2. Development of Fluorescent Ceramic LED

2.1 Background The development of fluorescent ceramic LED can be traced back to the 1990s. At that time, with the rapid development of semiconductor technology, LED as a new light source began to emerge. However, due to the limitations of traditional packaging materials, the luminous efficiency and thermal conductivity of LED were not ideal. In order to solve this problem, researchers began to explore new packaging materials. 2.2 Research Progress In the 2000s, ceramic materials with high thermal conductivity and high transparency were gradually applied to LED packaging. In 2006, a research team in Japan successfully developed a fluorescent ceramic LED with high luminous efficiency. This breakthrough has promoted the rapid development of fluorescent ceramic LED. 2.3 Current Status At present, fluorescent ceramic LED technology has matured and has been widely used in various fields. In terms of market scale, the global fluorescent ceramic LED market has maintained a steady growth trend in recent years. According to relevant data, the global fluorescent ceramic LED market size is expected to exceed 10 billion US dollars by 2025.

3. Advantages of Fluorescent Ceramic LED

3.1 High Luminous Efficiency Compared with traditional LED, fluorescent ceramic LED has higher luminous efficiency. The luminous efficiency of ceramic LED can reach 150-200 lm/W, which is 20-30% higher than that of traditional LED. This high luminous efficiency can reduce the power consumption of lighting equipment and achieve energy saving and emission reduction. 3.2 Excellent Thermal Conductivity Ceramic materials have excellent thermal conductivity, which can effectively dissipate heat generated by LED. This not only improves the service life of LED, but also ensures the stable performance of lighting equipment in high-temperature environments. 3.3 Long Service Life Fluorescent ceramic LED has a long service life, which can reach 50,000 hours or even longer. This is mainly due to the excellent stability and durability of ceramic materials. 3.4 Stable Performance The performance of fluorescent ceramic LED is stable and reliable. It has good resistance to temperature, humidity, and shock, which can meet the needs of various application scenarios.
