Because of its small size, an ice hockey puck can only be seen with difficulty by spectators during fast play. To ensure that the ice hockey puck is clearly visible in poor lighting conditions and in television transmissions, and to enable spectators to follow the progress of the game, the puck is provided in its centre with a recess (2) to receive at least one light source (3), and light channels (7) are arranged leading from this light source (3) to its peripheral surface (4) and/or to the edges of its two lateral surfaces (5, 6), said channels being filled with a highly transparent material. |
