Abstract
Abstract An artificial light source device includes a light source lamp, a reflection mirror for converting light from the light source lamp into a parallel beam of light, an optical conductor rod having a light-receiving edge surface arranged opposite to the reflection mirror such that the parallel light is guided into the rod, and an optical conductor cable comprising a large number of optical fibers, the light-receiving edge surface of the cable being arranged opposite to the light-discharging edge surface of the rod, the light discharged from the optical fibers being used as the light source.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
An artificial light source device comprising a light source lamp, a reflection mirror for converting light from said light source lamp into a parallel beam of light and reflecting said parallel beam of light, an optical conductor rod having a light-receiving edge surface and a light-discharging edge surface, said light-receiving edge surface being arranged opposite to said reflection mirror such that said parallel beam of light is guided into said optical conductor rod, and an optical conductor cable comprising a plurality of optical fibers, said cable having a light-receiving edge surface arranged opposite to said light-discharging edge surface of said optical conductor rod, the light discharged from said optical fibers being used as the light source, whereby the use of said optical conductor rod between said light source lamp and said optical conductor cable protects said light receiving edge surface of said optical conductor cable from burn-out.
Claim 2
Dependent Claim
147 words
An artificial light source device comprising a light source lamp, a reflection mirror for converting light from said light source lamp into a parallel beam of light and reflecting said parallel beam of light, an optical conductor rod having a light-receiving edge surface and a light-discharging edge surface, said light-receiving edge surface being arranged opposite to said reflection mirror such that said parallel beam of light is guided into said optical conductor rod, and an optical conductor cable comprising a plurality of optical fibers, said cable having a light-receiving edge surface arranged opposite to said light-discharging edge surface of said optical conductor rod, the light discharged from said optical fibers being used as the light source, whereby the use of said optical conductor rod between said light source lamp and said optical conductor cable protects said light receiving edge surface of said optical conductor cable from burn-out.
Claim 3
Dependent Claim
31 words
An artificial light source device according to claim 1, wherein said optical conductor rod has an end portion juxtaposed to said light-discharging edge surface, said end portion having a frusto-conical configuration.
Claim 4
Dependent Claim
32 words
An artificial light source device according to claim 1 further comprising a filter disposed between said light-discharging edge surface of said optical conductor rod and said light-receiving edge surface of said cable.
Claim 5
Dependent Claim
18 words
An artificial light source device according to claim 1, wherein said optical conductor rod is made of quartz.
Claim 6
Dependent Claim
34 words
An artificial light source device according to claim 1, wherein said optical conductor rod has an end portion juxtaposed to said light-discharging edge surface, said end portion being formed in a head-cut conical shape.
Claim 7
Dependent Claim
137 words
An artificial light source device comprising a light source lamp, a reflection mirror for converting light from said light source lamp into a parallel beam of light and reflecting said parallel beam of light, a first optical conductor rod having a light-receiving edge surface and a light-discharging edge surface, said light-receiving edge surface of said first rod being arranged opposite to said reflection mirror such that said parallel beam of light is guided into said first rod, and a second optical conductor rod having a light-receiving edge surface and a light-discharging edge surface, said light-receiving edge surface of said second rod being arranged opposite to said light-discharging edge surface of said first rod, said second rod having an end portion juxtaposed to said light-discharging edge surface of said second rod, said end portion having a frusto-conical configuration.
Claim 8
Dependent Claim
137 words
An artificial light source device comprising a light source lamp, a reflection mirror for converting light from said light source lamp into a parallel beam of light and reflecting said parallel beam of light, a first optical conductor rod having a light-receiving edge surface and a light-discharging edge surface, said light-receiving edge surface of said first rod being arranged opposite to said reflection mirror such that said parallel beam of light is guided into said first rod, and a second optical conductor rod having a light-receiving edge surface and a light-discharging edge surface, said light-receiving edge surface of said second rod being arranged opposite to said light-discharging edge surface of said first rod, said second rod having an end portion juxtaposed to said light-discharging edge surface of said second rod, said end portion having a frusto-conical configuration.
Claim 9
Dependent Claim
19 words
An artificial light source device according to claim 6, wherein said second rod is used as the light source.
Claim 10
Dependent Claim
29 words
An artificial light source device according to claim 6, wherein the light transmitted through the first rod is diffused by the second rod and used as the light source.
Claim 11
Dependent Claim
24 words
An artificial light source device according to claim 6, wherein said first rod comprises a core portion about which a clad portion is disposed.
Claim 12
Dependent Claim
17 words
An artifical light source device according to claim 6, wherein said first rod is made of quartz.
