Development of a door accessory to transport daylight into the hallway (English)
Abstract [sv]

Designingenjörerna Ida Evervall och Toni Maric från Högskolan i Skövde har under våren 2014 arbetat med ett produktutvecklingsprojekt tillsammans med en dörrtillverkande uppdragsgivare. Dagsljusinsläppet till hallar i lägenheter är i princip obefintligt och lampor används för att tillgodose behovet av ljus. Ett dörrtillbehör har utvecklats i syfte att samla in ljus från utsidan av lägenheten och transportera detta genom dörren till insidan, helt insynsskyddat. Uppdragsgivaren ville att transporten av ljuset främst skulle ske med hjälp av fiberoptik. Efter experiment framkom att fiberoptiken var tillräcklig för att transportera ljuset, en insamlande lins framför gav betydligt bättre resultat soliga dagar. Molniga dagar ansågs det vara tillräckligt att markera dörrens position. Utifrån marknadsundersökningen bekräftades att mörker i hallen var ett faktum och kravet om ett insynsskyddat dörrtillbehör lyftes fram tillsammans med krav på pris och övriga säkerhetskrav som brand, ljud, inbrott etc.

Flera lösningar till delfunktionerna för dörrtillbehöret genererades, kombinerades och utvecklades. Utvärderingar utfördes i form av tester och diskussion med uppdragsgivare. Därefter valdes ett koncept som namngavs till BeeLight. BeeLight består av en pentagonformad lins omringad av fem vinklade hexagona linser som koncentrerar ljuset in i det fiberoptiska knippet. Den insamlande linsen är en lösning som samlar in ljus från olika riktningar då solen förflyttar sig under dagen. Ett enkelt test visade att BeeLight ger ungefär 10 lumen ljus en solig dag. Fler tester bör genomföras i syfte att få fram exakta siffror på hur mycket ljus BeeLight kan tillgodose hallen med.

Abstract [en]

During spring 2014, Ida Evervall and Toni Maric from the University of Skövde have carried out a project with a door making company. Daylight admission into to hallways in apartments is basically non-existent today and lamps are used to satisfy the need of light. A door accessory has been developed in order to collect light from the outside of the apartment and transport it through the door to the inside, with no transparency. The client wanted that the transport of light would mainly be done with fiber optics. Experiments showed that fiber optics were sufficient to transport the light, a collecting lens in front gave significantly better result in sunny days. Cloudy days, it was considered enough to mark the position of the door. A market research confirmed that dark hallways was a fact and that transparency-protected door accessories was highlighted together with requirements for price and other safety requirements such as fire, sound, burglary etc.

Several solutions to the sub-functions of the door accessory were generated, combined and developed. Evaluations were carried out in the form of tests and in discussion with the client. Then one concept was elected and named BeeLight. BeeLight consists of a pentagon-shaped lens surrounded by five hexagonal lenses that focus the light into the fiber optic bundle. The collecting lens is a solution that collects light from different directions as the sun moves throughout the day. A simple test showed that BeeLight provides about 10 lumen on a sunny day. More tests should be conducted in order to obtain exact numbers on how much light BeeLight can transport into the hallway.
