Abstract:Introduction The sun is the best-known light source. Sunlight influences health both physically and mentally. There are also artificial sources of light that imitate sunlight. A wellknown example is the solarium. In the past years the Dutch firm Sunshower B.V. developed several products for showering with high frequent (ultraviolet) and low frequent (infrared) artificial light. A major disadvantage of one of their built-in products (the Sunshower Deluxe Health) is the decoration strip catches the eye too much. Therefore the purpose of this research was to develop this builtin product in such way that the decoration strip could be left out. Another goal was then to attach the glass plate in a different way and to design a new wall frame. The slogan was ‘’Less is more’’. Method First of all a range of demands was drafted for the new built-in model. Secondly the type and number of magnets were assessed that had to be attached to the frame to fix the glass plate on the wall frame. Subsequently a fitting glass plate was searched for with sufficient force to be secured by the magnets. Also a suitable plate stand was tested. Obviously the barrier between glass plate and wall frame with lamps had to be waterproof. For this objective numerous design drafts, calculations and tests were made. Also it was tested how many power was necessary to pull the glass plate from the wall frame (for recovery of replacement). Finally the wall frame of the new built-in model was reconstructed on basis of the specifications of the separate parts. Results Eight magnets with a fixing power of 11 kg each were necessary to secure the glass plate (length 1878mm, width 316mm and depth 4mm) with not equilateral L-profiles of steel on the wall frame. A plate stand with a triangle fit was developed to achieve a central position of the glass plate on the wall frame. A crushable, self adhesive rubber strip (15x15mm) was chosen to guarantee water resistance with a compression of 6mm. Unfortunately this test failed because the rubber seemed to exist of semi-closed cells. The power to pull the glass plate from the wall frame was both tested and assessed. In reality the power was 98N, after calculation the power was 170N. This difference was explained partially by the fact that the securing force of a magnet is dependent from the material of the fixing object (glass plate with L-profiles of steel). On the basis of previous specifications the extrusion profile of the wall frame was adapted. For example the profile was lengthened on the location where the rubber strip would be attached. Also a protrusion was made in the profile to withdraw the rubber strip from the sight. The new built-in model was complying to the range of demands fully, with exception of being waterproof. Conclusion In conclusion the development of a new built-in model of the Sunshower Deluxe Health was successful. The decoration strip has been left out. The glass plate has been attached smartly on magnets in a wall frame that has been changed partially. Unfortunately the barrier was not yet waterproof. One of the advices to Sunshower B.V. is to use a closed-cells rubber strip when attaching the glass plate to the wall frame, so the rubber will be waterproof.
