Abstract:
1. A light-emitting device comprising: a water-proof enclosure; a motion-actuated switch, disposed in the water-proof enclosure, for generating a triggering signal according to an external force; a controller disposed in the water-proof enclosure, the controller generating a lighting signal according to the triggering signal when the controller is under an active condition, and the controller entering an inactive condition when the controller does not receive the triggering signal within a pre-determined period, wherein during the inactive condition, the controller stops generating the lighting signal even receiving the triggering signal generated by the motion-actuated switch, the controller is not able to be switched to the active condition in accordance with the triggering signal; an active switch, only capable of resetting the controller from the inactive condition to the active condition; a memory unit, disposed in the water-proof enclosure, for storing a plurality of default patterns; a 2D light-emitting array having at least three columns and three rows, disposed on the outside of the water-proof enclosure and comprising a plurality of light-emitting diodes; a driving unit, disposed in the water-proof enclosure, the driving unit being electrically connected to the controller, the memory unit, and the 2D light-emitting array, the driving unit selecting one of the plurality of default patterns in a pre-determined way according to the lighting signal from the controller, and the driving unit driving the 2D light-emitting array according to the selected default pattern, wherein the pre-determined way is a sequential way; and a battery, mounted in the water-proof enclosure, for supplying said light-emitting device with electrical power.
