What is Good Lighting?
Many factors should be considered for good lighting (such as the color, spread, direction and amount of light). The structure of the illuminated surface is also important. A dark gray, dirty surface reflects only 10-12% of the light falling on it, while a clean, clear surface may reflect more than 90%.
The illumination should be bright enough to provide easy visualization and the direction of propagation should not dazzle. At the same time, the lighting level should be high enough to provide easy vision.
(Glare makes it difficult to see and reduce the capacity to work, but also increases the number of accidents. Working under dazzling light can lead to eye disorders. Therefore, it is necessary to protect the eye from unwanted glare.)
Lighting is one of the issues that need to be emphasized is the brightness of the light in the field of view that prevents the sight or causing discomfort. This brightness can be direct or reflection. To prevent glare, the light is placed above the line of sight or covered with a dull (opaque) or semi-transparent material.
The glare of the light can be caused by the fact that a surface reflects the image of the light source directly to the line of sight (eg polished control panels or machine displays). These reflections can be avoided by preferring slightly matte surfaces rather than polished or smooth surfaces.
Lighting with daylight
In the industry, various types of work and manufacturing processes, windows or roof lighting can provide adequate lighting.
When such a lighting is preferred, the location of workstations, machines and workbenches should be well ed, taking into account the direction and intensity of the light. Basic approaches such as the fact that daylight doesn´t make glare on the work surfaces, the light doesn´t come directly and light into the eyes of the employees and the location of the machines and operations according to the lighting requirement should be carefully considered.
When using daylight in industry, the basic approach is to plan the distribution of this light to all processing areas in an equal way. It is known that the most suitable lighting approach is lighting from the roof. On the other hand, it should be remembered that the light coming from the windows also rests the eyes of those who look out from time to time and that it has a beneficial effect in some respects by maintaining relations with the outside world.
As for roof-to-roof lighting, as well as saw-type roofs, daylight is predicted by a daylight factor in one direction. This is the equivalent of at least 250 lux lighting. This lighting level is expected to be at least 85% during the year and during working hours. In order to achieve daylight effect, it may be necessary that the entire area of ??the windows where the sunlight can enter indirectly is one-tenth to half the size of the workplace.
In daylight illumination, it should be foreseen that the daylight factor should be brought to the minimum dimensions for the most niche places, if possible, in view of the fact that the light will not be distributed at the same level throughout the factory.
In artificial lighting projects, it is taken into account that as much as every business mail, generally all the workplace needs lighting. In the meantime, considering the development projects, the establishment of lighting systems can also be considered. Light sources for artificial lighting are distributed well all over the factory, and special light sources are used to respond to this need in areas requiring special lighting.
Most of the employees who work in tables, bench surfaces, assembly tables and similar work conditions work by sitting down. Optimization of seating heights is also necessary in such places.
As a matter of fact, the sitting height of a chair that can not be adjusted and the feet do not touch the floor or the legs of people who do not fit under the table is not high efficiency. As well as adjusting the height of the seat, it is necessary to consider the volumes where the legs can easily fit.
The skillful and easy-to-work approach to the work of the working surfaces is used in the research of the dimensions of the working surfaces. The research carried out for this purpose, table height of 105 cm. Whereas, it has been shown that sufficient efficiency can be obtained from standing work, and that the reduction of this height to 92 cm is an acceptable height arrangement. The researchers stated that the top level of the table is 5-10 cm lower than the operating elbow. All of our measurements are based on regulations, standards, employer and employee obligations.
