发明名称 Solid state lighting device with different illumination parameters at different regions of an emitter array
摘要 Solid state lighting (SSL) devices and methods of manufacturing such devices. One embodiment of an SSL device comprises a support and an emitter array having a plurality of SSL emitters carried by the support. The emitter array has a central region and a peripheral region outward from the central region. Individual SSL emitters in both the central and the peripheral regions have a primary emission direction along which an intensity of light from the SSL emitters is highest, and the primary emission direction of the SSL emitters in the central region is at least substantially the same direction as the primary emission direction of the SSL emitters in the peripheral region. Additionally, a first coverage area ratio of the SSL emitters in the central region is different than a second coverage area ratio of the SSL emitters in the peripheral region.
