1. A photoluminescent, light-emitting golf ball comprising;

  • a substantially solid core formed of a light transmissive material;

    an outer shell formed of a light transmissive material surrounding the substantially solid core;

    photoluminescent particles distributed within the light transmissive material; and

    a light-emitting circuit assembly embedded within the core, the light-emitting circuit assembly including at least one battery, a control circuit coupled to the at least one battery, a plurality of light-emitting diodes coupled to the control circuit, and an impact switch electrically connected between the at least one battery and the control circuit to actuate the light-emitting diodes for a predetermined time period responsive to an impact of the golf ball by a golf club;

    whereby actuation of the light-emitting diodes by an impact on the golf ball excites the photoluminescent particles distributed within the light transmissive material, causing the particles to glow in excess of the predetermined time period of actuation of the light-emitting diodes.
