The invention discloses a solar reflective glass road stud light with a long afterglow luminescent material. The solar reflective glass road stud with the long afterglow luminescent material comprises a glass body (1), a long afterglow luminescent material (2), an LED light source (3), an electric power storage element (4), a solar photovoltaic device (5), a control circuit board (6), a reflective layer (7), a retroreflective layer (8), an encapsulating glue (9) and a base housing (10), and is a solar reflective glass road stud light which changes an optical structure of an existing glass road stud, and combines a long afterglow material. The control circuit board (6) provides power for the LED light source (3) intermittently according to a certain duty cycle or a cycle. A long afterglow energy storage luminescent characteristic is utilized, and the vibrating depth of a strobe is reduced; power consumption of the electric power storage element (4) is reduced by shortening the duty cycle or prolonging the cycle. Based on the principle, an all-weather solar reflective glass road stud which has a higher manufacturing function and is greener and safer can be designed, and not only is the original function improved, but also has an effect of an auxiliary lighting light played on the condition of not increasing power consumption, so that the application range of the road stud is drastically widened.
