In practical design, SoB design uses smaller driver IC solution that can make the overall layout of the LED light source particles have more flexibility, because the driver IC will not be bulky gear to LED arrangement design can be avoided because Driver IC Barrier practical benefits p16led unit board SoB light type arrangement, in addition to the driver IC volume should be noted, the fact that the size of passive components is focus. Although the use of double-sided PCB material may be concentrated on one side of the light-emitting component material, the drive IC / passive components focused on the other side of the material, but in fact for automated production more simple, fast, cost reduction approach will be used more on one side of the material, so that the process easier, so LED light-emitting component layout on the need to avoid driving IC / passive components unit board, or use a small piece of material designed fabric. Also switching power supply LED light source driving scheme, although the circuit has a high energy conversion efficiency advantages 3.0 unit board, but in fact switching power components must be used with magnetic energy transfer, which causes the drive circuit switched mode power supplies generate a larger volume, line relatively complex problem, discrete components required for switching power while more is not suitable for introducing LED lighting applications modular design p8 unit board with circuit switched drive but will result in new restrictions on the design of lighting applications, such as terminal Product miniature design is not easy, or high product design complexity and other issues. Instead, the implementation of a linear constant current LED light source driving circuit architecture, because no external storage or energy conversion components, can greatly simplify circuit design complexity, but also with small size, low cost, less discrete components, such as design advantages for SoB single circuit board lighting module design. p8 cell plate, the cell plate, Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd.
