Well what u are refrerring to is the process of refraction. They would be using a convex lens. this lens has the ability to refract all the light rays which come from a far distance (known as infinity in physics) towards a common point (called focus). So obviously if all the rays reaching the lens from the sun are refracted by a convex lens they would heat up the point at which all of them converge. this started a fire. this can also be done with a magnifying glass as that also has a convex lens.
