General study for design the HID ballasts

Abstract

High-intensity discharge (HID) lighting lamp systems are widely used in applications that can provide a high light levels are desired for large areas, such as vehicle headlight, industrial and street lighting. Similar to fluorescent lighting systems, all HID lighting systems require a ballast to operate. Traditionally, magnetic ballast designs were the only choice available for HID lighting systems. Today, high-efficiency electronic HID ballasts are available that provide improved lighting quality and reduce lighting electricity use by 10 to 30 percent.

The purpose of this paper is to identify requirements of the ballast interface from the perspective of the HID lamp. This study will generally brief the starting, run-up, and steady state operation of HID lamps on electronics ballasts.
