A conventional flexible connecter assembly for track lighting device in accordance with the prior art comprises a first connector segment and a second connector segment. Each of the first and the second connector segment has a first end being in a plug-in type tapping mechanism for joining the connector segments mechanically and electrically to electrical distribution track sections. At least one lamp is screwedly mounted to the track sections. A flexible member is formed of a first coiled wire element and a second coiled wire element are concentrically wrapped in opposite directions with respect to each other. The first and second coiled wire elements are respectively joined at first end of the first connector segment and at second end of the second connector segment. The first and second coiled wire elements define a tubular passageway for a first and a second electrical conductor coupling the connector segments electrically, and the flexible member itself provides a ground connection between the connector segments and corresponding track sections. The construction of the flexible member permits the positioning ofjoined track sections at a variety of angles with respect to each other and protects the first and second electrical conductors passing therethrough between the connector segments.
Although the flexible connecter assembly for track lighting device has a flexible and expandable member permitting the positioning of joined track sections at a variety of angles, such that the track lighting device is able to be mounted to different environments. However, the at least one lamp is screwed to the track sections. The at least one lamp is not easy to detach from the track sections for maintenance. Moreover the assembly of the flexible connecter assembly for track lighting device is not simple.

A width of the first groove 13 is relatively narrower than that of the second groove 14. A first electricity conducting plate 11 is disposed along an inner periphery of the first groove 13. A second electricity conducting plate 12 is disposed along an inner periphery of the second groove 14. The first electricity conducting plate 11 and the second electricity conducting plate 12 are adapted to be correspondingly connected to a negative electrode and a positive electrode of a power supply.
The luminaire device in accordance with a preferred embodiment of the present invention further comprises at least one illuminating device 3 detachably connected to the guiding rail 1. Each illuminating device 3 comprises an illuminating member 32 for providing illumination effect. The illuminating member 32 includes a holder 321 and at least one light source 322 mounted on one end of the holder 321 and electrically connected to the holder 321. In this embodiment, the at least one light source 322 is two arc-shaped cold cathode fluorescent lamps. The at least one light source 322 may be of any suitable type such as light emitted diodes, halogen lamps or the like. The illuminating member 32 has one end electrically connected to a clamp 31 extending therefrom.

The first body 311 has a first clamping head 3111 and a first pressing portion 3112 respectively formed on two opposite ends thereof. The first clamping head 3111 has a first electricity conducting unit 3114 disposed on a first surface 3113 thereof. The first body 311 includes an electric wire 3116 having two ends respectively connected to the first electricity conducting unit 3114 and the illuminating member 32. The first clamping head 3111 has a first protrusion 3115 extending from the first surface 3113 thereof and adjacent to the first electricity conducting unit 3114. The first protrusion 3115 is in a shape corresponding to the first groove 13.
The second body 312 has a second clamping head 3121 and a second pressing portion 3122 respectively formed on two opposite ends thereof. The second clamping head 3121 has a second electricity conducting unit 3124 disposed on a second surface 3123 thereof. The first surface 3113 and the second surface 3123 are facially arranged to each other. The second body 312 includes a third electricity conducting unit 3126 having two ends respectively connected to the second electricity conducting unit 3124 and the illuminating member 32. The second clamping head 3121 has a second protrusion 3125 extending from the second surface 3123 thereof and adjacent to the second electricity conducting unit 3124. The second protrusion 3125 is in a shape corresponding to the second groove 14.
The clamp 31 further includes a resilient unit 313 mounted between the first pressing portion 3112 and the second pressing portion 3122. Two ends of the resilient unit 313 respectively abuts against the first pressing portion 3112 and the second pressing portion 3122 for tending to push the first pressing portion 3112 and the second pressing portion 3122 aside, such that the first clamping head 3111 and the second clamping head 3121 are simultaneously rotated about the pivot axis to be closed together for clamping the guiding rail 1 tightly. When the first pressing portion 3112 and the second pressing portion 3122 are pressed close to each other, the first clamping head 3111 and the second clamping head 3121 are simultaneously rotated about the pivot axis, such that the clamp 31 is disengaged with the guiding rail 1. In accordance, the at least one illuminating device 3 is detachable for easy maintenance and changing an illuminated area.
