Each casing 208 can be comprised of from a translucent, opaque or semi-translucent material, such as glass, acrylic, crystal, plastic or metal.
(43) Each casing 208 can be any desired height (e.g., 4 inches, 5 inches, 6 inches, etc.) and width (e.g., 2 inches, 3 inches, 4 inches, etc.). Although each casing 208 shown depicted in the exemplary embodiments is cylindrical, the casings 208 can take the form of any geometric shape that is known or may become known. As such, the casings 208 can be, for example, rectangular, square or oval or circular. The elongated body 270 can include at least one of a concave top portion, a sealed top portion or an open top portion. In an embodiment, the elongated body 270 can includes a cone arranged therein.
(44) To suspend the lighting system 200 from a ceiling or other structure or surface, the lighting system 200 can include at least one cord that is fixable to the housing 202. As shown, for example, in
(45) As illustrated in
(46) To aid in fixing the lighting system 200 at a desired height and angular orientation, the lighting system 200 includes a first splitter 296 associated with the first cord 280 and a second splitter 298 associated with the second cord 282. Each splitter 296, 298 is fastenable to the respective cord 280, 282 at a first position and through which the cord 280, 282 can extend and at a second position to fix the lighting system 200 at a desired height and angular orientation.
(47) As shown in
(48) A fastener or tightening mechanism 289, such as a set screw, can be arranged in the second holes 291 to aid in fixing the cords 280, 282 at a desired height and angular orientation and allows for adjustment of the length of the cords 280, 282 and the angular orientation of the lighting system 200, as desired. The first stop 221 at the second end of the first cord 280 can be arranged in the third hole 295, 297 to fix the second end of the cord 280 within the splitter 796 and second stop (not shown) at the second end of the second cord 282 can be arranged in the third hole (not shown) of the second splitter 298 to fix the second end of the cord 282 within the splitter 298.
(49) As shown in
(50) The lighting system 200 can be powered by a conventional AC power supply that provides current to the first and second light sources 236, 238. Electric current travels from the power supply above the ceiling or within the light system 200 to a power cord 327. The power cord 327 extends from the canopy 317 through the top plate 206 and into the housing 202.
(51) In the installation of the lighting system 200 power runs from a transformer (not shown). The transformer steps down the line voltage from a standard power line to 12 VAC or 24 VAC. Output wires that extend from the transformer are then installed to a LED driver 329, which normalizes the power and current needed to power the LED boards 240, 242. The LED driver 829 is installed in a remote and accessible location near the lighting system 200, preferably above the ceiling near the canopy 317. A mounting plate 331 is secured to the ceiling. Output wires 333 of the LED driver 329 are fed through the mounting plate 331 and an opening in the ceiling and are electrically connected to the power cable 327. The power cable 327 is electrically connected to the first light source 236 and second light source 238 to provide power to them and allow the light sources 236, 238 to illuminate.
(52) To assemble the lighting system 700, the height of the first splitter 296 is adjusted by loosening the fastener or tightening mechanism 289 and sliding the first splitter 296 up or down as desired. The power cord 327 and the first cable 280 are fed through a cord/cable bushing 337 and the first cable 840 is adjusted to the desired height. To shorten first cable 340, first cable 840 can be pushed into the bushing 337. To lengthen the first cable 340, the plunger can be depressed while pulling down the first cable 340 and releasing the plunger to lock it in place. Extra cable 340 can be stored in the canopy 317. The live wire of the LED driver 329 is connected to a live outlet box 341. A neutral wire of the LED driver 329 is connected to the neutral wire of the outlet box 341. A ground wire is connected to the ground wire of the outlet box 841. If no ground is present in the outlet box 341, the neutral wire can be connected to the mounting plate 331. All connections and the LED driver 329 are placed in the outlet box 341. The mounting plate 331 is then attached to the outlet box 341. To shorten or extend the second cable 342, push the second cable 342 can be pulled in an upward direction. To lengthen the second cable 342, the plunger can be depressed while pulling down on the second cable 342 and when a desired position is reached, the plunger can be released to lock the second cable 342.
(53) The exemplary embodiment of the lighting system 200 of the present invention shown in
(54) As discussed above, although the lighting system 200 depicts a housing 202 that includes four apertures 204, a plate 206 that includes four apertures 248 and four casings 208, four first light sources 240, at least one second light source 242 and four lenses 244, the application should not be limited to the specific number of elements of the lighting system 200 depicted in
