Abstract: A light-concentrating mechanism comprises an angle-selective reflection means that reflects light having an incident angle of at least a first threshold angle and transmits at least some of the light having an incident angle smaller than the first threshold angle, and an angle-increase reflection means that reflects incident light at an angle greater than the incident angle of said light, the two means being arranged to have a gap therebetween. The angle-increase reflection means reflects, at an angle equal to or greater than the first threshold angle, at least some of the light transmitted by the angle-selective reflection means, and the angle-selective reflection means reflects the light reflected by the angle-increase reflection means and has an angle that is equal to or greater than the first threshold angle. Light is propagated and concentrated by the gap between the angle-selective reflection means and the angle-increase reflection means.
