Patent attributes
A photoluminescent, light-emitting golf ball comprises a substantially solid core with an outer shell, both formed of a light transmissive material. Photoluminescent particles are distributed within the light transmissive material. A light-emitting circuit assembly embedded within the core includes 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 battery and the control circuit. The control circuit actuates the light-emitting diodes for a predetermined time period in response to an impact of the golf ball by a golf club. Actuation of the light-emitting diodes by an impact on the golf ball excites the photoluminescent particles, causing the particles to glow in excess of the predetermined time period of actuation of the light-emitting diodes.
