Golf ball containing photoluminescent material and a light source
First Claim
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.

Abstract
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.

-
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 of the outer shell; and a light-emitting circuit assembly embedded within the core, the light-emitting circuit assembly including a plurality of batteries, a control circuit coupled to the plurality of batteries, a plurality of light-emitting diodes coupled to the control circuit, and an impact switch electrically connected between the plurality of batteries 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, the impact switch including a metal casing connected to a terminal of the control circuit, and a metal spring suspended in the metal casing and electrically connected to one terminal of the plurality of batteries, the metal spring being adapted to vibrate sufficiently to contact the metal casing responsive to the golf ball being struck 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. - View Dependent Claims (17, 18, 19, 20)
