for a lifetime Actually, it only took a few months; this situation is more prominent in the ancient town, which greatly restricts the healthy development of the LED lighting industry. Especially in the high-power lamps, no need for patch, just turn around in the accessories city, buy back some of the shoddy kits, assembly can be listed, shipped. So how to make the people buy real LED lamps is the country's current task of regulating the LED lighting market. Of course, another important reason that restricts the popularization of LED lamps in the immediate future is naturally the price and the people’s correct understanding of LED lamps.
In solving people's correct understanding of LED, how to make LED lighting products get consumers' approval? In addition to support at the government policy level, and at the supply side to reduce product prices through technological innovation, the cultivation of consumer environmental protection concepts is also very important. Japan’s LED “green†propaganda is quite new. Its core is to educate the public from reducing carbon dioxide emissions, and it is connected with people’s living and personal health. Many LED publicity occasions can see “If you use this kind of LED light source/lamp, it will reduce the amount of CO2 emitted by your household by kilogramsâ€. Obviously, the people are more concerned about how much less harmful gas they have in their living and working space, rather than how much electricity the country will reduce. In this sense, the people are more willing to pay for their own health, so that LED interior lighting is naturally promoted and popularized.
Nowadays, more and more LED applications begin to march into civilian households. LED advertising and the construction of photovoltaic industry parks everywhere that no one can see today five years ago has greatly improved the LED application status. The most common use of the civilian market is fluorescent and incandescent lamps, and the cost requirements are particularly low, so if the LED lamp is to replace the traditional fluorescent and bulb lamps, we must develop the size of the lamp, power interface, installation methods fully comply with the traditional lamp specifications The lighting effect is the same as or more than that of traditional lamps, and it needs a cost-effective advantage.
Second, product specialization is the ultimate way out At present, China's LED manufacturing companies are still the main market in foreign trade exports and domestic engineering projects; mainly foreign trade exports to the mainland traders, there are a few manufacturers will directly foreign; we can also According to the status quo of foreign markets, they are divided into two categories: primary market and secondary market. The primary markets are the United States, Japan, and the European Union. Their requirements for products are relatively much higher, such as various cumbersome product certifications and light source patents. THD, water lines, etc., the power supply is naturally isolated, and the price is relatively higher; secondary markets such as Russia, India, and South America, their national conditions and China are almost the same, they travel to China, they want to The price, the other requirements are lower, and the product requirements are naturally not high. The requirements for end-customers on domestic engineering projects or in the market are even simpler. In the case of the same price, it is possible to meet the basic requirements of the mainland conditions plus some interpersonal concerns and suit for some engineering renovation projects. At present, the projects that need to be reconstructed in mainland China are nothing but factories, supermarkets, underground parking lots, schools, hospitals, hotels, and advertising light boxes.
The company's products should not be positioned as "people have me" ideas, put into production is best not more than 10 models. Because the product does not have the same direction as the headless flies, there are chaotic strings everywhere; a good product can guide the trend of the market, and a trend; a very cost-effective product can drive and expand the market; so we have to make a very cost-effective High and good LED lamps to guide the market, drive and expand the LED lighting market that is currently in dilemma and unhealthy; cost-effective, good products to be designed from a professional point of view, manufacturing, can not let the market to control you, today customers want outdoor For those who are involved in outdoor activities and want to assemble indoor in the future, the company's people and energy are limited. In the end, it is only the market that is completely led by the nose. Its products have no personality and characteristics, and none of them are His own profession, specialty products; so we hope to do a product must be refined, so that customers feel professional.
Third, the future LED fluorescent light source will be mainly in high-power series Since 2005, China's LED fluorescent tube light source changes have become more apparent, which is mainly with the LED industry as a whole technology upgrades and market demand for LED fluorescent tube has a direct relationship. At that time, the LED fluorescent products were around 500-700 yuan.
