This year, the Red Dot Award for product design in the category "light and luminaires" goes to Oktalite for the QUAD spotlight / Innovative material enables innovative design and improved CO2 balance.
Innovativeness, functionality, environmental compatibility - these are just three of the criteria that the international jury of this prestigious design prize uses to select the winners. The QUAD LED spotlight from Oktalite meets these criteria in part thanks to its ceramic heat sink. This material achieves a CO2 balance up to fifty percent better than aluminium. At the same time, the ceramic conducts heat much more effectively than aluminium so that the heat generated by the LED can dissipate directly into the material, with no active cooling necessary. The ceramic material used is also slightly transparent, so that the heat sink itself becomes a design element. As the material has a low electrical conductivity, individual LED packages can be mounted directly on the heat sink. This enables an extremely flat format of just four centimeters. In all, the 15 LED packages as individual light points output a luminous flux of 3,600 lumens. Every light point feeds a collimator, which bundles the light to create a tight spot with no light scattering. Using lens disks that can be swapped out without the need for tools, beam angles such as spot or medium flood can be produced as needed.
The family-owned shoe retailer Schuhhaus am Bieltor in Solothurn, Switzerland, chose LED technology for its reopening in August 2013.
The Swiss family enterprise Schuhhaus am Bieltor offers fine Italian and Spanish leather shoes in a store one hundred square meters in size housed in a landmark structure. Following renovations by the firm Architektur-Büro Unzen, the light planning in particular was confronted with special challenges. On account of the exceptionally low ceilings, luminaires were needed that radiate virtually no heat. The valuable leather shoes also had to be protected from UV and infrared radiation. Consequently, LED technology was chosen, which is considered particularly gentle on merchandise as it emits virtually no UV or IR radiation. With the Cardan Vario Compact recessed directional spot for the sales area and the Fano surface-mounting directional spot for the display window and POS area, Oktalite supplied two products that, at 3500 kelvins and 4000 lumens provide sufficient light while at the same time creating a pleasant shopping atmosphere. With a service life of 50,000 hours, these luminaires demonstrate exceptional sustainability.
Store opens in London with new lighting concept / excellent results with LED illumination convinces sporting-goods manufacturer
Energy efficiency, rapid implementation and accurate realisation of market identity – these were the key objectives for the lighting concept of the new Reebok store in London's Covent Garden shopping district. Original plans called for the deployment of 70W halogen halide lamps. After consulting light specialist Oktalite, however, brand manufacturer Adidas, to which Reebok belongs, decided to go with a more efficient technology. Thus, the Cologne-based enterprise executed the project of illuminating 200 square meters of store space using LED luminaires. The Taro surface-mounting spotlight was ultimately selected, equipped with 3000 and 4000 lumen elements and a light colour of 3000 kelvin. Oktalite additionally met the customer's desire for specially adapted suspended luminaires: suspended closely together, they provide the new Reebok store with a very special eye-catcher.
The use of LED technology reduced energy consumption by 25 percent. In addition to the positive energy balance and the accentuated, atmospherically dense properties of the light, the sporting-goods manufacturer was also impressed by the short delivery time. Oktalite had only a very narrow time window from placement of the order to the store opening. Complete customer satisfaction was achieved through attainment of the third target: the Cologne-based experts implemented the 3D visualisation of the store that reflects Reebok's corporate identity virtually flawlessly.
Oktalite's LED reflectors are made from the highly reflective material Miro-Silver®. Miro-Silver has an exceptional 98% reflectivity and is ranked in efficiency class A+. In designing the reflectors, Oktalite's developers opted to construct them out of segments of pre-anodized strip material. Advantages of this approach: It enables a precise calculation of the reflector geometry, enabling the reflector material to achieve maximum effectiveness – a large portion of directed reflection with a low diffusion portion and greatly reduced dazzling. Additionally, the reflective property of the material remains the same over the entire reflector surface. Thus, every point on the reflector can direct the light precisely where it's needed. The resulting defined light cone utilises the luminous flux of the LED effectively, generating high illuminances. As this design enables reflectors to be fabricated both rapidly and precisely, individual, ad-hoc customer requests can be fulfilled quickly and exactly. To enhance luminaire efficiency even further, Oktalite integrates these reflectors perfectly in your luminaires.
