<p>PROBLEM TO BE SOLVED: To provide a luminaire for a color sorter downsized by reducing the number of illuminating means installed in an optical detecting part.SOLUTION: A luminaire for color sorter includes a long chassis 2 for heat dissipation, an LED substrate 3 installed on the chassis 2, and a light source 5 in which a number of LED elements 4 are arranged straight in a longitudinal direction on the LED substrate 3. The light source 5 formed by integrating at least two light sources 5a and 5b. The light source 5a illuminates a flow-down side in which a selected object flows, and the light source 5b illuminates toward a background 60 arranged to face a camera 59.</p> |
