Abstract:This bachelor thesis aims at acquiring specific knowledge about the current Organic Light Emitting Diodes (OLEDs) so as to find a suitable application for an OLED lamp and create a design guide for lamps with OLED panels. In addition a lamp with at least one OLED panel has been designed within this bachelor project A thorough analysis is one of the essential requirements for this bachelor project. Light, the usage of light and its effects on the humans have been first studied. Then the OLED technology is examined to understand the characteristics of OLEDs for being able to use them in lamp designs. The results from both studies are essential for being aware of which purpose OLED lamps can be used for. Moreover the current market has been analysed via internet, magazines and fair trades. The visit of two fair trades in Cologne and Bad Salzuflen was used for getting knowledge on the usage of light in furniture designs and for talking with members of lighting companies. This is essential for getting to know the currently available OLED panels, their characteristics and their place on the market. The design office OTT-DESIGN is also studied shortly within the analysis section. Finally all achieved knowledge is summed up in a list of requirements. Then as many ideas as possible have been generated leading to nine different concepts. For each application (kitchen, office and bathroom), three concepts have been designed. These three rooms are relevant for the design office OTTDESIGN and the use of OLED panels is possible in these areas. Moreover all lamps have individual characteristics and extra functions resulting in nine different concepts. Finally the first kitchen concept is chosen at the end of a discussion with the owner of the design office Niko Ott. This concept has the highest potential for the design office. Indeed OTTDESIGN is often working together with kitchen companies and of course lighting companies. The final lamp consists of three parts: an Upper Lamp, a Side Lamp and two possible add-ons. A flexible OLED panel is integrated in both lampparts. The three parts are fixed in the corner between the underside of the wall cupboard and the wall itself. The aim of the lamp is to illuminate the work top from above and the side to minimize the appearing shadows on the work top. Moreover the homogenous and glare free light present the food in its original colour due to the high Colour Rendering Index of OLEDs. The required illuminance of 500lx can be achieved by mounting more OLED lamps next to each other. In this good light condition the user can prepare meals in a suitable environment. All lamps can be easily controlled with a touch sensor or an app. The two add-ons are either a loudspeaker with an USB - and Bluetooth connection or a plug socket with an USB port for charging electrical devices. Furthermore all three parts can be combined in every possible way. The lamp can then get a personal characteristic and kitchen designers and users can choose their own lamp combination. In the end of the thesis the project and the resulting design have been evaluated. Of course no product is perfect and there are always some achievable improvements. In this case the lamp needs some further developments regarding the add-ons before the final production. Moreover the cost calculation has to be improved. The current price of OLED is used for the calculation but a mass production is soon possible which will decrease the price of the panels. A functional prototype should also be made before the production to see if everything is fitting and working fine. Unfortunately it was not possible to build a prototype within this project due to the high prices of a 3D print and the OLED panels. However, the OLED-Technology will improve within the next years and the OLED panels will get an efficient light source. Thus having knowledge about OLED panels and having OLED lamp designs is a good preparation for the future lighting market.
