Introduction General part

Selection of on-site lighting system.
Natural and artificial lighting of the lighting system for the enterprise is obtained in accordance with the norms of illumination of industrial networks.
The projected section provides natural and artificial lighting.
Natural lighting is done through glass and lanterns, the TEK norm is 0.1-10%. Artificial lighting is carried out by means of gas-discharge lamps. These are fluorescent lamps. Calculations are made using CN and P11-4-79 to ensure normal working conditions.
The calculation based on the luminous flux utilization index showed that the required luminous flux should be F_l = 5220 lm.
The average light required in the department is 300 lk. We find the number of lamps as follows:
Based on hygienic requirements, the size and area of the facility known to one worker is determined. Therefore, each worker is allocated 20 m² of space and 80 m³ of building space under the MMC.
E_n =300 lk –lightening has to be.
S=140 m³-lighting area
K=1,6-coefficient
Here: i=
a is the width and length of the b-prolet. Npr = n-hc-hpm = 8.6-0.1-0.8 = 7.7m - building height;

N= N= lamp
Fluorescent lights are arranged in a checkerboard pattern.
Emergency lighting should be provided to prevent accidents.
Selection of natural lighting, lighting system and natural light coefficient of the projected building according to ChiP11-4-79.
There are lighting fixtures in certain parts of the building for natural light. Illumination is rated by the coefficient of natural illumination. We assume that this coefficient is 0.9 according to ChiP11-4-71.
Here's how to put one together for use with your lighting fixtures.