After 2008, the percentage of LED fluorescent tubes using the F5 straw hat line series as a light source was rapidly reduced and replaced by other light sources. As of the end of June 2012, the LED fluorescent tubes of the F5 straw hat line series had a market share of less than 0.5. %, only a few companies still maintain a certain amount of production, mainly because their early customers still trust such products. At that time, LED fluorescent lamps were around 300-400 yuan.
In the second half of 2009, 3020 and 3014 as LED fluorescent tube light sources gradually seized 3528 and 5050 parts of the market, and in the same year 5630 medium power began to be used in LED fluorescent tubes by a small number of companies, while 5050 series light sources used in LED fluorescent tubes began to decline; At that time, LED fluorescent lamps were around 200-300 yuan.
From 2010 to 2011, the percentage of LED fluorescent tubes with medium and high power as the light source represented by the series of 2835, 3030, and 3535, LED light sources directly encapsulated on the aluminum tube of the fluorescent tube, etc., has grown rapidly. At that time, LED fluorescent lamps were around 100-200 yuan.
After 2012, the light sources used in LED fluorescent tubes have the coexistence of straw-hat series, SMD series, and COB package series, but their proportion will vary with time and technology, and it is undeniable that the power is high. Light sources will dominate mainstream applications. We predict that LED fluorescent lamps will soon enter the era of about 50 yuan.
1. The current LED fluorescent lamps use more types and advantages of light sources:
A, 3528, 3020, 3014 series products have a single structure, good heat dissipation, small size, no spot in the use of LED fluorescent tubes, and low cost.
B, 5050, 5630 particles larger size, used in the LED fluorescent tube spacing is larger, the resulting spots are too obvious, more suitable for some advertising campaign LED fluorescent tube, light bar, etc., not the best choice for LED fluorescent tube light source.
2. The future LED fluorescent light source will be mainly high-power series:
The medium and high power represented by series such as 2835, 3030, 3535 and COB encapsulation has become a quick way for companies to reduce costs. With the continuous decline in the price of LED fluorescent tubes, the gross profit margin of LED fluorescent tube manufacturers has been greatly reduced. According to data from the GLII research report, the average gross profit rate of LED fluorescent tubes in 2010 reached more than 48%, but by the first half of 2012, this figure has dropped to 26% or even lower. Therefore, at present, many companies indirectly reduce the cost of LED fluorescent tubes by seeking to reduce the cost of light sources. 2835, COB packaged products gradually become one of the main sources of LED fluorescent tube. The 2835 series is a 0.2W series product. Therefore, the number of LED fluorescent tubes used under the same power will be reduced by more than half, and the cost of LED fluorescent tubes will be reduced more obviously; while the COB package will become an LED fluorescent tube due to its high overall luminous efficiency, good spot quality, and low cost. Another option for light sources, and the COB package series will become one of the main light sources for LED lighting applications in the future. For some time in the future, China's LED fluorescent tubes will form LED fluorescent tubes market, which is mainly led by medium- and high-power LED fluorescent tubes and supplemented by 3528, 3020, and 3014 series light sources.
The rapid development of the four-and-five yuan highly integrated LED T8 fluorescent tube solution LED lamps has led us to believe that the original separation method has not met the requirements of modern industrial manufacturing products. The initial stage should be more integrated products. The progress of industrialized machinery manufacturing will increase with the increasing degree of LED light source packaging integration (COB is the premise of the standard module), and the implementation of modularization of LED lamp components is getting faster and faster (Zhaga Alliance is actively promoting LED lamps and lanterns The process of standardization of parts) makes the manufacture and application of lamps easier and more suitable for lighting applications. In the future, LED lamps will tend to develop in two directions. One is a non-replaceable one-piece LED lamp (the height of lamp parts is integrated), and the other is a modular LED lamp that complies with relevant standards (lamp's light source, shell, power supply , electrical connections, etc. are all subject to common interface and assembly standards). The market will first go through a highly integrated stage, and then gradually transition and establish the application phase of LED standard modules. More applications in the future will be the workshop mode of easy assembly and combination of standard modules.
