Workplace lighting is an important factor in the environment and the work environment. For normal work and human life, lighting, sunlight and light are very important. Conversely, an insufficient level and poor quality of illumination (especially in the process of performing work requiring eye strain) are the causes of visual impairment among workers.
Workplace illumination rate
The main characteristics of illumination are ensured by the proper operation and proper use of safe lighting devices, as well as strict state supervision and control of the implementation of hygiene standards and lighting regulations.
Regulatory requirements for artificial lighting for enterprises were first developed, agreed and approved by Professor P. Tikhodeev in 1928. From that moment, the standard values of illumination were revised repeatedly, while the requirements for the level of illumination at the workplace and for the conditions for performing work related to visual load were mainly increased.
Workplace lighting: main types
To optimize working conditions, three types of lighting are distinguished: artificial (artificial sources of lighting and light), natural (sunlight) and combined (mixed), when insufficient level of natural lighting is supplemented by artificial light. High labor productivity and visual performance of personnel are connected through the rational use of lighting in the production of work.
Workplace lighting: basic requirements
The following requirements must be met for lighting (regardless of the light source):
- lighting at the workplace should be sufficient to provide a comfortable working environment and an optimal level of brightness for the functioning of the vision analyzer;
- ensuring safety during work;
- the uniformity of lighting in space and time should be such that objects and objects that have different reflectivity and brightness can be fully perceived by the organ of vision.
Proper lighting of the workplace
In accordance with hygiene standards for visual work of each type and for the efficient use of electricity, there must be an individual and adjustable source of lighting and light according to certain parameters. This is due to the fact that it is light that provides the receipt and processing of almost 90 percent of all information.
Illumination of the workplace should be non-blind, uniform and sufficient at any time of the day. The most optimal option from the point of view of hygiene is when good illumination of the entire room is combined with intensive illumination of the workplace. The fulfillment of these conditions helps to increase the efficiency of the production process and prevents rapid eye fatigue.
When organizing the lighting of the place of work, you need to make the most of natural light. In the premises of the permanent stay of the staff, general lighting fixtures should be installed so that the light is distributed evenly over the entire area, or directly above each workplace.
Conclusion
Today, an important regularity and main trend in the development of light sources is their improvement, improving reliability, safety, efficiency, efficiency and quality of light transmission. It should be noted the prospect of introducing compact fluorescent lamps with the ability to adjust the level of illumination based on infrared sensors with remote control of light.
