LIGHTING SYSTEM FOR HOT ENVIRONMENT, IMAGING DEVICE, AND ELECTRONIC COMPONENT MANUFACTURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a lighting system for a hot environment, an imaging device and an electronic component manufacturing device capable of illuminating an illuminated object with uniform illuminance even in a hot environment and of executing visual recognition for positioning even in a hot environment. SOLUTION: These devices are each provided with an illumination member 110 equipped, on both surfaces in the width direction of a substrate 111 formed of quartz glass being a translucent material and having heat resistance, with diffused illumination light generation part 114 for uniformly refracting the light fed to the substrate at random to turn it into uniform diffused illumination light. Accordingly, photographed objects 2 and 5 are irradiated with uniform illuminance by the illumination member and its image is picked up even in the hot environment, so that the visual recognition for positioning can be executed with high accuracy.
