Bean sail: current status and application of phosphor research

[High-tech LED reporter Zhu Chunwei] On November 26th, in the third session of the CTO conference held in conjunction with the 2013 Gaogong LED Lighting Exhibition, the title of the photovoltaics was held: the packaged devices, equipment and materials II were held in Hall 5, Guangzhou Poly World Trade Center. The meeting was hosted by Dr. Jin Peng, a professor at Peking University Shenzhen Graduate School.

Thanks to the surge in demand for LED backlights and the rapid start-up of the terminal lighting market, orders for domestic LED packaging manufacturers have grown rapidly in the first half of this year. The phosphor market, one of the main raw materials, has been driven by this positive trend.

The theme of the speech by Hilde Chairman Bean Fan is “The Status of LED Phosphor Research and the Application of New Phosphors in Lighting Field”, which are carried out in three aspects: 1. Four challenges facing LED general lighting and phosphor lifting Scheme; 2. Selection criteria for LED phosphors; 3. Common synthetic methods for LED phosphors.

The rapid changes in technology and the wide application of products, seeking more economical costs, the Chinese LED market will continue to grow rapidly in the future.

In addition, the domestic market demand for LED red powder is increasing day by day, especially in the high market demand. According to statistics from the High-Tech LED Industry Research Institute (GLII), the total output value of the red powder market in 2012 has exceeded 34 million yuan, with a compound annual growth rate of 70%.

Hilde has launched a red powder high-definition program, namely low-wavelength red powder + high-bright yellow-green powder. Under the same conditions, not only can increase the brightness, but also reduce the amount of red powder used.

Dou Fan believes that LED phosphor companies must break through the current "internal and external troubles" dilemma, only to grasp the most critical competitiveness - talent and management, and continuously improve technological innovation and create differentiated products.
