Abstract: A pavement marker which can passively reflect incident rays and independently emit light is disclosed. It includes a housing and a unidirectionally reflective/light-penetrative panel (URLPP) covering the housing to form an inner space and having a central hole. A rechargeable battery, a circuit board with LEDs and a generator are received in the inner space. The circuit board and generator electrically connect to the rechargeable battery. The generator has a spindle penetrating the central hole. The propeller is fixed to the spindle. The generator and the propeller constitute a wind generator to charge the rechargeable, outer light projected onto the URLPP will be reflected, and beams emitted by the LEDs will penetrate through the URLPP.

Abstract: A reflective roadstud and manufacture of the same including steps of forming an upper and lower cover from mixture of acrylonitrile butadiene styrene (ABS) and basalt fiber with a mixing ratio of 1:0.05˜0.5 by injection molding. The upper cover and the reflective sheet are combined by ultrasonic welding, and the lower cover is arranged to the upper cover as a finish. The finish is further coated by a nanotech inorganic heat dissipating coating (Sio2, Cao).
