Structure of lightening umbrella

Abstract

A structure of a lightening umbrella having a plurality of lamp strings fixedly provided beneath the ribs and stretchers thereof, the conductors of the lamp strings are extended into the shaft of the umbrella through a top fixed collar of the umbrella to connect with an electric control circuit provided in the umbrella, the control circuit is further provided at the middle position of the shaft with a lamp-controlling switch and an indicating light, conductors from the control circuit are connected to a power supply on the bottom of the shaft to obtain the required power. Thereby, the lamp strings can have various lightening modes by selection and controlling with the switch, and effects of illumination and decoration can be obtained. By virtue that the electric lines are provided in the shaft, they do not affect the activity of the runner. Besides, the lamp-controlling switch can do remote control with a remote controller.

What is claimed is  
     
         1 . A structure of a lightening umbrella comprising: 
 ribs and stretchers having lamp strings therebeneath, a hollow shaft, a top fixed collar, an electric control circuit and a power supply, said structure is characterized by:    conductors of said lamp strings are extended into said hollow shaft through said top fixed collar;    said electric control circuit is provided in said shaft, said control circuit is further provided at the middle position of said shaft with a lamp-controlling switch and an indicating light;    conductors from said control circuit are connected to said power supply on the bottom of said shaft to obtain the required power;    thereby, said lamp strings can have various lightening modes by selection and controlling with said lamp-controlling switch.    
     
     
         2 . A structure of a lightening umbrella as in  claim 1 , wherein: 
 said electric control circuit is composed of a plurality of resistors, capacitors, diodes, transistors, a Zener diode, an oscillator and a single chip.    
     
     
         3 . A structure of a lightening umbrella as in  claim 1 , wherein: 
 said hollow shaft is comprised of a lower sleeve, a lower positioning sleeve, an upper sleeve, an upper positioning sleeve, an upper fixed collar and a finishing top cap.    
     
     
         4 . A structure of a lightening umbrella as in  claim 3 , wherein: 
 said upper sleeve is provided thereabove equidistantly arranged with a plurality of pin holes for insertion of a latching pin for positioning of a lower runner.    
     
     
         5 . A structure of a lightening umbrella as in  claim 3 , wherein: 
 said upper fixed collar is provided centrally with a longitudinal fitting-over hole, and also is provided horizontally at the positions connected to said ribs with a plurality of through holes communicating with one another; said through holes also communicate with said longitudinal fitting-over hole.    
     
     
         6 . A structure of a lightening umbrella as in  claim 2 , wherein: 
 said control circuit is added with a set of radio emitter and a radio receiver.    
     
     
         7 . A structure of a lightening umbrella as in  claim 1 , wherein: 
 said lamp strings are parallelly electrically connected with one another.    
     
     
         8 . A structure of a lightening umbrella as in  claim 1 , wherein: 
 said power supply is an AC/DC circuit connecting with a power supply plug added with a transformer.    
     
     
         9 . A structure of a lightening umbrella as in  claim 8 , wherein: 
 said AC/DC circuit is a simple bridge-rectifier circuit.    
     
     
         10 . A structure of a lightening umbrella as in  claim 1 , wherein: 
 said power supply provided on the bottom of said shaft of said umbrella is a dry battery providing a DC power source.
