Patent ID: 8434942

Claim:
A lighting apparatus for a C-arm X-ray apparatus, comprising: (a) a housing that surrounds an X-ray receiving element of the X-ray fluoroscope and does not cover a receiving face of the X-ray receiving element; (b) a plurality of light emitting diodes (LEDs) distributed evenly around a circumference of a downwards facing end of the housing, wherein the plurality of LEDs are positioned within the housing so as to surround the X-ray receiving element; (c) the plurality of LEDs being configured for emitting visible light towards an X-ray emitting element of the X-ray fluoroscope; (d) a first optical element placed over the downwards-facing end of the housing such that the light emitted by the plurality of LEDs travels through the first optical element, and wherein the first optical element refracts the light travelling through the first optical element; (e) a second optical element placed over the first optical element such that the light that has travelled through the first optical element subsequently travels through the second optical element, and wherein the second optical element diffuses the light travelling through the first optical element; (f) a focusing mechanism that allows for focusing of the light emitted; (g) a fastener for coupling the housing to the X-ray receiving element; and (h) a power supply unit for providing an electrical current to the at least one light-emitting element.
