Compte tenu des évolutions technologiques et réglementaires actuelles, l’apparition de la technologie LED décuple lespossibilités de conception d’environnements lumineux adaptés aux attentes et besoins des usagers. Bien qu’ingénieurs etarchitectes accordent une importance croissante à la qualité de l’éclairage, peu d’éléments fondamentaux de l’environnementlumineux ont été scientifiquement identifiés au regard des attentes des clients dans le secteur de l’hôtellerie.Dans ce contexte, notre projet de recherche vise à mieux comprendre la perception des environnements lumineux de chambresd’hôtel du point de vue de l’usager, le client de l’hôtel lui-même. Nous faisons l’hypothèse que l’évaluation d’un environnementlumineux dépend à la fois des caractéristiques physiques de l’éclairage, de la situation dans laquelle il est perçu ainsi que descaractéristiques individuelles des usagers qui le perçoivent.Une méthodologie en trois phases a été construite pour tester cette hypothèse et accéder au jugement d’appréciation desusagers d’une chambre d’hôtel en situation réelle. La première phase de ce programme de recherche a permis de mettre enévidence l’importance que le client accorde à la lumière en fonction des situations d’usage qui ponctuent son séjour à l’hôtel,telles que la situation de détente ou de travail. La deuxième phase du programme a conduit à la sélection des paramètres del’éclairage pertinents dans la conception d’environnements lumineux de chambres d’hôtel, fondée sur les préférences de laclientèle. La troisième et dernière phase a permis de mesurer l’influence de la situation d’usage sur l’évaluation desenvironnements lumineux variables en termes de niveaux de lumière (30% et 100% du flux) et de températures de couleur(2700 K, 4200 K).Les résultats de cette étude ont montré que les environnements lumineux préférés des usagers sont caractérisés par une teintechaude et une faible quantité de lumière lors d’une situation de détente, contrairement à une situation de travail où une teintechaude et une forte quantité de lumière des environnements lumineux sont préférées. Des différences dans les caractéristiquesindividuelles, telles que le genre et l’âge, modulent les jugements d’appréciation.De plus, notre projet de recherche porte un enjeu méthodologique, celui de la construction d’un dispositif expérimentalpermettant la formulation et le recueil du jugement d’appréciation des usagers, relatif à l’environnement lumineux d’unechambre d’hôtel dans un contexte écologique. / Given the current changes in technologies and regulations, the emergence of LED technology multiplies the possibilities ofdesigning indoor and outdoor luminous environments adaptable to user’s needs and expectations. Although engineers andarchitects care about lighting quality, few fundamental elements of luminous environments have been evidenced as importantregarding customers’ expectations in the hospitality.In this context, our thesis aimed at better understanding the perception of light environments in hotel rooms from a users’perspective, the hotel customer itself. We assumed that the judgment of appreciation of a luminous environment depended onits lighting parameters, but also the situation during which the luminous environment was perceived and the individualcharacteristics of the users who perceived it.A three-step methodology was designed to test this hypothesis and to retrieve the judgment of appreciation of the users undera real situation in a hotel room. The first phase of this research program highlighted the importance attached by customers tolight depending on the activities undertaken during his/her stay, such as a situation of leisure or a situation of work. The secondenabled the selection of the relevant lighting parameters to design a luminous environment in a hotel room based oncustomers’ preferences. The third phase was set out to measure the influence of the situation on the assessment ofappreciation of luminous environments varying in terms of illuminance (30% of luminous flux vs 100%) and color temperature(2700K, 4200K).Overall, the users preferred the luminous environment characterized by warm white and dim light while relaxing, whereas theypreferred a warm white and bright light when working. Differences in individual characteristics like age and gender influencedthe assessment of appreciation.Moreover, the methodological issue of our project was to develop an experimental device allowing the formulation and thecollection of the users’ assessments of appreciation regarding luminous environments in a hotel room under an ecologicalcontext.

