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).
