ABSTRACT:
A rechargeable lamp assembly utilizing recharging contacts and a mounting unit for recharging purposes that contains mating contacts so that the lamp unit may be recharged when mounted on the mounting unit. The mounting unit includes another set of electrical contacts of the same configuration as those on the lamp unit. Thus a recharging unit for generating a recharging current may be utilized which is connectable either to the mounting unit, to recharge the lamp unit mounted thereon, or directly to the lamp unit. The lamp unit circuitry is adapted to accept any of a number of different recharging units, so as to provide for recharging from a battery source, an AC source, and an AC source with input power-failure indication. The bulb in the lamp unit may be releasably connected to the battery, so that the battery potential may be taken off as an independent power supply for another load, if desired.
