Abstract
A sun umbrella capable of emitting light in all directions comprising an umbrella rod and an umbrella disc. The umbrella rod is connected to an opening-and-closing device and is internally provided with a light strip. Circuit boards are fixedly assembled in the umbrella disc. The opening-and-closing device comprises light-transmitting tubes. Each light-transmitting tube is internally provided with a light strip, and the light strip is electrically connected to a power supply through a circuit board. The light-transmitting tubes are directly used as umbrella ribs. Copper-wire lights are arranged in the umbrella rod and the umbrella ribs and are directly connected to the circuit boards assembled in the umbrella disc, thus avoiding slotting process and achieving a simple assembly. The power supply is detachable and the power supply is stable and reliable. Through adopting the technical solution of the present disclosure, the production capacity is improved, and the cost is lowered.