There is increasingly demand for automatic enhancement methods to carry out monitoring of fauna and flora intensive rivers, as well as for the maintenance of pipelines and underwater cables. The enhancement methods specified, developed and validated for using in the rivers of the Amazonia are faced with the problem of imaging quality. The research related to underwater am environments of the Amazon has to dead with high turbidity of the water, caused mainly due to particles in suspension and interaction of light with the environment. The underwater images extraction with satisfiable visibility of the environments of Amazonian rivers has become extremely indispensable and relevant, given that there are natural treasures still unexplored into the depths of these rivers, as well as there is need to maintain the underwater part of the transportation system gas LPG (Liquefied Petroleum Gas) Coari-Manaus. Given this promising scenario, this study aims to improve these images by applying techniques of enhancement using nonlinear filters, which promote the minimization of the light interaction characteristics with the environment, loss of contrast and color in images extracted from turbid underwater environments. The method was experimentally validated with images acquired from simulations of underwater scenes and images acquired in outdoor underwater environments. The proposed method is compared to two other techniques of highlighting or enhancement of images. As in this study, these techniques also require a single image as input. The results return images with enhanced visual quality, considering a large set of experiments with simulation data and real outdoors scenes. / O realce de imagens subaquáticas em aplicações na região dos rios amazônicos é cada vez mais requisitado e carece de um estudo mais aprofundado especialmente nos casos em que os rios apresentam alto índice de turbidez e baixa luminosidade. Estes rios têm demandado cada vez mais métodos de realce automáticos que realizem o monitoramento de sua fauna e flora, bem como manutenção de dutos e cabos subaquáticos. Os métodos de realce especificados, desenvolvidos e validados para uso nos rios da região, se deparam com o problema da qualidade de captação de imagens. As pesquisas relacionadas aos ambientes subaquáticos da Amazônia são prejudicadas pelo alto nível de turbidez de suas águas, causadas principalmente devido às partículas em suspensão e à interação da luz com o meio. A extração de imagens subaquáticas de visibilidade adequada aos ambientes dos rios amazônicos em geral, tem se demonstrado imprescindível e relevante, haja vista que, existem tesouros naturais ainda inexplorados nas profundezas desses rios. Por outro lado, verifica-se a necessidade de manutenção da parte subaquática do sistema de transporte de gás GLP (Gás Liquefeito de Petróleo) Coari-Manaus. Diante deste cenário promissor, este trabalho objetiva a melhoria dessas imagens através da aplicação de técnicas de realce com uso de filtros não lineares, que promovam a minimização das características da interação da luz com o meio, perda de contraste e cores em imagens extraídas de ambientes subaquáticos turvos. O método proposto é comparado a duas outras técnicas de realce ou melhoria de imagens que, como neste trabalho, também requerem uma única imagem como entrada. Os resultados obtidos retornam imagens com melhor qualidade visual, considerando-se um grande conjunto de experimentos realizados com dados de simulação e cenas reais obtidas em ambientes externos.

[pt] À medida que a população cresce, mais alimentos precisarão ser produzidos nas próximas quatro décadas do que nos últimos 10.000 anos. No entanto, o mundo moderno ainda depende da produção de monoculturas de alto rendimento, cada vez mais ameaçada por condições climáticas incomuns, escassez de água e terra insuficiente. A fim de superar esses problemas e alimentar o mundo, é necessário um caminho prático para fornecer alimentos frescos, com qualidade e em escala, com mínima dependência do clima e com uso de água e pegada de carbono reduzidos. Uma abordagem razoável é construir fazendas verticais dentro das cidades em um ambiente fechado repleto de sensores e iluminação artificial controlada por software para uma produção e gestão eficiente do plantio de alimentos. Esta tese propõe a instanciação de um modelo, chamado Ciclo do Software dos Lugares (SoPC), que é capaz de responder a estímulos ambientais em um sistema fechado de produção de plantas com iluminação artificial que possibilite a criação de ambientes com auto-aprendizagem. Esta tese descreve o SoPC, as abordagens e processos de implementação de uma mini fábrica de plantas com iluminação artificial com base na discussão em cinco ciclos de pesquisa-ação. / [en] As the population grows, more food will need to be produced in the next four decades than has been in the past 10,000 years. However, the modern world still depends on high yield monoculture production which is increasingly threatened by unusual weather, water shortages, and insufficient land. In order to overcome these problems and feed the world, a practical path to provide quality fresh healthy food at scale with minimal weather dependency, water usage and reduced carbon footprint is necessary. One reasonable approach is to build vertical farms inside the cities in a close environment full of sensors and artificial lighting controlled by software for efficient production of food crops. This thesis proposes a model, entitled Software of Places Cycle (SoPC), that should be able to answer to environmental stimuli in a closed plant production system using artificial lighting in order to create a self-learning environment. This thesis describes the SoPC, the approaches and processes of implementing a mini Plant Factory using Artificial Lighting based on the discussion on five action-research cycles. The thesis main contribution is a conceptual model to guide the development and maintenance of a mini-PFAL (m-PFAL), a minor contribution is the deployment of the SoP, i.e., the very notion of having software dedicated to a specific place.

