1. Fields of the invention
The present invention relates to a movable multi-directional light
stand, especially to an adjustable and retractable light stand that can
rotate in a horizontal plane so as to light in different directions.
2. Descriptions of Related Art
Generally, while camping or working outdoors at night, an
illumination device is used for lighting. Thus there is a plurality of
outdoor illumination device with different designs available now. For
example, a fixed floor light is one of them. Such light is inconvenient
because it is unable to adjust the height of the light. Thus insufficient
light is available or users need to adjust surrounding elements in use.
This is extremely inconvenient and annoying for users.
In order to overcome above shortcomings, a foldable light stand is
provided. The light stand is composed of a support base, a top support
rod, a hollow middle support rod and a light rod disposed on the top

support rod. The support base includes three support feet, a connection
seat, a central support rod and a movable fastening sleeve. The three
support feet are pivoted to the connection seat and the central support
rod is assembled with a central hole of the connection seat. The hollow
middle support rod is inserted into the central support rod. The central
support rod and the middle support rod are assembled and disassembled
with each other by a fastening nut. The top support rod is connected with
the middle support rod and is able to be received in the middle support
rod. The light rod is connected with the top support rod. The
disadvantage of above design is in that the light rod is unable to rotate an
angle in a plane vertically so that the height of the light is unable to be
adjusted. Moreover, the light rod is unable to fold and this is
inconvenient for storage.
Thus there is a need to provide a light stand without disadvantages
mentioned above while with better lighting effect and higher practice
value.
