LED industry as a new material and energy-saving environmental protection industry representatives, is an important part of the seven strategic emerging industries. National support for energy-saving environmental protection industry for the LED lighting industry has provided the impetus to development. At the same time, with the continuous improvement of technology and maturity, LED lighting costs have dropped for the LED lighting market has created opportunities for development. In recent years, the high-pressure LED has sprung up everywhere and has become a new force in the lighting market. This article begins with an overview of the current trends in the lighting industry, highlighting the benefits of high-voltage LEDs such as reducing power dissipation, increasing AC-DC conversion efficiency, simplifying drive circuits and improving drive life. Next, we selected the 4550 series and 5630 series of SMC, analyzed and compared the electric characteristics of high voltage and low voltage LEDs in the same series of products, and finally described the future development of high voltage LEDs.
