Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to an illuminative device or a light device, and more particularly to a decorative light device having a rotary actuating member.




2. Description of the Prior Art




Various kinds of typical light devices have been developed for generating lights, warning lights, etc., and comprise one or more batteries coupled to one or more light bulbs or the like, and a switch disposed or coupled between the batteries and the light bulbs, or coupled in the electric circuit to the light bulbs, for controlling the energizing of the light bulbs. The switches normally include a switch button to be depressed or actuated by the users in order to control the on and off of the light bulbs.




However, the switch button may be depressed inadvertently, such that the light bulbs may be energized inadvertently, and such that the batteries may be consumed inadvertently.




Some of the typical light devices may include a control ferrule rotatably attached to a light housing, and movable relative to the light housing, for adjusting the light beam of the light devices. However, the rotational movement of the control ferrule relative to the light housing may not be used for controlling the on and off of the light bulbs.




The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional light devices.

or the heads


44


.




It is to be noted that the conductors


43


,


47


may be made with or without the heads


44


,


48


. The formation or the provision of the heads


44


,


48


on the ends of the conductors


43


,

FIGS. 5

,


7


), and to make sure that the conductors


43


,


47


may be absolutely disengaged or separated from each other (

FIGS. 4

,


6


).




It is further to be noted that the conductor


47


and the heads


48


may be rotated and caused to be disengaged from the other conductor


43


and the heads


44


thereof by the follower


60


or by the knob


73


, and the conductor


47


and the heads


48


will have no chance to be engaged with the other conductor


43


and the heads


44


inadvertently when the conductor


47


or the heads


48


are rested in the depression(s)


37


of the peripheral wall


38


of the bucket


34


.
