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

magnetic chokes for fluorescent lamps and compact fluorescent lamps and the luminaire inserts for compact fluorescent lamps UEC are robust and extremely cost-effective solutions with long lives. The wide range of low-loss ballasts in energy efficiency classes B2 and B1 from James Lighting covers all the relevant applications and ensures that the lamps are operated as specified.

The choke coil works because it acts as an inductor. When the current passing through changes, as AC currents do, it typically creates a magnetic field in the coil that works against that current. This property, known as inductance, blocks most of the AC current from passing through. As a result, currents that do not change, such as DC currents, can continue through while those that do are blocked by the very magnetic field they created.

When the conductor or wire is wound around a magnetic materials ( ferrite, nanocrystalline, amorphous, iron, steel, MPP, sendust, high flux, mega flux, etc), and current flows through the conductor, a flux is induced on the magnetic materials. This flux is induced by the magnetic field generated by the current carrying conductor. The magnetic material's atomic parts got influenced by the magnetic field and causes them to align in a certain direction.

magnetic chokes for luminaire installation are characterised by minimal energy consumption, compact windings, optimised dimensions and high-quality materials. In temperature sensitive applications, the B1 version offers additional benefits thanks to its lower energy consumption and 15k lower self-heating.
