1. A lighting device, comprising:
- a lighting module comprising;
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; and
a selection unit used to be coupled to a power source and selecting 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.

Abstract
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.

15. A lighting device, comprising:
-
a lighting module comprising; a plurality micro-diodes formed on a substrate; and a conductive wire pattern connecting to the micro-diodes; at least two alternating current (AC) electrodes electrically coupling an AC power source to the micro-diodes by the conductive wire pattern, such that a first portion of the micro-diodes are turned on during a positive half cycle of the AC power source and a second portion of the micro-diode are turned on during a negative half cycle of the AC power source; and at least two direct current (DC) electrodes, coupling a DC power source to the micro-diodes by the conductive wire pattern. - View Dependent Claims (16, 17, 18, 19, 20)
