Also LED light source driving scheme switching mode power supply, although the circuit with high energy conversion efficiency advantage color led module, but in fact switching power components must be used with magnetic energy transfer, which would result in switching mode power supply drive circuit generates a larger volume line relatively complex issues, while discrete components required for switching power more not suitable for module design into LED lighting applications, the use of the driving circuit switched it will result in new restrictions on the design of lighting applications, such as the end product thumbnail design is not easy, or product design complexity is high and so on. 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. LED modular lighting --LED new trend of development is a basic human need, but also represents the level of illumination of economic activity. In recent years, due to global economic growth, continued urbanization, the expansion of non-urban power grid construction and other factors, led to the general increase in the construction of buildings and manufacturing that have made the lighting needs of the rapidly growing consumption of energy has continued to grow. LED as a new light source procurement led modules, are increasingly being integrated into people's lives which led module accessories, it is inseparable from the development of the demand for lighting. Compared to traditional light sources (such as fluorescent and incandescent), LED at close to the theoretical conversion efficiency than conventional light source efficiency 5-20 times higher. Even at this stage of mass production light effects, its level is between 2-15 times, combined with the advantages of its directivity, this gap will be even greater. Due to changes in light principle, the life will be much higher than traditional light sources. Further, since the LED also has no harm to health and the environment and a series of advantages, it has been recognized as the most appropriate at this stage is the next generation light source. However, LED lighting has not been widely promoted, not every household led module, the main reason is the high price of LED lighting, how to reduce the price of LED lighting, markets, and experience tells us --- LED Modular.
