数字式LED驱动电源嵌入式设计研究

Embedded Design Study of Digital LED Driver Power Supply

随着全球能源危机问题逐渐突显,低碳环保开始被人们重点重视,照明作为能源消耗的一大方面也备受社会人士的关注。LED作为新时代下的固态光源,具有环保、节能、寿命长、效率高和易控制等优点,也被认为是如今最具发展前景的技术。由于数字式LED驱动电源设计在动态光调节下不够全面和完善,导致对LED的调节无法达到预期的效果。设计嵌入式系统下LED驱动电源,可有效提高驱动电源的功能,测试结果表明,所设计的数字式LED驱动电源具有转换效率高、驱动性能强等优势。

With the global energy crisis, low-carbon environment protection has been emphasized, and lighting as a major aspect of energy consumption has also attracted the attention of the society.LED as a solid-state light source in the new era, with the advantages of environmental protection, energy saving, long life, high efficiency and easy control, is also considered as the most promising technology nowadays. As the digital LED drive power supply design is not comprehensive and perfect under the dynamic light regulation, it leads to the regulation of LEDs cannot achieve the expected effect. The design of LED driving power supply under embedded system can effectively improve the function of driving power supply, and the test results show that the designed digital LED driving power supply has the advantages of high conversion efficiency and strong driving performance.
