Problems solved by technology

The disadvantage is that these systems are usually more expensive due to the lower intrinsic efficacy of the lamp and require complex and expensive rectifiers
While filters have been used in metal halide lamp systems to correct the color temperature of the output, chromaticity and color performance metrics have been largely overlooked

Embodiment Construction

[0020] Detailed Description of Preferred Embodiments

[0021] Figure 1 illustrates the internal components of a common fiber optic lighting device well known in the art. The illustrated illumination device is a coaxial parabolic reflector illumination system 200 comprising a light source 10 , a main reflector 40 a having a parabolic shape, a focusing lens 210 , and an output optical fiber 60 . Depending on the particular application, light source 10 may be selected from a group of light sources including xenon arc, mercury xenon arc, metal halide arc, or halogen lamps. In the illumination system 200, the emitting area of ​​the light source 10 is placed on the optical axis 80 at the focus of the parabolic reflector 40a, thereby enabling the output 20 to be collimated. Parabolic reflector 40a may be coated to preferentially reflect certain desired wavelengths. For example, in a visual application, a cool paint could be used to transmit ultraviolet and infrared radiation so tha...

Abstract

A fiber optic illumination system (100) with the output spectrum of the arc lamp (10) modified using filters (30) to reduce the magnitude of the spikes in the spectrum such that the resulting output has the desired chromaticity and color rendering index of white light.

Description

field of invention [0001] In general, the present invention relates to a fiber optic lighting system for use during medical procedures. Background of the invention [0002] During surgery, lighting is provided to allow the doctor to have a clear view. For lighting, having enough light energy will be very important in terms of correct color temperature and color rendering index values. Typically, the illumination is provided by a lamp located in the lighting unit, wherein an optical fiber bundle is used to direct the light to the operating table. [0003] In the past, halogen lamps have been used for such lighting systems. These lighting fixture systems are low cost, but typically have lower luminous flux than desired and often have a low color temperature. Higher-end systems using xenon arc lamps provide a color temperature that is closer to the desired level, almost the same as that of sunlight, and provides sufficient luminous flux. The disadvantage is that these syste...
