Title (EN) SYSTEMS FOR PROVIDING TUNABLE WHITE LIGHT WITH HIGH COLOR RENDERING
(FR) SYSTÈMES DE PRODUCTION DE LUMIÈRE BLANCHE ACCORDABLE À RENDU DE COULEUR ÉLEVÉ
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 destinés à produire de la lumière blanche accordable. Les systèmes comprennent une pluralité de chaînes de DEL qui produisent de la lumière ayant des points de couleur qui se situent dans les gammes de couleurs bleu, jaune/vert, rouge et cyan, chaque chaîne de DEL étant entraînée à l'aide d'un courant d'entraînement à commande séparée afin d'accorder le flux lumineux produit.
