This paper discusses trends in HID street lights, based on six keywords: new light source, light-induced problems, energy saving,theftproofing, safety and durability.In particular, the advent of the ceramic metal halide lamp as a new light source has enabled the designof street lights as high-quality outdoor luminaires.This has provided more latitude in designing street lights.Also, luminairemanufacturers have introduced energy-saving street lights that are excellent in terms of luminous intensity distribution, and therefore cancontribute to reduce light-induced problems.
