Lambertian surface: uniform diffuse reflection

4. November 2007

Returning to the subject matter on Oct. 14 on the properties of the materials I would like to deepen the theme perfectly diffusing surface and then describe the characteristics and behavior, they also take this opportunity to introduce a very important report which links the Luminance and Illuminance of a Lambertian surface: PI or the law of Lambert law.
As already mentioned, the [...]

Materials: specular and diffuse

14. October 2007

In this article I describe the relationship between the physical characteristics of a material and the behavior of light impinging on it, especially the specular and diffuse.
The materials can be distinguished by opaque and translucent, semitransparent be noted that the term is given as if a beam of light [...]

At the beginning of September, coinciding with the end of summer, here is a nice demonstration, perhaps it would be appropriate to look at previous articles which have defined the fundamental values of lighting: A bit 'technique # 2: illuminance and luminance and candles lumens: intensity and luminous flux.
Better known as Law [...]

Control glare - UGR (Unified Glare Rating)

C 'is a bit' of confusion on the issue dell'UGR. He feels that the UGR must be less than 19, a little 'is known as the lux on a table should be 500. I doubt that anyone who engages in these disquisitions technical know exactly what he is talking about.
Here is an [...]

A little 'Technique # 2: Illuminance and Luminance

9. July 2007

In the previous article I described the two basic values of lighting: the intensity and luminous flux. Next step is the quantitative definition of light that affects or is emitted from a surface.
There are two sizes qunatitative: illuminance and luminance.
The illumination is a quantity independent of the objective position of the surface observer, measuring [...]

$Candela and Lumen: intensity and luminous flux$

And here by popular demand a nice technical unit on basic lighting. in this article I will try to give some 'basics of lighting, especially the definitions of intensity and luminous flux, lighting concepts necessary for newbies (and not). Especially necessary to introduce a series of articles [...]
