Factory lighting design scope and types
A factory is a place where a given product is produced. It is generally composed of production plant R & D offices, logistics and other ancillary buildings, outdoor cereal plants, stations, yards, roads, etc.
Factory lighting design scope includes indoor lighting, outdoor installation lighting, station lighting, underground lighting, road lighting, sanitation lighting, obstacle lighting, etc.
(1) Interior lighting: interior lighting of the production plant, research and development, and office interior lighting.
(2) Outdoor device lighting: Lighting for various outdoor devices. Such as the shipyard’s open-air operation site, the kettles, tanks and reaction towers of petrochemical companies, rotary kilns of building materials companies, belt corridors, blast furnace furnaces, ladders, platforms of metallurgical companies, gas tanks of power stations, and total pressure reduction Lighting for outdoor transformer substations and substations, cooling racks (towers) for outdoor pumping stations, and outdoor ventilation and dust removal equipment.
(3) Station yard lighting: Illumination of stations, railway marshalling stations, parking lots, open storage yards, outdoor test yards, etc.
(4) Underground lighting: lighting in basements, cable tunnels, integrated pipe corridors and tunnels.
(5) Evacuation lighting: The lighting that is effectively identified and used in the evacuation passages in the factory buildings.
(6) Guard lighting: Lighting set up along the perimeter of the factory area and around guard areas of key places.
(7) Obstacle lighting: There are super tall buildings and structures in the factory area, such as chimneys, etc. According to the regional aviation conditions, the signs need to be installed according to relevant regulations.
This chapter focuses on the lighting inside the production plant. For other lighting, please refer to the relevant chapters of this manual.
Characteristics and classification of industrial plants
1. Industrial plant features
Industrial plants can be divided into single-story and multi-story industrial buildings according to their architectural structure. The majority of multi-story industrial buildings are found in light industry, electronics, instrumentation, communications, medicine and other industries. The floors of such workshops are generally not very high. Their lighting design is similar to common scientific research and experimental buildings, and more fluorescent lighting solutions are used. The production workshops in industries such as machining, automobile, metallurgy, and textile are generally single-story industrial buildings, and according to production needs, more are multi-span single-story industrial workshops.
On the basis of meeting the requirements of a certain building modulus, a single-storey factory building determines its building width (span), length and height depending on the process needs. The span of the factory building (B) is generally: 6,9,12,15,18,21,24, 27,30,36m …, the length of the factory building (L): from tens of meters to hundreds of meters. Building height (H): 5 ~ 6m low, 30 ~ 40m high, or even higher. The span and height of the plant are the main factors considered in the design of the plant lighting. In addition, according to the needs of industrial production continuity and the transportation of products between T sections, most industrial plants are equipped with city cattle, Yangdi, Lili, Xiaoqiancho, 3 ~ 5t, large Jingshi and city (single crane in the machinery industry of the day before) The lifting weight is up to 8R. Ming Dynasty lamps are generally installed in 100 public places. Tall space workshops are usually fixed on roof trusses. Factory roof luminaires on metal roofs can be fixedly installed on tags. Netting-structured factory luminaires can be fixed on grid frames. On, cast Zhaian, some lamps can be installed on the wall or on the pole.
