Lighting device adapted for synchronous control
First Claim
1. A lighting device, comprising:
- a switch element coupled to a power source;
a bridge current rectifying unit in communication with the switch element for converting alternating current received from the power source into direct current;
a driving and light-emitting module in communication with the bridge current rectifying unit; and
a counting and control unit having one end coupled between the switch element and the bridge current rectifying unit, and another end coupled to the driving and light-emitting module for counting a switching number of the switch element, and selectively outputting one or both of a first enable signal and a second enable signal to the driving and light-emitting module to execute a corresponding function according to the switching number of the switch element.

Abstract
A light body includes a counting and control unit which counts a switching number of a switch element, and outputs a corresponding enable signal to a driving and light-emitting module to emit light of a selected feature according to the switching number of the switch element. The light body further includes a bridge current rectifying unit in communication with the switch element for converting alternating current received from the power source into direct current. For allowing two or more light bodies to be synchronously controlled, the switching signal indicative of the counted switching number is substantially simultaneously transmitted to the counting and control unit of each of the light bodies without passing through the bridge current rectifying unit.

10. A lighting device, comprising:
-
a light-emitting source for providing an illumination light; a switch element coupled to a power source; and a driving and control device in communication with the switch element and the light-emitting source for counting a switching number of the switch element, and selectively outputting one or both of a first enable signal and a second enable signal to the driving and light-emitting module to execute a corresponding function according to the switching number of the switch element, wherein the driving and control device starts over the counting of the switching number of the switch element once the switch element is in an off state for a time period longer than a preset time period, and the driving and control device includes a capacitor for power supply to the counting and control unit within the preset time period in order to maintain the work of the counting and control unit durin the off state of the switch element. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
