  • The LED Industry Entering The Era Of Full Spectrum
    Nov 05, 2018

    The full spectrum, called the "net red word" in the LED industry, is not an exaggeration. Since the beginning of this year, domestic packaging companies including Xuyu Optoelectronics, Hongli Zhihui, Guoxing Optoelectronics and Xingguangbao have launched full-spectrum slogans and launched corresponding full-spectrum products.

    In fact, the full spectrum of LED light source research and development has been internationally for many years, but the current technology is limited to the development of visible light in each band to achieve continuous spectrum, improve the color rendering index, but the ultraviolet and infrared parts are difficult to achieve continuous spectrum . The spectrum of each UV and IR LED lamp bead is narrow, limited to a specific band, combined into a continuous spectrum, which is very difficult and costly.

    As a representative of the strength of the domestic packaging field, Xuyu Optoelectronics (Shenzhen) Co., Ltd. (hereinafter referred to as “Xuyu Optoelectronics”) has made important breakthroughs in the technical level through cooperation with Shenzhen Tsinghua University Research Institute in the field of full spectrum research. This time, Xuyu Optoelectronics' “XY-2835 Full Spectrum” product achieved Ra≥98, CRI≥97, Rf≥98, Rg≥100, and R1-R15 values were all greater than 95. It is worth mentioning that this product not only achieves full spectrum, but also has good performance in terms of light efficiency, and its luminous efficiency can reach 90-140 lm/W.

    According to reports, the key to the solution of full-spectrum products in technology development lies in the coupling between LED chips and phosphors and the improvement of light efficiency, especially the further improvement of R12 index and Ra index. At present, the development status of the full spectrum technology in the market is Ra>97, and the R1 to R15 indexes are all greater than 90. It is not mature due to the development of LED cyan phosphor. The conventional full-spectrum technology R12 is difficult to break above 95, even if it breaks above 95 yield. Also very low. Xuyu Optoelectronics' full spectrum research and development has covered single-blue, dual-blue and violet-excited full-spectrum technologies. For different applications, Ra has exceeded 99 and R1-R15 has exceeded 95.

    Moreover, the full-spectrum technology currently on the market generally has the characteristics of high cost, relatively low light efficiency, and poor device stability. The development of XY-2835 full spectrum is firstly mature in technology, and the yield is increased by 30%, which greatly reduces the cost of the product. Secondly, the phosphor used in the product has a great improvement in stability, and the stability of the device is obtained. In the end, the product selected the best chip and phosphor matching solution, using the most advanced technology in packaging materials and packaging technology, and the light efficiency of the product has been greatly improved.

    Just because it breaks through some common defects and shortcomings of other full-spectrum LEDs on the market, Xuyu Optoelectronics' full-spectrum LED light source is well received by customers. “The product spectrum is very similar to sunlight, and it has a significant advantage in indoor applications.” Some customers have commented that “the price of the product has a decisive advantage over the market, and its performance is better than the overall market level.”

    As a high-tech enterprise deeply rooted in the field of LED packaging, Xuyu Optoelectronics has always paid attention to the independent research and development and innovation of its products since its establishment, and has repeatedly undertaken the key scientific and technological plan of the Science and Technology Commission of Shenzhen Science and Technology. More than 50 new patents. Moreover, Xuyu Optoelectronics SMD products are all made of 99.99% pure gold wire and copper brackets. Over the years, they have continued to focus on high-reliability LED packaging, bringing better solutions for a series of applications.

    It is worth mentioning that at the 10th anniversary of the expert LED, Xuyu Optoelectronics will also bring the keynote speech of "LED industry enters the era of full spectrum". At that time, Xuyu will discuss the development trend of the full spectrum technology, current technical difficulties and solutions with many people in the industry. This annual industry event will be held in Shenzhen Venus Royal Hotel on December 13-14, so stay tuned!
