Abstract: Disclosed is a novel lens for an LED light source, and a projection lamp with the same. The lens includes a reflection portion and a divergence portion. A light source is refracted by the reflection portion and then projected to the divergence portion, by which a light beam is then diverged out. The divergence portion has a flat surface side and a concave surface side, and the reflection portion is arranged on the flat surface side. The utility model has the following beneficial effects: the structure is exquisite, by using a new structural design for a focus lens, the light beam of the LED light source is reflected and refracted multiple times in the lens and then diverged, which solves the problem of large area of the LED light source, and at the same time, after being re-focused, the light beam is suitable for forming higher-brightness white light.
