Bakalauro baigiamasis darbas šviečiantis dekoratyvus objektas „220“ sukurtas 2010 m. Darbo tikslas – sukurti šviečiantį objektą atskleidžiant dirbtinės šviesos, meniškumo ir funkcionalumo galimybių sintezę, panaudojant floristines medžiagas. Tikslui pasiekti buvo keliami tokie uždaviniai: išanalizuoti literatūrą pasirinkta tema; suprojektuoti šviečiantį dekoratyvų objektą; išnagrinėti technologinius gaminamo darbo ypatumus; sukurtą objektą pritaikyti pasirinktam interjerui. Lietuvos interjeruose pasigendu savito, išskirtinio apšvietimo, netikėtų, originalių šviestuvų ar šviečiančių objektų parinkimo ir pritaikymo interjere. Europoje šiuo metu sparčiai populiarėja rankų darbo šviestuvai. Į Lietuvą ši mada po truputį ateina. Yra keletas dizainerių, kurie gamina būtent tokius šviestuvus. Tai Dovas Serapinas, Eduardas Bytautas, Laura Keblytė. Manau šią tendenciją vertėtų populiarinti. Tokie daiktai ne tik atlieka savo funkciją, bet ir yra traktuojami kaip meno kūriniai. Atlikus darbą gautos tokios išvados: 1. Nors apšvietimo dizainui dar tik apie 100 metų, jo raida gausi faktais, atradimais, besikeičiančiomis mados tendencijomis. Dabar populiariausi ekologiško dizaino šviečiantys objektai. Inovatyvus ir perspektyvus šviečiantis objektas privalo taupiau naudoti elektros energiją, o jo gamybai panaudotos medžiagos turi natūraliai irti gamtoje. 2. Šiuo metu Lietuvos ir užsienio privačiuose interjeruose dominuoja minimalizmas. Interjerų paletėse populiarios balta, juoda, ruda...

The aim is to create a luminous object combining the synthesis of artificial light, artistic and functional opportunities and using floristic materials. In order to achieve the goal the following objectives have been set: to analyse the literature on the chosen subject, design a luminous decorative object, determine the technological peculiarities, adjust the created object to the interior, prepare theoretical part. Lithuanian interior lacks unique and special lighting, more exactly, there are no surprising, original lights, or luminous objects that can be applied in the interior. At present handmade chandeliers or illuminators become more and more popular in Europe. This fashion is slowly coming to Lithuania too. Some designers who make such chandeliers are Dovas Serapinas, Eduardas Bytautas, Laura Keblytė. I suppose, that this tendency has to be popular in future. The mentioned objects do not onle fulfil their main function, but also are pieces of art. Having performed the work the following conclusions have been set: 1. Light desing is relatively new, just about 100 years, but its development is featured by facts, discoveries, changing fashion trends. At present the most popular are ecological luminous objects. Innovative and perspective luminous object is obliged to use less electricity and its material has to disintegrate or decompose naturally in nature. 2. Recently in foreign... [to full text]

The purpose of this handbook is twofold. First, it is to be used as a guide for maintenance personnel when they have to deal with the lighting system. Whi 1 e the 1 i ghti ng 1 oads are typical of those in any large building, the control functions and equipment operation require some specific information for proper performance. Second, it can be used by the person in charge of scheduling to gain a greater understanding of how the system works. Although a detailed understanding isn't necessary, it is helpful to know what is out there and why it does what it is supposed to do.The reason for the development of this handbook is that with all of the literature produced by the manufacturer there was no single source, or starting point, that explained the whole package. There is a great deal of information in each of the various publications and with this handbook one should easily be able to utilize it. In order to use this book most effectively one should have the manufacturer's documents on hand for reference as they are referred to frequently. In addition the flow charts enhance one's ability "to know where you are” when using the terminal for data entry. / Department of Architecture

This study presents a look at the development of residential lighting in America and the technological and social factors which inspired the development. Availability of fuels, quality of light provided, daily care needed by a light source, and safety were all direct influences on the development of artificial lighting. Technological advances in response to the social needs began with the closed font and continued through the removable burner, accommodating a variety of fuels including tallow, lard, whale oil, burning fluids, kerosene, gas and ultimately electricity. Along with the increasing illuminating power, the amount of decoration, both possible and accepted, increased. / Department of Architecture

A amostra do estudo transversal foi definida aleatoriamente, com a participacao de mulheres voluntarias. Foram selecionados tres grupos com dez participantes em cada: lojas de rua com contato com exterior e turno de trabalho diurno (9h as18h), lojas de shopping centers sem janelas para o exterior com turno de trabalho diurno (10h as 18h) e lojas de shopping centers sem janelas para o exterior com turno de trabalho tarde e noite (14h as 22h). A avaliacao da iluminacao considerou as dimensoes das lojas e caracteristicas dos sistemas, incluindo ofuscamento, aparencia de cor da luz, flexibilidade e possibilidade de controles da iluminacao pelas funcionarias. A avaliacao de aspectos relativos a saude e ao bem-estar utilizou como instrumentos as escalas psicometricas validadas pela area da Psicologia para afericao de sintomas depressivos, de ansiedade e estresse. A avaliacao das condicoes de sono e analise do ritmo atividade/repouso foi feita com um actimetro com luximetro acoplado (Actiwatch), e a analise do ritmo de temperatura corporal, com um sensor de temperatura (Ibutton). Foi estabelecido o padrao de luz 24h a que esteve sujeita cada participante durante cinco dias consecutivos e verificada a influencia deste padrao no sistema circadiano, atraves da medicao dos niveis de melatonina e cortisol salivar. O grau de satisfacao das funcionarias e suas preferencias relativas a iluminacao do ambiente de trabalho foram levantados atraves da aplicacao de questionarios. Os dados foram analisados utilizando-se correlacoes de Pearson, ANOVA e regressoes tipo stepwise, tendo como ferramenta o SPSS for Windows 13.0. No grupo das lojas de rua, os resultados indicam que, apesar de o nivel de satisfacao das funcionarias com os sistemas de iluminacao nao ser elevado, a presenca de luz natural contribui para sua saude e bem-estar. O cruzamento de aspectos de satisfacao e emocionais com os aspectos biologicos indicou que quanto maior a satisfacao geral com a iluminacao pela funcionaria da loja de rua, maior o nivel de melatonina as 24h e menores o escores de depressao. A possibilidade de contato com o exterior neste grupo leva a melhores condicoes fisiologicas, principalmente nas condicoes de sono, que os demais grupos. Nos grupos de shopping centers, a correlacao inversa encontrada entre a iluminancia geral media da loja e a satisfacao geral com as condicoes da iluminacao no ambiente de trabalho merece destaque, porque e nesta categoria que os escores foram mais altos em todas as escalas aplicadas, indicando piores condicoes emocionais, e onde ha alteracoes nos aspectos biologicos avaliados. A pesquisa conclui ser necessaria a revisao das estrategias para a iluminacao de lojas, sejam elas de rua ou de shopping centers, buscando-se resolver os possiveis conflitos entre uma iluminacao para vender produtos e a que considere a loja como um ambiente de trabalho. / Abstract: This work addresses the issue of non-visual impacts of human exposure to light, in an attempt to relate the quality of lighting to health, comfort, and well-being of female retail store employees. The sample for the cross-sectional study was randomly established with female volunteers. Three groups were selected: street retail stores with outside contact and daily working hours (9 a.m. to 6 p.m.), shopping mall retail stores with no window facing outside, with daily working hours (10 a.m. to 6 p.m.), and shopping mall retail stores with no window facing outside, with afternoon and evening working hours (2 p.m. to 10 p.m.). Each group included ten employees. Assessment of lighting considered the dimensions of the stores and characteristics of systems, including the occurrence of glare, color appearance of light, flexibility, and possibility of lighting control by employees. The tools to assess well-being and health were psychometric scales internationally validated by the psychiatric field to measure depression, anxiety, and stress symptoms. Assessment of sleep conditions and analysis of the activity/rest rhythm was carried by a wrist monitor with attached luximeter (Actiwatch) and the analysis of the body temperature rhythm was made by a temperature sensor (Ibutton), to which each participant was submitted for five consecutive days. The lighting pattern's influence on the circadian system was verified by measuring saliva melatonin and cortisol levels. The degree of satisfaction of employees and their preferences regarding work environment lighting were surveyed by applying questionnaires. Data were analyzed using Pearson correlations, ANOVA, and stepwise regression, with the tool SPSS for Windows 13.0. In street retail store group, results indicate that even though employees' satisfaction with lighting systems is not high, the presence of natural light contributes for their health and well-being. Crossing the assessment of satisfaction and emotional aspects with biological ones indicated that the higher the street retail store employees' general satisfaction with lighting, the higher their melatonin level at 12 p.m. and the lower their depression scores. Possibility of outside visual contact in that group leads to better physiological conditions, especially sleep conditions, than the other groups. In shopping mall groups, the reverse correlation found between the store's average general illuminance and general satisfaction with lighting conditions in the work environment is worth pointing out, since scores were highest in that category (worse emotional conditions) in all scales applied and there are changes both in cortisol rhythm (tendency to lower rhythm in the morning and afternoon mall group) and in melatonin (tendency to phase delay in the afternoon and evening mall group) as well as differentiation in activity rhythm and temperature in the afternoon and evening mall group. Shopping mall employees' miss visual contact with the outside, being able to vary lighting during the workday, and consider lighting as excessive. Most of them reported that they would like to reduce the amount of light in their workplace during the day. The study concludes that it is necessary to review the stores' lighting strategies, whether they are street retail stores or shopping mall retail stores, to seek new guidelines able to solve the possible conflicts between light oriented to sell products and that which considers the store as a workplace. / Doutorado / Arquitetura e Construção / Doutor em Engenharia Civil

