Patent ID: 7967465

Claim:
A light device arranged to receive at least one rechargeable electrical power storage device, said light device comprising: a flexible body portion movable between an expanded configuration and a contracted configuration and defining an enclosure when said body portion is in said expanded configuration, said body portion being at least partially transparent or translucent; at least one light emitting element which receives electrical power from said at least one rechargeable electrical power storage device disposed during use in said light device, said light emitting element being arranged so as to generate light which passes outwardly of said light device through said body portion; a solar power converting device arranged to convert solar power to electrical power for recharging said at least one rechargeable electrical power storage device, wherein said light device is disposable in an expanded configuration or a contracted configuration by respectively expanding or contracting said body portion; control circuitry arranged to control supply of electrical power to said at least one light emitting element during use; a test device disposed between said control circuitry and said at least one rechargeable electrical power storage device, said test device being disposable in a first configuration wherein electrical power is able to pass through said test device between said at least one rechargeable electrical storage device and said control circuitry, and a second configuration wherein electrical power is not able to pass through said test device between said at least one rechargeable electrical storage device and said control circuitry; and wherein said test device comprises an insulator, a first conductor disposed on a first side of said insulator and electrically connected to said at least one rechargeable electrical power storage device, a second conductor disposed on a second opposite side of said insulator and electrically connected to said control circuitry, and a test switch connected across said first and second conductors.
