What are the architectural lighting design standards?
According to the standard of architectural lighting design, the domestic lighting design is generally divided into two stages, the architectural design institute completes the basic lighting of the construction project, and some professional companies contract the design of large halls, venues and landscape lighting.
Residential buildings have natural lighting of stairwells and walkways. In addition to emergency lighting, energy-saving self-extinguishing switches should be used. The number of light sources controlled by each lighting switch should not be too large. The number of lights in each room should not be less than 2 (except for those with only one light source).
It mainly stipulates the lighting standard value, lighting quality and lighting power density of residential, public and industrial buildings. The Standard for Architectural Lighting Design may need to be partially revised in the future, and the information and provisions about the partial revision will be published in the Journal of Engineering Construction Standardization.
All kinds of rooms and activity places in underground buildings should be equipped with general lighting, operating tables, cashier tables, registration offices and other working parts should be provided with local lighting, business hall shelves, offices, guest rooms, testing rooms, etc., and local lighting can be set up if necessary. Underground buildings shall be provided with normal lighting, emergency lighting, duty lighting and transition lighting.
The overall floodlighting uses high-power spotlights or lamps to show the magnificent atmosphere and concise visual beauty of the whole building. two.
What are the requirements for the tube-tube energy-saving lamps used in the lighting of industrial buildings?
As the evaluation standard of lighting energy saving, the above two standards respectively specify the lighting power density (current value and target value) of the illuminated room or place, that is, the upper limit of lighting power consumed per unit area of the illuminated room or place.
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.
Among them, the self-developed Huanghui tube energy-saving lamp has a power-saving rate of up to 70% and is an enterprise specializing in green lighting and creating energy-saving pioneers.
High color rendering, closer to sunlight, soft light: fast start, no strobe, color return to reality, eliminate light pollution, effectively protect eyes. The wet color is above Ra:86. The tube in the tube is designed with a special structure, and the light tube contains a superreflective light film, which emits useless light into the effective irradiation range and increases the illuminance.
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.
LED lighting for square meters requires about 15W: first of all, LED lighting lamps and lanterns, in the same lighting environment, in order to achieve the same lighting effect as fluorescent lamps, usually only half the power of fluorescent lamps. Which means saving half the money.
General lighting is 3 to 5 watts per square meter. The W LED lamp is equivalent to about 5W incandescent lamp, which is similar to the energy-saving lamp. What we are talking about here is to refer to the Development trend of Lighting Light Source in the August issue of Architectural Electrical.
Special lamps and lanterns set up in large places such as warehouses, supermarkets, gymnasiums, etc. Height 12 meters wide 21 meters long 84 meters with 200W LED industrial and mining lamps 18-20 can be. One lamp can illuminate an area of about 100 square meters, then the factory area described by the landlord; 20 200W industrial and mining lamps are sufficient.
How appropriate is the illumination of the light?
According to the national standard “Architectural Lighting Design Standard” GB 50034 lx 2004, ordinary office, 300 lx illuminance, high-end office, 500 lx.
The brightness of the first light, generally speaking, the normal light brightness under reading conditions should reach more than 300Lx, while ordinary indoor lighting generally has only 100Lx, so table lamps should be used when reading at night to increase the brightness of the light. In terms of subjective feeling, when reading, we must feel that the lighting of the book is very bright, which can meet the standard.
Illuminance requirements of office lights: according to the national standard “Architectural Lighting Design Standard” GB 50034Mur2004, ordinary offices, illuminance 300 lx, high-grade offices, illuminance 500 lx.
What is the illuminance standard of industrial lighting factory building?
1. The standard values of illuminance in different places vary from 50lx~750lx. Please refer to the “Building Lighting Design Standard” GB50034-2004 illuminance specification, you can get the place illuminance standard value you want.
2. The illuminance standard values of industrial enterprises should be classified according to the following series: 0.130, 50, 7100, 150,200,300,500,750,1000, 1500, 2000 and 3000Lx. 2. The standard value of lighting design should be the average illuminance value on the working surface of the production site.
3, inspection, etc., the lighting brightness is required to be not lower than 500lux. In addition, the type, quantity and layout of light sources installed in the workshop need to be considered in order to achieve the best lighting effect and working environment. Maintaining proper workshop lighting brightness can not only improve the work efficiency and accuracy of workers, but also prevent light pollution and occupational diseases.
4. The national standard of the people’s Republic of China [Architectural Lighting Design Standard] GB 50034-2013 specifies the general illuminance standard values for newly built, rebuilt and expanded residential, public and industrial buildings.
5. Does your so-called factory need rough processing or fine processing of large pieces? Different processes require different lighting illuminance, ordinary large rough processing requires illuminance of 70 lux, then fine illuminance of 100-150, fine processing illuminance of 300 lux.
6. According to the use of the factory, the requirements of the contrast degree are also different, which can be a wide range. It is assumed that the average illuminance of the general production workshop (not precision equipment) should be above 300Lx (lux), and the color rendering Ra should be above 80. The load density should be below the 15W/ threshold.
What are the regulations for the lighting of workplaces inside and outside the production plant?
The number of light sources controlled by each lighting switch should not be too large. The number of lights in each room should not be less than 2 (except for those with only one light source).
The third point is for the evacuation passageway, the illuminance of the evacuation passage should not be less than 0.51%.
Will correctly release the power supply, will cardiopulmonary resuscitation, will stop bleeding, will bandage, will transfer and transport the wounded, will deal with emergency trauma or poisoning and so on. If you find someone electrocuted, you should immediately cut off the power supply, make the electrocuted person off the power supply, and give first aid, such as working at high altitude, when rescuing, we must pay attention to prevent the danger of falling from high altitude.
The lighting equipment in the temporary power supply at the construction site stipulates which lighting circuits and lamps are less than 1.8 meters. Warning lighting on the protective railing around the foundation pit. Wet places include lighting in deep foundation pits. Lighting working in metal containers should use a safe voltage of 36v or 24v or 12v.
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.
