Driven by the double policy of ban and government energy conservation and emission reduction, traditional incandescent lamp manufacturers caught in a sense of crisis have opened up the road of transformation, and have invested in the development of new and old LED filament lamps, and many packaging manufacturers are looking at incandescent lamps. The demand for manufacturers' transformation has also begun to develop LED filament market segments, and LED filament lamps have set off a hot air in the lighting market. Why is the LED filament lamp so popular?
Technology breakthrough 360 degree full-angle illumination stereo light source The emergence of the 19th century tungsten incandescent lamp led the world into the era of artificial lighting. Since the 20th century, the revolutionary new light source LED has quickly become popular in the lighting market due to its advantages of energy saving, environmental protection and long life. LED has become the mainstream lighting source for the future, and is widely used in commercial lighting, industrial lighting, outdoor lighting and so on. However, the development of civil lighting is relatively slow. For many people, LED lights are a new type of light source that has never been heard. In 2008, Japan’s Niuwei Light Source introduced the introduction of LED bulb light bulbs with incandescent lamp prototypes. This phenomenon has been reversed. The traditional appearance and upgraded formula can be seen by people who have seen LED lamps. It is a familiar lighting fixture. Then, candle lights, crystal lamps and bulbs with LED filaments as the light source began to appear in large numbers and were accepted by more and more consumers.
Ordinary LED lamp beads are fixed in a plastic holder cup with a single voltage of 3.0V, and then dispensed, that is, PLCC package. The LED filament process usually consists of 28 0.02W 1016 LED chips packaged in series on a 38mm long, 1.5mm diameter glass substrate, and then the top-end fluorescent glue is used. The LED filament is driven by a current of 10 mA, the voltage is 84V, the power is 0.84W, the luminous flux is 100lm, and the luminous efficiency can reach 120lm/W. If it is matched with a red chip, the color rendering index can reach 95 or more. In addition, the LED filament has the characteristics of small current and high voltage, which effectively reduces the heat generation of the LED and the cost of the driver, and has outstanding advantages.
LED light bulbs can be used to make a variety of small and medium power LED bulbs or candle lights. Usually four LED filaments are used. Two strings and two LED bulbs or candle lamps with a power of 3.6W can be designed. With a luminous flux of 400 lm, it can replace the 40W incandescent bulb.
Compared with incandescent lamps and ordinary LED lamps, LED filament lamps have both advantages and avoid their shortcomings:
1. 360-degree full-angle illumination stereo light source The previous LED light source, such as plug-in LED, patch LED, COB, integrated high-power LED lamp bead, can only be a planar light source without the use of optical devices such as lenses. However, the LED filament breaks through this point, and adopts the micro-hole metal substrate single-sided solid crystal bonding wire technology to truly realize the 360-degree full-angle illumination stereo light source, avoiding the problem that the light effect is caused by the addition of the lens and the light loss result is caused. To meet the customer's full-angle lighting needs, bringing unprecedented lighting experience and more energy saving.
2, high color rendering, high light efficiency blue light red chip package, can make the color display achieve the effect of traditional lighting, improve light efficiency and brightness, replace the traditional blue light plus red and green phosphor to improve the loss of brightness.
3, in line with people's habits with the appearance of light source LED filaments meet consumer demand: when incandescent lamps, energy-saving lamps are still dominated the market, the products that can be accepted by ordinary consumers are lighting fixtures that do not change the habits of the past, LED The filament is fully in line with consumer habits of lighting fixtures.
4. Compared with ordinary LED lamps, the cost is lower. Compared with general LED lamps, LED filament lamps use mainly sapphire substrates and wicks, not non-renewable aluminum and non-degradable plastics. Since only the phosphor is coated on a 0.8 mm sapphire substrate, the phosphor is used in a smaller amount than the conventional package. From the current mainstream models, only 25, 28, and 32 chip packages are used according to the power. Compared with ordinary wattages, the LED chips are used less, and the overall cost is lower than that of ordinary LED lamps.
Domestic enterprises are rushing to produce LED filament lamps in the market. Zhongzhou Optoelectronics has stopped its original LED packaging business since June 2013, focusing on the development and production of LED filaments. At present, Zhongzhou Optoelectronics' LED filament wire production capacity has reached 6 million, and it is produced according to the order. Yu Xiang, the sales director of Zhongzhou Optoelectronics, revealed that Zhongzhou Optoelectronics currently sells LED filaments, and has begun to lay out the production of LED filament lamps.
Recently, Zhejiang Deep Optoelectronics Technology Co., Ltd. announced that it will fully develop and manufacture LED filament bulbs. The production base in Xianju County, Zhejiang Province is mainly used to produce LED filament bulbs, and plans to become a domestic LED filament lamp within two years. Manufacturing leading enterprises. Regarding the production target, the company said: We are characterized by a large number of small-scale production. In this way, we can play a scale advantage in the segmentation field.
Yapule successfully transformed through LED filament lamps. Traditional incandescent lamp manufacturer Yap has tried to find a way to successfully transform LED in recent years. At the end of 2011, it began to invest in research and development of LED filament lamps, which was successfully launched in June 2012. In March 2013, Yapuer optimized its products and established its first production line in Guanghan, Sichuan. In February 2014, it established a second production base in Shanghai. Today, Yap's filament lamp production capacity has reached 4 million / month, this year's target is 10 million / month. At present, Yap has established LED lighting as the main direction for the next three years and plans to go public in 2017. With LED filament lamp, LED lamp lamp, T5, T8 lamp auxiliary belt as the main direction, in 2014, it reached the sales target of 1 billion yuan.
