Patent ID: 7179181

Claim:
An illuminating ball, comprising: an inflatable ball composed of multiple layers and having a hole; a rubber tube attached to an inner surface of the ball and in alignment with the hole; a power supply device that provides power, and being retained in the rubber tube, the power supply device comprising: a battery holder formed as a hollow column with an open top and a closed bottom, a bottom conductive plate being mounted on the closed bottom, the battery holder including: a flange formed around the open top, the flange having two opposed gaps defined therethrough, and two engaging notches defined on the flange but not through, each engaging notch being adjacent to a respective one of the gaps; and a first conductive pad and a second conductive pad respectively mounted in the two notches; a battery received in the battery holder, a first end of the battery electrically contacting with the bottom conductive plate, a second end of the battery facing the open top of the battery holder; and a covering tube formed by a solid head portion and a sleeve with an opening, the sleeve extending from the head portion, a screw head being integrally formed on the head portion, and a conducting spring being mounted on a bottom surface of the head portion and electrically contacting to the second end of the battery, the covering tube including: a slot defined on the screw head, and a conductive block protruding from an outer surface of the covering tube for engaging with one of the notches of the battery holder; a vibration-triggered switch, connected to the power supply device and operating in one of a manual mode and a vibration-sensitive mode; multiple output wires connected to the vibration-triggered switch; and multiple light emitting elements connected to the output wires and mounted on the ball wherein the first and second conductive pads are electrically connected to the vibration-triggered switch and the output wires, and wherein when the power supply device is operated in the vibration-sensitive mode, the vibration-triggered switch automatically turns on to activate the light emitting elements when the ball experiences vibration from impact with a surface.
