In the past two years, the LED filament lamp has become increasingly hot in the domestic LED lighting market. There are two major trends in the industry. First, at the end of March 2016, LED packaging giant Mulinsen decided to acquire Super Time Light Source. The main reason is that it is optimistic about the booming potential of LED filament lamp market in 2016. Hong Kong Super Time Light Source is the largest LED filament lamp manufacturer in China. At this point, Mulinsen's message is to fully enter the field of LED filament lamps.
Second, the LED filament lamp on the Frankfurt show is a big hit, and the domestic LED filament lamp is fast. Yan Chongguang, a professor at the Shanghai Institute of Microelectronics, Peking University, is optimistic that “the production of filament lamps in China will be about 130-150 million in 2015. In 2016, the filament lamps will increase by 3-5 times. It is inevitable to break through 200 million.â€
Lin Jili, executive general manager of Mulinsen, estimated: “China’s LED filament lamp production has reached 120 million in 2015. I expect to grow to 500 million this year. Each LED filament lamp uses an average of 2 to 3 LED tungsten wires.†Mulinsen enters the LED The development and mass production of filament lamps has greatly promoted the development of LED filament lamps.
As early as the end of 2015, some media exposed Mulinsen and Jingyuan Optoelectronics plans to jointly develop a new generation of LED full-circle filament lamps. At the beginning of 2016, GE equivalent 40W retro LED filament lamps were put on the Wal-Mart Sam's Club. Philips Lighting has launched a 2.3 watt LED lamp in the Thai market with a price of 220 baht for the E14 lamp head, and an LED lamp with a 4.9 watt, E27 lamp head, priced at 290 yuan.
Large domestic and foreign manufacturers have cut into this market, in addition to Philips, Osram, GE, Mulinsen and other large factories, domestic sunshine lighting, Foshan lighting, Shanghai Yaming, Yapuer, Hongli Optoelectronics, Hangke Optoelectronics, Mulinsen, Baishi, LED lighting factories or packaging companies such as stellar Gaohong and Yuanlei Technology have also entered the field of LED filament lamps and added mass production. What are the obvious development trends in the LED filament lamp market in 2016? In the face of the competition of international lighting predators, what challenges and opportunities do Chinese manufacturers have? This article will analyze the readers' opinions and manufacturers' viewpoints one by one.
LED filament lamp market three major trends
At the 2016 Frankfurt Lighting Fair, the LED filament lamp once again successfully refreshed its presence. Not only did the major brands have sales, it was very eye-catching. For example, Fuxing exhibited the Venus head LED filament lamp and the replaceable core. Bubbles, LiquiledsLighting from Taiwan show flexible filament lamps and so on. In the pavilion of several decorative lamps, it can be found that the application of LED filament lamps has been extensive, reflecting the good prospects of filament lamps. In terms of price, the price is also lower, and the current price is basically in the range of 7-10 euros. After interviewing the experts, the author came up with three major trends of LED filament lamps:
First, the 2016 dimming filament lamp is the mainstream product exported to the European and American markets. Professor Yan Chongguang said, "The reason why the European and American markets welcome the LED filament lamp is that it is convenient to replace the incandescent lamp. The LED filament lamp can adapt to the existing dimmer, and the new generation of dimming filament lamp power supply. The chip has been born, which shows that the dimming filament lamp is a clear trend."
Professor Yan pointed out that "European and American markets need dimming filament lamps, but their original dimmers are different. At present, they do not have the power supply for all the dimmers in the world, so they can only be allocated in different regions."
Second, one of the development directions of LED filament lamps is the development of decorative products, focusing on low-power products. The highlight is the innovative design, such as flexible filament, which will become the main development direction of filament lamps in the future. In the view of Sun Shaofeng, director of the marketing department of Mulinsen, LED filament lamp is a cross-border product, which has both energy-saving lighting function and decoration. In the future, consumers who need “energy-saving, full-angle, retro†performance will account for the majority, which will bring business opportunities to large-scale enterprises.
Third, LED filament lamps will develop in the direction of high lumens and high power in the future, and the power will be 20W, 25W, 30W, 35W or even 50W. "Yellow light can replace small wattage high-pressure sodium lamps, white light can replace ceramic metal halide lamps below 150W (because it is solid lighting, color temperature is very stable), and replace 55W-100W energy-saving lamps.
LED filament lamp technology market is gradually maturing
Lin Linliang, executive general manager of Mulinsen, is very optimistic about LED filament lamps. He believes that LED filament lamps have four major advantages: 1. Since the packaged device is a full-circumferential type, the optical loss is small, so the luminous efficacy of the LED filament lamp is higher; The filament of the LED filament lamp is full-circumferential illumination, and the cost of secondary optical distribution is reduced. 3. The LED filament lamp relies on gas heat dissipation, so the metal plastic structure is changed to glass; 4. The LED filament lamp can be easily realized by the HV line structure. Dimming function.
Since its inception in 2008, LED filament lamps have long suffered from heat dissipation, low power and high prices, which is why they have not been optimistic for a long time. Until the second half of 2015, the bottleneck of LED filament lamp technology was broken with the intervention of linear constant current driver IC, and with the gradual maturity matching of materials and equipment such as chips, packaged devices, phosphors, substrates, etc., the development of filament lamps rose to new stage.
Li Zhaohua, general manager of Shenzhen Mingwei Electronics, has always favored the LED filament lamp market. Mingwei Electronics currently offers 7 products to support filament lamps, all of which are in mass production. "Now there are a lot of filament lamp solutions, but which one can achieve inductance 6mH, current 10 mA or 20mA? The current market is difficult to find, our solution can be solved."
