Tianju Optoelectronics has developed a unique single-chip high-power LED light source product worldwide.

Today, LED has become a highly competitive "Red Sea market." A company that has settled in Ningbo for less than a year has developed a unique single-chip high-power LED light source product in the world, which has driven the industry's progress and sustained breakthroughs in driving technology research and development, and effectively improved people's quality of life.

LED light source products commonly found in the market are usually formed by splicing a plurality of lamp beads or chips, and the light-emitting area is large, and the stability is not good. To this end, Cai Yong, a researcher at the Suzhou Institute of Nanotechnology, Chinese Academy of Sciences, puts the focus of technology research and development on a single chip, which can reduce the luminous area and increase the optical power density while improving stability, and can even be customized according to customer needs. After repeatedly verifying the practicality of the technology, Cai Yong founded Ningbo Tianju Optoelectronics Technology Co., Ltd. in 2016 and settled in Cixi High-tech Industrial Park in July 2017.

In Cai Yong's view, the single-chip high-power LED light source product is "thinner, more reliable LED." At the same power, the light-emitting area of ​​the product is reduced by four times compared with the LED chips that are commonly used in the market. The product also features a highly reliable redundancy design, where each component of the chip operates independently, even if the short circuit does not affect the overall operation.

When interfacing with customers, Cai Yong often heard such a question: “Make a fuss” on a positively small chip, can the product's pass rate be guaranteed? Can the heat dissipation problem be properly solved?

In theory, the smaller the chip area, the lower the pass rate. Therefore, the theoretical pass rate of a single-chip product is about one in a million, which is completely unusable. To this end, "Tianju Optoelectronics" refers to the integrated circuit mode to segment and integrate the chips, and the internals are independent and externally connected to each other, ensuring that the product qualification rate of 20 watts exceeds 90%, and the product qualification rate of 50 watts exceeds 80. %. In addition, "Tianju Optoelectronics" has developed a high-heat-dissipation packaging technology that reduces the maximum temperature of the chip from 180 degrees Celsius to 60 degrees Celsius, extending the service life by about 3 times.

Today, "Tianju Optoelectronics" has applied for 8 patents in the United States, the European Union, Japan and China. The power of the product is 10 watts to 1000 watts. It can be used for flashlights, headlights and track lights, as well as for stage lighting. Stadium lighting, special lighting. At present, the company has signed an agreement with an Anhui lamp factory to require more than 3 million chips to be put into production in three years. The first batch of 100,000 chips has been produced and is expected to be launched in the second half of this year. Recently, “Tianju Optoelectronics” also participated in the “Looking for the Most Investing Value Enterprise in Ningbo” activity, and tried to reach a cooperation with the downstream enterprises in Ningbo, which are mainly engaged in the export business of high-end LED lamps.
