A summary of the discussion of technical lighting for students of art Author: Hi - Wednesday, Persian date Farvardin 10, 1390
Technical lighting - the amount of light in all directions from a light source, the light emitted per second (optical power) business spotlight say. - The light show with Φ. Single optical flow lumen (Lm) is. - The amount of light that is emitted per unit area is called brightness. Dimmer unit luxury (LX) or lumens per meter square. = One lumen per square meter is a luxury. - The brightness with the letter E indicates that the formula business spotlight is - towards the light (optical power) to be used electric lamp lumens per watt light bulb and it is called. - The light flux density business spotlight in space called a light intensity. And a single candle or candela (ca) is. - The surface of the light intensity of the emitted light is called brightness. Cm is the brightness of a candle - light scattering techniques are carried out according to the following table.
40 to 60%
Drilling and milling
- To select the type of lighting to three factors: economic issues, beauty, health OBSERVED. The economic issues between the initial cost and maintenance costs should be considered. - Interior lighting calculation steps: First, the intensity of the standard tables in terms of luxury and obtains business spotlight the required location. Select the type of lighting and light as we choose. Using tables for each light pollution factor (MF) to gain. Using the formula we calculate the coefficient space.
Lighting for direct, indirect and semi-direct and indirect-uniform illumination half
W: the width L: the length H: height of the lights
And then calculated the amount of light a lamp / light amount of light necessary to obtain the total number of lights.
