What is the illuminance of the production workshop before it is qualified?
1. Illuminance requirements of class C workshop: the illuminance standard of ultra-precision operation, design, drawing and precision inspection is 3000-1500. The standard of design room, analysis, assembly line and painting illuminance is 1500-750. The illuminance standard of packaging, metering, surface treatment and warehouse office is 750-300.
2. 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.
3. First, the measuring point of illuminance should be 0.85 m from the ground, 1 m to 2 m apart, and 1 m from the wall. Second, record the measured values and calculate the total average illuminance. Third, illuminance measurement generally does not include general lighting other than local lighting.
4. The general machining tolerance is greater than 0.1ax 0.75plane 300LX, and the precision machining tolerance is less than 0.1max 0.75plane / 500LX. Basically consistent with German standards.
5. The illuminance standard of the main workshop of the fireworks and firecrackers production plant should be 200lx, and the entrance and exit of the main production workshop should be provided with emergency lighting, the illuminance value should not be less than 10% of the normal lighting illuminance value of the place, and the emergency time should be 30min.
6. the standard of workshop lighting brightness is how much workshop lighting electricity is an important part of enterprise power consumption. Energy-saving transformation of workshop lighting system can not only reduce the production cost of enterprises, but also is of great significance to the development of energy saving and environmental protection in our country.
How appropriate is the illumination of the light?
1, how much illuminance is appropriate 2 the illuminance requirements of office lights: according to the national standard “Architectural Lighting Design Standard” GB 50034, 2004, ordinary offices, illuminance 300 lx, high-end offices, illuminance 500 lx
2, the brightness of the lamp, generally speaking, the normal light brightness under reading conditions should reach more than 300Lx, while the 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.
3. Illuminance requirements of office lights: according to the national standard “Architectural Lighting Design Standard” GB 50034Mir 2004, ordinary offices, illuminance 300 lx, high-grade offices, illuminance 500 lx.
4, generally speaking, the brightness of the table lamp in the range of 25-40 degrees is better for the eyes, and the incandescent lamp in this brightness range is often called the eye-protecting table lamp. At the same time, this brightness can also effectively ensure the lighting effect of 400-700 lux, which can ensure your normal use.
5. According to the architectural lighting design standard, the overall illuminance requirement of the bedroom is 75, (illuminance = luminous flux / area), the bedroom of 20 square meters needs 1500 luminous flux, and the ceiling lamp of 36W bedroom is just right. In addition, floor lamps or wall lamps can be installed at the head of the bed, which can be used as reading and night lights to supplement higher brightness.
What are the requirements for the installation height of general lighting in the factory building
1. General open lamps and lanterns, the distance from the lamp holder to the ground is not less than the following values (except when the voltage is used): (1) outdoor: 5m (installed on the outdoor wall); (2) factory building: 5m / 3) indoor: 2m / 4) the lamps and lanterns with the hoist of the soft cable are 0.m after the cable is unfolded.
2. When there is no requirement for the design, the installation height of the lamp is not less than the following values (except when the voltage is used): 1) outdoor: 5m (installed on the outdoor wall); 2) factory building: 5m / 3) indoor: 2m / 4) the lamps and lanterns with the hoist of the soft cable are 0.8m after the cable is unfolded.
3. According to the “Urban Road Lighting Design Standard (CJJ45-2015)”, the relationship between the light distribution type, layout and installation height and spacing of lamps and lanterns in Table 3 is as follows: Weff refers to the effective width of the road surface; the distance between S lamp poles; H refers to the installation height.
4. It shall be carried out in accordance with the regulations of the National Electrical installation regulations. You can participate in the designated legal low-voltage electrician training to get the specific application size details in the detailed regulations.
5. Indoor lamps and lanterns shall not be less than 4 meters from the ground and outdoor lamps shall not be less than 3 meters from the ground.
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.
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.
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.
