LED LIGHT FOR EXAMINATIONS AND PROCEDURES

A light (20) is provided having a base unit (22), an arm (24) extending from the base unit (22), and a lamp head (26) coupled to the arm (24). The lamp head (26) includes an LED (70) configured to provide light based on an input drive current (I), an optical mixing element (72) configured to collect...

Zusammenfassung:	A light (20) is provided having a base unit (22), an arm (24) extending from the base unit (22), and a lamp head (26) coupled to the arm (24). The lamp head (26) includes an LED (70) configured to provide light based on an input drive current (I), an optical mixing element (72) configured to collect the light produced by the LED (70) and a zoom lens (48, 52) configured to adjust an output size of a spot (78) generated by the light collected in the mixing element (72). A controller (84) receives DC power from the base unit (22) through the arm (24). The controller (84) (is configured to set the input drive current (I) for the LED (70) to control an output light density of the spot (78) in response to an operator selected input and configured to adjust the output light density of the spot (78) in response to a change in the size of the spot (78). L'invention concerne une lumière (20) comportant une unité de base (22), un bras (24) partant de l'unité de base (22) et une tête de lampe (26) couplée au bras (24). La tête de lampe (26) comprend une DEL (70) conçue pour fournir de la lumière en fonction d'un courant d'actionnement d'entrée (I), un élément de mélange optique (72) conçu pour recueillir la lumière produite par la DEL (70), et une lentille de zoom (48, 52) conçue pour ajuster la taille de sortie d'un point lumineux (78) généré par la lumière recueillie dans l'élément de mélange (72). Un contrôleur (84) reçoit une alimentation CC de l'unité de base (22) via le bras (24). Le contrôleur (84) est conçu pour ajuster le courant d'actionnement d'entrée (I) de la DEL (70) afin de commander la densité de lumière de sortie du point lumineux (78) en réponse à un changement de la taille du point lumineux (78).
