China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

EC magnetic ballast  for fluorescent lamps, compact fluorescent lamps and the luminaire insets for compact fluorescent lamps UEC are robust and extremely costeffective solutions with long lives. The wide range of low-loss ballast in energy efficiency classes B2 and B1 from James lighting covers all the relevant applications and ensures that the lamps are operated as specified.
 

There are always energy losses fluorescent ballast. These energy losses will generate heat and cause thermal problems. The losses in ballasts are from the following sources:

1. Hysterisis loss from the sweeping of flux from positive to negative and the area enclosed by the loop is the loss. Hysterisis loss is due to the materials intrinsic properties due to the energy used to align and re-align the magnetic domains. You can lower this loss by using a more expansive materials such as TDK PC 44, for example.
2. Eddy current loss from the circulating currents within the magnetic materials due to differential in flux voltage inside the cores itself. This loss is high dependent upon the thickness of the walls of the cores. The higher the switching frequency, the higher will be this eddy current loss.
3. Copper or winding loss. This is also dependent on the wire size, switching frequency, etc. Skin effect and proximity effect will contribute to this loss.
