NOVELTY - A light collection system (900) has a light concentrating device (902); and a reflective curving-surface device (904). The reflective device has an entrance aperture (906); a reflective inner curving surface (909) having a second focal region, where the two focal regions are confocal or approximately confocal within a range; and an exit aperture to transmit the second-stage output light toward a target area where the second-stage output light is received.    USE - System for collecting light (claimed) used in light energy conversion mechanism in a solar cell module or in converting solar energy.    ADVANTAGE - The system may be applied to light uniformization and heat collection of solar photovoltaic and solar thermal light collection lenses to improve the optical efficiency of a solar optical system.    DETAILED DESCRIPTION - A light collection system (900) comprises a light concentrating device (902), for receiving a portion of an incident light and forwardly emitting the portion of the incident light after concentrating and passing the portion of the incident light through a first focal region, to obtain a first-stage output light; and a reflective curving-surface device (904), having an entrance aperture (906) for receiving the first-stage output light. The reflective curving-surface device comprises a reflective inner curving surface (909) having a second focal region. The two focal regions are confocal or approximately confocal within a range so that a portion of the first stage output light is confocally converted into a second-stage output light being forwardly emitted; and an exit aperture, configured to transmit at least the second-stage output light toward a target area where at least the second-stage output light is received.
