The aim of my master’s thesis is the design of the LED lighting system for breeding and growing purposes as replacement for the classical high-pressure sodium lamps and other sources of light used today. The whole system can be controlled locally by buttons or remotely by web server using Ethernet interface. LEDs are powered by five-channel step-down converter with current feedback. Converters are controlled by pulse width modulation generated by microcontroller.

Grüne Werbebotschaften gibt es bereits zu Hauf – auch in der Beleuchtungsbranche. Nach aktiver Beteiligung an Forschungsprojekten zur Nachhaltigkeit von LED-Beleuchtung ist uns eines klargeworden: Wir brauchen immer noch mehr Leute, die die richtigen Fragen stellen, und weniger solche, die ihre Meinungen als die ultimativen Lösungen verkaufen.

過去台灣LED產業伴隨著面板業的發展而崛起，但目前正是投入LED照明，放眼進千億美元市場的機會，本研究針對傳統照明大廠OSRAM於技術、專利、與商業策略等角度分析，探討LED照明的佈局策略，期望能給台灣LED廠商一些啟發。整體而言，LED照明取代傳統照明的趨勢是肯定的，關鍵在於LED照明的價格走勢以及政府政策的支持。目前雖然LED照明市場仍然以美國為主，但以整體亞洲市場而言，市佔率已經越來越高。而亞洲區域市場最重要的國家－中國，目前在LED照明應用市場僅次美國，差距已經越來越小，未來極可能成為最主要的市場。 在一開始進入半導體照明時，OSRAM受惠於母公司Siemens，在專利、技術上就已取得領先，OSRAM並採取垂直整合的策略，從磊晶、晶粒、封裝、模組都有佈局，使LED的生產更有效率。除此之外，由於未來LED照明產業的趨勢是照明整合服務，OSRAM也透過併購的方式，補強照明設備、照明系統的能力。未來OSRAM不僅供應LED元件，也提供照明解決方案，觸手一路延伸至終端應用。OSRAM初期都是以合資為主以分散風險，若合資公司經營順利，OSRAM便以併購的方式，強化OSRAM的全球佈局。此外，OSRAM 建立了一個平台，聚集了熱管理、光學、電子相關的專業廠商，以及照明整合的系統廠商，形成產業群聚，一方面可以鞏固供應商、被供應商關係，一方面透過產業群聚的效果，建立緊密的合作網路。此外，於經營策略方面，不僅提供整合型產品，開拓銷售管道，且透過生產基地的轉移，降低生產成本，並隨著市場導向，轉換銷售區域，加強於亞太地區的在地化發展。最後，OSRAM之專利申請策略配合市場需求，且除了LED以外，也鞏固OSRAM於省電燈的領先地位；在專利授權部份，OSRAM採取開放式專利授權策略，為Nichia增加競爭者，也為自身帶來大量的授權金以及代工廠商。 研究結論顯示，OSRAM成功的因素在於掌握專利、品牌以及通路，以及LED元件垂直整合的供應鏈，並積極的貼近市場，瞭解市場趨勢，將LED光源技術的挑戰成功的轉化成OSRAM新的產品線。因此本研究建議台灣廠商應與中國之照明廠商合作，台灣廠商於LED技術以及製造仍具優勢，但缺乏品牌以及通路的佈局，台灣LED廠商與其自己發展品牌，不如以代工的方式與既有的傳統照明品牌廠商合作，與中國照明廠商合力抵抗來自國際照明廠的威脅。此外，台灣廠商應認清產業定位，台灣於半導體、電子領域擁有領先技術，可以從LED照明產業鏈的中游模組切入，像是熱處理或是驅動IC等，會是台灣廠商切入照明產業的利基。 / The LED manufactures in Taiwan now actively involved in the general lighting application of LED. In order to provide the manufacturers with some suggestions, the main goal of this thesis is to study OSRAM’s LED lighting layout and strategy, including patent, technology and business strategy. In the long run, LED lighting replacing traditional lighting is in a positive direction. Key factors are the price of LED lamps and the support of government policies. At the present time, the US market is still the main market. However, the market share in Asia-Pacific is steadily increasing. The most important country in the Asia-Pacific region, China, is getting closer and very likely to become the most important market in the near future. Benefited from parent company, Siemens, OSRAM took the leading position at the beginning of semiconductor lighting. OSRAM then adopted the strategy of vertical integration of epitaxy, chip process, packaging and end applications. Therefore, OSRAM can manufacture LED products in a more efficient way. Furthermore, OSRAM also reinforces the capability of the lighting fixtures and lighting systems via mergers, acquisitions, and joint ventures. OSRAM not only provides LED components but also lighting systems and solutions. To spread risks, OSRAM use joint ventures instead of mergers and acquisitions in the beginning. Once the company has operated smoothly, OSRAM will then merge the company. In addition, OSRAM has established a platform to gather companies that provide electronic, optical, or thermal solutions. Industry cluster is formed. With the effect of cluster, the relationship between buyers and suppliers is enhanced. About business strategies, OSRAM developed integrated products to extend channels and moved manufacturing overseas. Referring to patent application strategy, OSRAM meet the demand of market. In addition to LED-related patents, OSRAM also filed many efficient lamp patents these years. And OSRAM actively licensed patents to other companies, not only created competitors against Nichia but also received licensing fee. In conclusion, the main reasons why OSRAM succeed are the strategies of brand, channel and patent. As the lack of branding and channel, this study suggests that Taiwan manufacturers could cooperate with traditional lighting companies in China. With the OEM service of Taiwan manufacturers, supplying LED components, and the channels and brand of China lamp manufacturers, Taiwan and China may have a chance to compete with other international companies. In addition, Taiwanese firms should recognize their positions in the industry value chain. In addition to building a brand, investing in LED lamp, there’ll be a better choice to develop midstream light engines like thermal management or driver IC.

The aim of the thesis is to design a system based on wirelessly comunicating devices that will be able to record an information about persons presesce in certain area. Aquired data will served for evaluation of the area lighting system efficiency. Partial goals related to this work are: to analyze electricity consumption mesaurement methods, to analyze presence and movement detection methods, to analzye wireless communication methods, to desin system's HW and SW including realization, to put system into a real operation and finally, to evaluate measured data.

The aim of this thesis is the development of electronic circuitry for remote controlled bathyscaphe and allow it to move, measure the working values and transmit the video stream from IP camera to the computer. Camera itself can be also remotely tilted by a small servo motor. The bathyscaphe is controlled through a simple computer program.
