Fourth Generation Light Sources. NASA Astrophysics Data System (ADS) Winick, Herman. 1997-05-01. Concepts and designs are now being developed at laboratories around the world for light sources with performance levels that exceed present sources, including the very powerful and successful third generation synchrotron radiation sources that have come on line in the past few years.

Solar Road Markers (SRM) are exceptionally effective in road safety enhancement, far surpassing passive markings, such as painted lines and reflectors. Roadways with distressed traffic environments, over‐illuminated lighting, dark areas, undefined borders, and hazardous conditions of any kind can

The reflective pavement marker, which is maintenance-free, is a lighting device powered by solar energy and is used in road construction to delineate the road for motorists. The reflective pavement marker of aluminum shell has strong pressure resistance, and the pressure resistance of NK-RS-A6 is over 20 tons, so it is always installed in the.
