Abstract
A lighting device has an array of light emitting diodes (LEDs), an adhesion layer having portions with photo-activated electrical conductivity over the LEDs, and electrically charged scattering particles adhered by electrostatic attraction to the adhesion layer portions, thereby forming scattering regions that are self-aligned to the light emitting diodes. A method for manufacturing the lighting device includes photo-activating the adhesion layer using light output from the light emitting diodes to locally vary the conductivity of the adhesion layer; and attaching electrically charged scattering particles to the adhesion layer by electrostatic attraction.
