Ball with lighting device

Abstract

A ball includes an inflatable inner sphere and a receiving tube is located in the inner sphere so that a lighting device is received in the receiving tube. An outer layer is coated to the inner sphere and has a plurality of holes defined therethrough. The lighting device includes a switch unit, a power unit, an activation unit and a lighting unit, wherein the switch unit and the activation unit are electrically connected with the power unit, and the lighting unit is electrically connected with the activation unit so that when the switch unit is activated, the lighting device lights up.

1 . A ball comprising:
 an inflatable inner sphere and a receiving tube received in the inner sphere, an outer layer coated to the inner sphere and having a plurality of holes defined therethrough, and   a lighting device received in the receiving tube and includes a cylindrical case in which a switch unit, a power unit, an activation unit and a lighting unit are received, the switch unit and the activation unit being electrically connected with the power unit, the lighting unit being electrically connected with the activation unit so that when the switch unit is activated, the power unit provides electrical power to the lighting unit, the lighting device lighting up when the activation unit is activated.   
   
   
       2 . The ball as claimed in  claim 1 , wherein a sleeve is located between the receiving tube and the cylindrical case, the sleeve has two L-shaped slots, the cylindrical case includes two protrusions which are movably engaged with the L-shaped slots so as to position the lighting device in the receiving tube. 
   
   
       3 . The ball as claimed in  claim 2 , wherein the receiving tube includes an enlarged head and the sleeve is received in the enlarged head. 
   
   
       4 . The ball as claimed in  claim 1 , wherein the switch unit includes a switch member, a spring, a mounting member and a button, the switch member is electrically connected with the power unity so that when the button is pushed, the mounting member compresses the spring to activate the switch member, the mounting member and the button are then moved back by the spring. 
   
   
       5 . The ball as claimed in  claim 1 , wherein the power unit includes a first conductive member, a second conductive member and a battery. 
   
   
       6 . The ball as claimed in  claim 1 , wherein the activation unit includes a circuit board, a conductive disk and a spring, the circuit board and the lighting unit are electrically connected with the power unit, the circuit board includes the conductive disk and the spring connected thereto, when the activation unit is activated, the spring is shaken and in contact with the conductive disk so as to light up the lighting unit. 
   
   
       7 . The ball as claimed in  claim 1 , wherein the lighting unit includes a lighting member which is connected to the circuit board having the activation unit. 
   
   
       8 . The ball as claimed in  claim 1 , wherein the lighting unit includes a lighting member which is connected to the circuit board which is electrically connected to the activation unit. 
   
   
       9 . The ball as claimed in  claim 2 , wherein a spring is located between a closed end of the lighting device and a closed end of the receiving tube, the spring biasing the lighting unit so that the protrusions on the lighting unit are securely engaged with the L-shaped slots in the receiving tube.
