For enclosed spaces and landscaping, the size of each home checkers 3 to 10 m depending on the size

Impudence and damage to the retina
The following factors, in addition to eye health is vital implemented objects and images:
The results of the 320 light industrial workshop of 20 workers in the industrial zone 7 (Tehran, Mashhad, Qazvin, Tehran, Tonkabon, Zanjan, Qom), in which the number of 17,829 workers have found that only 5424 people working at 4 / 30% of working environments have a favorable light.
1. The flux of light source:
In practice, one candela intensity of light from a light source to the surface (1/60) cm2 of a black body at the melting point of platinum (2045 k) at atmospheric pressure (101325 Pa) is. The intensity of the light source are as standard candles.
The required intensity Lx
And recognition of objects implemented in the twilight least cd / m2 01/0 is the brightness. The higher brightness cd / m2 3 is hardly possible to distinguish color and brightness than cd / m23 high visibility colors Shvd.drkhshndgy easy cd / m2 100 may cause eye fatigue, or cause annoyance observer,
To determine the rate of conversion of electrical energy into light energy than purely an electric lamp is ideal for gain. The definition of 680 lumens per watt gain is considered ideal light bulb.
1. If the light sources are not limited to, any observer can be radiated in all directions from the light source away from the intensity reduced. Associated with changes in intensity in proportion to the distance, inverse-square law is true. The following equation is true for any distance r from a point source:
2. If the light radiation florian schulz on a horizontal surface at points considered the radiation angle relative to a line perpendicular to the surface in the case of illumination at each point on the surface horizon intensity of the light source, up to the point of the distance between the source of and cosine angle relative to a line perpendicular to the surface:
3. If the light radiation on vertical surfaces in areas considered to radiation at an angle relative to a line perpendicular to the surface. In this case the intensity of light illumination in the surface of the horizon the source, florian schulz the distance florian schulz between the point of the source, the sinus angle relative to the vertical surface.
Natural Lighting Design Principles (continued)
Sun priority natural resource is used in places with high depth or at inappropriate times of the possibility of using solar lighting is limited and sometimes impossible, it can be of the technical and use of the resources technical design Roshanaei enough electrical and satisfactorily fulfilled.
Lights features:
Technical characteristics of lights to choose them according to place of use is important. Lighting Design is always the responsibility of selecting the best light. The technical characteristics florian schulz of the lighting design consideration include the following:
Lights in the general florian schulz category includes point and linear
For various reasons, all luminous flux produced by the LED light will not use the site. Coefficient florian schulz of utilization ratio of luminous florian schulz flux practical expression CU LED lights on the nominal flux. Several factors affect the interest lights:
The design of artificial lighting inside
Methods of measurement and evaluation
Precisely measuring the position of the workers and the workers should be seen in the workbench if the lighting desk, and the distance exact measurement of the angle should be measured at the working observe If there is a penumbral or other factors considered identical conditions.
For enclosed spaces and landscaping, the size of each home checkers 3 to 10 m depending on the size of the place, to be determined. For example, the length and width of 35 to 15 meters, florian schulz a total of 21 houses regularly checked the dimensions of 5 5 m two. In small places, house size should be less than 3 3 m.
Illuminating Engineering Society of North America, the proposed models are based on the weight of the samples was measured intensities of light in places that are statistically significant, the values measured on the values of sites cluster florian schulz lights in the measured pattern of average of Roshanaei layout been considered. In these models, even for large areas, up to 18 measurement stations is sufficient to determine the average intensity. Interestingly, both the minimum and maximum intensity of it.
4. The magnitude of the coefficient of reflection and inner surfaces so that employees would not hurt.
