Reduced operating costs
In the operation of an installation, The industrial lighting is included as an issue in various reflections, all of whom have an economic dimension, direct or indirect. The improvement is an investment that „attaches“ and the anticipated benefit is important both in absolute financials and indirectly, through increased employee performance.
The Industrial Lighting is an operating cost can be reduced
The direct cost of industrial lighting consists of the following parameters:
- purchase cost of energy consumed
- maintenance and periodic replacement of luminaires and
- purchase cost of replacement or repair damage
and there are also indirect costs, as the cost of failure to harvest the productive capacity of the area because of maintenance or troubleshooting. Improving the lighting system can lead to reductions in operating costs since intervenes Above three parameters. Keeping the same requirements in light intensity (Lumens), simple replacement luminaires with daylight systems Suntracker can lead to increased rates of return (luminous efficacy, σε Lm / KWh) and to make substantial reductions in the cost. This reduction may be from 16-30% or in some cases greater, depending on the design, and the pooling of natural lighting.
Industrial Lighting and Productivity
O industrial lighting efficiency is.
The efficiency of workers in an industrial environment is related to the quality of light through a chain correlations staggered formers quality, the rate and the final result in the execution of a task.”Better lighting and adapting to the characteristics of man and the working task undoubtedly leads to increased yields and consequently to increased productivity.
a.Optical Performance
The human eye can recognize many more colors and shadows under daylight than,what under artificial daylight fos.To also increases the depth perception and peripheral vision. When employees can see better, perform better.CourResearch in the field have pointed out that improvement in visual performance of an employee can lead to an increase of 7-30% productivity of duty done but also to a decrease of defective products 18-90% (!) depending on the existing system Suntracker state.The use only positive results can echei.Mia properly designed intervention leads to lighting that is suitable for seamless execution of every task, increasing time productive labor and eliminating all the above factors lead to reduced efficiency, errors and quality problems.
b.Visual Comfort
The absence of adequate natural lighting with certainty leads to eyestrain. As a consequence, term, can occur visual acuity workers. Short not, leads to eyestrain (tingling, pain), headaches and lack of appetite for work (how much more so and complaints, tensions etc.. disrupting the work environment). The source of visual fatigue can be found in a number of factors related to the quality of illumination.
Beyond the obvious, which is the smallest of the required luminous intensity, o poor lighting may be due to a direct the eyes of workers fitting system that creates strong reflections, shadows and / or whether the source of glare or reflection of light is directed directly into the eyes of workers.HPIM1941
In no specific tasks and functions to municipalities increased optical requirements, visual fatigue negate the very ability of the employee to adequately perform the task itself. For example, the optical quality control paint surfaces (typical in steel, white goods industries, car etc.), where the task is such that the operator operates the reflections on a surface so that the difference of brightness to reveal surface defects, visual fatigue occurs exponentially with respect to time. In many cases the number of errors increases significantly after 2 just hours and throughout the remainder of the shift, increasing with time. Better quality lighting brings both extension of the production runtime task and substantial improvement of
c.Vigilance, Incentives & Job Satisfaction
The effect of bright daylight to humans and the sense of satisfaction and wellbeing is a general conclusion that occurs inside and outside work. This alone has a direct consequence in the mood for work, on efficiency and motivation that is inside each worker. Additional, no evidence correlating increased arousal by lengthening the time before the occurrence of the fatigue.Untitled-8When the industrial lighting is adequate, alertness of workers is longest, while somnolence are clearly lower, which recommends greater apodotikotita.Telos, The increased lighting has an effect on occupational stress.
Although stress is primarily due to psychological factors, however it has been observed that the simulations luminance summer weather (ie sunshine) may not offset to some extent the observed difference indoors, especially in winter.
Industrial lighting and security
Safety at work and especially in high-risk industries, many accidents could have been avoided, if there was better lighting. For example, a survey conducted in France and sample 81.000 accidents, found that the 1/4 some of these were attributed to poor quality of electric.
Among the main causes of accidents involving artificial lighting, meet:
DIGITAL CAMERA
- Lighting low intensity relative to the requirements of the task at speed and detail in execution
- Bad lighting that leaves „blind spots“
- Bad orientation light leaves shadows, creates reflections or glare, etc..
With the implementation of daylight systems Suntracker, Prevention is profanis.I reduce accidents, as being serious and, automatically lead to reduced absenteeism or downtime in production and maintain a safe working environment that only has a positive impact on employee productivity.
Historical, prevailing practice of factories without windows, as it was seen as an ideal way to ensure the creation of a cleaner, dust-free working environment. The studies showed that the natural light plants can affect the physiological and psychological health of workers in these.
Sweden built the first underground, windowless factory 1946 and found that workers in their factories developed many health problems. There were many complaints related to employee fatigue, headaches, and generally created a strongly negative attitude to the fact lack of natural lighting (Robbins 1986).
Effect on human physiology
Numerous studies showed that in windowless factories presented most cases workers with headaches, Blackouts, and diseases related to plants having windows (Plant 1970). In addition to, the cost of products produced in factories without windows is increased due to the time lost by the poor health of workers
Examination (Hathaway, et al.1992) blood of workers in an underground, windowless factory has demonstrated that there was a relationship between poor health and lack of solar ultraviolet radiation. The study concluded that workers in windowless factories showed increased permeability of the capillaries of the skin, reduced activity of white blood cells, increased and catarrhal infections and colds [compared with workers in factories with windows].
Studies by Trysin in underground factories in Sweden found that lighting levels negatively affect workers (Collins 1975). According to the study, employees will have to take longer periods of rest areas with natural lighting or outdoors.
Psychological health
In his study of work environments without windows 1964, the Pritchard presented the ‚reports on their employees‘ personnel directors, which reported allegations about their health. Workers protesting events claustrophobia symptoms and work-related stress due to the absence of windows in the workplace.
A study involving the examination of blood 100 workers in underground storage, without the presence of natural lighting, showed that over eight years there was no change in normal blood, but found that mental health workers presented sensitive (Collins 1975)
In other findings on the psychological well-being of workers in factories without windows, the FD Hollister found that the conditions were so harmful to the psychology of workers, thereby lead them to a personal quest for solutions to achieve contact with the external environment.. Ο Hollister δήλωσε «… workers broke so many wall panels which became necessary to provide some visual contact with the outside world.” After studying the effect of factories without windows on workers‘ health, these types of plants should be used only in those cases where it is necessary for a cleaner environment.
