Abstract:
An LED module includes a circuit substrate, a light source and a lens. The light source includes first and second LEDs that differ in chromaticity. The circuit substrate is provided with conductors for driving the first and second LEDs independently. The lens includes a hollow, on a side of the circuit substrate, inside which the light source is present. An inside of the hollow is a light entrance surface. An opening of the hollow has a circular shape. The first and second LEDs of the light source are arranged to have point symmetry.
