Claim Text:
1. A method of inspecting a surface finish of a component, the method comprising: positioning the component with respect to an array of light emitting diode (LED) lighting fixtures each having parallel LED tubes and a plurality of reflectors arranged at an angle of approximately 45 degrees relative to horizontal; generating light via the array with a predetermined set of lighting characteristics, including a striped pattern, a beam angle of at least 120 degrees, a color rendering index of at least 85, and a color temperature of about 5000 degrees Kelvin; illuminating the component with the generated light from the array, including reflecting light from the parallel LED tubes from the reflectors to generate six stripes of light per LED lighting fixture; inspecting the surface finish of the component for defects while illuminating the component with the generated light from the array; and executing a control action with respect to the component when the component contains at least one of a threshold number and a threshold size of the defects.
