Abstract
A rechargeable lamp system includes a set of one or more self-standing rechargeable lighting fixtures (luminaries) removably received on a recharging platter. The luminaries each include a light diffusor resembling a candle that turn on when removed from the charging platter. The luminaries also turn on when power to the charging platter is turned off, which allows the set to be used as a table lamp, and has the added benefit of turning the luminaries on automatically during a power failure. The luminaries are each inductively coupled to the recharging platter, which enables to provide an aesthetically pleasing interface free of electrical contacts.
