Founded in 1990, Shengpu Optoelectronics Co., Ltd. is a modern high-tech management enterprise integrating high-end LED device packaging and LED lighting. At present, it has more than 40 independent patent technologies, and new products and new patents are constantly available in the fields of COB light source and light engine.
“At present, COB light source sales have reached 50% of the total package weight†Ye Bing stressed.
Due to the technical advantages of COB packaging technology for commercial lighting and the significant reduction of the overall cost of lighting applications, the application of LED products is of great significance.
"COB light source surface light source personalized design, high reliability, high light efficiency and high index is very suitable for commercial lighting and industrial lighting needs, the bulb, spotlight market is also gradually introduced, COB light source needs a development process, in some commercial lighting The field, becoming a mainstream light source, is a trend." 
In 2008, the company began to develop COB light source, which was the earliest in China. The first generation technology developed at that time mainly focused on improving luminous efficiency.
In 2015, Ascent Optoelectronics upgraded its COB products. "Smart COB with intelligent control is the focus of our promotion this year." Ye Bing said.
It is understood that this intelligent light source needs to cooperate with the intelligent drive to simulate various kinds of sunlight from morning to night in the lighting effect.
At the same time, with the rapid development of commercial lighting, the market demand for COB light source is more and more demanding. From the 270 degree wide angle illumination to the birth of the ultra-wide angle 330 degree bulb, the COB packaging industry is gradually maturing. However, COB light sources also have problems such as limited angle, loss of light, and uneven light. How to solve these problems has become a problem that every COB packaging company has to think about.
Ye Bing introduced that the personalized COB structure independently developed by Shengpu not only directly replaces the LED filament series in the advantage of 360° wide-angle illumination, but also its light decay, longevity and reliability, which also wins the filament series, truly satisfying customers 360°. The design requirements for wide-angle bulbs. 
Ascending Photoelectricity: COB technology, the only leader
[Text|High-tech LED reporter Luo Shenghua] "The demanding requirements of the market, while giving pressure to COB packaging companies, also promote the industry forward." Ye Bing, manager of Ningbo Shengpu Optoelectronics Marketing Department.
