Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to a railing with light emitting diodes, more particularly, to a railing provided with lighting units having light emitting diodes for lighting and warning purposes. 
   2. Description of the Related Prior Art 
   Conventional Railings have been used widely in public area or at home for the purposes of safety and beautification. However, the railings do not have any lighting system. At nighttime, people may be trapped by the railings, and it exists potential danger to passerby. 
   SUMMARY OF THE INVENTION 
   It is the primary object of the present invention to provide a railing with light emitting diodes, which illuminates light at nighttime to warn people from collision. 
   It is another object of the present invention to provide a railing with light emitting diodes, which can be changed to different colors of light to attract people&#39;s eye and to beautify the place. 
   It is a further object of the present invention to provide a railing with light emitting diodes, which is movable and can be chained to bar unauthorized personal from entering.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   As shown in  FIG. 1 , the present invention comprises a rod  1 , a base unit  2 , a lid  3 , an illuminating device  4  and a controller  5 . 
   The rod  1  is a hollow body and is made of light transparent material. The upper and lower ends of the rod  1  are provided with securing parts  11  and  12 , respectively. The securing parts  11  and  12  are securing holes. The top end of the rod  1  is formed with a pair of slots  13  in opposition to each other. 
   The base unit  2  is coupled to the bottom of the rod  1 . The base unit  2  has a hollow body with a flange  21  protruding from the center top portion. The flange  21  is provided with securing parts  22  corresponding to the securing parts  11  at the bottom end of the rod  1 . The securing parts  22  are securing blocks. 
   The lid  3  is connected to the top end of the rod  1  and is made of light transparent material. The lid  3  is provided with securing parts  31  at the bottom end corresponding to the securing parts  12  at the upper end of the rod  1 . The securing parts  31  are securing blocks. 
   The illuminating device  4  is mounted in the rod  1  and is formed by a number of first and second lighting units  41  and  42 . The first and second lighting units  41  and  42  comprise a number of light emitting diodes  43  lined up in series. The light from the light emitting diodes  43  can be either identical or different color. The second lighting unit  42  is provided with a block  44  on the top. The block  44  is provided with a third lighting unit  45  on the top. The third lighting unit  45  comprises a number of light emitting diodes  43 . The block  44  further comprises a pair of hooks  46  extending from respective sides for connecting purposes. 
   The controller  5  is mounted and secured in the base unit  2 , and comprises a plurality of first electric wires  51  connected to the first, the second and the third lighting units  41 ,  42  and  45 . The controller  5  further comprises a second electric wire  52  connected to an external power supply which can either be a wall outlet of alternating current or a battery of direct current to supply electric power for activating the light emitting diodes  43  of the first, the second and the third lighting units  41 ,  42  and  45 . 
   To assemble the present invention, as shown in  FIGS. 2 and 3 , the controller  5  is secured in the base unit  2  with the first electric wires  51  connecting to the first, the second and the third lighting units  41 ,  42  and  45 . The base unit  2  is inserted to the bottom of the rod  1  with the securing parts  22  engaging with the securing parts  11  of the rod  1  to secure the base unit  2  thereat. The first lighting unit  41  is seated immediately on the flange  21  of the base unit  2 . The block  44  on the second lighting unit  42  is inserted into the slots  13  of the rod  1 , which hangs the second lighting unit  42  to the top position of the rod  1 . The lid  3  is connected to the top of the rod  1  with the securing parts  31  engaging with the securing parts  12  of the rod  1  to secure the lid  3  thereon. 
   To operate the present invention, as shown in  FIG. 3 , the second electric wire  52  is connected to an outside electric power supply. The electric power will be transferred from the second electric wire  52  through the first electric wires  51  to activate the light emitting diodes  43  of the first, the second and the third lighting units  41 ,  42  and  45 . The light illuminated from the first lighting unit  41  penetrates the bottom portion of the rod  1 , while the second lighting unit  42  lights up the top portion of the rod  1 , and the third lighting unit  43  illuminates the lid  3 . The lighting can be seen in the dark easily to prevent passerby from collision. Furthermore, the different colors of the lighting are attractive and can be a decorative design. 
   The rod  1  of the present invention is moveable. Therefore the user may place a number of rods  1  at different occasions and use the hooks  46  of the block  44  to link the rods together to bar unauthorized people from entering.