The focus of this thesis is to explore the automation technology used in the modern entertainment industry. Upon completion of my thesis, I will deliver a working prototype of the chosen technology and present its capabilities in a choreographed show.

On peut atteindre des images réalistes par la simulation du transport lumineuse avec des méthodes de Monte-Carlo. La possibilité d’utiliser des sources de lumière réalistes pour synthétiser les images contribue grandement à leur réalisme physique. Parmi les modèles existants, ceux basés sur des cartes d’environnement ou des champs lumineuse sont attrayants en raison de leur capacité à capter fidèlement les effets de champs lointain et de champs proche, aussi bien que leur possibilité d’être acquis directement. Parce que ces sources lumineuses acquises ont des fréquences arbitraires et sont éventuellement de grande dimension (4D), leur utilisation pour un rendu réaliste conduit à des problèmes de performance.Dans ce manuscrit, je me concentre sur la façon d’équilibrer la précision de la représentation et de l’efficacité de la simulation. Mon travail repose sur la génération des échantillons de haute qualité à partir des sources de lumière par des estimateurs de Monte-Carlo non-biaisés. Dans ce manuscrit, nous présentons trois nouvelles méthodes.La première consiste à générer des échantillons de haute qualité de manière efficace à partir de cartes d’environnement dynamiques (i.e. qui changent au cours du temps). Nous y parvenons en adoptant une approche GPU qui génère des échantillons de lumière grâce à une approximation du facteur de forme et qui combine ces échantillons avec ceux issus de la BRDF pour chaque pixel d’une image. Notre méthode est précise et efficace. En effet, avec seulement 256 échantillons par pixel, nous obtenons des résultats de haute qualité en temps réel pour une résolution de 1024 × 768. La seconde est une stratégie d’échantillonnage adaptatif pour des sources représente comme un "light field". Nous générons des échantillons de haute qualité de manière efficace en limitant de manière conservative la zone d’échantillonnage sans réduire la précision. Avec une mise en oeuvre sur GPU et sans aucun calcul de visibilité, nous obtenons des résultats de haute qualité avec 200 échantillons pour chaque pixel, en temps réel et pour une résolution de 1024×768. Le rendu est encore être interactif, tant que la visibilité est calculée en utilisant notre nouvelle technique de carte d’ombre (shadow map). Nous proposons également une approche totalement non-biaisée en remplaçant le test de visibilité avec une approche CPU. Parce que l’échantillonnage d’importance à base de lumière n’est pas très efficace lorsque le matériau sous-jacent de la géométrie est spéculaire, nous introduisons une nouvelle technique d’équilibrage pour de l’échantillonnage multiple (Multiple Importance Sampling). Cela nous permet de combiner d’autres techniques d’échantillonnage avec le notre basé sur la lumière. En minimisant la variance selon une approximation de second ordre, nous sommes en mesure de trouver une bonne représentation entre les différentes techniques d’échantillonnage sans aucune connaissance préalable. Notre méthode est pertinence, puisque nous réduisons effectivement en moyenne la variance pour toutes nos scènes de test avec différentes sources de lumière, complexités de visibilité et de matériaux. Notre méthode est aussi efficace par le fait que le surcoût de notre approche «boîte noire» est constant et représente 1% du processus de rendu dans son ensemble. / Realistic images can be rendered by simulating light transport with Monte Carlo techniques. The possibility to use realistic light sources for synthesizing images greatly contributes to their physical realism. Among existing models, the ones based on environment maps and light fields are attractive due to their ability to capture faithfully the far-field and near-field effects as well as their possibility of being acquired directly. Since acquired light sources have arbitrary frequencies and possibly high dimension (4D), using such light sources for realistic rendering leads to performance problems.In this thesis, we focus on how to balance the accuracy of the representation and the efficiency of the simulation. Our work relies on generating high quality samples from the input light sources for unbiased Monte Carlo estimation. In this thesis, we introduce three novel methods.The first one is to generate