Surgical light with beam redirecting optics

摘要

A surgical light including a substrate having a substantially planar top surface with a plurality of light sources on the substantially planar top surface, with each of the light sources emitting light in a cone when activated. The cone has a first spread angle. An optical system having a first area such that the light emitted from the light sources has a second spread angle after passing through the first area and a second area focusing or redirecting the light passing through the first area at a location a desired distance from the optical system. The second spread angle is less than the first spread angle.

主权项

1. A surgical light comprising:
an arm; and a light assembly connected to the arm; the light assembly comprising:
a housing;a substrate positioned within the housing, the substrate having a substantially planar top surface with a plurality of LEDs on the substantially planar top surface, each of the LEDs emitting light when activated;at least one first optical element positioned adjacent the LEDs and having a first entrance and a first exit, the at least one first optical element receiving the light emitted from the LEDs into the first entrance and passing the light therethrough, the light exiting the at least one first optical element at the first exit being collimated and substantially perpendicular to the substantially planar top surface of the substrate; andat least one second optical element positioned adjacent the first exit of the at least one first optical element, the at least one second optical element having a second entrance receiving the light exiting the at least one first optical element, the light exiting the at least one second optical element through a second exit of the at least one second optical element and focusing or redirecting on an area a desired distance from the second exit of the at least one second optical element.
