With the rapid development of LED lighting technology, LED lighting products continue to evolve. Since the invention of the LED filament lamp by the Japanese Niuwei Light Source Company in 2008, some people have been cheering and some have sneered. There are praises and there are many people who are ill, and the industry is mixed. However, the booming development in the past three years has also made people stunned. In the end, is the limelight rising, or is it a short-lived? It is awkward, and let the author make a analysis.
Some time ago, a Shenzhen LED business owner who visited the company just visited the market. After more than half a month of visits, he went to some export enterprises in Jiangsu, Zhejiang and Shanghai. Through contact with the manufacturers, he gave the author a message: that is, the LED filament lamp market has bright prospects, and it is recommended that those traditional lighting manufacturers increase their efforts to enter the field.
According to surveys conducted by authoritative organizations, the total demand for global LED filament lamps in 2015 exceeded 100 million, and it will increase rapidly by more than 35% per year. Once all the incandescent lamps above 15 watts have ceased production and sales from October 1, 2016, the demand for LED filament lamps will continue to increase.
Tracing the source and getting a lot of attention
It is understood that since 2008, Japan's Niuwei Light Source has introduced a bulb-type luminaire equipped with an incandescent lamp prototype - "LED filament bulb", which has attracted attention because of its "traditional appearance, upgraded 'recipe'". In fact, as early as four years ago, there were companies in the country to start research on LED filament lamps, and some manufacturers began to develop and put into production.
According to industry insiders, LED filament lamp is also called LED lamp post lamp. Its biggest advantage is that LED filament realizes 360° full-angle illumination. It does not need to add lens to realize stereo light source. It can be said that it brings unprecedented lighting experience. Of course, the LED filament lamp also has the characteristics of no stroboscopic, no blue light discharge, no hot, long life, slow attenuation and the like.
“At the Guangya Exhibition in June 2013, only Yap and Jingyang exhibited their formal and inverted LED filament lamps. At the Guangya Exhibition in June 2014, more than 60 companies displayed their filament lamps. At the Hong Kong International Lighting Fair in October 2014, more than 200 companies have displayed LED filament lamps of various colors. After the Hong Kong exhibition this year, according to relevant media reports, there are nearly 800 related companies producing LED filament lamps in China. Professor Yan Chongguang from the Shanghai Institute of Microelectronics, Peking University, said.
Good to promote the prospects
The Chinese incandescent lamp elimination roadmap clearly shows that it is forbidden to import and sell ordinary lighting incandescent lamps of 15 watts or more from October 1, 2016. Under the background of the “no-white†policies of various countries, the LED industry is undoubtedly the gospel of seizing the market!
Chen Heng, general manager of Shenzhen Shengpan Green Integrated Technology Co., Ltd. (hereinafter referred to as “Dianpan Integratedâ€) pointed out that after the decantering of incandescent lamps, the industry has been looking for energy-saving products that can directly replace incandescent lamps. Especially obvious. Because incandescent lamps are delisted earlier in developed countries in Europe and America, European and American consumers are more urgent about the demand for energy-saving products that can directly replace incandescent lamps. Therefore, most of the orders for LED filament lamps received by Chinese companies come from European and American countries.
The author understands that in the second half of 2015, LED filament lamps such as Philips, Osram, GE, etc. are also listed! Domestic Buddha Photo, Yaming, Shenan, Yapu Er, Hongli, Zhongzhou, Hangke, Lehman, Mulinsen Incandescent lamp manufacturers, LED lighting factories or packaging companies such as Baishi, Stellar Gaohong and Yuanlei Technology have entered the field of LED filament lamps and added mass production.
Technical weakness is not expensive
Although the LED filament lamp has the potential of smashing the original, the problems in the production process can not be ignored: the manufacturing difficulty is high, several different processes need to be integrated, and the yield is low. The LED filament lamp exceeding 8W is prone to heat dissipation; Broken, easily damaged during the production process and during use.
According to the technical personnel in the industry, the raw material cost of LED filament lamp is composed of LED filament, driving power supply, glass lamp post bracket, glass bulb and standard lamp head hardware. Among these structures, the cost of LED filament is the highest, accounting for 60% of the cost of LED filament lamp. -65%. At present, the basic price of LED filament is within 1 yuan, and a whole lamp generally uses 4 filaments. The ex-factory price of a whole lamp is several times higher than that of an LED incandescent lamp of the same power. Therefore, many consumers are LED filaments. The price of the lights scared.
Fortunately, many companies are constantly finding breakthroughs in technological innovation. In the light of the integration of the leader of DOB, the company is leading the industry in the field of filament lamp driving and constantly innovating intelligent dimming. Through the integration of supply chain and production chain, it provides a comprehensive solution for optoelectronic integration, providing customers with market competitive products, such as cost-effective linear constant current low power LED driver IC-SDS3105, SDS3106; high-order segmentation intelligent dimming IC-SDS3108, SDS3116, SDS3117, etc. In particular, the SDS3105 is actually developed for filament lamps. It is currently the world's leading filament load flexible combination, low power linear constant current drive IC solution, and has obtained global patents.
From the driving point of view, the filament lamp has bottlenecks such as certification, volume and efficiency. This needs to be solved by the IC design company. After the breakthrough of the technology bottleneck, there will be an explosive growth. The market space of the filament lamp is worth looking forward to.
