According to the invention, the lighting device comprises a substrate 103 having a surface and a cavity within the surface. At least one light emitting diode (“LED”) is mounted to the cavity 104, and a monolayer comprising phosphor particles overlies the LED. The phosphor monolayer 106 is adhered to the LED by a monolayer of transparent adhesive material 105. An optional optical thick layer of transparent material is placed on the phosphor monolayer to encapsulate the LED and optionally form a lens. A method and apparatus for making these devices are disclosed.n n n n Lighting, Light Emitting Diode, LED, Cavity, Adhesion |