From the successful transformation of Yap'er, it can be seen that the emergence of LED filament lamps in incandescent lamps and enterprises that are conducive to energy conservation and emission reduction is undoubtedly a gospel. Enterprises can use the existing technology and assembly line to produce LED filament bulbs, use the original glass bracket of incandescent lamps to design the connection of LED filaments, incandescent lamps with high light transmission rate of special glass and automatic blown glass bulb production technology, production An incandescent bulb-shaped blister can produce a cost-effective LED filament bulb. This is also the breakthrough point for the transformation of LEDs in incandescent lamps.
Current technology research and development and technical bottlenecks In the Frankfurt exhibition in Germany and the Hong Kong Spring Lighting Fair held in the past, LED filament lamps are not uncommon. It is understood that LED filament lamps have already attracted hot air in foreign markets, mainly in North America, Europe, and South America. However, in the past two years, there have been enterprises that have vigorously promoted LED filament lamps. What are the reasons?
In this regard, Shenzhen Delipu product manager Pu Cheng analysis, first, in the context of the price war of light source LED, some packaging companies hope to obtain market position and profit through differentiated products, and hope to cooperate with downstream manufacturers, Concentrate on the advantages of pushing new products, but can not snatch the market share of existing bulb customers, so many companies have chosen to develop LED filament lamps; second, LED light source products from the initial light efficiency pursuit to light quality, enterprises More attention is paid to the light experience, and LED filament lamps are having this advantage. Third, the domestic packaging process has the ability to mass-produce large-scale production at this stage of development.
At present, the cost price of LED filament lamp beads is relatively expensive, which is manifested in several aspects: material cost, labor cost, efficiency, yield, and research and development cost. For the cost aspect, Yapuer bluntly said that if the filament lamp does not consider the yield, only the material and labor cost calculation, the cost is currently in the 3 yuan stage, specifically the filament 3 yuan / root, the power supply 3 yuan (constant current source), Glass bulbs, packaging, labor, gas, etc. total 3 yuan. Regardless of whether it is calculated by W/$ or LM/$, the current price of LED filament lamp is not obvious in China compared with the ordinary LED light source product, and it is determined by the order quantity. The follow-up will continue to enter the 1.5 yuan phase, and it is estimated that at the end of 14 and 15 early years, it will enter the stage of 1 yuan or less. Yapul said with confidence.
As an emerging technology, LED filament lamps are the norm in the development process. Due to the nature of the company and the different research and development, the difficulties encountered by each company are not the same. Tanggong, a packaging company in Shenzhen Yuanlei, said that it currently encounters difficulties from equipment, non-uniform specifications, process efficiency, product performance, etc. The equipment requirements are modified according to the performance characteristics of the filament, but not on the market. Zhejiang General Zhang, the traditional lighting manufacturer to transform LED filament lamps, said that the key is to increase power. The company is now doing 4W, 6W, 8W, and 10W, 12W, and the luminous flux per WW reaches 120LM. The design of heat dissipation is also the focus of research.
LED filament light is just a hot wind?
LED filament lamp is only a transitional product of incandescent lamp to LED illumination. It is a hot air, which is popular in the industry. In response to this statement, the reporter interviewed some enterprises:
Zhang Wei, general manager of Zhejiang Depth, said that the LED filament lamp is the future lighting. The ordinary LED light source on the market advertises a life of 50,000 hours. There is no basis for it. A product is used for 10 years, it is old and bright, and it is also to be replaced. Therefore, what the market really needs is a cost-effective product. No other LED lamp can match the cost of LED filament lamp. In the future, the price below 10 yuan is the product to be achieved. From the market point of view, LED filament bulbs on the one hand reduce the overall cost of LED lamps, thereby enhancing the competitive advantage of LED lamps and traditional lamps, which is conducive to LED lighting into the ordinary family; on the other hand, its emergence is greatly Conducive to our new product development, and more importantly, LED filament bulbs fully meet the consumer's habitual understanding of lighting fixtures. A large number of talents are developing filament lamps, which will definitely drive the development of LED lamps. The filament lamps will inevitably be active in the lighting market because of their unique performance and price.
Shenzhen Delipu product manager Pu Cheng said that LED filament lamps are transitional products, but it depends on how long this time is. LED filament lamp, used as an art light source in home decoration and commercial lighting, lighting effect is the original intention of customers. Today's LED fluorescent lamps and LED downlights are developed on the basis of traditional lighting structures and usage requirements. That being said, they are also transitional products.
Sun Ming, deputy general manager of Shanghai Yapuer, said that we believe it is the ultimate product of LED bulbs, and it is the perfect combination of LED and traditional light source. The product realizes the true full-axis light, has super high light efficiency, perfect indexing, scientific design, truly energy-saving and environmental protection, and achieves a perfect match with traditional lamps! Its application prospects will be very broad!
Beginning in 2014, the ban on whitening in the United States, China, South Korea and Australia will extend from the existing commercial and industrial fields to the civilian sector. Energy conservation and emission reduction will be implemented in residential indoor lighting. The development of LED filament lamps coincides. actually. The development of LED filament lamps is not necessarily a hot air. Its emergence has a revolutionary significance. As long as it breaks through the technical bottleneck and lowers the cost price, the impact on the LED lighting field will gradually increase in the future, and it meets the needs of some nostalgic people. This part of the market potential is very impressive, and will occupy a part of the market in the future.
