Tcc Electrodeless Discharge Lamps use the plasma, and magnetic material, free electrons (e-) in EDL are accelerated by microwave field.-The gas inside the lamp is excited by the magnetic field and turned into plasma. -When the excited atoms of plasma return to the ground state, they radiate UV/VIS light, which is converted into visible light by phosphor coating on inner glass surface in the same manner of fluorescent lamps.USE:-Indoor and outdoor lighting-Locations where are difficult to access with , such as freeways , tunnels , bridges etc. -Emergency lighting requiring instant (re) strike , such as airport. -Harzadous areas