high quality samples efficiently from dynamic environment maps that are changing over time. We achieve this by introducing a GPU approach that generates light samples according to an approximation of the form factor and combines the samples from BRDF sampling for each pixel of a frame. Our method is accurate and efficient. Indeed, with only 256 samples per pixel, we achieve high quality results in real time at 1024 × 768 resolution. The second one is an adaptive sampling strategy for light field light sources (4D), we generate high quality samples efficiently by restricting conservatively the sampling area without reducing accuracy. With a GPU implementation and without any visibility computations, we achieve high quality results with 200 samples per pixel in real time at 1024 × 768 resolution. The performance is still interactive as long as the visibility is computed using our shadow map technique. We also provide a fully unbiased approach by replacing the visibility test with a offline CPU approach. Since light-based importance sampling is not very effective when the underlying material of the geometry is specular, we introduce a new balancing technique for Multiple Importance Sampling. This allows us to combine other sampling techniques with our light-based importance sampling. By minimizing the variance based on a second-order approximation, we are able to find good balancing between different sampling techniques without any prior knowledge. Our method is effective, since we actually reduce in average the variance for all of our test scenes with different light sources, visibility complexity, and materials. Our method is also efficient, by the fact that the overhead of our "black-box" approach is constant and represents 1% of the whole rendering process.

Syfte: Dagens urbanisering ger behov av förtätning av stadskärnor vilket kan leda till borttagande av parkering, grönområden och solljus. Att bygga och bo i innerstäder är dyrt på grund av höga markpriser, komplicerade projekt och en hög efterfrågan på bostäder. Bostäder idag utformas utefter regelverken SIS och BBR vilket i innerstäder kan få komplikationer. Målet med arbetet är därför att ifrågasätta vissa regler kring tillgänglighet, rumshöjd och ljusförhållanden i syfte att förenkla förtätning och skapa ett nytt förslag av en planerad infill-fastighet där en varierad lägenhetsstruktur uppnåtts tillsammans med en potentiell ekonomisk vinst.   Metod: Arbetets undersökningsmetoder är kvalitativa och består av litteraturundersökningar, dokumentanalyser och intervjuer. Dessa utfördes för att analysera dagens förtätning och resultera i en skissning där byggregler avskaffats för att förenkla viss förtätning.   Resultat: Arbetets skissning visar att en mångfaldig lägenhetsstruktur är uppnåbar via avskaffande av vissa BBR-krav som skapat olika lägenhetstyper, intressanta volymer, tvåvåningslägenheter och yteffektiva planlösningar. Avskaffandet av regler för att förenkla förtätning påverkar inblandade på ett eller annat sätt.   Konsekvenser: Att avskaffa byggkrav i förtätningssammanhang kan ta bort kvalitéer som dagsljus och tillgänglighet i bostäder. Kortsiktiga lösningar på parkeringsbristen finns men förtätning med levande bottenvåningar utförs för att lösa parkeringsbristen långsiktigt genom att skapa tillgångar geografiskt nära människor som minskar behovet av bil. Att avskaffa regler kan leda till enklare projektering och bidra med viss ekonomisk fördel, men dyr nybyggnation tillsammans med hög efterfrågan på centrala bostäder kan försvåra för låga budgetar och prissänkning av bostäder.   Begränsningar: Det generella resultatet av arbetet gällande regelavskaffande fungerar i förtätningssammanhang i andra täta städer men då undersökningen är baserade på Jönköpings innerstad och erfarenheter och åsikter kopplade dit kan generella giltigheten ifrågasättas. Skissningen är baserad på egna åsikter och endast lämplig i detta sammanhang.   Nyckelord: Förtätning, infill, flerbostadshus, urbanisering, byggregler, standard, tillgänglighet, rumshöjd, ljusförhållanden, stadskärna, innerstad. / Purpose: Today's urbanization requires densification of cities, which can lead to removal of parking lots, green areas and sunlight. To build and live in inner cities is expensive because of high land prices, complicated projects and a high demand for housing. Homes today are designed according to the regulations SIS and BBR, which in the inner cities leads to complications, especially regarding accessibility qualities and light conditions. The aim of this work is therefore to abolish certain rules regarding accessibility, room height and lighting conditions in order to simplify densification and create a new proposal of a planned infill property where a varied apartment structure has been achieved together with a potential financial gain.   Method: The research methods of this work are qualitative and consist of literature studies, document analyzes and interviews. These were performed to analyze today's densification and result in a sketch where building rules were abolished to simplify some densification.   Findings: The work outline shows that a multiple apartment structure is achievable via the abolition of certain BBR requirements that have created different types of apartments, interesting volumes, two-storey apartments and surface-efficient floor plans. Abolition of rules to simplify densification affects people in one way or another.   Implications: Abolishing construction requirements in densification contexts can remove qualities such as daylight and accessibility in homes. Short-term solutions to the parking  shortage exist but densification with living ground floors is performed to solve the parking shortage in the long term by creating assets geographically close to people which reduces the need for car. Removing rules can lead to simpler planning and contribute with some economic advantage, but expensive new construction together with a high demand for central housing can make it difficult for low budgets and price reductions in housing.   Limitations: The general result of this work on the elimination of rules works in densification contexts in other dense cities, but since the survey method is based on Jönköping's inner city and experiences and opinions linked to it, the general validity can be questioned. The sketch is based on one's own opinions and only suitable in this context.   Keywords: Densify cities, infill, apartment buildings, urbanization, building rules, standard, accessibility, room height, lighting conditions, city center, inner city.

本研究旨在發展一套互動感知的機制，目的為期望能透過此互動方式，針對長期潛藏著危害健康甚深的「久坐族」，提供一個溫和柔性的「提醒」功能，符合不受「空間的限制」、「設定的限制」、「使用族群的限制」等，亦即凡是因為某些因素導致忽略或是忘記時間而「坐太久」的情形，此類的人便是被提醒的對象。 透過受測者的使用與建議進行分析評估，此互動機制透過分析與歸納，試圖找出區別於坊間常見的提醒模式，如一般人常用的鬧鐘、計時器等硬體，或專為電腦久坐族而設計的電腦健康動畫定時播放軟體等。這類相關的產品不外乎必須受制於人本身要去「記憶」且「手動」去調整、設定、下載、安裝等繁複的過程；另外是提醒的方法和內容瑣碎、不便或是不足，最大的共通限制為「使用時機與空間限制」。因此，本研究中的互動機制預期能提供「久坐族」另一種新鮮的選擇，一種力求「溫馨提醒」、「不受限時空」的互動模式。 為傳達前述的「健康信念」，本研究繼續探討如何將此「互動機制」實際應用於與人類生活當中，透過設計將此互動機制實際應用，結合現代科技與藝術使其更具吸引力與美感。現今已進入以價值為主的高感性經濟時代，體驗經濟能感動人心的關鍵在於將產品與服務提升至碰觸精神心靈的層次。因此運用體驗設計的概念，並嘗試融合與感官直接相關的燈光元素等為創作媒材與靈感來源，進行造型、視覺設計與氛圍的營造，作為接觸人們內心深處的橋樑。 綜合所述，本研究與作品針對「久坐族」預期將達成的五大目標： 1.「健康照護的提醒功能」：設計出感性的互動機制作為基本法則。 2.「獨特的使用者體驗」：將此互動機制結合情感設計增加吸引力。 3.「互動裝置應用（一）」：以結合情境光營造為例。 4.「互動裝置應用（二）」：以結合智慧型手機應用程式為例。 5.「推廣觀念」：藉由以上，推廣久坐族的健康信念。 / This study aimed to develop an interactive sensory mechanism, to hope that through this interaction, for long-term health hazards lurking deep in “sedentary tribe” to provide a soft reminder, without space constraints, setting limits, use of limit etc. All because some of the factors that led to ignore or forget the time “to sit for too long” case, such people is to be reminded. Through the subject's use and recommendations for analysis and evaluation, this interactive mechanism analysis and induction, trying to find a mode which is different from common reminders such as alarm clock, timer or the animation timer player software designed for computer sedentary tribe , and so on. Such related products must be controlled by ourself to remember and set by hands in this complicated process. The method of reminding is trivial、inconvenient, and its greatest limited is "use time and space constraints." Therefore, the interactive mechanism in this study is expected to provide sedentary tribe another new choice, seeking to be the soft and unlimited use of reminder. To convey the aforementioned “health beliefs”, the research continues to explore how this “interaction mechanism” actually applied to human life. The practical application of design, combined with modern technology and art to make it more attractive. Today has entered a value-based、high-touch economic times. Experience economy is the key to raise products and services to touch the spirit of the soul level. Therefore, this study use the concept of experience design, and tries to integrate with the sensory