Title (EN) SYSTEMS FOR PROVIDING TUNABLE WHITE LIGHT WITH HIGH COLOR RENDERING
(FR) SYSTÈMES FOURNISSANT DE LA LUMIÈRE BLANCHE ACCORDABLE À FORT RENDU DE COULEUR
Abstract:
(EN) The present disclosure provides systems for generating tunable white light. The systems include a plurality of LED strings that generate light with color points that fall within blue, yellow/green, red, and cyan color ranges, with each LED string being driven with a separately controllable drive current in order to tune the generated light output.
(FR) La présente invention concerne des systèmes de génération de lumière blanche accordable. Les systèmes comprennent une pluralité de séries de diodes électroluminescentes qui génèrent de la lumière grâce à des points de couleur qui se situent dans les plages de couleur du bleu, du jaune/vert, du rouge et du cyan, chaque série de diodes électroluminescentes étant commandée par un courant d'entraînement à commande séparée afin d'accorder la lumière ainsi générée en sortie.
