The goal of this project is to evaluate the potential of electronic ballasts and related controls for HID lighting systems to improve the efficiency of current technology.
The specific objectives of this project are to:
- Test, analyze and determine the potential of electronic ballasts for HID lighting systems in cooperation with manufacturers as an emerging energy efficient technology to reduce lighting loads in commercial, industrial and municipal applications.
- Identify control strategies to further improve the energy efficiency of these systems with a municipal partner.
- Provide appropriate recommendations for incorporating these technologies into current state codes and regulations.
Approach
These technologies promise to improve the operating efficiency of HID lighting systems through improved performance in both the ballast and lamp operation, and through control of the light output. Reducing light output, and consequently energy use, to suit the application optimizes the use of electrical energy by end users, and improves the reliability of the electric supply by reducing peak load demands. This project also supports current research activities in daylighting by determining energy and performance characteristics of technologies that reduce the electric lighting-load necessary to supplement lighting from these daylight sources.
Electrical and photometric characteristics of the lamp, ballast and lighting systems will be tested, and the results will be compared to the current technology of magnetic ballasted systems. The evaluation will determine the performance improvements for each component of the system. ANSI standards will be followed in performing these tests.
