Induction Lighting can be used anywhere you would use a comparable fixture. Some of induction’s inherit benefits make it ideally suited for various applications such as difficult to access areas, parking garages, street lighting, warehouses, high ceilings, parking garages, and warehouses.
How it Works: Electromagnetic transformers consisting of ferrite rings with metal coils, create an electromagnetic field around a gas-filled glass tube, using a high frequency that is generated by an electronic ballast. The discharge path, induced by the coils, forms a closed loop causing acceleration of free electrons, which collide with mercury atoms and excite the electrons. As the excited electrons from these atoms fall back from this higher energy state to a lower stable level, they emit ultraviolet radiation. The UV radiation created is converted to visible light as it passes through a phosphor coating on the surface of the tube. The shape of the induction lamp maximizes the efficiency of the fields that are generated.
The ballast generates the high frequency current that drives the inductively coupled discharge. The ballast contains an integrated circuit (IC) chip, which controls the operating frequency and allows the electrode-less fluorescent lamp to work properly with a ballast power factor of up to .99 for lower power consumption. This control feature is especially beneficial where fluctuations in the power supply are more than 10% of rated voltage. The ballast also meets EMC requirements, and the circuit board is designed for dust, humidity, and corrosion.
