LIGHTING DEVICES

摘要

Lighting devices capable of being powered by both AC and DC power sources without requiring AC power source to the DC power source conversion are provided, in which a lighting module comprises a plurality of micro-diodes formed on a substrate and a conductive wire pattern connecting to the micro-diodes, wherein the conductive wire pattern has at least three voltage feed points. A selection unit is coupled to a power source and selects at least two of the voltage feed points, such that a portion of the micro-diodes and the power source form at least one loop thereby turning on the micro-diodes in the loop.
