Lighting device utilizing light active sheet material with integrated light emitting diode, disposed in seam and/or in low profile application

A method of making a light source, comprising:

• providing a first substrate arranged into at least two facing surfaces which form a seam therebetween;
• providing a lighting device that includes a plurality of light emitting diode (LED) chips, and two second substrates that have planar first surfaces that face each other and that sandwich and are electrically connected to the plurality of LED chips, the LED chips are embedded in the lighting device in a linear arrangement by a material that mechanically adheres the LED chips to the second substrates at the planar first surfaces and electrically isolates the LED chips from each other, wherein the plurality of LED chips generates light photons, wherein the lighting device has a first edge and a second edge opposite to the first edge, the first edge and the second edge have planar second surfaces that face each other, the light photons within the lighting device that are emitted by the plurality of the LED chips from a top surface of said LED chips being output from the lighting device at the second edge of the lighting device, the planar second surfaces of the first edge and the second edge are perpendicular to the top surface of said LED chips;
• sandwiching the lighting device in the seam between the two facing surfaces of the first substrate;
• arranging the seam into an opened position;
• and
• exposing the second edge of the lighting device within the seam, from between the two facing surfaces of the first substrate that form the seam which is in the opened position.
