Abstract: An LED light module for illuminating a target plane is provided. The LED light module includes a first LED source, a second LED source disposed adjacent the first LED source, a first lens covering the first LED source, and a second lens covering the second LED source. The first lens is configured to direct first light beams emitted from the first light source to the target plane. The second lens is configured to direct second light beams emitted from the second light source to the target plane. At least one of the first and second lenses is shaped to have an asymmetrical profile. A backlighting system and a fixture incorporating the LED light module are also provided.
