Abstract :
Dimming application in high intensity discharge (HID) lamps can affect several lamp parameters such as: lamp life, power factor, color temperature, discharge arc path, among other effects. With the purpose of analyzing the dimming in HID Lamps, a comparative analysis of dimming effects in metal halide and high pressure sodium (HPS) lamps is presented in this paper. With this purpose, several lamps were characterized and electrical models were developed for their simulation in PSpice.
