Graphene, which has the reputation of “king of materials”, has been predicted by scientists to change the entire 21st century. For LED lighting, the chemical and physical stability of graphene, excellent electrical conductivity and directional heat dissipation performance can increase the thermal conductivity of LEDs and reduce costs.

Graphene enters the commercial stage?

In recent years, graphene has been used in the field of LED lighting. The Graphene Institute of the University of Manchester has developed a new graphene bulb based on LED technology, which has a longer life span and lower price. A team of professors from the Department of Micro-Nano Electronics of Tsinghua University has developed a color-codeable graphene LED that covers almost the visible spectrum. Beijing Professor Qu Liangxue and his team at the University of Science and Technology successfully lit LED bulbs using electricity generated by water and graphene...

Nonetheless, any new material or technology that goes out of the lab faces a common problem, how to reduce the cost of technology and commercialize it while ensuring high quality and consistent quality.

In August last year, graphene lighting made substantial progress. Shandong Jingtaixing Optoelectronics Technology Co., Ltd. (hereinafter referred to as “Jingtaixing”) signed a contract with British Graphene Lighting Co., Ltd., and its merged new company is the first company in the world to apply graphene technology to LED lighting. This move will push the development of graphene in the field of lighting to the stage of commercialization.

A LED lighting company with less than three years of establishment has won the favor of foreign innovative companies. Is the application of graphene in the field of lighting as reported? What technical obstacles exist?... with many questions, reporter Recently, Dr. Ma Wenbo, the technical leader of Jing Taixing, was interviewed.

Market development focus - graphene filament lamp

At present, Jingtaixing mainly applies graphene materials to filament lamps. According to Dr. Ma Wenbo, there have been some technical obstacles in its application in filament lamps, such as the preparation of graphene paste, the coating process of graphene paste, and the packaging process of curved graphene filaments. The research, these technical obstacles have been overcome one by one."

With the solution of the technical bottleneck, graphene lighting has officially entered the stage of large-scale industrial application, and the market has shown great interest in this differentiated graphene curved filament lamp product. A craze began to carry out comprehensive and extensive promotion in the market to seize market opportunities."

Graphene lighting will be the core of Jingtaixing's future development market. The filament lamp is the key product of Jingtaixing. According to Dr. Ma Wenbo, the current production capacity of Jingtaixing is 3 million per month, which is expected in 2017. In the first half of the year, the resource allocation of 5 million monthly capacity will be completed. "With the development of the North American market this year, I believe that its market application will usher in a new round of growth."

It is understood that Jingtaixing covers an area of ​​500 acres and now has 50 packaging production lines, 10 EMC bracket production lines, 10 LED filament lamp production lines, and 5 LED SMD production lines. The level manufacturing plant is also supporting the graphene technology to fully enter the field of LED lighting for mass production.

Graphene will cause another round of innovation in lighting technology

The LED filament lamp market has become more and more competitive after the international giants have successively added codes. Dr. Ma Wenbo has absolute confidence in his products. “Jingtaixing Filament Lamp is a product series integrated in vertical industry chain. It is in the hands of all processes and manufacturing processes such as filament packaging, power IC design and packaging and testing, power supply manufacturing, whole lamp sealing and assembly. In order to effectively control product cost, quality and delivery time, Jingtaixing has a clear competitive advantage for competitors who only know one or both of the filament lamp manufacturing processes.

Just as Yuan Xincheng, chairman of Jingtaixing, has publicly stated that Jingtaixing filament lamp has excellent cost competitiveness. “To produce the same 8W, 20W or 50W products, our average gross profit margin is 15% higher than competitors. ."

In addition, after the merger, Jingtaixing has 12 world-leading patents for British graphene lighting, and its products are sold all over the world.

Even though in the past two years, the former filament lamps in China have been closed down, but this has not affected the market of Jingtaixing’s deep-light LED filament lamp, but it has enhanced the risk awareness of Jingtaixing and the continuous innovation of products. pursue.

For the future planning, Dr. Ma Wenbo said that Jingtaixing's product line involves the entire LED industry chain in the upper, middle and lower reaches, and will continue this product strategy in the future, and become the LED “Almighty King”.

In 2017, Jingtaixing will still be based on international OEMs, but will consciously promote its own brands in the domestic market. He revealed that in the future, in terms of products, Jingtaixing will gradually improve the European regulations, American standard dimming and non-dimming series products, and launch flexible filament lamps series; in the market, it will continue to maintain the European market channels, and this year will focus To explore the channels of the North American market; in terms of domestic channels, the focus of development will be on the lighting market in Zhongshan, Changzhou and Linyi, and slowly penetrate the national market.

Finally, Dr. Ma Wenbo said that graphene has broad development prospects in the field of lighting. Low cost and excellent thermal radiation characteristics make graphene the first field to be scaled up in the field of semiconductor lighting and heat dissipation. It will also be lighting. Technology brings an innovation.
