CA 2464141

Broad spectrum light emitting devices and methods and systems for fabricating such devices are provide. Such devices may include a light emitting element, such as a diode or laser, which emits light in a predefined range of frequencies, and luminous material on the light emitting diode. The characteristics of the luminous material, such as the amount, composition and/or doping of the luminous material or materials may be based on measured light output of the light emitting device, such as the measured output frequency and/or power of the light emitting device.

L'invention concerne des dispositifs électroluminescents à large spectre ainsi que leurs procédés et systèmes de fabrication. Ces dispositifs peuvent comprendre un élément électroluminescent, tel qu'une diode ou un laser, qui émet une lumière dans une gamme de fréquences prédéfinie, ainsi qu'une matière luminescente disposée sur cette diode électroluminescente. Les caractéristiques de la matière luminescente, telles que la quantité, la composition et/ou le dopage de la ou des matières luminescentes, peuvent être fondées sur les valeurs de sortie de lumière mesurées du dispositif électroluminescent, et notamment sur la fréquence et/ou la puissance de sortie mesurée du dispositif électroluminescent.
