Retractable bollard light

Abstract

A retractable bollard light has a shell set and a main body. The shell set is configured to be set underground. The shell set includes an outer shell, an inner shell, and a top cover. The inner shell is in the outer shell, and the top cover is mounted on the outer shell and the inner shell. The top cover has a top opening formed through a top surface and a bottom surface. The main body has a moving assembly, a light source assembly, and a power module. The moving assembly is in the inner shell and is movable with respect to the inner shell. The light source assembly moves with the moving assembly out of the inner shell through the top opening. The power module is electrically connected to the moving assembly and the light source assembly. The retractable bollard light may be retracted when not in use.

 a housing connected to the moving assembly;   a driving module mounted in the housing;   an illumination unit pivotably mounted in the housing; and   a link connecting with the driving module and the illumination unit, thereby the driving module capable of driving the illumination unit to pivot.   
     
     
         9 . The retractable bollard light as claimed in  claim 7 , wherein:
 the light source assembly has a limit block securely mounted in the housing, and thereby a moving range of the link is limited.   
     
     
         10 . The retractable bollard light as claimed in  claim 8 , wherein:
 the light source assembly has a limit block securely mounted in the housing, and thereby a moving range of the link is limited.   
     
     
         11 . The retractable bollard light as claimed in  claim 7 , wherein:
 the housing has an upper surface facing upward and being level with the top surface of the top cover.   
     
     
         12 . The retractable bollard light as claimed in  claim 10 , wherein:
