Lighting knowledge | light transmission is what kind of situation? - China lighting network

When light is incident to the transparent or translucent material surface, part of the reflection, one part is absorbed, and part can be transmitted in the past. Due to the variety of different transmission materials, and transmitted light in spatial distribution rules of the form is divided into three types of transmission, diffuse transmission and hybrid transmission. ( 1) Rules of transmission when the light on the transparent material, transmission light is carried out in accordance with the laws of geometrical optics directional strong directional transmission, this is the rules of transmission. ( 2) Diffuse transmission of light through the rough surface transmission materials ( Such as ground glass) , the transmitted light dispersion, there is no rule on macro transmission, called diffuse transmission. If the light to diffuse sexual good pervious to light material, Such as milky white glass, etc. ) , the transmitted light will be scattered in all directions and evenly distributed throughout the hemisphere space, the brightness in homogeneous in all directions at the same time, this is known as isotropic diffuse transmission ( Formerly known as uniform diffuse transmission) 。 ( 3) Combined transmission light transmission material, its transmission performance between rules through and diffuse transmission ( Or bulk transmission) Between the situation, called hybrid transmission. When the light reaches the glass curtain wall surface reflection and transmission at the same time when two physical reaction. YanZhiXiang
