Star-shaped heatsinks for LEDs

19 August 2009 Passive Components

Fischer Elektronik has developed a range of aluminium heatsinks, the dimensions of which match the majority of current round housing designs.

High power (HP) LEDs and high brightness (HB) LEDs for lighting purposes offer great opportunities for the lighting industry, as LEDs are energy efficient and potentially highly reliable. In view of the high power density of these LEDs, a major challenge is safe and effective heat dissipation, in order to ensure trouble free operation, good light yield and a long service life.

The shape of lamp housings or the positions in which they are situated is often rotationally asymmetric, so that round bodies are required for heat dissipation. Fischer’s heatsinks, which are offered with different diameters and contours, are available in different sections of different lengths to suit specific heat dissipation applications. The LEDs are fastened onto the heatsink using thermally conductive, double-sided adhesive tape, 2-component thermally conductive adhesive or screws. In the standard version, the surface is black anodised or of natural colour. In addition to standard heatsinks, specially modified and customised versions are available.
