The Little Star package is designed for high current application up to 400mA, with a super high flux output and presented in a compact package outline. With its low package height of 1.5mm it presents the best combination of compactness and highest brightness. The following application note details product specification in corresponding data sheets for the different series of the product.

Besides the handling recommendation, a proper thermal management is the most important part for the design in of high power LED. Driving the LED a high portion of the electrical energy will be converted to heat. This heat conducts from the junction area through the LED die, then trough the package and finally to the ambient via the heat sink. The following application note describes all this phenomena in detail and gives the necessary instructions for an efficient application and a long LED life time.
