The lighting of the workplace is an important factorenvironment and production environment. For normal work and life of a person, lighting, sunlight and light are very important. Conversely, insufficient level and low quality of illumination (especially in the process of performing works that require visual strain) are the causes of visual impairment among workers.
The norm of illumination of the workplace
Main characteristics of illuminationare ensured by the proper operation and proper use of safe lighting devices, as well as by strict state supervision and monitoring of the implementation of hygienic norms and lighting regulations.
Normative requirements for artificial lightingfor the enterprises for the first time have been developed, coordinated and approved by professor PM Tikhodeev in 1928. Since that time, the normative magnitudes of illumination have been reviewed many times, while the requirements to the level of illumination at the workplace and to the conditions for performing work related to visual loading have been generally increased.
Workplace lighting: the main types
To optimize working conditions, there are three typeslighting: artificial (artificial light and light sources), natural (sunlight) and combined (mixed), when the insufficient level of natural light is supplemented by artificial light. High labor productivity and visual performance of personnel are linked through the rational use of lighting in the production of works.
Workplace lighting: basic requirements
For lighting (regardless of the light source), the following requirements must be met:
- lighting in the workplace should be sufficient to provide comfortable working conditions and an optimum level of brightness for the functioning of the vision analyzer;
- ensuring safety during production;
- uniformity of illumination in space and intime should be such that objects and objects that have different reflectivity and brightness can be fully perceived by the organ of vision.
Correct lighting of the workplace
In accordance with the hygienic standards forvisual works of each kind and for the effective use of electricity there must be an individual and regulated by certain parameters the source of lighting and light. This is due to the fact that it is the light that ensures the receipt and processing of almost 90 percent of all information.
Workplace lighting should not be dazzlingeyes, uniform and sufficient at any time of day. The most optimal option in terms of hygiene - when the good illumination of the whole room is combined with intensive lighting of the workplace. The fulfillment of these conditions increases the efficiency of the production process and prevents rapid eye fatigue.
When organizing workplace lightingmake the most of natural light. In the permanent residence of personnel, general lighting should be installed so that light throughout the area is distributed evenly, or directly above each workplace.
To date, an important regularity andthe main trend of light sources development is their improvement, increase of reliability, safety, economy, efficiency and quality of light transmission. It should be noted the prospect of introducing compact fluorescent lamps with the possibility of adjusting the level of illumination based on infrared sensors with remote light control.
