Umbrella structure with lighting device

Abstract

An umbrella structure with lighting device comprising a hollow shaft, a plurality of radial arranged stretchers mounted to the hollow shaft, a layer of fabric covered onto the stretchers, a light-emission device mounted at the tip of the hollow shaft, a handle connected at the bottom end of the hollow shaft, and a power supply device mounted with the handle, characterized in that the light-emission device comprises a light transmissive tube cover screwed at the tip of the hollow shaft, a light-emission body mounted within the tube cover, a fluorescent plate positioned between the light-emission body and the tube cover, and a stopper mounted at the top cover of the tube cover, the light emission body is lighted to flicker and the intensity of the emitted light is increased as a result of reflection and refraction by fluorescent body positioned within the fluorescent plate, the fluorescent light is emitted through the transparent tube cover to provide an alarming effect in the night.

I claim:  
     
         1 . An umbrella structure with lighting device comprising a hollow shaft, a plurality of radial arranged stretchers mounted to the hollow shaft, a layer of waterproof fabric covered onto the stretchers, a light-emission device mounted at the tip of the hollow shaft, a handle connected at the bottom end of the hollow shaft, and a power supply device mounted within the handle, characterized in that the light-emission device comprises a light transmissive tube cover screwed at the top of the hollow shaft, a light-emission body mounted within the tube cover, a fluorescent plate positioned between the light-emission body and the tube cover, and a stopper mounted at the top cover of the tube cover, the light emission body is lighted to flicker and the intensity of the emitted light is increased as a result of reflection and refraction by fluorescent body positioned within the fluorescent plate, the fluorescent light is emitted through the transparent tube cover to provide an alarming effect in the night.  
     
     
         2 . An umbrella structure with lighting device as set forth in  claim 1 , wherein the inner wall of the light-transmissive tube cover is provided with zigzag threads so that bright refracted effect of light is obtained.  
     
     
         3 . An umbrella structure with lighting device as set forth in  claim 1 , wherein the bottom end of the tube cover is provided with a screw hole and the top end of the hollow shaft is mounted with a screw seat having a screw rod to combine with the screw hole so that the tube cover is secured to the screw seat.  
     
     
         4 . An umbrella structure with lighting device as set forth in  claim 1 , wherein the surface of the fluorescent plate is a smooth surface, and the other surface is provided with a plurality of conic shaped bodies to enhance the effect of refractions and reflections.
