Abstract:

Early failures of high-pressure sodium (HPS) lamps at a number of roadway lighting installation across the nation cannot be attributed to poor installation or maintenance procedures, but rather to an environment in which luminaire vibration precipitates lamp failure. This paper summarizes the vibration environment found at five sites in the Houston, Texas area. Because the vibration environment proved unexpectedly severe, designers of HPS lamps are challenged by a dynamic environment where g levels commonly exceed 1g, often approaching 4g, sometimes approaching 10g. The severity of this environment is a strong function of luminaire location and local traffic patterns.
