Lighting requirements for Class A factory buildings
Plant lighting brightness standards are as follows: ultra-precision operation, design, drawing, precision inspection lighting brightness standard 3000-1500. Design room, analysis, assembly line, painting lighting brightness standard 1500-750. Packaging, metering, surface treatment, warehouse lighting brightness standard 750-300.
Class A workshop standard: liquid with a flash point less than 28 ℃. A gas with a lower limit of explosion less than 10%. A substance that can decompose itself at room temperature or oxidize in air that can cause rapid spontaneous combustion or explosion. A substance that produces combustible gases and causes combustion or explosion under the action of water or water vapor in air at room temperature.
The lighting commonly used in the workplace inside and outside the production plant should ensure sufficient brightness. Lighting should be especially bright and sufficient in dashboards, stairways, and all narrow areas near the rotating parts of the machine and high-temperature surfaces, such as water level gauges, pressure gauges, vacuum gauges, thermometers, various recording instruments, etc.
Set up obstacle lighting tools where there are obstacles. If the selection standard of light source is a relatively low height office conference room and workshop, fluorescent lamps must be used in such occasions.
The light reflector of the industrial mine lamp in the workshop lighting must be able to produce lights of different brightness and width. Because the lighting effect requirements are also different in different operation processes, only industrial and mining lamps have more variety of changes and adjustments in order to better meet the needs of use.
Because there are too many kinds of industrial factories, different places have different requirements for illuminance, so the illuminance standards are also different. For example, the illuminance standards of light and heavy industrial plants must be different. Even in similar factories, the illuminance standards of different workshops and different processing precision sections are also different.
What is the national standard illuminance value of logistics warehouse?
1. The standard values of illuminance should be classified according to 0.130, 50, 7100, 150,200,300,500,750,1000, 1500, 2000, 3000, 50001x.
2. Legal analysis: the standard values of illuminance are classified according to 0.130, 50, 7100, 150,200,300,500,750,1000, 1500, 2000, 3000, 5000lx. Lx is the unit of illuminance.
3. The National Standard of Architectural Lighting Design GB 50034-2013 of the people’s Republic of China stipulates the general illuminance standard values for newly built, rebuilt and expanded residential, public and industrial buildings.
Illuminance requirements for Class C workshops
1. There should be sufficient natural lighting or artificial lighting in the workshop or work place. The lighting coefficient of the workshop should not be lower than the standard IV, the mixed illuminance of the working face of the inspection place should not be less than 540lx, the working face of the processing site should not be less than 220lx, and other places should not be lower than 110lx.
2, if the illuminance requires 70 and the quantity is between 26 and 36, depending on the luminous efficiency and distance-height ratio of lamps and lanterns, the greater the distance-height ratio, the less the quantity. 2, if the illuminance is 100-150, the quantity is about 40-54. 3, illuminance 300, the quantity is relatively large, 100PUE 120 or so.
3. Local lighting can be added in places requiring higher standard values of illuminance; in the same lighting room, when one or more parts of the work area need high illuminance, the general lighting mode of zoning can be adopted. Article 0.5 indoor ceilings, walls and floors should be decorated in light colors.
4. Because there are too many kinds of industrial buildings and different places have different requirements for illuminance, the illuminance standards are also different. For example, the illuminance standards of light and heavy industrial plants must be different. Even in similar factories, the illuminance standards of different workshops and different processing precision sections are also different.
5. It is not meaningful to use average illuminance in the work area, because there are several points below 150lx, which are not suitable for work. For the special requirements of high illuminance operation, local lighting can be used, but it is not suitable to raise the minimum illuminance standard of the whole workshop.
How many lumens are suitable for 12-meter factory building lighting?
Plant lighting brightness standards are as follows: ultra-precision operation, design, drawing, precision inspection lighting brightness standard 3000-1500. Design room, analysis, assembly line, painting lighting brightness standard 1500-750. Packaging, metering, surface treatment, warehouse lighting brightness standard 750-300.
Large factories and workshops can use 400W metal halide lamps or 400W LED of the same brightness.
Car workers’ workshop. How many lumens does lighting need to hit? A 20-watt lamp will suffice. The lights are very bright. Civil servants can work.
