The present invention relates to a solar collector or a light collector by means of which light, generally sunlight, can be directed onto an energy conversion unit. In particular, it relates to a light collector (10) that has an optical unit (20) and an energy conversion unit, wherein the energy conversion unit is comprised of a number of conversion cells (12, 14, 16) that are located along a first main axis, wherein the optical unit (20) triggers a refraction of light and surrounds the energy conversion unit at least partially, and the optical unit (20) focuses parallel incident light in a focal area, wherein the focal area has its largest dimension along a second main axis and the second main axis extends along the first main axis.
