Title
(EN) LIGHT EMITTING DIODE LIGHT ENGINE
(FR) MOTEUR À LUMIÈRE À DIODE ÉLECTROLUMINESCENTE
Abstract
(EN)
An LED light engine system that incorporates light emitting diodes (LEDs) with one or more distinct colors, including broad band white light obtained from phosphors or a combination of LED die colors and LED die coated phosphors. The LED die or die arrays are mounted to a high thermal conductivity circuit board comprising COB technology which can include both the LED die and electronic drive components resulting in a compact and reliable design with improved thermal and optical performance. High efficiency non-imaging collection optics are coupled to the LEDs to efficiently capture substantially all of the light which they emit and reformat it as an output with substantially the same ntendue as that of the LED to provide high brightness sources. Feedback from the output back to a photosensor on the circuit board is provided to assure that the output of the collection optic remains constant.

La présente invention concerne un système moteur à lumière LED qui incorpore des diodes électroluminescentes (LED) avec une ou plusieurs couleurs distinctes, qui comprennent une lumière blanche de large bande obtenue à partir de substances luminescentes ou d'une association de couleurs de dé LED et de substances luminescentes de dé LED. Le dé LED ou la série de dés LED sont montés sur une carte de circuit imprimé à haute conductivité thermique qui comprend une technologie COB qui peut comprendre le dé LED et les composants pilotes électroniques, ce qui entraîne une conception compacte et fiable avec des performances thermiques et optiques perfectionnées. Des éléments optiques de collecte de non-imagerie à haut rendement sont couplés aux LED pour capturer de façon efficace sensiblement toute la lumière qu'elles émettent et la reformater sous forme de sortie avec sensiblement la même étendue optique que celle de la LED pour fournir des sources de luminosité élevée. La rétroaction à partir de la sortie vers un photocapteur sur la carte de circuit imprimé est fournie pour garantir que la sortie de l'élément optique de collecte reste constante.
