The luminaire Minimum utilizes an open-pore aluminum foam for cooling the high-power LED lamp. This versatile engineered material is used in various special applications. Both thermal and mechanical properties are used to enable technically demanding processes. Various parameters, e.g. Poresize and cross-section, can be varied to achieve the desired material properties. Compared to solid heat sinks the advantages are direction-independent convection, low density and aesthetic ease.
By fine-tuned material proportions it is possible to use a chimney effect as cooling. The smoke-test is clearly demonstrating the flow suction that uses the acceleration of the rising heat to draw cool air through the aluminum foam. Through the infrared camera it becomes clear how the various areas of the material react during the heating and cooling phases.
Only with a well-designed cooling system LED´s can fully play out their advantages. Through this design longevity and efficiency are also ensured in the high amperage range.
The reflectors we have developed are optimized by using a specific software. Precise statements in the simulation guide to our concrete reflector geometries. Depending on the lighting requirement, these can be replaced without the use of any tools. The indirect light content for the wall and ceiling can be adjusted precisely in this way.
