An engineered lighting system for use in an inspection system is comprised of an array of light emitting diodes. A specimen is brought into the viewing area, and a current pulse is provided to the diodes of the array to selectively flash all or a portion of the diodes of the array. Reflected light from the specimen is sensed and a digitized image is generated therefrom. An illumination level of the digitized image is adjustable, in whole or in part, by varying the effective lighting intensity of one or more of the diodes of the array during a flash period. The digitized image of the specimen is compared to data indicative of acceptability of the specimen, and acceptance or rejection of the specimen is decided on a basis of a comparison therebetween.

An engineered inspection lighting system comprising: a plurality of directed primary light generating elements directed to a primary light field; means for securing the primary light generating elements in a preselected array arrangement to form a primary lighting array; means adapted for directing light from the primary light generating elements to the primary light field; supply means for providing a single current pulse to selected light generating elements of the primary lighting array to illuminate an associated specimen within the primary light field; and the primary light field including a plurality of sections, the primary light generating elements being positioned in the primary lighting array such that each primary light generating element thereof does not contribute light equally to each section of the primary light field and wherein light in the light field from at least a portion of the light generating elements of the array is overlapped with light from neighboring light generating elements of the array.
