MODULAR HIGH DENSITY LED ARRAY LIGHT SOURCES

摘要

A modular array light source assembly is provided, preferably comprising a plurality of solid-state LED array modules. Modules may be abutted to provide a large area, high intensity, and high-density array. Preferably, in each module, a linear or rectangular array of groups of LED is provided in which the density of LED die is higher at ends or edges of the modules abutting other modules, to provide improved uniformity of irradiance over the illuminated area between modules. Particular arrangements of clusters of LEDs are provided that reduce or overcome the discontinuity or dip in irradiance due to edge or wall effects caused by the spacing of LED die from edges of the substrate/packaging of each module. These arrangements are advantageous for hermetically sealed LED array modules, for example, which require a minimum wall thickness for an effective seal.
