Lighting can be better integrated to the architectural design process through computational tools that are capable enough to visualize and analyze the luminous environment accurately. This paper describes an image-based lighting analysis procedure that operates with high dynamic range lighting data for evaluating architectural spaces. The discussions mainly refer to visual and metrological aspe...

By the rise of concerns for global warming, reducing emissions via lowering energy consumption has become a necessity in every sector and the lighting sector is no exception. However, it should not come at the cost of lighting quality and user comfort which is a common practice in today’s lighting design and energy reduction initiatives. The “energy reduction” view should change toward “value d...

As LED lighting technology becomes omnipresent, lighting environments become more advanced and allow for adjusting various parameters such as color, brightness, and saturation. This poses challenges for interaction design, particularly when lighting environments are shared between multiple users. This paper presents “Vuur”: a shared physical interface with which users can control lighting in me...

This paper presents a design for intelligent control system of scene adaptive semiconductor lighting. The new design contains the host computer and the terminal in a control network. The lighting effect patterns are edited by the software on the host computer, then the lighting scene data is transported to the terminal through network. The terminal is a sub-controller based on the embedded syst...

This study was conducted to determine the effects of increasing lighting after peak production on eggs production and Hatchable Eggs in broiler breeder Hubbard F15. In this research we used from 4 growing saloons, that in per saloons were 5250 Hubbards broiler breeder hens. In this Experiment we used by Line design way of GLM for analysed data, that we considered the Effects of two parameters, ...

We present a framework for interactive lighting design based on linear re-rendering. The rendering operation is linear with respect to light sources, assuming a xed scene and camera geometry. This linearity means that a scene may be interactively re-rendered via linear combination of a set of basis images, each rendered under a particular basis light. We focus on choosing and designing a suitab...

A proper professional lighting design implies in a continuous search for the best compromise between both low power consumption and better lighting quality. This search converts this design into a hard to solve multi-objective optimization problem. Evolutionary algorithms are widely used to attack that type of hard optimization problems. However, professionals could not benefit from that kind o...