elements as the inspiration for the creative media source for modeling、visual design and creating an atmosphere access to people’s hearts. Above all, the research and work for the “sedentary tribe” is expected to achieve five major objectives：1) “Reminder for health care”：designing sensibility as the basic rules of interaction mechanisms; 2) “Unique user experience”：an interactive mechanism with this design to increase the emotional appeal; 3) “Interactive device applications 1”：an installation with light to create a situation; 4) “Interactive device applications 2”：an combination of smart mobile device applications; 5) ”Promoting the health concept”：by above, promoting the health beliefs.

Their production is small and made by hand in their own workshop in Väskinde with a current collection consisting of 33 lamps. Gotlands Lampfabrik currently does not produce their own lamp fixtures or suspensions but instead buys them from other companies, as a result making the collection seem unclear and incoherent. The current collection also lacks wall lamps and the light sources are outdated light-bulbs that are slowly being taken off the market after a decision from the EU. The possibility to select well designed lamps from a series for your home are both in high-demand and can provide a sense of coherency and well though-out interior design for the consumer. By making a new, carefully put together product series and lamp-foot, branding for Gotlands Lampfabrik would be easier and help their lamps have a more clear product identity. In a close collaboration with Jonas we both agreed that I would create a new product series for Gotlands Lampfabrik with a distinct design relationship within the new series. The product series would include a hanging lamp, a floor lamp and a table lamp but after some discussion and studies we took the decision to replace the table lamp with a wall lamp since Gotlands Lampfabrik lacked this fixture in their collection. The project started with a pilot study where I did market research, a survey and investigated trends within lighting and lamps. After I compiled these facts I made sketches and models and presented them for Gotlands Lampfabrik. Together with Jonas we discussed and picked our favourite concepts which was developed further. The final concept we both agreed on was produced by me in their workshop. The project resulted in three lamps and a modular system for the floor lamp fixture where consumers can select the shape and materials by themselves. All lamps are equipped with a textile cord for a more exclusive feel and are designed in the white plastic laminate that Gotlands Lampfabrik already use in production. The lamps also have a small label on the cord which shows that it comes from Gotlands Lampfabrik. The light source that had most benefits, and was well suited for this project was Philips MasterLED 7W.

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. The test subjects did perform a test where they estimated their individual need for lighting in office environments regarding lighting for workplace and its surroundings. Every test subject carried out the test where they repeated the same attempt three times, to establish if the individual lighting need oscillated or if it was constant, whereupon the results were analyzed, compiled and compared to standard SS-EN 12464-1. The results show that the minim- and maxim value for the test subjects is between 70 – 4300 lux. The result varies with different parameters such as sex, age and glasses/lenses. We could also state that the relationship between workplace- and surrounding light levels is slightly higher than what standard SS-EN 12464-1 recommends, which should be taken into consideration when planning future lighting constructions. Based on the results in this study, our conclusion is that standard SS-EN 12464-1 does not cover the needs on the comfort levels that the test subjects indicated. The values that the test subjects indicated differ from the values that standard SS-EN 12464-1 recommends. Since there is a huge spread of the experienced need for lighting between individuals and age groups, we draw the conclusion that general values of measure can’t be applied as a standard on neither workplace- nor surrounding light levels. To fulfill the needs that users have, the lighting construction should be adapted for the individual and give a lighting flood that will fill the individual needs for workplace lighting.
