The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

Lumilos is a work investigating the possibilities to use light and color in an interactive design context. I have explored different light sources and compared them to each other and given a short description of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms. I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations.

The modern auditor is, because of an increased complexity, dependent on the use of experts. Simultaneously different scandals have occurred where the auditor in fact have been using experts. Although the auditor is using an expert, the auditor alone is responsible for the statement that the expert makes. Research simultaneously indicates that the auditor?s use of experts is a difficult task.

Inspired by how to sketch a light cone from a flashlight in a comic I wanted to create an armature carried only by its own light cone. To manage this challenge I sketched in an architectural and sculptural way, where I chose to ignore the function of the lamp as long as possible.As a result I developed an armature with a stunning shape, with an illusion that it was carried by its own light cone. It could be hanged on a wall, placed on a table, pushed against a ceiling or standing on the floor.Depending of its size the light cone from the light source lightens up the surface and draws attention to the otherwise forgotten wallpaper or the undisposed statue in the darkness of the city..

The animal welfare act in Sweden states that dairy cows need to have at least a dim light present at night, but there are no recommendations for what intensity the light should have. It is unknown how cows perceive and react to low light intensities and earlier studies on this topic are limited. Red light as night light has also been suggested, based on the cows? inability to perceive red light. This have however been questioned. The aim with this study was to investigate how four different light intensities affect dairy cows behavior.

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

In this study, we investigate various lighting applications in a virtual environment, where we compare between light based in naturalism (natural light) and pictorialism (artistic light). The purpose of this study is to gain further knowledge in lighting, which is increasingly important for game graphics. Theory are examined to gather information and recommendations on how to use various light settings that convey different emotions. We then use this information to illuminate the environment that we have built. The environment is presented in Unreal 4 for respondents who are allowed to move around freely in the environment.

The relation between the cave and the circumpolar light conditions has long been a part of the interpretation of the meaning of the Norwegian cave art. This paper explores the relationship by trading the concept of a sensory dichotomy between light and darkness for that of a perceptual relationship between the paintings, the environment and the light..

This work is an exploration of a method and how to find balance between it and its contents. One part consists of a technical study on how to use UV light to yellow distinct surfaces on paper and the other is about how to find use of the method. The common denominator is determined as the consequence of the relationship between light and time. The result is three images that shows various traces of time with time as a graphic expression..

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

The essay aimed to investigate whether people choose light products or original products regarding dairy products and beverages as well as the motives for their respective choice. Finally the purpose was to find out where they had obtained the knowledge to make their choice and how they thought media had affected their choice. The method used was a qualitative decsriptive study with three focus groups consisting of six women aged 40-50, six women aged 20-30 and four men aged 25-35. Each interview lasted 2 hours. The groups were a selection of comfort.   The results showed that all respondents choose original products. The primary reason was because they thought that original products tasted better and had a better consistence.

Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

This report describes a project carried out in cooperation with Klippan Safety AB. The purpose of this project has been to develop a product that facilitates the living area in a truck cabin for the customers. To be able to develop, in a structured way, that kind of product, the project has been based on different product development theories. The project contained of following parts: marketing research, product generation, product evaluation and prototyping. After information from the marketing research and discussions with the company, the decision was made that the task was going to consist an improvement of the existing product referred to as 'the comfort module'.

Bright Chest of DrawersThis project derives from a fascination of spaces which withonly light and shadow withhold a narrative value, which createsemotions and experiences with a minimum of objects. Iwanted to invesitigate light and lighting, and create a productthat can change the mood and experience of a spatial enviromentwith light. Questions I asked myself was: How do I relateto the spatial limitations that arise? How can I, with light asmy tool, give form to an immaterial value or state of mind?Will the object that illuminates be the most important factorof communication and meaning when I want to tell a story, oris it the light itself?The result became a chest of drawers that is lighted up frominside when you open the drawers. It serves a function as a unitfor storage of objects, but also makes us reflect of the importanceof objects, of how we define a spatial enviroment, andwhat we consider as private spaces in our home..
