Framtagning och miljömärkning av kvicksilverfri xenonstrålkastare
The project this report is handling has been implemented on NBB, Nordisk Bilbelysning AB in Linköping. The company produces and develops lightning and searchlights for all types of vehicles. Lately NBB´s supplier of electronics, OSRAM, has developed a mercuryfree xenon lightsource. Mercury is one of the most hazardous environmental waste and to get rid of the mercury entirely in the lightsource is a big step that means alot for the environment.This lightsource will be placed in one of NBB´s worksearchlights called My, and will be sold as an alternative to mercurycontaining searchlights. NBB wants to put an environmental label on this product and they want to have essential information about the product that is needed for the production. That is what the project has handled. A study of environmental labeling has been made witch has led to that an environmental declaration type II will be used as labeling and marketing for the environmental properties the serachlight has.The purpose of this master's thesis is to help and support NBB in environmental labeling and developing of a My searchlight with mercuryfree lightsource. A environmental labeled searchlight would mean a bigger place on the market and consequently lowered environmental affect.Lifecycleanalysis with the program ECO-it shows that a mercuryfree lightsource in the searchlight would not involve a environmental profit compared to a mercurycontaining lightsource because the lifelenght of a mercuryfree lightsource is 500 hours shorter. This means that the lightsource has to be changed more frequently if you choose the mercury free alternative and that affects the environment.The lifecycleanalysis also shows that the transports of components affects the environment little in compare to the production of the product and therefore a change to Swedish suppliers has not been implemented.Temperatur and lightmeasures has been made and compared between the searchlight containing mercury with the searchlight not containing mercury. The results of the measurements shows that the flow of light from a mercury free searchlight is about 15% lower and the temperature inside 5°C higher. This means that the construction not has to be changed as the temperature is on a acceptable level.The use of mercury in lightsources will likely not be used forever as new law demands becomes stricter and stricter by time. The environmental declaration that was made contains among other things a list of materials of the product and information about the products lifecycle. A logotype has also been suggested as a environmental label logotype for the company to use. The environmental declaration will be used as marketing of the product on the company website for exemple.
