Abstract

A projector light device includes two or more conductor bars received in a track, a pedestal slidably engaged in the track, two or more conductors secured in the pedestal and each having a flap engageable into the track for electrically contacting with the conductor bars. A projector light member is attached to the pedestal and electrically coupled to the conductors. An actuator device is rotatably received in the pedestal and has an actuator for forcing the flaps of the conductors to engage with the conductor bars when the actuator device is rotated relative to the pedestal.

Claims (17)

1. A projector light device comprising:

a track including a passage and a pair of channels formed therein and communicating with each other,

a pair of conductor bars secured in said channels of said track respectively for coupling to electric power source,

a pedestal slidably engaged in said passage of said track,

a pair of first conductors secured in said pedestal, and each including a flap extendible outward of said pedestal and engageable into said channels of said track for electrically contacting with said conductor bars respectively,

a projector light member attached to said pedestal, and electrically coupled to said first conductors respectively, and

means for selectively actuating said flaps of said first conductors to engage with said conductor bars respectively, and to electrically couple said projector light member said conductor bars, said selectively actuating means including an actuator device rotatably received in said pedestal and having an actuator element selectively engaged with said first conductors, for forcing said flaps of said first conductors to engage with said conductor bars respectively when said actuator device is rotated relative to said pedestal.

2. The projector light device according to claim 1 , wherein said pedestal includes a base secured therein and having a barrel extended therefrom, said projector light member includes a coupler secured to said barrel, for attaching said projector light member to said pedestal.

3. The projector light device according to claim 2 , wherein said pedestal includes a space and an orifice formed therein and communicating with each other, said base is received in said space of said pedestal, and said barrel is extended through said orifice of said pedestal.

4. The projector light device according to claim 2 , wherein said barrel is a threaded barrel, said coupler of said projector light member is threaded and secured to said threaded barrel.

5. The projector light device according to claim 1 , wherein said pedestal includes an opening formed therein, said first conductors each includes a seat received in said opening of said pedestal, said projector light member includes two electric wires secured to said seats with fasteners.

6. The projector light device according to claim 1 , wherein said actuator device includes a post extended therefrom, said actuator element is extended from said post.

7. The projector light device according to claims 1 , wherein said actuator device includes a knob provided thereon for rotating said actuator device relative to said pedestal.

8. The projector light device according to claim 1 , wherein said track includes a groove formed therein and communicating with said passage thereof, a second conductor bar is secured in said groove of said track, said pedestal includes a second conductor secured therein and having a flap extendible outward of said pedestal and engageable into said groove of said track for grounding purposes.

9. The projector light device according to claim 8 , wherein said actuator element of said actuator device is selectively engaged with said second conductor, for forcing said flap of said second conductor to engage with said second conductor bar when said actuator device is rotated relative to said pedestal.

10. The projector light device according to claim 8 further comprising a plug slidably received in said passage of said track, and including a third conductor provided thereon and slidably engaged with said second conductor bar.

11. The projector light device according to claim 10 , wherein said plug includes a bulge laterally extended therefrom and slidably engaged into said groove of said track, and said third conductor is provided on said bulge.
