Abstract
A method and apparatus to equalize the voltage across each light bulb in a low-voltage lighting system, commonly found in the yards of private homes and businesses. The present invention consists of a power compensation element that is inserted in-line with each light bulb connected to the bus lines that distribute current from a power source, such as an electrical transformer, to the light bulbs. The function of the power compensation element is to compensate for the voltage drop along the bus lines due primarily to the electrical resistance of the bus lines. Therefore, a compensation rating of the power compensation element may depend upon its location along the bus lines and the electrical resistivity of the bus lines, as well as the internal electrical resistance of the light bulbs. The preferred embodiment is an electrical resistive power compensation element where the rating of the element is its resistance value. One alternate embodiment is an electrical transformer power compensation element where the rating is the transformer ratio of output-to-input voltage, while another alternate embodiment is a diode-based, voltage-limiting circuit power compensation element, typically with equal rating where the rating is the voltage-limiting reference level of the circuit.
