When Will Full Spectrum Technology Come?

- Jul 18, 2019-

"The lamp is very good. It is much better than the metal halide lamp that I bought before. It will be bought back.", "I was introduced by a friend to buy a full-spectrum fill light. I heard that people who used it feel good."


In an online store that sells full-spectrum plant fill light on a well-known e-commerce platform, there are many buyers who have similar evaluations above. Looking at other platforms and stores of the same type, there are many such comments. The monthly sales of these stores for full-spectrum products are as low as four or five hundred, and as many as three or four thousand. Most of the buyers are plant lovers of meat and other plants, and the choice of a full-spectrum fill light to maintain the color of the plant, to prevent the length, has become a topic of daily conversation in the forum.


In the past two years, people have a deeper understanding of light, and on the basis of light, they have developed a healthy and comfortable concept. The full spectrum is rapidly becoming popular due to its near-sunlight characteristics. A large number of LED companies are rushing to layout. In plants and some high-end indoor fields, the full spectrum is rapidly infiltrating.


"In the future, the full spectrum will certainly become one of the mainstream trends." Several packaging factories in this layout are unanimously determined. It is obvious to all that outside these two areas, the full spectrum is just “spotting water”. For the overall market, it is still in the incubation period, and there are still some obstacles to going out completely.


Expansion problem


Now, the concept of full spectrum is stimulating the nerves of LED companies at home and abroad. Not only Seoul, Samsung, Osram and other international giants have targeted this technology, and have invested heavily in research and development. Domestic mainstream packaging companies such as Guoxing Optoelectronics, Hongli Zhihui, and Jingke Electronics have also launched full-spectrum related products;昊 Optoelectronics, Heidico Optoelectronics, Juhong Optoelectronics, Xuyu Optoelectronics, etc. are all undergoing continuous technological changes.


Undoubtedly, the full spectrum has indeed increased the bargaining chip for LED companies, which has greatly enhanced the company's popularity. “Our full spectrum products have attracted many customers. The sales volume in the first half of this year has increased significantly compared with the same period of last year,” said Sun Zhijiang, chairman of Heidico. Similarly, companies such as Juhong Optoelectronics are well known for their full spectrum and solar spectrum products.


However, according to industry insiders, the full spectrum is currently mainly used in plants and health, but the overall terminal market share is still small. According to industry research institute data, the penetration rate of the full spectrum in the LED market is less than 2% in 2016. Although it has developed rapidly in the past two years, the growth is still not high. According to Gaogong LED observation, the downstream mainstream manufacturers such as Opp, NVC, and Debon are still dominated by ordinary and intelligent products.


"The full spectrum wants to be fully popular, and there are still many barriers to cross." Juhong Xie Xilong said frankly. As he said, the full spectrum is facing difficulties in terms of cost and light efficiency. “First of all, the cost of the product is higher than that of the ordinary product; in addition, the full spectrum pays attention to the color rendering index, and this will be contrary to the light effect, and the power is difficult to increase. It is indicated that if it is raised from 80 to 90, it will sacrifice 15% of the light effect. To achieve 97, we must sacrifice 10% of the light effect. To achieve the kind of sunlight, we need to lose 30%-50% of the light effect." Sun Zhijiang concluded.


More importantly, the concept of full spectrum has not penetrated deeply into the end consumer group. The current definition of the full spectrum is too broad, and some companies do not hesitate to promote market share. According to the person in charge mentioned above, the full spectrum is focused on complementing the missing light components near the 480 nm band between blue and green light. To be certified as a full-spectrum product, at least fill this short board.

To further popularize, we must first solve these problems. In the eyes of Wu Changqing, the director of Starlight's business, the cost is not enough to pose a threat to the development of the full spectrum. "For Chinese companies, the cost has not always been a big problem. The full spectrum is bound to develop. After the amount, the limit will be automatically hidden." Wu Changqing said
