The meaning of DIRECT LIGHTING is lighting in which the greater part of the light goes directly from the source to the area lit.
Lighting devices and methods for providing daylight to the interior of a structure are disclosed. Some embodiments disclosed herein provide a daylighting device including a tube having a sidewall with a reflective interior surface, a light collecting structure, and a light reflector positioned to ...
High-light-grown leaves with multiple palisade layers may be adapted to better utilize direct than diffuse light, while shade leaf structure does not appear to discriminate light based on its directionality. Based upon our measurements, it appears that leaf-level and canopy-level photosynthetic ...
The paper describes new improvements in S, a set of numerical models for the simulation of natural light in both the urban morphologies and the indoor architectural spaces which is developed in our laboratory. This tool takes into account the direct solar and the diffuse sky luminous energies for...
i.e. Lambertian reflectance. A surface built from a non-absorbing powder such asplaster, or from fibres such as paper, or from apolycrystalline materialsuch as white marble, reflects light diffusely with great efficiency. Many common materials exhibit a mixture of specular anddiffuse reflection. ...
This paper presents the latest versions of several models developed by the authors to predict short time-step solar energy and daylight availability quantities needed by energy system modelers or building designers. The modeled quantities are global, direct and diffuse daylight illuminance, diffuse irradi...
Observation of direct sunlight,diffuse sunlight through cloud and its many variations will develop this understanding.A spotlight or direct flash imitates the type of light we see from direct sunlight,a hard light with strong shadows and extreme contrast.A floodlight/soft box imitates the type of ...
Additionally, a polygon's material has properties that affect how that polygon reflects the light it receives. You set a single reflectance trait that describes how the material reflects ambient light, and you set individual traits to determine the material's specular and diffuse reflectance. For ...
undergoing oxidation and reducing the electron transport chain. The electron ejected from P680 of PSII ultimately reduces a molecule of the lipid plastoquinone (PQ). When doubly reduced with two electrons and two protons, the resulting PQH2 debinds from PSII, diffuses to and reduces the ...
Light diffusion material with color temperature correction The invention relates to a light diffuser comprising a polymeric film incorporating microvoids wherein the film has a diffuse light transmission efficiency of at least 65% at 500 nm and wherein the microvoids are of a size, shape and fre...
