Whether it is high-power or low-power LED lighting applications, it is generally composed of power supply, LED driver , LED, lens and substrate. The key component is LED driver , which must provide a constant current output to ensure LED emission. The light will not be flickering and LED color shifting will not occur. It generally accepts 24V-48V DC voltage input, but there are also some advanced LED drivers that can directly accept 220V mains AC input. Most customers require high-performance LED drivers to meet upcoming LED lighting specifications such as "PF Value" 0.9" and "+85 Efficiency." The main design challenges for LED lighting applications include the following: heat dissipation, high efficiency, low cost, dimming without flicker, wide dimming, reliability, safety, and elimination of color cast. These challenges need to be addressed by a combination of appropriate power system topology, drive circuit topology, and mechanical design. Liang Houquan, director of technology marketing for Diodes Asia Pacific, said: "The biggest technical challenge for designers will be high efficiency requirements, optical design, thermal management and improved reliability of certain applications, such as high-brightness LED street lights. We now offer A range of LED lighting solutions cover applications from 0.1W to 250W." Liang Houquan, Director of Technology Marketing, Diodes Asia Pacific “In the application of LED lighting systems, in addition to selecting the right LED products , a complete LED lighting design also includes optical design, thermal design, product design and electrical drive design. Since LED is a low voltage device, it converts high voltage AC power. The low-voltage constant-current drive used for LEDs will face many challenges.†Zheng Zongqian, senior application manager of ON Semiconductor China, pointed out: “Further, in order to ensure the advantages of LED lighting, LED electrical drives must be reliable, efficient, and safe. And low cost. Therefore, for different LED lighting applications, the first choice is to choose the correct drive circuit topology.†ON Semiconductor now offers all LED lighting solutions from 1W to 500W. Zheng Zongqian, Senior Application Manager, ON Semiconductor China In order to quickly push the LED lighting market off, National Semiconductor Corporation (NSC) recently targeted a very large incandescent lamp to directly replace the market, using LED lights to directly replace incandescent lamps in existing home or other application markets, and launched A direct mains input LED driver chip LM3445 for this market.
