Method and apparatus for chip-on board flexible light emitting diode

A lighting device, comprising:

• a plurality of LED chips mounted on a continuous planar flexible substrate, wherein the continuous planar flexible substrate is disposed in an arcuate orientation forming a 360 ring having a hollow center;
• wherein the plurality of LEDs comprises an optical axis that is normal to the continuous planar flexible substrate and wherein the optical axes of the plurality of LEDs are parallel;
• a heat sink having an arcuate surface shaped to approximate the arcuate orientation of the continuous planar flexible substrate and coupled to the flexible substrate between a face of the continuous heat sink and a back of the continuous planar flexible substrate;
• a power source coupled to the plurality of LED chips;
• an LED collimated into a spot beam, said collimated LED disposed adjacent the plurality of LED chips, said collimated LED having an optical axis that is parallel to the optical axes of the plurality of LEDs.

A lighting device mounted in a hand-held flashlight, comprising:

• a first light source comprising:
• plurality of LED chips mounted on a planar flexible substrate, wherein the planar flexible substrate is disposed in an arcuate orientation forming a ring with a hollow center, wherein each of the plurality of LED chips comprises an imaginary axis normal to the planar flexible substrate wherein the imaginary axis of each of the LED chips is parallel to one another;
• a heat sink disposed in contact with a back of the planar flexible substrate;
• and
• a power source coupled to the plurality of LED chips;
• a second light source comprising:
• a spot beam LED disposed adjacent the first light source, the spot beam LED having an imaginary axis normal to the planar flexible substrate of the plurality of LED chips.
