Light emitting diodes are prepared with specialized packages which provide a dosing feature with respect to a phosphor wavelength converting medium. Elements of the device package form a specially shaped cavity when coupled together. The shape and size of the cavity operates to control the dosing of phosphor spiked medium of soft gel. The gel fills the cavity such that light emitted from a semiconductor die is exposed to a similar cross section independent of the exact direction of light propagation. In this way, 'white' LED systems are formed from blue emitting diodes as highly controlled phosphor dosing permits precise amounts of blue light to be converted to yellow light without problems with angular uniformity observed in competing technologies.

Des diodes électroluminescentes sont assemblées sous forme d'ensembles de support spécialisés dotés d'une fonction de dosage par rapport à un milieu de conversion de longueur d'onde de phosphore. Des éléments dudit ensemble ménagent une cavité d'une forme particulière lorsqu'ils sont accouplés. La forme et les dimensions de ladite cavité servent à réguler le dosage du milieu additionné de phosphore et se présentant sous la forme d'un gel mou. Ce gel remplit la cavité de telle sorte que la lumière émise par une puce à semi-conducteurs est exposée sur une section transversale similaire, indépendamment du sens de propagation précis de la lumière. On obtient ainsi des systèmes de DEL "blanches" à partir de diodes émettant de la lumière bleue, puisque le dosage hautement régulé du phosphore permet de convertir des quantités précises de lumière bleue en lumière jaune sans les problèmes d'uniformité angulaire rencontrés dans les technologies concurrentes.
