In the highly competitive LED chip market, there are two trends in the development and application of LED white light chips: one is to pursue the ultimate light effect, with a larger chip area, smaller current drive to obtain higher light efficiency; The other is to pursue high current injection and increase the injection current on the same chip area to reduce the number of chips used and reduce the cost. In response to the above two trends, Maanshan Yuanrong Optoelectronics Technology Co., Ltd. recently launched two highly competitive medium-power white light chips: 23B and 30B.
The 23B chip has a voltage of only 2.8V at 30mA, is packaged into a white light device, has a color temperature of 5000-6000K, a color rendering index of 75 or more, and can achieve a light effect of 160 lm/W or more; while a 30B chip drives at a current of 150 mA, the voltage is 3.1 V or less. The luminous flux is more than 50lm. Even if the current is applied to the 350mA voltage, it is below 3.5V, which has very good volt-ampere characteristics and good light efficiency.
It is understood that the above two products are in the leading position in the same model products. Since the products were put on the market, they have received the attention of customers and won wide acclaim, and orders have continued to increase.
Since it was put into production at the end of 2011, Yuanrong Optoelectronics has undergone a one-year development and has completed the transition from production to mass production. At present, the market share of Yuanrong Optoelectronics LED white light chips ranks among the top three. Adhering to the quality policy of “Scientific Management, Continuous Innovation, Continuously Providing Satisfactory Products and Excellent Service to Customersâ€, and attaching importance to scientific research and development and technological innovation, Yuanrong Optoelectronics is building more products with unique characteristics and serving the society.