Store lighting is a combination of art form and function that contributes to a retail store's sales and prosperity. The quantity, quality, and effect of the light reaching the merchandise are the determining factors in the success of the sale of merchandise. There are three basic merchandise lighting techniques used in retail stores. They include the low-end, mid-market, and high-end lighting techniques. However, retailers are developing merchandising techniques that do not have a clear cut lighting solution. A new merchandising technique for the audio/video retailer is the simulated home environment (SHE). It is a series of rooms and vignettes that present audio/video products in a home setting. Studies have shown that lighting has an affect on human behavior. In a retail store, three customer behaviors are linked to increased sales: customer communication with store personnel; customer interaction with displays and merchandise; and length of time in the store. The purpose of this study was to determine which of the lighting techniques was most effective in stimulating the customer behaviors linked to increased sales in an audio/video store's SHE. The study was conducted in an audio/video store's SHE equipped with a lighting system that could produce the three lighting techniques. Each day the SHE's lighting system was set up for one of the lighting techniques and customer behavior was unobtrusively observed and recorded. A convenience method of sampling was used in the study. The subjects were the customers shopping in the SHE. The study's experiment was done twice using two methods for selecting the observation days for the experiments. One method used the same day of the week in three successive weeks (SDW), the other used three different days within the same week (DDW). The sample size for the SDW method was 123, and 47 for the DDW method. To assess the effectiveness of the lighting techniques in stimulating customer behavior, two behavior rating scales were created. The Customer Communication Rating Scale and the Customer Display and Merchandise Interaction Rating Scale assigned values to observed customer behavior. The third customer behavior, length of time in the SHE, was measured in minutes. Data was analyzed using Chi Square tests for the Customer Communication Rating Scale and the Customer Display and Merchandise Interaction Rating Scale. An ANOVA was used to analyze the length of time in the SHE. The results indicated that both the mid-market and high-end lighting techniques were significantly better than the low-end lighting technique in stimulating customer display and merchandise interaction, and longer customer visits in the SHE. However, the results indicated that all three lighting techniques were equally effective at stimulating customer communication with store personnel. The study concluded that store lighting designs that include highlighting of displays and merchandise will stimulate customer display and merchandise interaction and longer customer visits. / Master of Science