Since the launch of the industry's first E14 solution, the SM143, which is a plastic-free switching power supply in 2014, Mingwei has been continuously introducing a variety of products SM7315, SM73152P, SM2082D and so on. In June 2016, the thyristor-free SM73151P and SM73153P dimming chip realized by non-isolated switching power supply will also be introduced. Support EE8.3 transformer, patch and color ring (E14), easy to pass conduction, radiation, and high efficiency (η" 92%).
Process improvements have also made it possible to price LED filament lamps. “At the moment, Mulinsen has cooperated with Jingdian to develop new technical solutions and find breakthrough methods to make filaments cheaper, such as opening the bulb casing with glass, so that the bulb can achieve full-circumferential performance, and the cost structure can be the cheapest. Lin Jili, executive general manager of Mulinsen, said that this may be the main way to reduce the price of LED filament bulbs.
Mulinsen said that the newly developed LED filament bulbs are more cost-competitive, and after saving parts and consumables, the LED filaments account for 50% of the bulb cost, which is a significant increase over the previous LED bulbs, which accounted for only 15% of the overall bulb cost, making LED light source technology Re-direct the cost of the bulb.
Wang Peng, general manager of Baishi Optoelectronics, said that today's filament lamps have paved the way for the latecomers with three years of industry pioneers, and there are still two or three subversive revolutions in the future. In addition, this product is basically mature and stable in technology. So today, the technical end of the filament lamp needs to be solved is no longer a problem, but based on the cost-optimized automated production path and the improvement of product creativity.
Liu Qiwei, the chairman of the Richangjing Group, which specializes in LED filament lamps, announced that the filament lamps we produce can be used to kill ordinary plastic-coated aluminum bulbs. Next, our goal is to completely exceed the bulb products in terms of cost performance. In order to gradually occupy the market.
Industry veterans said that the LED filament lamp market is expected to be in the development stage. Nowadays, the problem of heat dissipation of LED filament lamps, miniaturization of drive power, filament manufacturing process problems, UL certification problems have been basically solved, plus LED Filament cost continues to decline, LED filament lamp manufacturing automation rate and production efficiency continue to increase, creating a boom in the LED filament lamp market.
The magic weapon to win the market: patent and large-scale production
Prof. Yan Chongguang said that “the world needs 9 billion incandescent lamps every year. In 2014, China produced about 4.245 billion incandescent lamps. Once incandescent lamps are completely banned, they must be replaced by cost-effective lighting sources. LED filament lamps are 360. The full-illumination light source of the degree is the closest to the incandescent lamp. The same international standard lamp head, the same glass bubble, high-voltage and low-current LED illumination mode can effectively reduce the temperature of the lamp light emitted by the filament lamp. The filament lamp is a safe LED light source. The replacement of incandescent lamps with filament lamps may be the best option."
The LED filament lamp market is booming, but it is two difficulties in front of Chinese manufacturers, patents and production capacity. According to the survey and understanding, the relevant patent manufacturers with LED filament lamps on the table at this stage include the Japanese oxtail (USHIO), Nichia, Taiwan's Jingyuan Optoelectronics, and the mainland's Ledison. And the traditional lighting international manufacturers also have some patents related through various mergers and acquisitions.
Taking Jingyuan Optoelectronics as an example, since 2006, it has obtained patents for LED filaments in the United States, Europe, the mainland, and Taiwan. For example, several LED chips commonly used in the market are set on a transparent substrate with a bonding layer. It is regarded as the key patent of Jingdian. “Crystal is a well-known LED upstream enterprise in the world. It has more than ten years of strategic cooperation with Mulinsen, and there are many patents on the filament. It is regarded as one of the important partners of Mulinsen in the development of filament lamp products. "Min Linsen executive general manager Lin Jiliang said
Mulinsen cooperated with Jingdian, and later acquired the ultra-era light source, behind the dual layout of technology + production capacity. Lin Liliang, executive general manager of Mulinsen, said: "The ultra-era source LED filament lamp products have obvious advantages, but the SMDLED bulb product line is not a strong point. The two companies' products are just complementary, we can use their LED filament lamps, they can use our SMDLED light source Product.†He further explained that Mulinsen’s acquisition of Super Time Energy is a reasonable business strategy, which not only strengthens the Mulinsen lighting brand strategy, but also enhances the required LED filament production capacity.
Compared with the volume of Mulinsen, it is not easy for other domestic manufacturers to cut into this market. Zeng Lin, executive general manager of Hangzhou Hengxing Gaohong Optoelectronics, admitted that stellar Gaohong had been optimistic about the development potential of filament lamps as early as 2012, and began to independently research and develop filament lamp products in 2012. Through more than three years, stellar Gaohong's filament lamp products have become "mainstream products" from "many consumers do not recognize". Zeng Lin said that the "fire" of the filament lamp product is inevitable, but the filament lamp product still has a lot of room for improvement in terms of technology, process and yield, so the investment needs to be cautious.
Companies with patents and capacity can seize the opportunity of rapid market growth. The rapid growth of Hangzhou Hengxing in this market comes from continuous patent investment, certification and production capacity follow-up. Stellar Gaohong has more than 50 patents for filament lamps. The products have passed more than 10 certifications such as CE and UL. There are more than 50 packaging filament production lines, and the monthly production capacity of the whole lamp is 1.8 million.
As the first Shanghai Yap ear to mass-produce LED filament lamps in China, they are more optimistic about the prospect of filament lamps. According to Su Hui, general manager of Yapuang Lighting Co., Ltd., at present, Yap has 58 national patents in the field of filament lamps, and has invested huge resources and strengths in raw material selection, technological innovation and product performance. More than 3 million sales.
According to relevant media reports, there are nearly 800 related companies producing LED filament lamps in China. However, although the entry threshold is not high, it is not easy to do a good job or to do fine work. It is necessary to work hard to make products and create brands.
