Abstract

A device is designed for channeling electricity to a lamp, and adjusts downwards the amount of power channeled to the lamp as a function of available electrical energy in the source. In so doing, a reduction in the available energy in the source causes a less proportionate reduction in luminosity of the lamp. This might be accomplished by passing the electricity through a passive network of resistors and diodes on its way down to the lamp. In one example, the electrical energy source may be a battery that is powered by one or more solar panels. In that case, the device may also perform the function of protecting the battery from being overly charged. It channels downwards a greater daily lamp's energy consumption than that of daily electrical charging from the solar panels, when the available battery energy is near its full capacity.

Dependent claims

A device comprising:

an energy consumption routing circuit configured to selectively route electrical power from an electrical energy source to a lamp when the energy consumption routing circuit is coupled to the electrical energy source and to the lamp;
wherein when the energy consumption routing circuit routes electrical power from the electrical energy source to the lamp, the device is configured to adjust the amount of power delivered along the energy consumption routing circuit downward as a function of available energy in the electrical energy source, such that reduction in the available energy in the electrical energy source cause a less proportionate reduction in luminosity of the lamp.
