Abstract:
1. A method for fabricating a lighting device including at least one solid state light emitter arranged on or over a substrate, the method comprising depositing at least one light-affecting element on, over, or around the at least one solid state light emitter using a three-dimensional printing process, and the method further comprises at least one the following features (a) to (f): (a) the at least one light-affecting element comprises at least one lumiphoric material; (b) wherein the at least one light-affecting element is deposited directly on the at least one solid state light emitter; (c) the at least one light-affecting element is deposited directly on the substrate; (d) the at least one light-affecting element comprises a cup or dam, and the method further comprises dispensing a liquid material, by a process other than three-dimensional printing, into a recess bounded by the cup or dam; (e) the at least one solid state light emitter comprises a first and a second solid state light emitter, and the at least one light-affecting element comprises a first light-affecting element deposited on, over, or around the first solid state light emitter and a second light-affecting element deposited on, over, or around the second solid state light emitter; and the method further comprises: obtaining or receiving information indicative of output characteristics of at least one of the first solid state light emitter and the second solid state light emitter; and adjusting at least one of material composition, material concentration, material curing, thickness, and shape of at least one of the first light-affecting element and the second light-affecting element based on said information indicative of output characteristics of at least one of the first solid state light emitter and the second solid state light emitter; wherein the at least one of material composition, material concentration, material curing, thickness, and shape differs among the first light-affecting element and the second light-affecting element; and (f) the at least one solid state light emitter comprises a first and a second solid state light emitter, the at least one light-affecting element comprises a first light-affecting element deposited on, over, or around the first solid state light emitter to yield a first optical distribution based on interaction between the first solid state light emitter and the first light-affecting element; the at least one light-affecting element comprises a second light-affecting element deposited on, over, or around the second solid state light emitter to yield a second optical distribution based on interaction between the second solid state light emitter and the second light-affecting element; and the first optical distribution differs from the second optical distribution.
