Selection and design of factory lighting fixtures

Selection and design of factory lighting fixtures缩略图

1, the scope of factory lighting design and its types

Factory is the production of established products. Generally consists of production plants, research and development, office, logistics and other ancillary buildings, various types of outdoor installations, stations, fields, roads and so on.

The scope of factory lighting design includes indoor lighting, outdoor installation lighting, station lighting, underground lighting, road lighting, security lighting, obstacle lighting and so on.

(1) Indoor lighting: the internal lighting of production plant and the internal lighting of R&D, office and other auxiliary rooms.

(2) Outdoor lighting: Lighting for various outdoor installations. Such as the shipbuilding industry's open-air workplace, petrochemical companies, tanks, reaction towers, building materials companies, rotary kiln, belt corridor, metallurgical companies, blast furnace, ladder, platform, power station gas cabinets, the total step-down substation outdoor transformers, power distribution devices, outdoor pumping station cooling rack (tower) and outdoor ventilation and dust removal equipment, lighting.

(3) station lighting: station, railroad grouping station, parking lot, open yard, outdoor test pads and other settings of the lighting.

(4) Underground lighting: basements, cable tunnels, integrated corridors and tunnels within the lighting.

(5) Evacuation Lighting: Lighting set up in the evacuation channel of the plant building is effectively recognized and used.

(6) guard lighting: along the perimeter of the plant and key places around the guard area set up lighting.

(7) Obstacle Lighting: plant area with special high buildings, structures, such as chimneys, etc., according to regional aviation conditions, according to the relevant provisions of the need to install the sign lighting.

2, industrial plant characteristics
Industrial plants can be divided into single-story and multi-story industrial buildings according to their building structure type. The vast majority of multi-storey industrial buildings in light industry, electronics, instrumentation, communications, medicine and other industries, such plant floors are generally not very high, and its lighting design and common scientific research and experimentation buildings and other similar, more fluorescent lighting program. Machining, automobile, metallurgy, textile and other industries, production plant - generally single-story industrial buildings, and according to the needs of production, more multi-span single-story industrial plant.

Single-story plant to meet certain building modulus requirements on the basis of process needs to determine its building width (span), length and height. The span of the plant (B) - generally: 6, 9, 12, 15, 18, 21, 24, 27, 30, 3 ….. The length of the plant (L): less than a few dozen meters, more than a few hundred meters. Height of the plant (H): low 5 ~ 6m, high up to 30 ~ 40m, or even higher.

The span and height of the plant is the main factor to consider in the lighting design of the plant. In addition, according to the continuity of industrial production and the need for transport of products between sections, most industrial plants with cranes, their lifting capacity can be as small as 3 ~ 51 tons, up to hundreds of tons. (At present, the machinery industry single crane lifting capacity of up to 800t). Therefore, factory lighting fixtures - generally installed in the top of the plant, the high space plant is usually fixed installed in the roof frame. Metal roof of the plant lamps can be fixed installed in the bar, grid structure of the plant lamps can be fixed installed in the grid, according to the need, part of the lamps can be installed on the wall or column.

3, the choice of factory light source

Lighting source should be selected according to the characteristics and requirements of the production process, should meet the production process and the environment on the color rendering, start-up time and other requirements, and should be based on the light source efficiency, life, etc. in a comprehensive technical and economic analysis and comparison to determine.

Control room, laboratory, test room, instrumentation, electronic components, numerical control processing, pharmaceutical, textile, food, beverage, cigarette production, as well as the height of 7 ~ 8m and the following production sites should be used in the thin tube straight tube-shaped three-color fluorescent lamps

Higher height of the plant (more than 15M) can choose metal halide lamps.

No color requirements can be selected high-pressure sodium lamps.

In addition to the prevention of electromagnetic interference has strict requirements, with other light sources can not meet the special places, the factory "should not use ordinary incandescent lamps.

4, LED lights

With the development of LED light source, LED lights into the field of factory lighting is an inevitable trend. LED lighting fixtures have multiple advantages, become an excellent alternative to traditional lamps and lanterns, can provide a better production environment for the workshop plant.

High luminous efficiency. With large-scale machinery industrial workshop plant roof are relatively high, large space, so the lamps and lanterns need to be relatively high power. LED lighting has a large luminous flux, high efficiency, from the ceiling height and the design of illumination considerations, it is very suitable for the selection of high-power, wide irradiation angle, illumination uniformity, non-glare, no flicker of the LED floodlights or industrial lamps.
In order to meet the illumination requirements at the same time, LED lighting fixtures low power consumption, environmental protection, durable. For the reduction of environmental pollution, save factory lighting costs are playing a very positive role.
Long life. In the appropriate current and voltage, the service life of LED can reach more than 50,000 hours. According to the average daily lighting time of 24 hours, equivalent to at least 5 years of continuous use. Of course, LED floodlights as a workshop plant lighting fixtures used in the initial investment cost is high, but because the LED light source has a high luminous efficacy, long life characteristics, in the long run, can bring considerable economic benefits for the factory.

The general color rendering index of LED lamps for general lighting should comply with the following

Provisions.

(1) long-term work or stay in the place, Ra should not be less than 80, installation height of more than 8m large space places Ra should not be less than 60;.
(2) used to distinguish the color requirements of the place Ra should not be less than 80.
(3) for color testing of local lighting Ra should not be less than 90.
Special color rendering index R, should be greater than 0.
