Packing the LED into 12V can completely solve the problems of difficult power supply design, short life and high price. Using Distributed Constant Current to design the most stable, cost-optimized, and most economical product architecture, combined with a 12V package, it will dominate the world's power supply. Breaking the power supply design to adapt to the LED specification pattern, in turn, the LED package adapts to the nominal value of the power supply voltage. We believe that the previous companies in the design of LED packaging, mostly consider the LED package itself, combined with the application design considerations, rarely consider which will be the future lighting package form. LED lighting manufacturers are striving to develop power supplies to adapt to LED package forms, too many packaging forms and numerous design concepts, so that our power supply design is impossible. In turn, the LED light source directly adapts to the switching power supply, and everything becomes simple, because the switching power supply has become very standardized and stable after several decades of development and technology precipitation. The main research focus of LED lighting products is on the secondary DC part, distributed constant current architecture technology, and solving the LED packaging technology that adapts to lighting. This is the issue we are focusing on today. 1. 12V LED importance We always think that it is: first constant pressure, then constant current. It is recommended that the voltage nominal value package LED, namely: 12V, 24V, 36V, 48V nominal voltage value, because these voltages are the nominal value of the universal power supply. In development, it was found that as long as the focus packaged 12V LED can be applied to all nominal voltages, the latter voltages are multiples of 12V. The single LED package is 12V, the string 2 design is 24V, the 3 is 36V, and the 4 is 48V. Visible the importance of 12V LED. To make the LED package 12V is not as simple as imagined, the chip is directly connected in series, and the three are less than 10V driving voltage, so the driving power supply is not efficient. A simple 4 series connection exceeds the nominal value of 12V, causing the drive voltage to deviate from the voltage nominal value. There are still some methods, which need to re-cut the LED chip, properly select the appropriate current density, and make the LED package 12V become a reality. 2. Distributed constant current architecture technology The distributed constant current is: an independent constant current source is established at each parallel branch point, thereby managing, maintaining, controlling the branch and the overall line stability. It can be regarded as a complete line structure in use, and the practical application is constant current control distributed in each node of the line and can communicate with each other. Distributed constant current design LED products have very high product stability. At present, LED products claim to have a large gap with the actual service life. In the case of limited accumulation of drive line design technology, the life of the product is estimated to be far from the actual use. Drive line stability directly affects the overall stability of the product, and distributed constant current has a unique advantage. Keeping the branch and the overall current stable, it is also convenient to control the management branch and the overall line work, which is the scope of distributed constant current architecture technology. Driving the LED requires a constant current, but the magnitude of the current depends on the application environment. The intelligent development of LED lighting is the key, and the distributed constant current technology fully reserves the intelligent interface. The biggest feature of the distributed constant current architecture technology is that the AC power supply part continues to use the traditional switching power supply, constant voltage power supply mode. The accumulation of switching power supply technology will create quality conditions for LED power supply design. Although accelerating aging to estimate power supply life is a method, there is still a gap between the long-term practical technology accumulation of traditional switching power supplies! In the current street lamp design, switching constant current modules are used, and low voltage Compared with the differential constant current IC, the switching constant current efficiency, constant current accuracy, EMI, cost, and reliability are not as good as the low dropout linear constant current converter. There is absolutely no need for complex constant current modules. The constant current source placement point is flexible. In all parallel branches, no other branch work is affected by the branch current change. Both want to choose LEDs to get load impedance matching, distributed constant current can be designed to be more perfect, the requirements are not very high and can be dispensed with. In order to improve the stability of the lighting products, the current of each branch and the overall line is kept stable. Distributed constant current technology is a series connection, low dropout linear constant current driver on a node that needs constant current. Low dropout is important and is related to product drive efficiency. There are many kinds of constant current driving, in which low-drop differential linear constant current can realize all LED application design, that is, stable and simple, combined with switching power supply, has a perfect constant current driving architecture. Linear constant current drive efficiency is highest in low dropout environments. The constant current source is placed. At each parallel branch node, it can also be an integral constant current point design. The constant current source serial branch can play a good role in a certain position. Generally, the number of constant current drive channels is difficult to match with the design, and the distributed constant current has a high degree of design flexibility. In the LED lighting circuit design, the AC power supply needs a feedback circuit, with the number of output LED drivers, and the rationality of the driving efficiency. In the distributed constant current driving source, each driving source can directly perform the optocoupler feedback task. Drive the line peripheral 0 device, this is our goal, the peripheral 0 device will not bring the design device parameter error accumulation, the constant current accuracy caused by the accumulation of peripheral device error will rise back to 0. 3. Conclusion Under the wave of rapid development of LED technology, LED will become one of the main lighting sources, unified drive design ideas, clear design ideas. With more optimized design methods and breakthrough architecture development, it has made due contributions to the development of LED lighting technology!
