Abstract:
1. A controller for an LED lighting system, the controller being a first part of a control unit and comprising: a battery charge switch for selectively coupling a solar panel to a battery for selective starting and stopping of charging of the battery; and a battery discharge switch for selectively coupling the battery to a lamp for selectively turning the lamp on and off, a battery discharge set driver that, when triggered, causes the battery discharge switch to be set to an on-state, wherein the battery discharge set driver may be triggered if the battery discharge set driver is in a standby state, but not if the battery discharge set driver is in a resting state; a battery discharge reset driver that, when triggered, causes the battery discharge switch to be reset to an off-state, wherein the battery discharge reset driver may be triggered if the battery discharge reset driver is in a standby state, but not if the battery discharge reset driver is in a resting state; wherein when the battery discharge switch is in an on-state, the battery discharge switch connects power to the battery discharge reset driver to prepare the battery discharge reset driver in the standby state, and disconnects power from the battery discharge set driver to prepare the battery discharge set driver in the resting state, wherein when the battery discharge switch is in the off-state, the battery discharge switch connects power to the battery discharge set driver to prepare the battery discharge set driver in the standby state, and disconnects power from the battery discharge reset driver to prepare the battery discharge reset driver in the resting state, wherein the lamp contains a second part of the control unit for protecting the battery from over-charged and over-drained conditions such that the second part of the control unit is not present within the controller.
