摘要： A modular LED array light source comprises an assembly of a plurality of solid-state LED array modules. Modules are abutted to provide a large area, high intensity, and high-density array that provides substantially uniform irradiance. Preferably, in each module, a linear or rectangular array of groups of LED is provided in which the density of LED die in the array 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.

摘要： The present invention provides a toolholder mountable on a lathe or other machine tool for supporting a cutting plate relative to a workpiece for cutting or shaping the workpiece. The toolholder including a body having a tapered tool base at one end thereof, the tool base defining a tool seat for supporting a cutting plate. A plug screw having a head defining threads on an outer surface thereof for engaging a threaded hole in the tool base is also provided. The plug screw further defining a shank extending eccentrically from the head, the shank being receivable through a mounting hole defined by the cutting plate for locating the cutting plate relative to the tool seat upon rotation of the plug screw relative to the tool base. A lock nut is provided for receiving a threaded end of the shank for securing the cutting plate to the tool base and toolholder.
