Q:How to choose industrial plant lighting fixtures?

       A:Industrial workshop lighting is mainly workshop lighting, workshop lighting and warehouse lighting, which workshop lighting requirements are higher, generally 40OLX ~ 1000KX, workshop lighting to 2O0LX ~ 300LK is the best, warehouse lighting is 5OLX ~ 100LX.

Industrial plants can be broadly classified into the following three types:
1. General production plant: the plant that is produced under normal environment.
2.Explosion and fire hazard production plant: the plant that normally produces or stores explosive and fire hazard materials.
3. Production plant in bad environment: production plant with dust, humidity, high temperature or steam, vibration, smoke dew, acid and alkali corrosive gases or substances, radioactive substances. Therefore, according to the above classification and characteristics, from the perspective of high efficiency, practicability and safety, we should strictly follow the different production conditions for factory lighting design.

Industrial lighting should achieve a certain degree of illumination to ensure the comfort and safety of workers, do anti-dazzle processing. Industrial plant lighting through the horizontal, vertical or oblique work surface required to observe the details of the object, color contrast and surface texture materials to define the level of conventional lighting, reasonable conventional lighting to the whole ground area and work face lighting levels to achieve balance; Attention should be paid to the control of glare, so that the light is directed to the working surface and will not cause direct or reflected glare. The light source with comfortable light color and good color rendering can be used, and the light source can be concealed, or the light source can be reasonably matched with the grille and the reflector.
General factory lighting requirements should follow the following principles:
1. Selection of lighting mode
1) For places with high illumination requirements, small working position density and unreasonable use of general lighting alone, mixed lighting should be adopted.
2) when a work area needs to be higher than - general illumination can be used when partition general illumination.
3) when the area - general lighting can not meet the illumination requirements should be added local lighting.
4) Only partial lighting should not be installed in the working area.

2. Lighting quality control
Lighting quality is a sign to measure the quality of factory lighting design. It mainly includes the following contents:
1) Choose lamps with high efficiency and appropriate light distribution curve. According to the lamp hanging height in the workshop rack according to the chamber index ruler, the value of the lamp with different light. Ri is the index of refraction of the lamp. When RL =0.5~0.8, narrow light distribution lamps should be selected;
When RI=0.8~1.65, medium light distribution lamps should be selected; When RI=1.65~5, wide light distribution lamps should be selected.
2) Choose lighting sources with appropriate color temperature and color rendering index in line with production requirements.
3) Reaches the specified illumination uniformity: the illumination uniformity of general lighting in the working area shall not be less than 0.7, and the illumination uniformity of the vicinity of the working area shall not be less than 0.5.
4) To meet the quality requirements of direct glare limit: the uniform glare value (UGR) shall be specified in GB 50034-2004. That is, the general allowable value is 22 and the fine machining value is 19. 5) Take measures to reduce the influence of voltage fluctuation and voltage flicker on lighting and prevent stroboscopic effect.

3. Lighting source selection for industrial workshop
The light source should be selected according to the characteristics and requirements of the production process. The lighting source should be electrodeless lamp. Please refer to this entry). The three basic color fine diameter straight tube fluorescent lamp, gold halide lamp or high pressure sodium lamp. Light source point from the ground height in 4m and below the appropriate selection of electrodeless lamp and thin tube fluorescent lamp; High-height factory buildings (above 6m) generally use electrodeless lamps such as available high-pressure sodium lamps without color display requirements.

At present, because the industrial plant lighting, the light source to frequent switch, instantaneous start place; Of night or high pressure operation, need to avoid glare at the same time, long lamp, power consumption, energy saving, power saving, save money so, on the choice of industrial workshop lighting source generally choose electrodeless lamp, because electrodeless lamp the characteristics of high efficiency and energy saving, long life 100000 hours, not only electricity-saving, and avoids the high cost of maintenance. It has no glare, good color rendering and, most importantly, can start instantly. Therefore, it is widely used in industrial workshop lighting.

4. Selection of lighting fixtures
Factory lighting lamps should be selected according to the environmental conditions, to meet the working and production conditions, and appropriate attention to the appearance of beautiful, convenient installation and coordination with the building, so as to achieve technical and economic rationality. In addition, when selecting the type of lamps according to the environmental conditions, attention should be paid to the environmental temperature, humidity, vibration, pollution, dust, corrosion, explosion and fire dangerous media, etc. Sub-conditions of 3 kinds of environment will choose lamps and lanterns below.
A selection of lamps for industrial plants:
1) in the normal environment (heating or non-heating places) generally use open lamps.
2) Where there is a lot of dust but there is no risk of explosion and fire, the lamps and lanterns suitable to the dust value should be selected. The amount of dust in a dusty environment is measured by the concentration in the air (mg/m3) or the amount of settling [mg/(m2-d)J.

For general dusty environment, it is appropriate to use dustproof (IPSX level) lamps. For dusty environment or the existence of conductive dust in general dusty environment, it is appropriate to use the dust-tight type (IP6X level) lamps. IP65 lamps should be used in the environment of conductive fibers such as carbon fibers. For lamps and lanterns that often need to be flushed with water, lamps and lanterns of no lower than IP65 should be selected.

The clean room is the area in the factory where the environmental conditions need to be strictly controlled. The main role of lighting is to make work activities clearly visible, thus forming safe, comfortable and effective working conditions.
