The modern lighting solutions are based on the research results showing that natural light is the decisive factor for the well‐being of every individual. This is the reason why the designers attempt to get as close as possible to its properties including illumination level. ILLUMINATION LEVEL The minimum values of illumination level for production areas are defined by the standard. Scientific researches and our practical experience are prooving, that adequate illumination level influences in positive way the performance of the employees, their ability to concentrate, decreases the mistake rate and the risk of injuries. To define minimum values of illumination level the standard EN 12464-1 distincts between the task area, where visual tasks are carried out, the sourrounding area – which immediately surrounds it, and the background, at least 3 m wide band adjacent to the immediate surrounding area. The decision what kind of lighting system should be installed depends on the visual task performed at the workplace. visibility of the working tool´s spike or pen’s nib is ensured. Such a direction of the luminous flux is determined for the right-handers; the left-handers are often disadvantaged in this case. However, currently there are lighting solutions which enable adjusting the luminous flux to create the same conditions also for the left-handers. The insufficient or erroneous lighting of the production area can have a negative impact not only on the quality of employees´ activities or quality of their performance, but also on their state of health and mind. The modern lighting solutions are based on the research results showing that natural light is the decisive factor for the wellbeing of every individual. This is the reason why the designers attempt to get as close as possible to its properties. Task Area From the point of view of demands on the illumination of the industrial and production area, it is the desk or the task area that plays the most important role. The European standard EN 12464-1 states the value of minimally 50 lux for the common working activities and automatic processing (drying, remote-operated processing installations, fuel supply plant) and tightens the requirements on the illumination level to the value of 1,500 lux for those task areas where time-demanding tasks, tasks requiring precision, productivity, concentration are carried out or where the visual capability of the employee is reduced (quality control, colour inspection, painting, manufacturing precious stones). To provide adequate values of illumination level of task area and to achieve constant lighting conditions supplementary luminaires like workplace luminaires and machine luminaires can be installed. From the point of view of safety it is also necessary to prevent the rise of the stroboscopic effect when the artificial lighting is on at the workplace. The stroboscopic effect represents an extreme danger, specially when working with the rotational tools because when the frequency and the rotational speed are the same an impression can arise, that the tool is off and it can cause hard injury to the user. The stroboscopic effect can be avoided by installing the LED luminaires or high-frequency control gears emitting the light with a frequency that the human eye cannot notice and therefore it perceives it as constantly continuous. Surrounding area The correct illumination of surrounding area (band with a width of at least 0.5 m around the task area within the visual field) and the background (at least 3 m wide adjacent to the immediate surrounding area within the limits of the space) is an important factor in the industry areas. Their correct illumination can prevent problems with perceiving the objects, it can minimise the damage of the sense of sight, developing stress and strain. Illuminance on the task area E task lux The illuminance of the surrounding area and the background is connected with the illuminance of the task area and is to ensure a harmonious distribution of brightness in the field of vision. The standard EN 12464-1 states that the illuminance of the immediate surrounding area may be lower than the illuminance on the task area but shall be not less then the values given in table below. LQS assigns the spaces meeting requirements of the standard 5 points; those failing to fulfil the illumination value level 0 points.

At workstations where employees are performing activities requiring accuracy, where sharp objects are used (e.g. drilling, grinding), or where activities include writing or drawing, the optimal solution is considered when the luminaire is placed towards the working surface slightly from the left of the employee’s view. When the situation is solved like this the employees do not cast a shadow upon the desk when they are working and also good Space for turning and measuring moderately fine parts presenting vertical and horizontal visual tasks Place for studying drawings on vertical surfaces Place for checking workpiece measurements and depositing tools presenting horizontal visual tasks Immediate surrounding area (band with a width of at least 0.5 m around the task area within the visual field) Single industrial workplace Various industrial workplaces require different lighting solutions for individual visual tasks. These must be defined individually in terms of location and intensity of illumination. The individual tasks may be combined and performed in the same working area.

The optimal solution is considered when the luminaire is placed towards the working surface slightly from the left of the employee’s view.

Big differences in the illumination rate create the impression of a broken space and increase demands on the adaptation capability of the human eye. LIGHTING UNIFORMITY The uniform illumination affects our ability to perceive the surrounding area and to orient ourselves inside of it. We perceive a uniformly illuminated space as a consistent one. An optimal state can be achieved by selecting an appropriate type and number of luminaires and their correct distribution. From the point of view of type of luminaires the direct and indirect lighting fixtures with a wide luminous intensity curve seem to be the most suitable. indirect XTp 150 ip 54 From this point of view the ergonomic quantity - lighting uniformity – is a matter of considerable importance in industrial and production areas. Big differences in the illumination rate create the impression of a broken space and increase demands on the adaptation capability of the human eye. The lighting uniformity index is adapted by the European standard EN 12464-1 which, as in the case of the illumination level, places heavier demands on workplaces requiring precision (e.g. drawing, grinding, decorating). For these ones it states the index with a minimal value of 0.7. The lighting uniformity is expressed as a ratio of the minimal and average illuminance of the space assessed. The closer their values are, the more uniform the illuminance of the space is. From the point of view of LQS, the optimal lighting solution meeting the standard is assessed by 5 points, those failing to fulfil requirements by 0 points. 90 90 LQS VALUE 75 75 100 60 150 60 200 45 250 45 cd/klm 30 15 0 15 30 C0.0-C180.0 C90.0-C270.0 Lighting uniformity Lighting uniformity LQS Value Yes 5 No 0 Luminous intensity curve of INDIRECT XTP C L2 FSD 2x36W A specialised software dialux enables a simulation of the lighting uniformity of the space already during the design phase of the lighting system.
