Improved electricity efficiency in constant current module LED household lights

 

We know that all LED constant current power supply, but a lot of street lights manufacturer most come looking for a suitable constant current module LED household lights has been designed. Does not know that this design method will have problems, at least makes this design is not the best. May also want to re-design of the LED household lights module.

 

Often receive customer telephone inquiries, and your constant current driver module is able to bring much power? This problem is that it is impossible to answer. Because of the constant current module with how much power is related to many factors. From the constant current module itself, which is, of course, the current drive capability of the driver chips and cooling requirements and heat dissipation conditions. Yet even these have been finalized, for example, has been selected SLM2842 This is a constant current module, then his ability to drive seems to be completely sure! It is not true! Although it limits the drive capability can know, such as its maximum switching current, the maximum input current, the maximum input voltage and maximum output voltage. However, a constant current drive power modules In addition to its cooling capacity, the most important and its working efficiency. While the efficiency of its work and a lot of external factors, especially the user to usage. So when the design or selection of the LED household lights module is necessary to consider the requirements and characteristics of the constant current source.

 

All the power of the led high bay lamp are almost on the market with built-in. The so-called built-in power on the tube inside. The biggest advantage of this built-in can be made to replace the existing fluorescent tubes directly, without having to make any changes to the original circuit. Therefore, the shape of the built-in power usually do grow bar in order to go into the semi-circular tube.
