Bent perimeter lighting and method for fabricating
View Patent ↗A method for bending a perimeter light and a perimeter light for illuminating curved surfaces. One embodiment of a bending method according to the present invention comprises heating a perimeter light to make it pliable. A radius tool is then provided having a curved surface with a shape and radius for the desired bend in the perimeter light. The heated perimeter light is mounted to the radius tool curved surface. The perimeter light is then cooled and removed from the radius tool. One embodiment of a bent elongated perimeter light according to the present invention comprises an array of light sources and an elongated tube bent to match a curve or shape. The array of light sources is disposed within the tube and the tube transmits and disperses the light from the array to give the appearance that said array of light sources is a continuous light source. The array of light sources is cuttable at intervals to shorten the array while allowing the remaining light sources in the array to emit light. The tube is also cuttable to match the length of the array. A system for mounting perimeter lights to body has straight and curved surfaces comprises a plurality of straight and bent elongated perimeter lights that are mountable in a daisy-chain to the straight and curved surfaces.
1. A bent elongated perimeter light, comprising:
an array of light sources that are illuminated by electric power;
an elongated tube bent to match a curve or shape, said array of light sources disposed within said tube, said tube transmitting and dispersing the light from said array giving the appearance that said array of light sources is a continuous light source;
said array of light sources being cuttable at intervals to shorten said array while allowing the remaining light sources in said array to emit light, said tube being cuttable to match the length of said array, wherein said array of light sources comprises an array of light emitting diodes (LEDs) wherein said array of LEDs comprises a plurality of parallel connected sub-arrays of LEDs; and
a plurality of printed circuit boards, wherein each of said plurality of parallel connected LED sub-arrays is mounted to a respective one of said PCBs, each of said PCBs electrically connected in series such that an electrical signal applied to said series is transmitted to said PCBs, wherein said tube further comprises a track and each of said PCBs contains a washer to ride on said track to mount said PCBs within said tube.
2. The perimeter light of claim 1 , wherein said array of LEDs are capable of being cut between two of said plurality of parallel connected sub-arrays to shorten said LED array.
3. The perimeter light of claim 1 , wherein said array of LEDs is capable of being cut between two of said serially connected plurality of PCBs to shorten said LED array.
4. The perimeter light of claim 1 , further comprising a means for anchoring said bent perimeter light to a structure.
5. The perimeter light of claim 1 , further comprising an anchoring slot integral with said perimeter light and a plurality of mounting buttons, said mounting buttons mounted to a structure and cooperating with said slot to hold said perimeter light on the structure.
6. The perimeter light of claim 1 , further comprising first and second conductors to transmit said electrical power from the input of said LED array to the output for connecting said perimeter light to another device, wherein the cutting of said LED array does not interrupt the conduction of said electrical power along said first and second conductors.
7. The perimeter light of claim 1 , further comprising bumpers mounted at the ends of said tube to protect said LED array, said bumpers being compressible to compensate for the expansion and contraction of said tube and LED array.
8. The perimeter light of claim 1 , wherein said linear array of light sources comprises a linearly aligned array of light emitting diodes (LEDs) mounted on a substrate.
9. The perimeter light of claim 1 , wherein said array of LEDs is mounted to a flexible circuit board material.
10. The perimeter light of claim 1 , further comprising a voltage/current control device at each of said plurality of parallel connected sub-arrays of LEDs.
