The construction characteristics of industrial buildings require significant changes in lighting illuminance and various lighting methods. The selection of lighting sources, especially in special places, requires strict requirements. Due to the varying degrees of precision in industrial production, there are also different requirements for illumination. The lighting requirements for precision machining workshops (1000-1500 lux) are much higher than those for general machining workshops (75-200 lux), while the lighting requirements for inspection work are higher. Corresponding lighting methods should be adopted according to the density of the production working face. For example, intensive production workshops often use general lighting or partitioned general lighting, while non intensive production workshops use mixed lighting. Due to the different nature of work and the height of the ceiling, different light sources should be used in the production workshop. For example, for workshops with a ceiling height higher than 10 meters, gas discharge lamps should be used; For workshops with a ceiling height of 6-10 meters, it is recommended to use gas discharge lamps with reflective lampshades, wall lamps with upward oblique light, and column lamps; The workshop with a ceiling height of less than 5 meters and engaged in relatively fine work mainly uses fluorescent lamps. For workplaces that require color recognition, lighting sources with high color rendering index should be used. Special production sites, such as explosive gases, combustible dust, hazardous materials, moisture, water droplets, corrosive gases, and vibration prone areas, should adopt corresponding safety lighting measures. The design steps first determine the lighting method based on the visual characteristics of the working object, the distribution density of the working surface indoors, and other conditions; Then, based on the minimum size of the identified object and the characteristics such as the contrast between the identified object and the background brightness, the required illuminance and lighting quality are determined according to the lighting standards; Then, based on the spatial size and illuminance requirements of the lighting site, determine the lighting source and lighting fixtures, as well as their suspension height, etc; Finally, perform lighting calculations to determine the required light source power and number of lamps, or calculate illuminance based on predetermined power. In addition, corresponding lighting safety measures should be considered for special production sites. Inspection lighting is an inspection lighting device set up in the quality inspection work of industrial products in order to detect any abnormalities in the objects that need to be identified early and accurately for corresponding processing. The method of inspecting lighting depends on the glossiness and brightness of the inspected object. For inspection objects with glossy surfaces, recognition difficulties may arise due to the reflection of light projected onto them; To reduce and eliminate this interference, the direction of light irradiation should be consistent with the observation direction, or the light should be directed from the observer's left or right side, or diffusion lighting should be used. For inspection objects with surface defects, centralized lighting devices are generally used to improve the lighting effect. For moving inspection objects, high illumination is required, and it is easier to observe and inspect when the inspection object is moved horizontally than vertically. For places where color is checked, lighting sources with suitable color rendering should be selected based on the inspection content
