Lighting is an important ergonomic factor. Related to this is the continued growth of installed capacity and consumption of electricity. So saving electricity is an important task in a shortage of energy resources, and gripped our country in recent times. One of the areas for improving energy efficiency is the rationalization of electricity, much of which falls on the light industrial and public premises. Functionality of the visual analyzer depend on the nature of visual activity, the conditions of the work environment, lighting quality and condition linen closet of the analyzer. Over 80% of environmental information is obtained from the visual analyzer, so good lighting helps to increase productivity and reduce accidents. Lighting is divided into natural and artificial: linen closet total - for residential o public buildings; combined - used when the visual task requires a very high naturalness Mr. arabotnata surface and its implementation with general lighting is uneconomic. The combined brightness of the lighting work of general lighting should not be less than 10% of the combined linen closet emission of light, but not less than 150 lx for gazoryazradnite and 50 lx for incandescent lamps. The emission linen closet brightness of lighting prescribed according to the type of work, the contrast, the backlight, and the type of lighting source. To create a favorable light monitor and lighting quality, which depends on the spectrum of light constancy of lighting and more. Lighting systems are one of the most expensive high voltage saorazheniya.Spetsifichnite capital investments are 10-20 times higher compared to the other electric instalattsii. They consume 10-20% of the electricity produced. High requirements placed osvetitelnit systems and different conditions to the three stages of their implementation: design, installation and operation. The first stage - design - largely are essential in terms of quality and efficiency of the lighting system, which is a prerequisite for the release of particular attention at this stage. Engineering design today is a very complex linen closet process that can generally be defined as a purposeful creative activity resulting in creating something new and useful. The design is often accompanied with decision making under certain conditions, which in the case of errors linen closet lead to serious consequences. Informattsiyata available to the designer, it is often too low, and requires the use of computers (COMPUTER). linen closet Topic of this thesis is to develop a lighting system of the sewing industry.
1. Types of lighting systems depending on the principle of the lighting system differ following linen closet systems of lighting - ambient lighting, thereby simultaneously illuminate workplaces and the whole room; - Local lighting consists of lighting, located linen closet in close proximity to the workplace and just illuminating the work surface; - Combined lighting, representing a set of general and local lighting. Depending linen closet on the mode of distribution of the luminaire distinguishes two types of general lighting system - even locally. In general uniform illumination lamps are arranged in rows at an equal distance from each other. The distance linen closet between rows is also the same. Thanks to this arrangement is achieved evenly lighting the entire room. General lighting is equally appropriate to be used in the following cases: a) the premises where the work is performed uniform; b) in the dense industrial machinery and equipment; linen closet when they do not create shadows on jobs; c) administrative offices; d) premises that do not involve strenuous and prolonged visual work; e) processing and adjoining rooms and warehouses. linen closet The main advantage of this system of illumination are: 1. Uniform illumination of the entire space of the room. 2. Limitation of glare permitted in all jobs and positions of the user. The disadvantages are: 1. An appearance of reflected luster due to the large number of lamps arranged in a different manner to jobs and observers. 2. Large installed capacity linen closet and expensive lighting systems, linen closet especially in the implementation of high illumination. In general localized lighting luminaires are unevenly distributed in the room, thereby achieving higher illumination in separate areas of the room. The location of the luminaires is orientated jobs, thanks to which makes it possible to remove shadows on the work surface and direct the appropriate light
