LedHeatSink.it is a website of F.lli Poli, a company established in 1968 which stands out for its technical expertise in design, mechanical processing technologies on metals (drawing and warping dies, machining on metal, forming, 3D laser cut, assembly) and for the ability to provide its customers with comprehensive solutions.
An extensive experience in many sectors, know-how and fondness lead us to start a project with the University of Padua concerning materials and heat dissipation. In the lastyears, we developed innovative cooling solutionsand systems especially focused on power LEDs. Such new heat sinks are built out of aluminum fins, an aluminum base and “heat pipes” which optimise the LEDs performance.
The refined and extraordinary captivating shape allows this innovation to be installed on downlights as well as on decorative lamps. Dissipation takes place in a passive way without any operating devices that would just increase costs, consumptions, noise and be a source of possible breakages. In addition to heat sinks F.lli Poli offers metal accessories for lighting technique such as front frames and,baskets for downlight applications.
Due to its modularity, the heat sink can be easily customised according to client’s requirements. In particular, the dissipation rate can be increased just by lengthening the heat sink while keeping the same diameter.
This feature goes beyond the limit of traditional heat sinks whose length shall be proportional to the diameter. On demand, our heat sinks are available in various colors, shapes and powers.
LED “Light-emitting Diode” is a new way to perceive the light with some advantages in terms of energy saving, low maintenance costs and respect of the environment (less CO2 emissions and absence of UV-radiation). In order to increase its efficiency and avoid an early wearing of the optical-electronic properties, the LED device requires an appropriate control of the input current and has to operate with Tc (T case) temperatures not exceeding 85 °C. For this reason, a cooling system able to keep the right temperature of the junction shall be coupled to the LED device. In collaboration with the University of Padua, F.lli Poli snc has conceived and developed a dissipating system whose technology integrates with a refined design, where the selection of materials and new technologies guarantee an excellent solution for a better efficiency of the LED.
• They have a refined, harmonious and attractive design of considerable aesthetic value. • The temperature is distributed more uniformly compared to traditional heat sinks by reducing the temperature around the LED and rendering the device more efficient. • A thorough study carried out as to shape, size and number of fins guarantees excellent performances, irrespective of the inclination of the heat sink. • The shape of the fins can be easily customised. • The dissipation takes place in a passive way without operative devices which would just increase costs, consumptions, noise annoyance and generate possible wearing and failure. • Under the same dissipation rate, the weight of the new heat sinks are halved compared with that of traditional devices.
