Abstract

A novelty item in the form of a rod suffused with a fluorescent substance. The substance fluoresces in response to ambient light and the flouresced light is subject to internal reflection within the rob, with the flouresced light being substantial emitted at one or both ends of the rod. The concentration of the light enables a variety of uses, such as a broad range self-illuminating toy wands as a luminescent professional, presentation pointer.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A toy wand comprising: 
 an elongated rod of substantially transparent material, said rod having a length and a cross-sectional width and having a first end and a second end;    a dye suffused substantially throughout said material wherein said length, said width, and said dye are selected such that light energy emitted by said dye in response to incident light energy undergoes substantially total internal reflection within said rod; and    said first end of said rod is adapted to emit light energy.    
     
     
         2 . The toy wand according to  claim 1 , wherein said second end is internally mirrored.  
     
     
         3 . The toy wand according to  claim 1 , wherein said second end comprises a grip.  
     
     
         4 . The toy wand according to  claim 1 , wherein said rod has a substantially right circular cross-section  
     
     
         5 . The toy wand according to  claim 1 , wherein said first end has a substantial conical shape, the exterior surface of which is adapted to emit light energy.  
     
     
         6 . The toy wand according to  claim 1 , wherein said first end has a substantially multi-pointed star shape, said multi-pointed star shape having at least two points, the edges and points of said multi-pointed star shape adapted to emit light energy.  
     
     
         7 . The toy wand according to  claim 1 , wherein said first end comprises a plurality of optical fibers, said optical fibers adapted to emit light energy from the terminal ends of said optical fibers.  
     
     
         8 . The toy wand according to  claim 1 , wherein said second end is adapted to emit light energy.  
     
     
         9 . The toy wand according to  claim 8 , wherein said first end and said second end have a substantially spherical shape, said substantially spherical shapes adapted to emit light energy.  
     
     
         10 . A luminescent pointer comprising: 
 an elongated right circular rod of substantially transparent material, said rod having a first end and a second end;    a dye suffused throughout said transparent material; and    said first end adapted to emit light energy.    
     
     
         11 . The luminescent pointer in  claim 10 , wherein said second end comprises a grip.  
     
     
         12 . The luminescent pointer in  claim 10 , wherein said second end comprises an internally reflective cap.  
     
     
         13 . The luminescent pointer in  claim 10 , wherein said first end has a predetermined shape having external surfaces, said external surfaces adapted to have a significantly reduced capacity for internal reflection of light energy.
