INFÄSTNING AV LED-ARMATUR
The thesis was performed at the lighting company Zpecta AB. Zpecta needed to develop alternative attachment of their LED-luminaire Capella. Today Capella attaches in metal ceilings with four magnets. Zpecta got indications from their customers that there was a need for other attachments. The purpose is to determine the customer?s requirements and the interfaces that are considered for Capella.During the thesis, Capella was only on the market for testing and evaluation.The thesis was initiated to create a specification. The specification would cover all the demands and wishes Zpecta and their customers have. The specification should also contain the regulatory requirements. To find out the requirements for a luminaire, an information research was conducted by visiting customers, researching the Internet, verbal information and by studying literature.Design concepts were developed to attach the Capella to ceilings made of wood, concrete and plaster, with wire suspension, at system ceiling, acoustic ceiling and at 3-circuit track.Capella?s magnetic attachment was tested in order to the specification. The result showed that the magnetic attachment did not meet the requirements. Therefore a solution, that meet the requirements for the magnetic attachment, would be developed and also an alternative design solution for mounting at 3-circuit track.The design concepts were evaluated by using the Pugh selection matrix and a questionnaire. Three design solutions were developed for mounting at 3-circuit track and wire suspension. The design solutions were presented as an assembly in SolidWorks, with a manufacturing method, a FMEA and a cost estimate.For the three design solutions that were developed, there have to be prototypes for testing to get knowledge about how well the design solutions meet the specification.