Shenzhen Delip Optoelectronics Co., Ltd., as an LED-driven manufacturing company, combines the needs of the market with its own development philosophy to explore a simpler LED T8 fluorescent tube manufacturing and application improvement. The development concept we proposed is that the LED daylight tube aluminum fittings are suitable for "C" shaped components. Based on a highly integrated mechanism design model, combined with the current mature LED drive technology, LED lighting manufacturers can timely guarantee product quality and application. At the same time, the cost is controlled within 50 yuan, while ensuring a high luminous efficiency, low cost, long-life LED T8 fluorescent tube integrated solutions.
The “Highly Integrated LED T8 Daylight Tube†solution from Delip Optoelectronics has a compact product structure and high luminous efficiency. It uses non-isolated circuits and plug-in LED patch light sources to share a single integrated circuit board, saving production costs and shortening The production time of finished products has made the production pass rate and pass rate higher. This product design meets the market demands and product status of most developing countries.
Structure description:
01, transparent striped PC cover: transparent material striped PC cover, light transmittance of 95% or more, the maximum output of the LED lamp beads stimulated light, increase the utilization of light;
02, SMD components and SMD LED lamp beads: The chip components of Delip's high-efficiency non-isolated power supply are attached to the front of the FR-4, which is based on the consideration of heat dissipation and structure. Delip recommends a SMD LED with a single lumen value of 18-20lm and a power of 0.2W, such as 2835, 5630, and 5730, as the supporting light source for this solution. For cost reasons, the number of lamps is between 72-90. It is appropriate;
03, FR-4 dual-panel: Delip's "highly integrated LED T8 fluorescent tube" is not only considering the use of FR-4 dual-panel from the cost, but also for structural and thermal considerations. The FR-4 double-sided front surface mounts the LED lamp beads with the surface mount components required for the power supply, and the discrete components are mounted on the reverse side. In this scheme, the distance between the LED lamp beads is about 15mm. In this way, the FR-4 plate material can provide sufficient heat conduction area for the LED lamp beads.
04. Circuit discrete components: discrete components (such as ICs, capacitors, transformers, resistors, etc.) mounted on the reverse side of the FR-4. Make full use of the advantages of the structure, have enough space for installation, provide a stable and efficient power output for the light source; apply EMC and non-isolation but EMC.
05ã€Aluminum: Aluminium is a “C†shaped LED daylight tube aluminum. It conducts the heat in the LED lumen by heat radiation, making the LED lamp beads and electronic components work within a tolerable temperature range. The service life of the lamps and lanterns meets the design requirements to minimize the light failure of the LED lamp beads.
According to the above scheme, the cost of the LED T8 fluorescent tube (1.2 meters) is calculated as follows:
The "highly integrated LED T8 fluorescent tube" solution from Delip Optoelectronics is designed to allow more LED lamp manufacturers to establish a shared strategic cooperation foundation, combining drive technology, light source packaging and external kits. We will change the segregation status of the respective industries and reduce the production costs of the manufacturing process, which is expected to promote the process of LED fluorescent tube replacement of fluorescent fluorescent lamps in the domestic market. From the perspective of the existing market, the current price of LED fluorescent tubes is still relatively high, but due to its characteristics of energy saving, environmental protection, and long life, it has been widely used in parking lots, commercial lighting and other fields. According to statistics, the LED fluorescent tube market reached RMB 6 billion in 2011. With the continuous decline in the price of LED fluorescent tubes and the continuous improvement of technology, LED fluorescent tubes are increasingly used in various fields of application. It is expected that the growth of China's LED fluorescent tube market will exceed 60% in 2012. It can be imagined that the market of LED fluorescent lamps is very large. Therefore, from the LED fluorescent lamps, Delip has provided everyone with a solution to the ideas and directions for your reference.
