Comparison Research of Street Lamps: Characteristic Parameters and Lighting Performance of Light-Emitting Diodes, High Pressure Sodium Lamps and Ceramic Discharge Metal Halide Lamps

Abstract:

As a rapid developing solid state lighting, light-emitting diodes (LEDs) have great potential in application of road lighting, but their performance evaluation in a long term are still lacked. In situ and laboratory measurements were conducted for the purpose of comparing the characteristic parameters and lighting performance of three kinds of street lamps: LEDs, high pressure sodium (HPS) lamps and ceramic discharge metal halide (CDM) lamps. The results of laboratory measurements in 2000 hours show the three kinds of lamps have almost the same initial luminaire efficacy, which lead to the average road illuminance is proportion to the lamp power. The results of road illuminance distribution measurements in 3000 hours show LEDs have better color rendering index, longitudinal uniformity of illuminance, and maintenance of road illuminance than HPS and CDM lamps.
