Product application and solution of lighting in LED factory building
The application of LED lighting can be divided into two parts: commercial lighting and civil lighting.
The high CRI obtained by using white LED with fluorescent powder has a price, because the Stokes shift will cause the efficiency of white LED to be lower than that of monochromatic LED. However, for most lighting applications, LED lamps with high CRI and slightly less efficiency are preferred.
Considering the ceiling height and design illuminance, it is necessary to choose suitable light distribution lamps and lanterns. It is recommended to use energy-saving LED industrial and mining lamps for medium-height ceilings with a height of about 5m. LED factory lamps with uniform illumination angle, no glare and no strobe are recommended. Lamp configuration suggestion: high-power LED industrial and mining lamp instead of high-pressure mercury lamp.
Factory workshop linear lighting scheme, grouping control light touching, how to design?
Press 1 lamp to illuminate a range of about 65 flat, to 110 sets of lights. About 11KW, calculation current 55A, total empty turn on 60A, below is divided into 4 loops, each circuit hangs 28 sets of lights, divides into empty turns on 20A.
Factory workshop lighting depends on the situation, from the height, within 5 meters, the use of fluorescent light source, can be achieved, general lighting requirements, between 5-12 meters, from energy-saving considerations, you can use LED light source lamps and lanterns; more than 12 meters, you can use metal halide lamps or sodium lamp light sources.
W high sodium lamp or 112W LED lamp, hang in the middle of the workshop, hang one every 13 meters, absolutely meet the needs. 250W high sodium lamp actual 300W LED lamp actual power 122W, power saving 60%, but the unit price is more than 4 times higher.
Reasonable choice of control switch and make full use of natural light: natural light is a free light source, to make full use of, so it is necessary to design a reasonable lighting switch. Make full use of natural light, correct selection of natural lighting, can also improve the working environment, make people feel comfortable and conducive to health.
Centralized control should be adopted in the lighting of public places such as corridors, stairwells and hallways of public and industrial buildings, and zoning and grouping control measures should be taken according to the conditions of building use and natural lighting.
How to design the lighting drawing according to the factory building structure drawing?
The main contents are as follows: 1. First, delete the other elements on the building drawing except for the main wall lines, door and window openings and main equipment layout drawings, and on this basis, draw electrical lighting drawings, weak electric plane drawings, kinetic diagrams and electrical system drawings.
2. According to one lamp, the lighting range is about 65 square meters, and 110 sets of lights are required. About 11KW, calculation current 55A, total empty turn on 60A, below is divided into 4 loops, each circuit hangs 28 sets of lights, divides into empty turns on 20A.
3. The load is calculated according to the number of lamps and electrical equipment such as inserts you choose in the plan, and is multiplied by the demand coefficient of different loads. There is not much power in the phase belt, the electricity is also distributed by itself, and the difference between the maximum phase current and the minimum phase current is no more than 30% ok. But the current per phase is not higher than 16A.
4. (1) Indoor lighting: interior lighting of factory building and office and other ancillary rooms. (2) Outdoor installation lighting: lighting for various outdoor installations.
Design Essentials of Industrial Lighting
The basic elements of lighting design are: illuminance determination: industrial building illuminance standard is determined according to “Industrial Enterprise Lighting Design Standard” TJ34-79; civil building illuminance, before the national standard is promulgated, should be selected according to the “Building Electrical Design Technical regulations” according to the use requirements.
Led lamps and lanterns design key points first of all, about the lamps and lanterns design principles, to take into account the optical design of lamps and lanterns as well as its materials and costs, which is a very important link, followed by the aesthetic degree. Everyone likes beautiful things, LED lamps and lanterns are furniture supplies, naturally its appearance and shape is also very important.
Article 0.3 in addition to abiding by this standard, the lighting design of industrial enterprises shall also comply with the requirements of the relevant national standards and norms. Chapter II Lighting methods and Lighting types Article 0.1 Lighting methods can be divided into general lighting, zonal general lighting, local lighting and mixed lighting.
Factory workshop lighting depends on the situation, from the height, within 5 meters, the use of fluorescent light source, can be achieved, general lighting requirements, between 5-12 meters, from energy-saving considerations, you can use LED light source lamps and lanterns; more than 12 meters, you can use metal halide lamps or sodium lamp light sources.
Some bright and lively, some soft, can show the unique personality of the light and exude extraordinary artistic charm through the contrast. In the use of home lighting, the bedroom should be warm, the study and kitchen should be bright and practical, the living room should be rich, hierarchical and artistic conception, the dining room should be romantic, and the bathroom should be warm and soft.
300LX Illumination for Lighting Design of Industrial buildings
1. The precision machining tolerance is less than 0.1ax 0.75plane / 500LX. Basically consistent with German standards.
2. Although the symbol lx refers to the illuminance of the light, the illuminance of the light is also closely related to the wattage of the lamp. In general, 300lx illuminance is equivalent to 300W LED lamp, can not understand the concept of 300W, like our household LED lamp is impossible to have such a high wattage.
3. LX refers to the international unit of illumination (SI), also known as meter candlelight. Illuminance is a unit of light intensity, its physical meaning is the luminous flux per unit area, the unit of illuminance is the number of lumens (Lm) per square meter, also known as Lux.
4. Lx is the meaning of illuminance unit, read as “Lux”, commonly known as “lumen”. Lumen units are used to evaluate the lighting intensity per unit area. Different light sources have different luminous coefficients, the most commonly used are color temperature coefficient and illuminance coefficient.
5. The illuminance of LX is usually 300W fluorescent lamp. The calculation process is as follows. If the fluorescent lamp is set to x watts, then the x * luminance / m2 “300Lxx” 300* luminance / m2, so the xlamp 300 (watt) 300lx is generally the illuminance requirement and specification (for example, the general lighting of offices and shops is above 300lx). Select a specific light source according to the specification.
6. The symbol of illuminance is e, and the unit is lx (lux). The symbol of luminance is l, the unit is cd/ square, read Kendra per square meter. Not ix but lx,lux Lux, the unit of illuminance. You can refer to gb 50034-2004 for these things. The previous terminology section is described in more detail. I hope I helped you.
