How to arrange factory lighting?

(Last Updated On: September 21, 2018)

In modern factories, many jobs require workers to use high-intensity eyes to complete, workers must have good vision, and they must concentrate on a certain workpiece or a certain point to complete. There is also a lot of work that requires workers to use their eyes for a long time to complete, or even work overtime to complete.

In some factories, night shift workers complete their work while others are resting. This is hard on the eyes; In this situation, workers will soon feel visual fatigue, difficulty in concentrating, and thus affect work efficiency, and even cause mistakes and accidents.

So a comfortable and bright working environment is very important for factory workers, not only to protect their eyes, to relieve eye fatigue but also to improve work efficiency.

So what should the factory lighting design do?

First, the task of factory lighting is to ensure good visibility in the work environment, to make work safer and more active, to avoid accidents, to reduce the number of faults and unqualified product, and to improve productivity.

Second, a good factory lighting design should have sufficient, uniform light in the work area, high luminous flux, proper color temperature, and reduced glare.

Next, we will explain to a few points:

Lighting method:

  1. Classification of lighting methods

There are three main aspects of factory lighting: general lighting, local lighting, and hybrid lighting.

General lighting: Also called the main lighting, generally placed in the middle of the top, providing overall illumination to space, usually according to the size of the factory.

Local lighting: According to the production needs, usually work with general lighting, where the special key lighting is required, the lamps are placed to illuminate the working point.

Hybrid lighting: generally used in large factories, with main lighting and local lighting to match each other, reducing light and dark areas and shadow areas.

The cleaning shop uses general lighting to achieve the required brightness.

 

2, the choice of lighting methods

  • For the illuminance requirement is high, the working position density is not large, and the place where the general lighting is unreasonable should be using mixed lighting.

(2) If the illumination requirement of the operation is not high or is limited by the production technical conditions, it is not suitable for installing local illumination, or when the mixed illumination is unreasonable, general illumination should be adopted separately.

Good factory lighting design has sufficient and uniform light in the work area, high luminous flux, suitable color temperature, and reduced glare. The comfortable working environment encourages employees to increase production and product quality.

(3)Partitioned general illumination can be used when a work area needs to be higher than the general illumination.

(4) Partial illumination should be added when the general illumination of the zone does not meet the illumination requirements.

General lighting can not meet the brightness requirements of the assemble work, need to increase local lighting.

(5) Local lighting should not be installed only in the work area.

 

2 Reasonable illumination

The illumination factors affecting visual illumination of factory lighting mainly include illumination level, brightness distribution, color appearance, light and shadow color, etc., but these factors have different effects on work efficiency, and illuminance is the biggest.

The illumination standard of general illumination of industrial buildings also has standard regulations. For the work surface where local illumination needs to be increased, the added local illumination brightness value should be selected from 1-3 times of the general illumination illumination value of the place. In addition, the specific workplace lighting standards of various types of factories should also be designed in accordance with the relevant industry regulations.

Illumination standard values on the workplace surface:

However, when high-intensity gas discharge lamps are used as general illumination, the standard value of illumination should not be lower than 50Lx in workplaces where people are often working. For general lighting in hybrid lighting, the illuminance value should be 5% to 15% of the illuminance value of the mixed illumination at this level. The illuminance should not be lower than 30Lx. However, when using high-intensity gas discharge lamps, it should not be lower than 50Lx.

 

3Lamp selection

  1. Types of lamps

Factory lamp selection is directly related to the light intensity of the working environment, and directly affects the work efficiency, so factory lamp selection is critical. The main lighting sources commonly used in factory workshop lighting are metal halide lamps, electrodeless lamps and LED lamps.

Among them, LED lighting is the most promising prospect. We usually use the factory workshop lighting fixtures as factory lights or high bay lights. Designing and selecting suitable lighting fixtures can not only save energy but also greatly improve work efficiency and comfort.

Then how to use the luminaire depends on the height of the factory building to determine the luminaire and light source to be used.

2, choose the factory lighting fixtures should follow the terms below:

 

1 should consider easy maintenance and safe use.

2 Should use dustproof, waterproof or led explosion-proof lights for the workshop with explosive gas or dust. The control switches should not be installed in the same place. Explosion-proof switches should be used when they need to be installed in the same place.

3 For wet indoor and outdoor places, sealed luminaire or open lamps with waterproof ports should be used.

4 Floodlights should be used in hot and dusty places.

5 For corrosive gases and particularly humid indoors, sealed luminaire shall be used. The components of the lamps shall be treated with anti-corrosion treatment, and the switchgear shall be protected.

6 Dust-free indoors, according to the amount of dust discharge and its nature, should be use sealed luminaire

7 In the factory where the lamp may be damaged by mechanical damage, the lamp with protective net shall be used; if there is a place for forging, air compressor or bridge crane in the vibration place, the lamp with anti-shock device shall be used.

A factory is a place for production and processing. The main purpose of industrial lighting is to increase productivity, ensure product safety and create a comfortable visual environment. There is an inseparable relationship between lighting and work efficiency. Whether lighting is good or not directly affects the overall production efficiency.

Therefore, when designing the illumination of the factory, it should be based on the corresponding lighting standards and the actual site needs through reasonable lighting calculations, lighting arrangements, to ensure a certain level of lighting, reducing the productivity caused by insufficient lighting.
