"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-degree illumination. The light source is the closest to the incandescent lamp. The same international standard lamp holder, 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, and the filament lamp replaces the incandescent lamp. Probably the best choice."
The LED filament lamp market is booming, but it is two difficulties in front of Chinese manufacturers, patents and production capacity. According to LEDinside's investigation 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 Ruidison (Ledison). ), as well as 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 LED filament patents in the United States, Europe, China, 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. Lin Linliang, executive general manager of Mulinsen
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 SMD LED 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 SMD LED light source products.†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.
