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 led display manufacturers, 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 growth. LED as a new light source, is increasingly being integrated into people's daily lives, 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 Hebei led display, mainly due to the high price of LED lighting, how to reduce the price of LED lighting, markets, and experience tells us --- LED modular. How pairing method modules LED modules in the resistance of the resistance should be configured? I believe the technical aspects of research customers and friends must have mastered the knowledge and skills together to understand. LED light module with general resistance is mainly based on the LED lamp beads with the voltage and current to set. Now lamp beads used mainly piranhas lamp beads 5050 and 3528 SMD LED module and beads. They are basically the same voltage, white, blue, green are 3.0V-3.4V, red and yellow are 1.8V-2.4V. With resistance at the time led screen rental, choose an intermediate value bought voltage lamp beads, lamp beads buy if marked voltage is 3.0-3.2V, select voltage of 3.1V.
