PROBLEM TO BE SOLVED: To provide a portable luminous golf ball luminous device, capable of radiating enough quantity of light in a short time to store light by a light storage ball without glaring due to exposure of light when the light luminous emits light. SOLUTION: The luminous golf ball on the ground is covered with a radiation chamber 2, light radiated from a stroboscope built in a light applying body 1 is diffused and amplified by a reflector a of the inner surface of the radiation chamber 2 so that the light is not exposed to the outside by a light shielding body b on the outer surface of the radiation chamber 2, whereby light is uniformly applied to an object.
