Please see the code below, and let me know, how I can make these rings
illuminate their neighborhood?

union
{
 torus { 2.475 0.025 rotate < 0.0, 0.0, 90.0 > translate < 20.0, 0.0,
0.0 > rotate < 0.0, 000.0, 0.0 > }
 torus { 2.475 0.025 rotate < 0.0, 0.0, 90.0 > translate < 20.0, 0.0,
0.0 > rotate < 0.0, 120.0, 0.0 > }
 torus { 2.475 0.025 rotate < 0.0, 0.0, 90.0 > translate < 20.0, 0.0,
0.0 > rotate < 0.0, 240.0, 0.0 > }
 hollow
 pigment { color rgb < 0.8784314,  0.2,  0.003921569 > }
 interior
 {
  media
  {
   samples 20
//   absorption < 3.0, 4.0, 0.5 >*1.0
   emission   < 1.0, 1.0, 1.0 >*10.0
   scattering
   {
    1
    < 0.5, 0.75, 1.5 >*3.0
    extinction 0.5
   }
  }
 }
 finish { emission 10.0  }
}
